WEIZE 12V 100Ah Deep Cycle Battery, Group Size 31 Battery for RV, Solar, Camping, Cabin, Marine and Off-Grid System, 1150A Max Discharge Current, 3% Self-Discharge Rate

Well built, quality AGM battery holds charge well and performs as well as expected. Beats the hell out of standard lead acid battery for a better relative price. We have a lot of employees who use our equipment and couldn’t be bothered to check fluid level which led us to buy these and I couldn’t be any happier. Seriously, get away from the distilled water fill ups and gain freedom by opting for some of these. You won’t regret it.

I bought two of the 100 amp hour, 12v, agm batteries about 2 years ago for an off grid (boondocked) rv on our property in the mountains and have them connected to two 150 watt solar panels. I have had absolutely NO issues with the batteries and they power everything we need to camp, including providing power to a 700 watt pure sine wave inverter that we use intermittently for our 120v appliances (crock pot, TV...). The battery is heavy, but we do not carry them around so no big deal. I just purchased 2 more for my main rv (full time use), due to price of these I decided not to go lithium just yet. These came charged and showed 12.3v when I connected them up to my system. I have my charger set to: 13.8 (2.3v per cell) for float and 14.4 (2.4v per cell) for cyclic charging. Very happy with the brand and quality!

There are a couple other brands available for more, but this Weize 100Ah battery looks and performs very well. I bought two for emergency backup power to the run the furnace and fridge for a short time in a condo setting where gas generators aren't allowed. I would recommend these over flooded deep cycle as they're cleaner and more durable. Gel batteries won't handle high current and and there's not much information about hybrid gel batteries out there. Those seem like modified AGM batteries, but not sure of the pros/cons for the extra money. To protect my investments, also bought a trickle charger. The LiFePo batteries look superior, but I'm not cycling, and this is just for emergency backup. Just couldn't justify the price. Without the extra BMS circuitry, these AGMs should just "work" when I need them to.

The battery was measured at 13.2 volts on arrival and was packaged very well. So well packed that I saved the packaging for future use. Pictured is the battery attached in parallel with two other Sealed Lead Acid batteries used to store energy on my experimental 12volt solar system. All my batteries are sealed valve regulated lead acid batteries. (You should never use a lithium battery in parallel or series with a lead acid battery because of different charging characteristics. Doing this is likely to cause a fire and ruin the batteries). I also think this battery will work well with the trolling motor on my boat. I am extremely happy with it especially getting a discount on its purchase.

This is an excellent product that works great for me, so far.

I installed 2 of these in place of 1 dead battery in my 5th wheel camper last year. I was planning (and took) and month long cross county camping trip and was making sure I had extra power if I needed it. I really never did but it was good to have them anyway. On another trip we were informed that the power would be shut off to the campground for 8-10 hours for maintenance. Power went off at 7 AM and I turned on the inverter to power my residential refrigerator. It was still going strong after 6 hours when the power came back on. Very happy with the extra power.

This sucker was bigger than I expected. I wanted a deep cycle battery for a solar system. This one is 100 amp hours, so good for powering an inverter producing about 750 watts. It was heavy as packaged. At least the battery itself includes a carry handle which helps. A warning, though…. If you want to set up a solar system and use an inverter to produce AC current, you will either need a larger battery or several small ones wired in parallel. For 2,000 watts, a 400 amp hour battery capacity is the ideal, and those batteries are expensive. This one is affordable, but to buy 4 would add up fast. An FYI if your intention is to use this with an inverter to produce AC power for appliances.

I had an issue with the battery and the weize customer support contacted me and I thought the issue was taken care of only to find out that they sent text message out to my son and daughter-in-law asking about the order that I had placed with them. They have no business contacting anyone but me. I have asked them multiple times on how they got the phone numbers and why would they contact them. I get message avoiding my questions and I am tired with dealing with them. If you value your privacy, I would not do business with this company!
