ExpertPower ® 12v 9ah Sealed Lead Acid Battery with F2 Terminals (.250") / 4 Pack

I’ve ordered these in the past and they are a great value when bought in a bundle of four.

The poor neglected UPS just sits there until needed. Years pass and then the batteries finally die. Just replace the batteries for a third the cost of a new UPS. They usually last about five years, and this is the second time I am replacing them. I have done this with four UPS systems so far and never had any issues. Just take your time as they are heavy.

I bought this 4-pack batteries to use in my two UPS - each uses two batteries. This was the first time I bought this brand. For the first several days, they worked fine and I threw away all the packing materials. Then one UPS unit failed. If I moved the other two batteries into this failed UPS, it would work fine. So I concluded it was battery problem and contacted the seller.The seller was responsive and asked me to ascertain that both batteries in the failed UPS were bad. It took me some time to swap in and out individual batteries to make sure that both were bad. Then the seller offered me to replace them - but I was asked to go through a lengthy RMA process and pack the bad batteries following a set of complicated instructions (for acid based batteries). It also warned that if the batteries are not packaged as instructed, the seller would refuse to accept the return shipment - I do not know what would happen if it is refused.In any case, I decided that it is not worth my time and effort to go through the RMA process and to pack the batteries as specified (since I have thrown away the original packing materials). I will buy two batteries of another brand that offers Prime.In conclusion, I would not recommend this brand and this seller. Two out four batteries failed within 10 days does not indicate good quality and the seller's replacement process is very difficult to follow. If you choose to give it a try, keep the packing materials around just in case.

I'm rating this with a bit of trepidation. In Amazonspeak, 4 stars means "I like it." Problem is, these are batteries and batteries really cannot be properly rated until "x" amount of usage. So, what I "like" about this product is 1) the price was, in my opinion, excellent (will revise this if early failures occur) and 2) delivery was fast with each battery shipped in its own box that was then inserted into a USPS Priority Mail box. The batteries were exactly what I expected and arrived in perfect (it appears) condition. I don't have any way to test the batteries for how full the charge was on arrival, but each battery tested for 12V on my voltmeter. To be safe, I inserted the batteries into each of my UPS devices and allowed them to further charge for several hours before placing any load on them. If any signs of battery failure appears within one year, I will revise this review.

Bought the 4 pack to replace the batteries in two Cyberpower CP1500PFCLCD UPS units. I was able to pull out the old batteries, then moving the wiring over to the new batteries. I added a little packing tape to keep everything together, then I was able to slide the two new batteries back inside the UPS. I'm getting an excellent run time on these new batteries. Also, the batteries I received were well packaged and arrived priority via USPS. I will be ordering more of these batteries in the future. Thanks ExpertPower!

Factory Power Wheels batteries are very expensive. These replacements do just as well if not better and are way cheaper. You get four for price of one factory battery. So far so good. Hope they last a while.

I bought these for my 2 CyberPower 1500 battery BackUPS. Each takes 2 batteries, so the 4 pack was perfect. I'm guessing it's a fairly standard size, they fit perfectly. Once installed my UPS went to 100% available battery power. I can't speak to longevity as I just installed them. After I have a power failure I'll update this review if for any reason they don't live up to my 5 Star rating.Update: The batteries lasted me about 2.5 years before I had to replace them. I replaced them with these same batteries.

Exact fit for APC Backups 1300, Geek Squad 1500, Cyber Security 1500. Easy installation of existing wiring (snug fit connections). My previous purchase of these batteries lasted almost 4 years which is why I repurchased these again! Fast shipping that beat the estimated delivery date by a couple of days!
