2-Pack UB12100-S Universal Sealed Lead Acid Battery Replacements

Amazon Customer: These were a perfect for a pair of 2004 24volt scooters. They have held up so far and I hope they continue to work as well for a long time.

Elysia Hudson: Horrible product! I bought these batteries as a replacement for my Neuton CE 5.2 LawnMower. Assembling the batteries was easy, but just after one use the batteries stopped working and could not hold their charge. Tried to contact the seller and there was no response!

moregreatstuff: Yeah, I have a cr@ppy little Neuton battery mower. Works well enough for my small lawn. The blade would get occasionally bogged down in tall thick grass. I’d usually have to empty the bin halfway thru. I bought one replacement “battery” unit from Neuton (sadly I recycled the entire old unit).
I ran into the dry cell replacement videos while looking for a better deal... could it really be that easy? Grabbed a torx bit ($3 at the hardware store) and took a look inside the battery case; sure enough it was two big batteries connected with some wiring.
Swapped them out easy as pie, plugged it in overnight, and went to town.
These batteries “match” the output and voltage specs with the original ones, but that’s not the half of it: The power output now punches thru the tallest grass, and better still, packs the grass into the bin so well, I can mow the entire lawn without stopping to empty it. That never happened with the new mower or the replacement battery pack. I haven’t tried to run it all the way down, why bother? I could not be more pleased with these batteries. If they last 4-5 years they’ll get 6 stars!

DizRotus: I purchased four of these to possibly power my Texas Instruments TPA3255EVM class-D chip amplifier. When I decided to use a Mean Well power supply instead, these just sat on the shelf for a year. This summer I installed one in my DIY boombox that uses SURE components: class-D chip amp, Bluetooth receiver and stereo solid state volume control. After sitting on a shelf for more than a year, the battery was at 13.7 volts. I decided to run it dead before fully charging it with an SLA battery trickle charger. After three days (72 hours) of continuous operation, the voltage was still above 10 (the boombox will play until the voltage drops below 9). After two more days of being on but no longer playing music the voltage was down to 5.5, so I finally connected the charger. The next morning it was back to 13.5v. I can’t comment on the batteries performance with a high current load, such as a lawnmower, but it’s amazing in this application.

J. McGaw: This is one of those products which is virtually impossible to rate, at least in the short term. The real measure of quality is how long and how well they work. Visually the batteries are clean and uniform and there are no external manufacturing defects. Mine were bought as replacements in an elderly Cyberpower 1200AVR UPS (Uninterruptible Power Supply) that backs up one my number-crunching computers. The replacement is quite manageable, basically consisting of getting the old battery pack out, disassembling the pack, reassembling with the new batteries into the pack assembly, and re-installing. If one is careful it would be impossible to go wrong. The UPS worked and passed a self-test right after the change so there was some latent charge in the batteries. In a few years I'll be able to say definitively how good they really are but by then I'm sure I'll forget to come back and amend this review.
