Weize 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.

The batteries are of great quality and very affordable. I had bought 3 of them to chain to my solar generator. They worked awesome! I had so much more capacity on my generator. However, after a while (about a year), they were not holding 100% of the charge. I contacted the tech support of the solar generator company and they thought that the batteries (one or more) could have lost some efficiency. So, I contacted Weize about this issue and asked if they would be able to help. I also asked them about the warranty. The customer service was so outstanding. They got back to me right away even though it was a Saturday. They asked me questions about the problem, gave me suggestions to hopefully resolve the issue. I wasn’t expecting a refund or a replacement. I was just happy that their assistance was so prompt, professional and kind. But, eventually, they gave me an option of a refund or replacement. I chose a replacement because the batteries are great, no matter what. Sometimes, issues come up with any product or it can be a combination of different things (thus, the warranties). They set up the replacements promptly. I’m so looking forward to using these batteries again. I am so happy with the batteries, the warranty and the customer service!

These batteries for my husband’s motorized chair were such a great bargain. Price was excellent and he has already gotten many hours of use.

UPDATED 2 MAY 2021: As I mentioned in my original post we boondock 90+% of the time. Since my original post I purchased two more of these batteries. I now have three of these batteries installed in parallel in our travel trailer. I installed three REC 330 watt solar panels along with a Victron Charge Controller and 2000 watt AIMs inverter. Additionally, I installed a MicroAir Soft Start in the Dometic 13500 BTU A/C system. All items except the solar panels were purchased on Amazon; Amazon does not have a seller for the panels. I am providing this system background so you understand the following experience with these batteries.Now for the results of multiple boondocking trips: These batteries provide all the power I need in the trailer. I can run the microwave, refrigerator and even the A/C. I use a CPAP at night on 120 Vac. These batteries get a real workout everyday. I have run these batteries down to 30% charge (about 8 Vdc) and they come back every time to full charge with a few hours of sunshine. Yes, the solar power does add power for the daily usage; the charge controller uses any excess power to assist in running the appliances in the trailer when it is not needed to charge the batteries. So, far these batteries have proved themselves to be reliable under heavy usage and take a beating without failure.I highly recommend these batteries.Original Post:I bought this battery for use in a travel trailer when we are boondocking (dry camping with no power) to provide a limited amount of 120 VAC power via the inverter. The trailer came with a single type 24 battery. This battery is described as a type 24; However, it is much larger than a typical type 24 battery and would not fit in a type 24 battery box. So, I returned the battery box and purchased a larger dual battery box that would hold the current type 24 battery and this one. If I was attempting to use two of this battery a very large battery box would be needed. The battery does what it is supposed to do. Have not yet used it for dry camping which is what it was bought for, will update after our first trip.

Super fast shipping, worked perfectly and are better than the ones that were in it when they were new.

Fit well in the scooter and was partially charged to be able to verify functionality. Works well.

I received the order and put them the Jazzy mobile wheelchair. After charging for 14 hours unplugged and there was no charge. The wheelchair light would only turn on if plugged in. I submitted a request to return and followed the instructions that were provided by Amazon. UPS wanted $130 to ship the product back. The seller had instructions that if shipping costs more than $30 to call a phone number for other instructions.I called the number and was originally sent to voice mail. They called me back within 30 minutes and I gave them the order number and they told me that they would contact me with instructions within 24 hours on how to be refunded. They contacted within 48 via text and then email. They asked me to check the voltage with a meter and to submit to them the amps that the charger on the wheelchair produce. They wanted a picture of the voltage check. I check the voltage and sent them a picture of what they had requested.A couple days past and then they asked me to perform more tests and submit those pictures to them. Bottom line don't hassle with buying from this seller. You will get the run around and who know if you will be refunded the amount of the purchase.

Good battery!.. does what it’s supposed to…
