Review: Genuine battery is factory fresh and got me back up and running! - After all the spotty reviews I was a bit hesitant to order this battery from desertcart, but decided to anyway and hoped for the best. I was pleasantly surprised that what I received seemed to be pretty recently manufactured in that the measured voltage right out of the box was ~12.8V. I'm not really sure how to read the date code (if there is any on the battery), but if I am reading it correctly, it seems to suggest that it was manufactured around 09/2023 and my purchase date is 04/2024, so roughly half a year, which is not bad at all. For those who are curious like me, the actual brand of the battery is a "Ritar" brand, and made in Vietnam. From a quick google search it seems to be a well known and trusted brand. Install is straight forward and seems to have gotten my old CyberPower UPS back up and running.
Review: easy replacement battery for Cyber Power backup - I ordered the alternate version of the replacement battery for my CP850 (it is typically recommended for the 1000) but notes said that it would fit our unit. It went right in and I had no problems. Charged on receipt and went right throughs elf test with no issues. Easy replacement. The only thing I made sure to do was pull the removal tab off the old battery so this one will be easy to pull out for replacement some day. It might be a bit of a chore to pull it from the unit without that tab.
