Why GC2 Batteries Remain a Go-To Choice
The GC2 format balances size, capacity, and versatility in ways that keep it relevant across golf carts, solar installations, RVs, marine systems, and industrial equipment
200Ah to 240Ah Capacity Range
GC2 batteries typically deliver between 200Ah and 240Ah at the 20-hour rate, giving users a solid foundation for long runtime in demanding equipment. That capacity range supports everything from daily golf cart use to off-grid solar storage and industrial floor machines.
Flooded or AGM — Your Choice
Flooded GC2 batteries offer proven performance and strong cost-per-cycle value when maintained properly. AGM GC2 batteries are sealed, spill-proof, and maintenance-free — ideal for enclosed compartments, mobile systems, and buyers who want simpler ownership with no watering required.
Built for Deep Cycling, Not Starting
Unlike starter batteries that deliver short high-current bursts, GC2 deep cycle batteries are engineered for sustained draw and repeated discharge cycles. That makes them the right fit for equipment and systems where runtime, durability, and consistent output matter more than cranking power.
Flexible Bank Configurations
A 6V GC2 battery can be part of a simple pair for a 12V system or combined into larger banks for 24V, 36V, or 48V setups. This modularity makes the GC2 format a practical building block for golf carts, RV house power, renewable energy storage, and backup power installations.
Recognized Group Size for Easy Replacement
Because GC2 is a recognized BCI group size, buyers often know exactly what they need when replacing aging batteries. That makes side-by-side comparison across brands more practical and helps reduce the risk of choosing the wrong battery format for existing equipment.
What Buyers Are Saying
Based on verified purchasesWas surprised that the batteries even came with lifting strap. Made the replacement easy.
Great set of batteries — freight shipping was easy to set up and had no issues with delivery. Cart is back to running like new.
Just what the old cart needed, fresh batteries and runs like new.
I was skeptical about ordering them online but when I saw this listing I decided to give it a shot. From the time I placed my order to when they were delivered was 8 days. The batteries arrived with no damage whatsoever and were exactly what I wanted at a good price.
Okay, these sure are expensive, and heavy, too, but they have noticeably more power than the batteries they replaced. So far I am well pleased with the way my EZ Go 36 volt golf cart performs.
They have held a charge and taken charge with no problems. Only time will tell. Fingers crossed, you'll never hear from me again concerning this purchase!
