[12 VDC] This is a factory replacement part. It was in stock, shipped quickly, and at a reasonable price. Will definitely come back for these batteries.

[12.775 lb] Exact replacement. Very pleased

[12 VDC] The CyberPower battery was the exact replacement for my 5 year old battery. Works as expected. B&H shipped immediately and I receive it one day earlier than expected.

[Lead-Acid] Popped in the replacement battery for my CyberPower 750VA AVR and the unit was functional again. The UPS wouldn't stay on with the old battery so it was time for replacement.

[12 VDC] I have 12 CyberPower UPS units (3 - CP1000PFCLCD, 3 - CP1500PFCLCD and 6 - CP600LCD) that I replace batteries in every 3 years. The OEM batteries have always provided the best reliability in terms of battery life and providing the longest run times. B&H prices are quite competitive and the PayBoo card saves me over 8%. So now I should be set for another 3 years.

[12.775 lb] This replacement battery fits great. The instruction manual for my Cyberpower AVRG900U unit said that the battery replacement should be Cyberpower RB1290a, which is very difficult to find. After doing some research, I saw that the RB1290 should fit. I purchased the battery, and I gave it a try. I was very happy to see that replacing the old battery was easy. After I charged the new battery for the required amount of time, I tested it, and everything is fine. I am very happy with my purchase.

[12.775 lb] Old battery quit working, to the point of not even allowing the UPS to turn on anymore. New battery working like a champ, great price for B&H, fast shipping, packed well. All I can ask for!

[12.775 lb] Was the exact product I needed. I was impressed with the packing job. The battery was packed just perfect. Great price and OEM battery.

[Lead-Acid] Working well.

[12.775 lb] My last battery lasted 10 yrs.
This batty is just as great.
