How to Replace the Batteries in a Cricket Golf Cart

To replace the batteries in a Cricket golf cart, shut down the cart and charger, disconnect the old pack, and install compatible batteries using the wiring diagram for your model. The cart’s model, pack voltage, and battery chemistry determine what you can install, so don’t copy another golf cart’s cable layout. Before buying replacements, check whether the batteries actually need replacing, and whether they qualify for warranty service.

Understand Your Cricket’s Battery Pack

Matching the cart’s voltage is necessary, but it does not by itself make a battery compatible.

Replacement batteries must also fit the compartment, connect correctly, supply the cart’s operating current, and work with its charger. A battery that fits physically can still be the wrong choice.

Identify these details before ordering:

Cart model and model year: Use the identification plate or purchase paperwork.
Total pack voltage: Confirm it from the cart documentation, not just an individual battery label.
Battery chemistry: Look for wording such as sealed lead-acid, AGM, gel, or lithium.
Battery arrangement: Record the number of batteries, their individual ratings, terminal positions, and cable routing.
Charger compatibility: The charger must support the replacement pack’s voltage and chemistry.

In a multi-battery series pack, the cables between batteries are interconnects. The main positive and main negative connections are the pack’s output connections to the cart. Distinguishing those connections matters when disconnecting the pack safely.

The procedure below is for a like-for-like replacement. Changing battery chemistry or pack voltage is a conversion, not simply a battery swap.

How to Replace the Batteries in a Cricket Golf Cart

A correct replacement begins by confirming the fault, matching compatible batteries and wiring, and shutting down the cart before handling connections.

Step 1: Confirm the Fault and Check Warranty Coverage

Have the charging system and batteries assessed before buying anything. Poor range or a cart that will not move can result from a charging fault, damaged cable, or loose connection, not necessarily worn-out batteries. A resting voltage reading alone does not establish how well a battery performs under load.
Use the required test for a warranty claim. For its Cricket battery warranty claims, Cricket Mini Golf Carts requires diagnosis with a Battery Load Tester, not a multimeter. Have the selling dealer arrange the appropriate test for the installed battery chemistry.
Check purchase and registration records. For carts purchased directly from Cricket Mini Golf Carts, Inc. in Daytona Beach, the warranty table lists a 5-year battery warranty for model years January 2023–current. The cart and batteries must have been registered within 90 days of purchase to activate that seller’s 5-year bumper-to-bumper coverage. Eligibility still depends on the warranty terms; older model years and purchases from other sellers can have different coverage.

Keep the purchase receipt, registration confirmation, battery labels, and test results available. Contact the seller before removing batteries that might qualify for a claim.

Your Situation	Appropriate Route
The existing pack matches the cart documentation, and you want the same battery type	Select a compatible, like-for-like replacement
The battery labels, cart voltage, or wiring are unclear	Identify the installation before ordering.
You want to change battery chemistry or total pack voltage	Have the complete conversion checked for compatibility before proceeding
A battery is swollen, leaking, unusually hot, or physically damaged	Stop using and charging the cart; arrange professional battery service

Step 2: Match the Replacement Batteries and Wiring

Get the correct diagram before disconnecting anything. Cricket provides battery instructions covering all 36V Cricket models. The Cricket ESV 24-volt model has a separate ESV wiring diagram. Match the diagram to the model on the cart’s identification plate or purchase paperwork and the pack voltage in its documentation.
Match the battery specifications. For a like-for-like replacement, confirm the specified chemistry, individual battery voltage, capacity, dimensions, terminal type, and terminal orientation. If the proposed battery differs from the original, confirm its compatibility with the cart before proceeding.
Check the complete installation. Make sure the hold-downs will secure the batteries, the cables will reach without stretching, and the terminals will clear the case or seat structure. Confirm that the existing charger supports the replacement batteries.
Have the replacement battery manufacturer’s terminal torque specification and a suitable torque wrench ready for installation.

Do not assume the wiring currently on the cart is correct, especially if a previous owner modified it. Photographs are useful records for tracing the connections.

