Overland Cart 24V 21A-24A Battery Packs

Overland battery powered electric carts use sealed lead-acid batteries.  The batteries are rechargeable and replaceable.   Overland has researched the best options on the market to ensure top performance and top quality.  This post will walk through how Overland 21A-24A battery packs work, how they can be replaced, and where to buy them.

Overland 24V, 21A-24A Battery Packs
Overland Battery Packs consists of TWO 12V batteries in series.  These two batteries are held in a steel case that provides a stable connection to the cart.  The most important thing to do before attempting to replace the batteries or battery pack is to verify the size of your battery pack.  The best way to do this is to remove the battery pack from the Overland Cart and check the graphic on the front of the battery pack.  The Amp Hr rating will be indicated on the front graphic.  The most common battery pack sizes are | 24V, 12A | |24V, 21A| – |24V, 22A| – |24V, 24A| and |24V, 39A|.  The 24V, 21A-24A battery packs are the focus of this blog post.  The graphic on the front will look like one of the two options.  This is the older version.

This is the new graphic on all of our battery packs.

Where can I buy batteries?
One of the Overland selling points is the easy battery replacement.  OEM replacement batteries can be purchased through Amazon, BatteryStuff.com and most local battery supply stores.  Over the years we have put three different sizes of batteries into our 21-24 Amp Hr battery packs.  This has largely been due to the availability of batteries.  We have offered |24V, 21A| – |24V, 22A| – |24V, 24A| battery packs in the past.  These are all what what we would call “nominal” batteries capacities.  They are close enough in size that they can all be used in the battery pack without issue. The 21A and 22A have terminal connectors with bolts and the 24A batteries use terminal connectors with screw mounts.  Either type of connection will work.  We recommend upgrading to the Hitachi/CSB 12V, 24A batteries.  They offer superior performance and life and are compatible with both the 21A and 22A battery packs.

The 12V, 21A battery can be found on Amazon here: PSH12180FR **Two batteries will need to be purchased.**
The 12V, 24A battery can be found on BatteryStuff.com:
EVH12240 **Two batteries will need to be purchased.**

How do I replace my batteries?
Our Overland Cart Owner’s Manual for carts with 24V, 24A Battery Packs provides step by step instructions to replace the batteries.   View the manual.

We also offer Overland Cart Owner’s Manual for older carts with the 24V, 21A/22A Battery Packs. This provides step by step instructions to replace the batteries.  View the manual.

Do you have a spec sheet for the Powersonic batteries and CSB Batteries?
Yes, you can view the 21A battery spec sheet here: Powersonic PSH12180FR Spec Sheet
You can view the 24A battery spec sheet here: Hitachi/CSB EVH12240 Spec Sheet

Can I buy a battery pack direct from Overland?
Yes, if you would like to buy an extra battery pack or a replacement battery back, you can purchase it online: Overland 24V, 24A Battery Pack.  We also sell individual batteries over the phone: 877-447-2648

How many hours does the extended range battery pack last?
Under normal use in normal conditions, the battery pack will provide 6-8 hours of continuous use.

How long does it take to charge the battery pack?
The 24V, 21-24A battery pack takes 6-8 hours to charge fully.   Overland recommends leaving the charger on over night.

Can I overcharge the batteries?
No, the battery management system on the charger prevents overcharging.  The batteries will reach their maximum charge and then the charger will stop supplying a charge.

What’s a battery cycle and how many cycles can the battery handle?
A battery cycle happens when a battery is charged, experiences a level of discharge, then is recharged.  This can be done hundreds of time over the life of the battery pack, but every battery does have a limit.  Overland puts an estimated total life of 300-500 charge/discharge cycles.  It’s recommended to recharge the battery pack after each extended use or at the end of the day.  This maximizes the health of the battery pack and ensures you get the most possible cycles out of the battery pack.

Do you offer a warranty on the batteries?
Yes, we offer a one year warranty on the batteries.  This is included with the Overland Cart Standard Warranty.  For warranty issues, please contact us via email: support@graniteind.com or by phone: 877-447-2648.

What charger do I need?
The 24V, 5A extended range charger is the standard charger for the any of the 21A-24A battery packs.  However the 24V, 21A-24A battery packs can use either the standard 24V, 2A charger OR the extended range 24V, 5A charger.  There is a charger built in to each Overland Cart.  If a battery pack is purchased as a back up, an extra charger will also need to be purchased.


Does it matter which charger I buy?
Yes, if the extended range 24V, 5A charger is used on standard battery pack (24V, 12A) it will push too much electricity through the batteries, which is extremely dangerous.  If the only battery pack used is an extended range battery pack, then either charger will work.
