Deep Cycle AGM 12 Volt 100Ah Battery, Maintenance-Free, 3% Self-Discharge Rate, 1150A Max Discharge Current, Perfect for RV, Solar, Trolling Motor, Wind, Marine, Camping and Off-Grid System

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.

I ordered this battery for my small RV. The unit arrived well packaged and in good condition. Be aware it's a lead acid battery, so its heavy! I had the battery connected to the RV since January 2025. It performed as expected without any issues until September. It suddenly began to discharge itself and lost capacity. I contacted the vendor, Arkpower, and they responded immediately. They had me perform some diagnostic tests to try and figure out the issue. The battery likely had a cell failure. Arkpower was very helpful and responsive. They ended up sending me a replacement battery. I will definitely purchase from this company again.

Just installed the battery a few days ago, works great! Very fast shipping! Kind of confused at first because it does not have a name on it at all, but I ran the numbers and it came up the right battery. I’ll leave a better review after I use it for six months, but so far so good.

This 5 star review is for this 100Ah battery I just installed on our travel trailer. I chose to pay more money than I would have locally because I have had good experiences with WEIZE brand in the past for a variety of uses in different size batteries. This is a HEAVY dude for an old man to carry! But of course it is a 100Ah AGM, not a lithium. I just needed a good-quality battery I felt like I could count on. The trailer will spend most of its life hooked to shore power, but when the power goes down, you need a battery you can count on. An AGM will handle colder temperatures than a lithium and does not require modifications to our RV. I really like the way the screw terminals are made and it comes with the bolts, washer and lock washer needed for an easy install or disconnect. The carry strap seemed strong and handled the weight for me. I was a little afraid it might come loose and cause me to drop the battery on my foot, but no problems. :-) It came VERY well boxed with good padding. Had about 12.75 reading on volts and quickly charged to 13.38. Since I just installed it, I cannot speak to how it will hold up or how long it will last. Fits perfect in a group BG27 battery box by NOCO. (NOCO is a nice inexpensive box.)

The battery was not operative after two weeks and when I requested a return they approved provided I bore the return postage cost of a battery weighing > 50 lbs.....1 star review. (I had bought a battery previously from the same vendor about 6 months ago and that became non operative after 6 months and outside the window of return but well below the life of a normal sulfuric acid battery) Well they reached out to me offering to help and after asking for a photographic evidence of a voltage measurement using a multimeter they approved a full return w/o having to return the battery.....5 star review (Good customer service, appreciated). (Though I will have to bear the cost of recycling= $13.00) - minus 1 star.

SCAM ALERT.....SCAM ALERT....SCAM ALERT .This was used for my back up sump pump. It was always plugged in and was never used. After 1 1/2 years it stopped holding a charge. Mind you...it was never used. I was told the warranty is only for a year. I told them it was never used. Too bad they said. You have to buy a new one. I won't be buying Weize again. Surprisingly, I received a call back from Weize customer service department. They said they would reimburse me the cost of the battery. They suggested I use Cash App or Chime or Zelle. They proceeded to tell me that to receive reimbursement I need to start by sending them additional funds which would be rerouted and sent back to me with the refund. They were very convincing and legitimate sounding. It ended up that I never received the funds. It was a scam and customer service said someone took my number from the review I submitted on the Weize web site and that is how they were able to call me. They also said this has happened a number of times. At this point I'm not sure who is telling me the truth and who is the scammer. Buyer beware....this has scam written all over it.

Legit battery that I installed in our Ice Castle to double the amp hours (think camper plus ice fishing shack). I went with this battery over lithium or flooded lead acid battery for two reasons. First, It will function and charge when cold, which is necessary for a shack that sits on a frozen lake in -20 degree conditions. Second, it won't offgas and doesn't require a special charger. My standard onboard charger has been charging this thing to 13.6V which I believe is great for this battery.

Good price showed up in two days
