Interstate Batteries12V 110 AH SLA/AGM Deep Cycle Battery 12V for Solar, Wind, and RV Applications - Insert Terminals (DCM0100) Works with 100AH battery applications

Just what I needed and items arrived on time. Work wellThank you,Michèle

This is the second one of these batteries I have purchased. In both cases it was to use with a Duracell Power Bank that has provisions for an external deep discharge 100 AH lead acid AGM battery like this. I have had the first one for about 2 years with no problems and just got the second one installed on a second Duracell Power Bank.First the obvious - The battery is as big and very heavy as you’d expect from the description. I used a dolly to roll it to where it was installed and I felt sorry for the UPS delivery person.If this is a new installation I recommend the use of a side terminal style automotive type knife switch, a 200 Amp automotive fuse, and #2 AWG battery cables (with 3/8” lugs). While the 3/8” lugs are slightly larger than optimal for the battery post, they work.I received the battery and assumed I’d have to charge it for several hours on my 10A charger before installing it, but it actually was fully charged in less than half an hour meaning it was fully charged when I got it. By the way when connecting heavy duty batteries like this in parallel, charge each separately first (at the same environmental temperature) then connect - otherwise the fully charged battery will attempt to instantaneously recharge the one that’s low when you connect it, leading to a heavy surge when connected.Batteries like this are serious potential energy hazards - read the warnings and instructions. Add a fuse, at least, in the event of a wiring short. Although 12 Volts is quite safe in terms of a shock hazard - You get a metal short across the terminal or wiring and you will have a bad day! Be warned - Wear no rings or metal watches when connecting these.The battery itself - Top quality, received fully charged, is exactly as described. The built in battery lift handles are a bit different than the picture, but not a problem. My previous experience is that in normal usage for an emergency power bank it is quite reliable.

Performance of the battery is good, my main gripe being that I bought a second a little later and its totally different, different case, different handles, different (smaller terminals), different country of manufacture. Both 2021 trademark date but one built in Malaysia, one in Vietnam. They also charge slightly differently with the same charger at the same time. This is mostly for those needing two batteries, beware...

I purchased the Pump Sentry backup system for my sump pump (see my review on that page) and am using this battery to provide power in the event of an outage. I had read a review on this particular battery that will provide 20 hours of power in the event of an outage and confirmed the math according to the specs vs other batteries. I feel confident with this purchase and bought a case to enclose the battery in for protection. Note: this battery is very heavy and difficult to move in a tight crawl space but is very worth having it as the power supply for outages. So far I haven't had any outages that required it to "kick in" but I did test it with the Pump Sentry alone and my sump pump worked fine.

Bought this battery 2 years ago, the battery holds 70% of the capacity. The big problem is that the battery almost exploded as you can seen in the video
