NPP HR1234W 12V 9Ah AGM Battery - 204Watts 34Watts/Cell F2 Terminals Sealed Lead Acid Rechargeable UPS Batteries Replacement for Back-UPS Alarm Emergency (F2 2Pcs)

Perfect fit in an APC UPS (transferred the small plastic shield from the old battery to the new battery). Ran a full load test, battery lasted 27 minutes. This is longer than the original OEM battery. Replaced a HR1234W battery in a Cyber Power CP850AVRLCD. It was a perfect fit, and the exact match specifications to the battery that was in the Cyber Power.

Moral to the story is, you get what you pay for. Purchased as "new" as a cheaper alternative, but both appeared not to be quite so new upon receipt. Didn't say anything about it at the time because they were charged and kept a charge. Terminals appeared to have been used previously with minor gouging and one was bent and the other discolored. That said, I did NOT use these batteries in the UPS which needed replacements because I wasn't sure I could trust them, so I used them for other less critical purposes. Now a little over a year later (just outside the warranty period), after putting this one back on the Battery Tender to top off, I come back to find clear liquid (assume it's acid) leaking out of the top of the battery next to the positive terminal. Glad I didn't use these in the UPS, that would have made a mess.Bottom line -- look around for other options.

Bought to replace failing battery in UPS. Perfect fit and working as well if not better than original battery. Arrived on time and as described. Would buy again if needed

One of the two batteries had a broken top plate, that exposed the internal parts. In other words, it was dangerous. I am sending it back, but be warned if this happens to you, you have to pay the postage! That is very expensive for this kind of item.
