Perfect Replacement for Razor Electric Motorbike
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.

ExpertPower 12v 9ah Sealed Lead Acid Battery
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.

Perfect Replacement batteries for my CyberPower 1500vac Backup System
I have a CyberPower 1500VAC Battery Backup that began throwing the E02 error. This error is indicative of the current batteries not holding the appropriate voltage. Upon investigating, these batteries appeared to be direct replacement and so I went for it. These arrived exactly as advertized and were, in fact, exact replacements for the ones I removed from my CyberPower. I tested the voltage of each prior to installation and they were both showing about 14v. Knowing the voltage was good, I quickly got them installed and powered up the device. The batteries arrived with an approximate state of charge around 90%. I have been running these for just over a week without any issues. This was a very simple and straightforward fix with a quality replacement at a fair price. I have chosen to rate this product 5 stars. It has met my expectations for the price and I would completely recommend. Although I haven't had them for very long, I have monitoried them every day and they are holding the charge as expected. Due to my immediate need for the replacement batteries, I didn't spend much time reading previous reviews, but these are definitely worth reviewing. They were exactly what I was looking for and working exactly as advertised. Criteria for Stars: 1 - Total rip off, doesn't perform basic advertised functions or not product advertised. I would likely RETURN and would NEVER recommend. 2 - Not worth the money. Performs some of the basic advertised functions, but likely not all, and ultimately was deemed as not providing enough value for the money spent. I would not buy again, and would likely not recommend unless the buyer had a very specific use case. 3 - It performs the basic functions as advertised, and has some usefulness at the price point, but doesn't work for all of the reasons I purchased. I would likely not buy again, and would only recommend if buyer understood usefulness limitations. 4 - It performs most all of the features I purchased it for, but has limitations. I would likely buy again and would recommend. 5 - Completely as advertised and likely exceeded expectations. Is if high quality and well shipped. I would totally buy again and recommend.

Decent batteries with OEM-level performance (see details). Recommended
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

Reliable, Well-Built Batteries — Perfect Fit and Great Performance
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.

Reliable Replacement Battery for APC BX 1500G – Solved F02 Error Instantly
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.

Didn't even make it 8 months. Useless warranty. DON'T BE SUCKERED BY LOW PRICE.
ExpertPower's replacement for the CP1500PFCLCD battery backup is one of the biggest frauds on Amazon. I purchased a set in April 2025, and installed it in May. I tested it thoroughly, charged the battery fully, ran it down mostly, charged it back up, then I hooked it up to a small server where it suggested about a 100 minute battery life - it's there primarily to allow the server time enough to safely shut down after a few minutes. Come today in January 2026, the power went out and my other UPSes with 4 or 5 year old batteries cranked away dutifully - but when I went to check the one with the ExpertPower batteries within 2 or 3 minutes, it had immediately crash shut down, and crashed again when trying to reboot. I checked it again with no load at all and the battery showed less than 5 minutes of power. This isn't a backup; it's a bad battery that should have never been sold. The warranty on this requires you to pay for returns, which for an item this heavy is going to be close to the cost of a new one. Even if you're playing the lottery on a cheap brand (and yes, the CyberPowers are wildly overpriced), this ain't the one to buy. AVOID EXPERTPOWER.

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.
