I purchased two of these for my Friendly Robotics RL800 mower and was disappointed with their performance. While initial run time with these batteries was nearly three hours, within a month that time had dropped to less than 10 minutes.
Friendly Robotics thought the mower was working correctly and that the problem was these UPGs were not up to the task. I bought B.B. Batteries EB20-12X which have been working fine and have also used the Werker WKA12-18NBs. UPG UB12180 Sealed Lead Acid Batteries
I purchased these rechargable batteries for my Homelite lawnmower. I'm just a gal with a few basic tools, but I was able to get the old batteries switched out without any problems. I did one at a time so there wouldn't be too many wires to mix up. This was the best price+shipping deal I could find and the company was very prompt in sending them.
After 4 years the batteries on my mower died. I ordered 2 of these and they work great. The only thing I had to do was drill the hole just a bit bigger so the bolt would fit through. I'm pleased with the purchase.
I ordered this battery for my brother-in-law. It is exactly what he was looking for, and we were very satisfied with the quality of the battery, the dimensions were listed correctly, and the delivery was in a very timely manner.
We bought two of these batteries for our Black and Decker cordless electric mower. The last set from the same manufacturer lasted for over 3 years (longer than expected). This order through Amazon was actually less expensive and, as usual, arrived promptly as scheduled and in good condition. Seems pricing for these batteries are all over the map for what is basically a generic product. Amazon's price was lowest.
I ordered this to fit my chipper, the model# was the same as my chipper battery. It came right on time, all charged up, it fit fine and started my chipper up fine. I needed a new battery so I could sell my chipper, it sold to the first person who looked at it, the battery fired it right up. So I can't comment on how long it lasts, also it is made in china so I gave it 4 stars, I would give it 5 stars for the low price and fast service.
This is the exact driver battery replacement for a Walmart instant power Jump start device of mine that would have had to be thrown out because the original battery inside was 6 yrs old. Since the jump pack costs $75 new and this battery is only $30 and works fine, this was a real good deal.'
