ExpertPower 12V 21Ah Gel Deep Cycle Solar Battery, Sealed Gel Technology for Marine, Mobility Applications

I purchased the ExpertPower 12V 21AH Gel Deep Cycle Battery and I’m very impressed with its performance. It holds a strong charge, delivers consistent power, and works perfectly for long periods without any issues. The battery arrived well-packaged and was easy to install. For the price, the quality and durability are excellent. Highly recommended if you need a dependable deep-cycle battery.

So far so good. I use it in my 66 aloha travel trailer to run my water pump. Holds a long charge.

Quality product, as described and size is correct. Once installed, the batteries charged correctly.

good battery, i bought two, on different days, and both came with same charge and charge to near identical full capacity. removed one star because price went up nearly 25% after i purchased second battery. i was going to buy 2 more... oh well.

Ordered a battery from this company and it had a defect to it and wouldn’t fit. Tried to return the battery the seller wanted me to jump through hoops to return the battery to the point of telling me that I’m responsible for the shipping and restocking fee. I’ve never went through anything like this as long as I’ve been a prime member on Amazon. RUN from this company FAST!!!!

I have been using this for a little while now on my Kayak to power my Fish Finder. I had a 7ah battery but found that it would die too quickly so upgraded to this one and so far it has been good for long days on the water.

Excellent Battery

good product
