APC UPS Battery Replacement, RBC10, for APC Back-UPS Model BF350, BF280C

I looked up the model of battery that my UPS needed on APC's website. They stated it was BF250, this item, so I ordered it here at Amazon. Unfortunately, APC believes BF250 is known as RBC33, but the listing for BF250 on Amazon.com is RBC10, which is a slightly different size, has terminals in a different place, and is only one actual battery, not the pair that is RBC33. So, make sure this is really what you want.

ＢＦ２５０Ｊは小型軽量のＡＰＣ社のバッテリーです。コンピュター以外の周辺機器等のバックアップ用に向いています。
