ExpertPower 12 Volt 20 Ah EXP12200 Rechargeable SLA Battery

I needed to replace the battery in my Stanley jump-box, the 55/1000A, midsized version.It came with a 19AH battery and this one is a 20AH battery, so I wasn't expecting much of an upgrade.To my surprise, it made a big difference. I'm not sure if the 19AH that the battery it came with was a complete exaggeration or the hole in bottom of my battery has been there a lot longer than I think.I've been having some problems with my Mazda rx8 starting and the jump box would say it was fully charged and after a couple seconds of cranking it would no longer even be helping, let alone be used more than once, so I figured it was time it needed to be replaced. When this battery was delivered, I took apart my jump box and that's when I found the hole in the bottom of the battery.This battery fit in there perfectly no alterations were needed, before charging it, I hit the test button and it showed two out of three lights, so I plugged it in and topped it off.It sat there for about two weeks before I was able to diagnosis I had a bad coil, replace it, spark plugs and wires. Since the battery that was in it it's only a couple months old I knew I'd need the jump pack still to start it because of all the cranking I did prior to replacing the coil.If you know anything about mazda rx8, you know that you can still flood the engine in a modern car and before I did the repairs, apparently that happened so I was cranking on the jump box a lot trying to do the clear flood procedure. After I performed the "clear flood procedure", it fired right up.My best guesstimate is I was cranking on it for about 30 seconds straight, then another 30 seconds, without waiting a minute in between for it to recuperate. I could tell the flood procedure that's just about to complete so I stopped cranking waited 30 seconds and then I started cranking again, for another 10 or 15 seconds before I was completely sure that the "clear flood procedure" was complete. This is when I initially tried to start the car want the repairs and the flood was cleared it still started the car better than the three-month-old battery when it was brand new which was a surprise since I had been cranking on the engine for so long.After I got the car started, disconnected the box I hit the battery status button and it still had three lights, showing it was a fully charged pack. I knew that it had to use some of the juice, so I took it inside and plugged it in anyway. To my surprise, the light stopped flashing but then an hour which it usually takes lot longer to charge the pack from 1 or 2/3 of lights power.Since then, it's been sitting around and I through a battery tester on it and it was still at 14.4V.For battery to replace the one that your jump box or jump pack came with and you're not trying to start a v8 (which I don't know about. this one very well could as the jump boxes original factory battery was only 19AH and it had no trouble starting a v8)Anyways, this is a great battery for your battery pack, but if I had a v8 and may have opted to spend the extra $9 and got the 22AH but seeing as how I no longer have a v8 in my life nor do I have 9, zero-turn mowers I need to worry about getting started every morning, 6 days a week anymore, I was confident the 20A battery was going to do just fine for my needs and so far so good, if anything should change I'll come back and update my review, but I am very happy spending $40 on this battery versus spending $150+ to buy a brand new jump pack with the same capabilities.

Worked great starting my generator. Better than the original

I am about to replace one I bought 5 years ago. It has spent that whole time outdoors in an unsealed plastic battery box, powering a water fountain and an Arduino-based controller and being charged by a solar panel. It would probably still be working now, but a failed panel connection caused the battery to be badly discharged for a long time. No lead-acid battery would survive that.I notice that the bolt-type connections on mine have been replaced by the tab-with-a-hole type. Not great for me, but it depends on how you will use it.

it's a good deal

Great battery for the price. Used it for ~5 years in my 200W portable speaker before it started having issues. I bought the same battery again, charged it once, and it goes weeks without having to recharge now.

Fit my mobility scooter perfectly

This battery only lasted 1 year and 9 months and would no longer charge! This was my experience with this particular battery! I couldn’t tell when it was manufactured so maybe it’s been sitting in the Amazon warehouse for 2 years till I placed the order and this was the battery that was sent to me because I had ordered from amazon before I just don’t remember what brand it was and it lasted me 5 years of use!

battery has higher amp/hr than original fits perfectly
