Great battery for my 12volt solar system. Very nice. Works well. Came 3/4 charged so be sure to charge fully on charger before using to maximize capacity for the future.

Great battery so far. It’s being used as an external battery for a ventilator while out and about and for emergency power for the patient. He can’t initiate breaths on his own so it’s essential for him to have power for the ventilator. The medical supply company only gives you a small 35ah battery that only last about 8-9 hours. If you want an optional bigger higher AH battery you have to purchase it on your own. This battery should last a full 24 hours before it needs a recharge that’s plenty of power for going out in the community and in the event we have a power outage and need backup power. It came well packaged and about 65% charged. The battery took a charge well and held its voltage after. I bought a group 29-31 battery box but I think I could’ve gotten away with a group 27 battery box however I’m not certain of that.We haven’t used it a ton yet but so far so good I ran the ventilator on the battery for over an hour and no issues and the battery provides stable voltage. I’ll update further if I have a reason to.

This large-ish battery arrived not fully charged, but I was pleased to find that it was probably at over 60%, maybe as much as 80%, because it didn't take long at all to charge, although admittedly I did buy a fantastic charger / UPS to use with it, so that may be why. The battery was packaged very well for shipping. I will likely buy several more of these.

It appears to be well made and easy to connect to a sump pump backup inverter. Tome will tell how it holds a charge and recharges.

This could be the best battery ever! I use this to run my icehouse and it does a great job. I often run it for 48 hours before charging and it is still at over 50% charged.

Great battery hold the charge good👍 and deliver a constant backup power supply

This is a great example of why you should NOT buy batteries off Amazon and online! This battery came late and did not work and wouldn’t take a charge! The seller has been absolutely no help and after several days of messaging back and forth and me doing everything he asked. He wanted me to go out and buy a special charger!!!!!! I had already bought a special charger, specifically for this battery and it didn’t work! The seller wanted me to buy yet another special charger to FORCE it to take a charge…. In his words. Save your money and buy local!

I purchased a battery from Weiz. I was given the wrong measurements, so the battery did not fit. After several conversations with them and realizing they did not offer a battery that would fit, they sent me a return label and a refund minus the reshelving fee. The company worked well with me, and I appreciate their professionalism.
