Seems to be doing ok, I had to file a little out of the inside of the case for it to fit right.

Great replacement for the OEM battery in my laundry weigh scale. My commercial weigh scale for my dry cleaning shop was brand new, but somehow was turned on and left unplugged, which drained the battery completely. The battery wouldn’t take a charge whatsoever after that, so I needed to find a replacement rechargeable battery. I didn’t have high hopes because it was such a strange battery, but had one that was close enough in specs to work. I had to get out the soldering iron, but I was successful at swapping out the OEM battery for this replacement. I charged it up overnight and tested it the next morning. SUCCESS!!! So happy with this purchase. Would recommend this to others looking for a replacement battery with these specs.

Like a couple other reviewers I had to slightly modify my Fi shock ss400 to get the battery to fit. Had to stop of about 1/4 in of two ridges in the case at the top of where the battery slides in. Works fine. Fits with modification.

It mostly fits my Fi-Shock ESP-2M fence charger but the terminals were too wide. A little utility knife action in the plastic battery enclosure and I made it fit. They also attached the brand sticker squarely over the battery specs when any of he other themree sides would have been better.
