Genuine UPS Replacement Battery APCRBC133 for UPS Model SMT1500RM2U | Genuine APC replacement battery for rackmount Smart-UPS SMT1500RM2UC, SMT1500RM2UNC. Restores UPS runtime. 2-year warranty.

I had a rack mount APC UPS which was about 3 years old. The battery died on me. I bought this as a replacement, and it worked perfectly. The UPS does weekly self tests and they all pass with this battery.

Fit perfectly and very easy to install. I'd buy it again and recommend it. Watch model numbers carefully and you can't go wrong. I watched a YouTube on how to install and that made it even easier.

Came well packaged and was an exact replacement.

Just like your car it’s better to replace UPS batteries before there is a problem. I missed my window on one of my servers and a power outage took it down hard. Not a good thing for a MS SQL sever. Lesson learned, 3 year replacement cycle now

Unit was installed and caused a battery error on UPS. Discovered that several cables were disconnected. To make matters worse, my tech was using his phone as a flashlight and one of the batteries fell out and cracked his screen ($200 repair). Really kind of pissed that the QC of this product was non-existent. Will NOT be using this supplier in the future.

Unit comes with a label to recycle the old tray & batteries. Unit slid right in. worked perfectly.

Perfect replacement for our CyberPower UPS. Everything was wonderful.

Excellent replacement for the UnIt. Don’t have to power down to replace. Has already been tested during a recent windstorm.

Der Verkäufer hat super-schnell (und günstig) geliefert, die Kommunikation vorab war sehr kompetent.Da noch die Original-Akkus verbaut waren, war der Ausbau anstrengend (die sind mit superstarken doppelseitigen Klebebändern im Käfig befestigt), der Einbau war sehr schnell erledigt (es gibt hier auf youtube Videos).Die Leistung der Akkus passt, ein entsprechender Test der USV war unauffällig. Alles perfekt!

Battery was delivered fine but seems to have been hanging around for ~10months. Battery performed poorly with little benefit over my 6 year old battery. Currently waiting for a reply from APC support but if they are not willing to address this I will return to amazon.UPDATE: APC support were excellent and replaced the battery. New battery performed as expected.

My customer asked me to buy this as UPS, but in reality they are battery packs. So double check before ordering.Ths saler is nice and quick, so I gave a five stars.
