ExpertPower EXP1290 (2 Pack) - 12V 9AH SLA AGM Rechargeable 12V Battery for Ride on Toys, Backup UPS Battery Replacement, 12 Volt Batteries for Alarm, Electric Bike, F2 Terminals (.250")

These ExpertPower 12V 9Ah batteries worked excellently as replacements for a Razor electric motorbike. The F2 terminals matched the original battery connectors perfectly, making installation straightforward. Performance: After replacement, the motorbike runs exactly as it did with the original batteries. Run time appears comparable to when the bike was new, and the batteries hold their charge well between uses. Installation: The dimensions fit the battery compartment without modification. The terminal orientation was correct for direct connection to the existing wiring harness. Total replacement time was about 15 minutes. Value: At this price point, these batteries offer solid performance for toy vehicle applications. The sealed lead acid design means no maintenance required. Recommendation: Highly recommended for Razor motorbike battery replacements or similar 12V toy vehicle applications. The F2 terminals are standard for most Razor products, so compatibility should be good across their product line. Tip: When replacing both batteries, mark the positive terminals clearly during removal to ensure correct installation of the new batteries.

The ExpertPower 12V 9Ah Sealed Lead Acid Battery (2 Pack) is a great value. Both batteries arrived fully charged and have held power really well. Easy to install with the F2 terminals, and they’ve been reliable in my application so far. Solid build and consistent performance—would definitely buy again.

I bought this 2-pack of ExpertPower 12V 9Ah SLA AGM batteries as replacements for my home UPS system, and they've performed flawlessly so far. The fit was exact, and the F2 fast-on terminals made installation quick and hassle-free — literally plug and play. Each battery arrived well-packaged, fully charged, and in perfect condition. I appreciate the AGM design — no spills, no maintenance, and very clean to handle. The non-conductive ABS casing feels durable and solid, and the batteries hold their charge as expected, even under moderate load. I also tested one in a gate opener system, and it’s running like new again. These are definitely versatile and dependable for a range of 12V applications — from UPS backup to scooters or alarm systems. For the price and quality, this is a great value 2-pack, and I’d absolutely buy again when it’s time to replace more batteries.

My Cyberpower 1500PFCLCD had been great, but eventually the UPS and AVR functionality died. I think the SLAs that came with the UPS lasted about 3 years. I have no idea if CyberPower has an OEM battery option, but batteries are batteries, so there's no reason to pay OEM prices. Though they took a couple weeks to arrive, the ExpertPower 12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250")/2 Pack showed up at my doorstep undamaged and intact. The packaging wasn't extremely protective, but SLAs aren't exactly delicate, either. The 1500PFCLCD comes apart with two small screws. The faceplate slides off, revealing a wire harness and the battery pack. Once you disconnect the wire harness, you can slide out the pack. The "pack" just consists of two batteries with a plastic tray in-between them. The plate has wires that put the pack into series, so it's just a matter of sliding 4 spade connectors onto the F2 battery terminals. You can tape the pack together, but it's not necessary if you hold it together when you slide it back into the UPS. Once you've done that, you just re-attach the wire harness. Really, that's it. My batteries arrived about 90% charged. Nice. I plugged everything in, got everything started, and yanked power. No issues with the UPS at ~85% load. Estimated runtime was close to what I'd calculated for 216 Wh, so the batteries look like they are the right spec. At about $40, the price is good... the only gripe was that the shipping, while advertised as Prime with ~ 1 week delivery, was about double that. Recommended

I recently purchased this battery (sold by Amazon, but from this brand) to replace the one in my APC Back-UPS BX 1500G. It worked perfectly! I did have to reuse the harness from my old battery, but once I put everything together, it fit and functioned without any issues. When I removed the old battery, I noticed that one of the batteries was bulging with one side slit open. Luckily, it didn’t leak and cause a bigger problem. This battery was originally replaced in 2018, so if your battery is old, I highly recommend replacing it before you run into any issues. Before replacing the battery, my UPS kept alarming in the middle of the night with an F02 error. As soon as I installed this new battery, the error disappeared completely. The unit is now running smoothly and quietly with no problems. Overall, I’m very satisfied with this purchase. If you’re looking for a reliable replacement for your APC BX 1500G, this battery does the job perfectly.

He’s been installed now for several months and a little electric jeep for my grandkids. No issues with them at all. They hold charge without any problems.

Great battery, good price.

Las baterías llegaron en el tiempo estimado, bien empacadas y funcionan bien.

It's been in my UPS for about a year without trouble. So far, so good. I've read some people complaining about the connectors being too small, but i didn't have any problems making my connections (of course, you have to make sure you don't attach your cable connectors upside-down).

No son de la capacidad original, pero funcionan perfecto, duran probablemente 30-40% menos, pero en mi caso eso significa tener prendidos un par de dispositivos no críticos (TV) por un par de horas si se llega a ir la electricidad por mucho tiempo... por ejemplo terminar de ver una película, cosas así.

They're batteries. I plugged them in. They work. They're black with square corners. What more do you want me to say?
