    • Working Fine, Happy with the Price
Edition: 1 Pack
Someone gave me one of those wally world EverStart jump boxes. The 1200 amp all-in-one wonder with the tire pump, light, USB, cig lighter (power ports), and jump-start feature. The battery was dead and they were going to toss it. I cracked it open and found this series of battery in it. So this purchase was to hopefully put the jump box back into service. Always wanted one, but too cheap to justify the cost for something that I 'might' use on occasion. Happy to find this AGM battery and at this price. I don't buy any acid-flooded batteries anymore as no matter the name brand, they all eventually leak at the terminals and corrode the connection. Installed this battery and put the jump box on a charge for a couple of days. The following week I actually had a real-world test for it. My old garden tractor had a flat dead battery in it. Grabbed the jump box and cranked on the garden tractor for awhile to get fuel up to the carb. Then it fired off no problem. A small twin-cylinder gas engine, so not something like a big V-8 or a diesel, but I was impressed with how long this battery did crank, even after the jump box 'low battery' light had come on. I didn't crank it until the battery was flat dead, so do not believe I damaged it, just gave it a workout. Back on the charger, it reached full charge indicated just fine. Also used the built-in air pump to air up one of the front tires on the garden tractor. No problems there either; as expected. Battery is working fine. Hopefully it lasts several years. I'm considering cycling the jump box charging cycle (with a cheap mechanical plug-in timer) as these cheap EverStart jump boxes documentation online gives no details on if it has a built-in float charger or if it is just trying to cram in amps 24/7. ... show more

    • This has rescued my Schumacher XP2260W Instant Power jump starter
Edition: 1 Pack
I've had this Schumacher Instant Power jump starter pack for a lot of years and it has saved my bacon plenty of times. I worked solo for a lot of years in very rural locations... places where you don't want to deal will a dead battery because you left the lights on or your battery was on it's last leg and wouldn't start the vehicle on a chilly morning. I had it rigged so the jump starter pack would be charging whenever I was driving from location to location. The battery power always read 100%. But after years of rugged use, the battery power indicator started to show below 50% and even lower and eventually went to 0. I could never get it back up to a full charge. After a complete test of the battery I concluded the Schumacher unit was still fine but the battery had seen better days. Looked on amazon for a replacement based on battery type and dimensions. This one is a perfect fit. It's a bit of a challenge to get the battery cover off the the Schumacher unit but the swap is easy and I am back in business. I did think about replacing the entire unit because I have used in many different ways for a lot of years, but looking at the replacement cost made trying a replacement battery the easy choice. ... show more
