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.

These batteries work exactly as expected and have been a perfect replacement for my equipment. They hold charge well and provide consistent performance for ride-on toys and backup use. Installation was simple, and both units arrived well packaged. Overall, very reliable and great value.

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 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.

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.

If you have a Cyberpower 1000 VA UPS, and the battery has died, instead of purchasing a whole new unit, you can replace the battery easily, and save lots of money. This battery is a direct factory replacement battery, as far as voltage, size and connections. Don't know if you have a dead backup battery? Here's how you find out. The easy way is have a piece of hardware (computer) plugged into one of the battery backup sockets, and turned on. Then unplug the backup supply from the wall. If your computer is still on, you battery is fine. If the backup starts beeping right away, it's close to dying If you unplug from the wall, and everything dies when you unplug from the wall...the battery is DEAD. Time to replace.

This review is for the 2-pack replacement battery. These batteries are made in Vietnam. I have a BACKUPS-XS1500 LCD un-interruptible power supply that I have had for a number of years and been through a number of batteries. I learned a long time ago, that APC does not make their own batteries and utilize a variety of battery manufacturers and just put their labels on the batteries charging a premium. Unfortunately, one of my alternate brands is no longer available here and another brand I got ended up being a bad battery and a difficult return process. I decided to try this brand of battery, directly from AMZ, which is less than half the price of APC batteries. This battery looks identical in terms of specifications and initially fit in my UPS. The biggest difference is that I had to use the connecting terminal wire from my old battery as this 2-pack didn’t come with one. I also had to use double sided tape to put them together for my specific APC battery backup. Once I put them together, the battery pack fits in my APC the same as the previous battery. Unlike the previous battery I tried, I did not get a failure alarm with the battery when I first put the battery in the UPC. The batteries were not charged well though initially at 27 percent, so I had to wait for a few hours to get them charged to do the battery test. That charge level does give me some concern about the age of these batteries and whether they are fresh or not. After reaching full charge, I did a self-test and the battery passed. The battery run-time also seemed to be comparable to my previous battery. The biggest concern is longevity with this brand, which I will have to wait and see and update my review. I expect at least three years of battery life, but unlike some brands, this brand only has a one-year warranty as compared to 2-years to others, which gives me some concern about the quality of the battery. I will update my review with any durability issues. So far, it is working as it should in my battery backup. 4 stars

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?
