M. Ramthun: The batteries I received had a internal resistance of 22.81 Ohms. The one it replaced was 37.61 Ohms.
My last UPS, new, the batteries were at 17.23 Ohms.
I'm not sure why these have so much more internal resistance compared to the ones that come with the UPS.
In theory that initial internal resistance number does matter as long as it stays the same. We'll find out in a year when I check the batteries.

V: This ExpertPower 12v 9ah Lead Acid Battery is a great replacement part for anyone with a toy car or Ups Battery back up. For the battery to work with a Fisher Price Toy Car you would have to buy a adapter to connect it to the cable in the toy car for it to work you would also need the adapter to charge the battery. Regarding a Ups battery back up, you would not need an adapter for it to work on it.

P. Griffin: I put a pair of these batteries into an APC UPS power supply, which has kept our internet up and running during a couple of our fierce storms here in the PNW. So far, so good. We've had the power go out twice and both times the unit has kicked in and kept us online till the power came back up again.
Longevity? I have no idea since it's been only a few months, so only time will tell. I also don't know how long the charge will last - I looked for the best trade-off between amp hours and price and these batteries seemed to be a good choice.
These were easy to re-fit into the APC system, being the correct dimensions as well as having the same connection type.
I'm pleased so far, but will report back if there's any need to in the future. Fingers crossed.

Chris Cline: 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...

Tarzan's Monkey: 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).

F: It is a battery, and it seems to be doing its job. It seems that pricing as listed included all taxes and shipping.

Barry: The price was right. It works and shipping was free. I will not know how long it last compared to name brand, but it seems any that I have used only last about 3 years. Why pay more!

Henry: Avoids buying a new UPS unit, just replace the batteries. Make sure you keep the connectors and make sure they are clean. Easy to do.

The batteries arrived in good condition, charged and appear to work fine when I got them wired up into the UPS harness. I've just started using them so can't speak to long term performance.
Would definitely choose this company again.
