UPLUS LP12-9.0 12V 9Ah Rechargeable AGM Battery replace for RBC17 RB1290 | with F2/F1 Terminals,SLA replacement for APC UPS, Cyberpower Backup System, Kids Ride on Car

Used it to replace my Genie garage door opener backup battery. Perfect fit and true to the description. Much less expensive than a brand name battery and works well.

This works well and easy to replace.

The battery arrived exactly as described. It was charged and fit perfectly. It was ordered to replace a dead battery in my firman generator (Firman Model: WH02942). The model number isn't my exact model but close enough. I did forget about the battery posts adapters until I noticed them in a small package...I added the F1/F2 adapters. All was well and the battery performed as expected.

I've been using an RL800 to cut our grass since 2004. The only maintenance is buying new blades (getting hard to find), sharpening old blades (using a Sharpal), and replacing the batteries. The last two sets of 12v 18ah batteries I've bought through Amazon have each lasted 5 years, almost to the day, but they have to be Deep Cycle batteries.Of course, the description for these "UPLUS LP12-20 12V 20Ah Rechargeable AGM Batteries" says they are Deep Cycle, but I can't find that printed anywhere on the battery itself. I also decided to go up to 12v 20ah for this set since they're the same size. The important thing about these size batteries is the actual WEIGHT when received.Some companies take shortcuts with inferior components or even less material inside the casings than their specifications list. Then the batteries don't last as long as they should. I experienced this once before. Unfortunately, there's no foolproof way to know how long these batteries will last right out of the box.But I do weigh them as soon as I open the box. If the weight of the battery is at least what the spec says, then I'm happy (provided it works well of course). These spec at 12.46 lbs, or 12 lbs 7.36 oz. In my photos, you can see one weighed 12 lbs 10 oz and the other 12 lbs 12.7 oz, both weighing a little more than spec out of the box. That's a good thing.The first couple of times I cut my yard with these batteries, they only went down to 1/2 on the handheld controller battery gauge. After they cool down, I hook them up to the Robomow charger that keeps them topped off with the trickle charge. That's important with this type of battery.So I'm pleased with these UPLUS batteries so far. They are priced right too. Hopefully, I can get 5 years out of this set for the $80 paid. The longer warranty than normal makes me believe I will.

Installation was easy and the battery fit the compartment like a glove. Same size as the OEM battery. The beeping has also stopped.

Perfect replacement

Arrived right on time. Easy install instructions. Finally no annoying beeping in garage!

Excellent garage door battery replacement. Quick shipment. Would order again!
