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.

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.

I installed it in a 12 volt kids drivable JEEP, hooked it in series with the junk 12v battery it came with. run time with original battery almost 40 min, added this battery with original runtime was well over 2 1/2 hours. grand son loves it.

I purchased this battery based on the size description. This battery is about a half inch taller than what is described. I have not used the battery yet but I probably need to get a smaller battery for my application. Very frustrating. Would not recommend purchasing, very skeptical on quality of battery if something as simple as the size description is inaccurate.

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

Have a pair of these in my side by side as aux batteries and had no issues at all. Have been able to run the stereo for hours along with rock lights and never fully drained them.
