We don't get a lot of power failures here, but we had 3 in a period of a few months a few years ago. I purchased 4 of these to provide backup power in the event of a power failure. These are connected in parallel, and feed a 2,000 watt inverter, giving me about 4.8 kWh of power. I have a power inlet, a shunt, and a 60 Amp breaker, all of which keep this thing offline. I have an interlock on the 60 amp breaker which prevents having that breaker and the mains on at the same time. With this system, I get power on all of the 120v outlets, ceiling fans, bathroom exhaust fans, and the garage door openers during a power failure. We don't get to use the stove, the dryer, or the HVAC during a power failure. We don't get to use the microwave oven, because it's 1800 watts, which puts my DC-side at over 180 amps. I suppose we could use the microwave oven since it never runs for more than about 30 seconds, and never more than about once per day. I have Anderson connectors across the batteries of two vehicles allowing me to quickly connect a second inverter across the car battery to feed energy into the system during the day with the engine running. 4.8 kWh is more than enough to power the house overnight until I can get a car back on the case the next morning. With the cars' alternators, we get about 750 - 1000 W out of the alternators - way plenty to power the house during the day, and top up the batteries. It's no Tesla Power Wall, but it's a LOT better than nothing. Review: No More Lead Acid Batteries! - 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. ## Features - Deep Cycle Battery 12V 100 Amp Hour Sealed Lead Acid Rechargeable ; Parcel: 1 x Battery (screws included, but no wire harness or mounting).

Judge would charge you with solar battery. You’ll be lock in a cell. Positive behavior would get you out in 1 year. **Q: For cycle use it is supposed to be at 14v? I thought float was 13.8v and max would be 14.8** A: I load tested this battery at 13.6 VDC charge and got 1,100 CCA which equates to 138 Ah using the 7.25 rule. There are several things to consider when evaluating the quality of a battery and so far I'm giving them an A+. The proof will be in how long they are able to exhibit this superior performance but I'm cautiously optimistic because the terminals are strong and well sealed and the plates must be very heavy due to the 60 pound weight. **Q: What is the maximum continuous discharge rating? Something like a CA(cranking amps) rating.** A: 100 Amp-Hours at the 10 hour rating is approximately equal to 110 Amp-Hours at the 20 hour rating! Storage capacity of AGM battery is that the amount of energy stored is dependent on the battery’s discharge rate. The greater the discharge rate, the lower the delivered capacity. Check Peukert’s Law. **Q: What type of battery post on these batteries.** A: Nuts n bolts with washers both flat and lock. Blots can be changed out for longer ones if needed. Great for terminal connectors, definitely not traditional car battery post connectors ## Customer Reviews ### ⭐⭐⭐⭐⭐ Backup power without the inconvenience of a backup generator! *by K***R on May 31, 2026* I use these as part of a backup power system for my house.

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! ## Frequently Bought Together - 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 - Attwood PowerGuard Battery Boxes Designed for Marine, RV, Camping, Solar and More - LotFancy 4 AWG Battery Cables, 4 Gauge 2 Feet Red + 2 Feet Black Pure Copper Wires with 3/8" Lugs Both Ends for Car Marine Solar Lawn Mower Motorcycle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/473907232-weize-12v-100ah-deep-cycle-battery-group-size-31-battery](https://www.desertcart.be/products/473907232-weize-12v-100ah-deep-cycle-battery-group-size-31-battery) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-05*