Step 3: Shut Down the Cart and Prepare the Work Area

Secure the cart. Park on a level, dry surface, apply the parking brake, and chock the wheels. Turn the key off and remove it.
Disconnect charging power. Stop charging and disconnect the charger before unplugging its cart-side connector, if fitted. With an onboard charger, disconnect the external power cord.
Complete the model-specific shutdown before handling the connections. If a lithium battery has a power switch or shutdown procedure, use it before handling the connections.
Prepare yourself and your tools. Wear eye protection and suitable gloves; use acid-resistant gloves when handling lead-acid batteries. Remove rings, watches, bracelets, and other metal jewelry. Have insulated tools, a suitable torque wrench, cable labels, terminal covers, and an appropriate battery-lifting aid available.

Work in a ventilated area away from flames, smoking, and sparks. Never rest tools or loose hardware on a battery.

Turning the key off does not make the battery terminals electrically dead. A tool bridging terminals can cause severe arcing and burns, and disconnecting the cart does not remove the energy stored inside each battery.

Step 4: Open the Battery Compartment and Label the Cables

Expose the batteries using the access arrangement for your model. Secure any raised seat or cover so it cannot fall while you work. If the battery case must be removed, identify any attached wiring and label its connections first. Do not lift a case while its wiring remains attached.
Photograph the installation clearly. Capture the entire pack, every terminal connection, cable routing, interconnects, and any separate charger or accessory leads.
Label every connection. Mark each cable with its destination and polarity. Identify the pack’s main negative and main positive terminals from the diagram, not merely from cable color or proximity to the controller.
Resolve discrepancies before proceeding. If you find unidentified wires, added accessories, missing terminal protection, or wiring that disagrees with the diagram, have the installation checked.

Record which leads share a terminal. Missing a charger or accessory lead during reassembly can create a second problem even when the main battery cables are correct.

Step 5: Disconnect and Remove the Old Batteries

Disconnect the pack’s main negative connection first. Remove the cart-side lead or leads from the identified main negative terminal. Insulate and secure the disconnected ends so they cannot spring back onto the terminal.
Disconnect the main positive connection next. Protect that cable end in the same way. Keep every removed lead separated from exposed terminals and metal parts.
Remove the remaining interconnects and auxiliary leads according to the diagram. Keep the labels attached. Other batteries and terminals remain live even after the main cart cables are disconnected.
Remove the hold-downs and lift out the batteries. Use the battery’s approved handles or a compatible lifting aid, with help where needed. Never lift a battery by its terminal posts, cables, or lid. Keep lead-acid batteries upright.
Inspect the empty tray and cables. Remove loose dirt and debris. Replace damaged cables, badly corroded lugs, or cracked terminal covers before installing the new pack. Structural corrosion or evidence of an acid leak needs attention before the cart goes back into service.

The main-negative-first sequence applies to the conventional replacement arrangement described here. A lithium system with a prescribed isolation or precharge procedure must use its battery-specific service sequence.

Step 6: Install and Reconnect the Replacement Pack

Position and secure the batteries. Orient the terminals to match the correct diagram. Refit the hold-downs without distorting the battery cases. Cables should reach naturally, without pulling on terminals or rubbing against moving parts.
Install the interconnects and auxiliary connections in the documented arrangement. Keep the main cart connections isolated while assembling the pack. Do not improvise a series or parallel layout.
Check the wiring before completing the circuit. Compare every connection with the model-specific diagram and the cable labels. Confirm the location of the main positive and negative terminals. If you cannot confidently establish pack polarity, stop and have a technician verify it.
Reconnect the main positive lead, then the main negative lead last. For a lithium installation requiring precharge or another special connection sequence, complete that manufacturer-prescribed procedure instead. Do not improvise a precharge method.
Tighten the terminals to the replacement battery manufacturer’s specified torque. Use the correct hardware and a suitable torque wrench. Make sure each cable lug sits flat and cannot rotate once tightened, then refit the insulating boots and terminal covers.

Do not turn on the cart if a cable becomes hot, a connection arcs heavily, or anything appears inconsistent with the diagram. Stop work and arrange service rather than repeatedly attempting the connection.

Step 7: Reassemble, Charge, and Test the Cart

Make a final visual inspection. Remove all tools and loose hardware. Confirm that the batteries are secured, cables are supported, and nothing will be pinched when the case or seat closes.
Reinstall the case, covers, and seat. Secure their fasteners and latches. Restore any service switch and battery power switch to their operating positions using the required startup sequence.
Charge the pack with a charger that supports the replacement batteries’ voltage and chemistry. Allow the charger to indicate a completed charge; do not substitute a generic charging-time estimate.
Disconnect charging power before testing the cart. In a clear, level area, test starting, stopping, and low-speed operation.
Arrange proper battery recycling. Keep old battery terminals protected against accidental contact and keep lead-acid batteries upright. Take them to a battery retailer or approved battery recycler that accepts the chemistry involved. Do not put them in household trash or curbside recycling. For damaged batteries, obtain handling instructions before transporting them.

