12V 20AH Rechargeable Sealed Lead Acid (SLA) - Nut and Bolt Connector - Replaces Jump Starter Battery

This battery worked fine for the Harbor Freight Battery Jumper Emergency kit. It was fully charged when it arrived in good condition. Instilled easy but the jumper started draining the battery right away. The next day I checked the battery charge level and it was down from when it arrived. twice I have checked this and there is something in the jumper box that is draining the battery. It may take days for it to drain down to an unusable level so Keeping it plugged in is what I am having to do. But again. The battery arrived fully charged. It fit, it was undamaged and arrived on time.

So far, so good. Came charged at 13.0 volts out of the box. Ships in the OEM packaging which constitutes a cardboard box holding styrofoam top and bottom to protect the battery. Worked well enough. Battery came with plastic protectors for the positive and negative terminals. Put it on the charger and it got to float within a few minutes. As long as it lasts like it should, it seems like a good value.

This works well as a small automotive stereo power source. It was used on a tricycle for mobile audio. It was charged and discharged many times with no problems. I like the battery terminals. Easy to hook up multiple wires to.

This seems so far to be a very good battery, price, and delivery. I am using it in an electric scooter. The previous battery showed a bigger drain when going up a hill than this one . It's not too hard to install, but the small nut and bolt when used in a tight place made me say 4 stars rather than 5 in that category. I am pleased to find out about this battery and to do business with this company and seller.

I bought this battery to power the mount on my telescope.It came with a full charge.It is more than enough to do the job.Well made,fast delivery,no worries about spilling acid. I would definitely buy this again.Batteries of equal size at the auto parts stores are double in price.

rejuvenated my jumper box air compressor combo! Almost a direct replacement, fit close enough for me.

I bought two of the 20 amp batteries for two different jump starters that I have I put them both together and ended up using one of them the very next morning and it work just wonderful I hope they hang in there cuz I'm very happy with them so far

Works very well.
