CSBHRL1234WF2FR 12 V Battery

I bought this battery to replace the OEM battery in a UPS. In the past I have purchased the "HR" version of this battery, which have performed very well, so wanted to try this, the "HRL" (High Rate Life) version to compare. Since it is new I can not speak to longevity yet, but will update this review if it does not perform up to spec.Also, I purchased this battery from seller "Atlantic Battery Systems" and the battery arrived quickly and with a good charge on it, 12.7v. Overall a very positive purchase experience.

I gave it 5 stars because it arrived when expected and packed well. Also, I am familiar with the HRL Series by CSB. It is rated for a longer life than the HR or the GP and the other brands of batteries of this type. A lot less expensive than the APC replacement part.

Title says it all. I thought this batt was going to be different and unfortunately, it wasn't. It just didn't last and burned out and stopped working after ONLY 14 months (from May 2020 to July 2021). Mind you, my UPS NEVER used the battery backup during that time. It was ALWAYS charged up for the 14 months until the other day it just stopped working. When I called the company a couple of times (since they never returned my call), they told me the bad news. I thought they'd understand and work with me (being such a HUGE company), but NO. They didn't BUYER BEWARE as most people here already wrote their reviews. I usually wait until months or even over a year BEFORE I write something. I would NOT purchase these batts from them and look elsewhere. Your choice though...

Two of these will work in an APC RBC124 battery pack. Needs the original bracket. Be sure to note the correct orientation of the wiring and assembly before replacing.The original batteries in the pack were model HR1234W.

Direct replacement for the old batteries in my APC UPS. At first the APC wasn't happy (saying they were fully charged, but not giving full length of time they would last at the current energy output), but after they charged for 12 hours it has been fine. It has worked properly over 2 small power outages.

UPS just indicted battery failure after 4-5 years from install. They have definitely served their purpose in our Back-UPS RS 1500.

2 of these were used in tandem in apc smart-ups smt750i.After only 3 years, one of the batteries expanded and cracked the casing.

The CSB (Hitachi) HRL series is currently my go-to battery for UPSes.