Replacing One Battery or Switching to Lithium

Test the complete set before replacing one battery, and confirm compatible components before converting the cart to lithium.

One Weak Battery in an Older Pack

Replacing only the weakest battery may not restore useful range if the rest of a series-connected lead-acid pack is also worn. The pack’s usable performance is constrained by its weaker batteries, and mixing substantially different capacities or conditions can lead to uneven charging and discharge.

Have the complete set tested before deciding. A single replacement can make sense when the other batteries are relatively new and test well, but an aging set generally needs a matched replacement set rather than a succession of individual swaps.

Do not mix battery chemistries within the pack.

A Lithium Conversion

A lithium conversion needs more than a battery that fits the tray. A lithium conversion requires compatible components, including:

Pack voltage and controller operating requirements.
Battery-management-system current capability.
Charger voltage and charging profile.
Cable, fuse, mounting, and terminal arrangements.
Battery gauge or state-of-charge display, where applicable.

Confirm that any lithium pack is compatible with your cart model before installing it.

Do not assume the old lead-acid charger is suitable simply because its nominal voltage matches the new battery.

Confirm the Replacement and Prevent Early Failure

A successful replacement should provide normal operation without battery warnings, charging faults, or intermittent loss of power. If trouble remains, avoid assuming that another new battery will solve it.

A hot cable connection can indicate excessive resistance. Intermittent operation can come from a loose connection or another electrical fault. Stop using or charging the cart if you notice abnormal heat, swelling, leakage, smoke, or an unusual odor.

To protect the replacement pack:

Keep the compartment clean and dry, with cables supported and terminal protection fitted.
Keep the batteries securely restrained so movement does not strain their connections.
Do not open sealed lead-acid or lithium batteries to add water. Watering applies only to serviceable flooded lead-acid batteries, using their specific maintenance instructions.
Use the battery maker’s charging and storage procedures rather than transferring habits from a different battery chemistry.
Investigate declining range or charging faults instead of repeatedly running the cart until it stops.

If a fault persists, leave the cart out of use and seek service.

Frequently Asked Questions

Can a Completely Dead Golf Cart Battery Be Recharged?

Sometimes, but “dead” can mean discharged, internally damaged, or electronically shut down. A deeply discharged lead-acid battery may have permanent capacity loss, while a lithium battery may need its manufacturer-approved recovery procedure after the battery management system disconnects it. Have the battery assessed with the correct equipment; do not bypass the charger or lithium protection system to force a charge.

Can I Use a Car Battery in a Cricket Golf Cart?

A conventional car starting battery is not an appropriate substitute for a golf cart’s specified traction battery. Starting batteries are designed primarily for brief, high-current engine starts rather than repeated propulsion discharge cycles. Use a battery that matches your cart’s documentation.

Why Won’t the Charger Start After I Replace the Batteries?

The charger may lack AC power, have an incomplete connection to the pack, detect an incompatible battery, or fail to recognize the pack’s voltage. Check its indicators and the charging connector without opening live equipment. If the batteries were just replaced, have the charger leads, pack wiring, and charger compatibility verified before attempting another charge.

How do you safely disconnect a Cricket golf cart battery pack, including a lithium pack?

Turn the cart off, remove the key, and disconnect charging power before handling battery connections. For a conventional pack, disconnect the main negative connection first, then the main positive connection, insulating and securing the disconnected cable ends. A lithium pack with a prescribed isolation or precharge procedure must follow that battery-specific service sequence instead. For a Cricket lithium battery, consult the lithium battery owner’s manual.

How should you wire replacement batteries in a Cricket golf cart?

For 36V Cricket models, use Cricket’s battery instructions for all 36V models. For a 24V Cricket ESV, use its separate ESV wiring diagram. Orient the batteries as shown, install the interconnects and auxiliary leads in the documented arrangement, and keep the main cart connections isolated while assembling the pack. Verify pack polarity before connecting the main positive lead and then the main negative lead, unless the lithium battery requires a different prescribed connection sequence.
