Question: What is the warranty on these batteries if any?
Document: Ordered these batteries for a UPC on our business server. Batteries had good reviews and I will concur that they work.
Direct replacement for a UPS that was indicating failing batteries.Plugged in the supplied battery pack in place of the original ones and all worked perfectly.
This is the 3rd replacement battery for my main UPS system. I been running my APC UPS continuously since 1998, so 4 batteries (including original) over 15 years isn't bad.
The batteries look great, but I can't use them, because the old batteries appear to be glued into my APC BR1500LCD UPS!Make sure that you can remove the old batteries before purchasing replacement batteries!! !
These batteries are NOT OEM APCRBC109 replacements, the APCRBC109 are 9Ah batteries, these are 7.2Ah batteries. They will work, but you will not receive as long a runtime under load as official 9Ah APCRBC109 batteries. Sources:[...] "APCRBC109"
This unit is an exact replacement for the factory batteries at a fraction of the cost. You will find this to be a suitable replacement..... Just make certain that you receive the 109. I was originally sent the smaller powered un it - same size but less backup capability.
Third-party replacement batteries for APC 1500 UPS. We were having difficulties finding replacements for our APC BR1500LCD and we are quite pleased with the performance of these extra batteries thus far. (Performed failover testing, and they worked great).
I have an older APC RS 1500. This battery replacement worked very well. Installation was quick and simple, no gimmicks or modifications required. This battery pack is a nice economical alternative to overpriced OEM APC batteries for older UPS devices like mine.
Came with 80+% charge. Installed them yesterday afternoon and today at noon we already had our 1st power outage on the new batteries, only about a 15 minute outage, but the UPS kept the network up flawlessly with over 2 hours to spare. They fit mechanically and electrically, what can I say?
I thought I'd try these replacement batteries for our aging units, rather than buy entire (expensive) units. I've tried them in two of the APC UPS units we have and they've performed beautifully. I'm going to go ahead and get some more to have on hand for our other APC UPSes.
Answer: The battery is warranted against defects for two years to the original purchaser.
