Fresh, Genuine Battery
Like other reviewers have mentioned, this is a great battery for UPS duty. I replaced my 5yr old APC battery with this unit. It arrived in good protective packaging and with acceptable open voltage. I love that Atbatt.com can offer batteries with legitimate manufacture dates. A lot of batteries I have purchased from other vendors sit around for years without topping charges before they get to your door; this is a non-issue when you are receiving a battery you know was manufactured <6 months ago!

The battery seemed to work correctly in my UPS at first but then my OS reported that the charge level was slowly falling all the way to 9% over the course of a month. AtBatt customer service was great and sent me return authorization immediately. However, since I was so confident in the quality of this battery I decided to perform some independent charge/discharge tests using my advanced hobby charger. It turns out the battery was fine; the charging component of my old UPS was to blame.

The short version: This battery is a great buy! Do not hesitate! Review by Dan / (Posted on 11/10/2015)
OEM Replacement for APC
I purchased these because this was the original battery in my APC unit when I peeled off their label. I was very happy with my original unit. I think original batteries were still good, but swapped out with new fresh batteries per owner manual recommendation.

The CSB batteries arrived promptly from atbatt.com and was packaged professionally. Happy customer and will recommend to others. Review by Brandon Riggs / (Posted on 11/10/2015)

Exactly what I wanted
I bought a battery from Amazon thinking I was getting a CSB battery, but it was a cheap knockoff battery that looked used. I complained to Amazon that this was false advertising. Amazon gave me a full refund and told me that they will discuss the matter with marketplace seller.

I was confirmed by atbatt that it was a genuine CSB battery brand. I ordered it and to my delight it was a CSB battery. With a 1 month old date code. I will definitely buy from AtBatt again. Review by What you see is what you get / (Posted on 11/10/2015)
