Product Description

A Battery Worth Trusting When Backup Power Matters

Tired of searching everywhere for a battery that fits your CyberPower or Leoch CPS3.6-12 backup unit, only to come up empty? The SHR3.6-12 is built to the same 12V, 3.6Ah spec as the original, so it drops right in without modification.

This AGM battery holds its charge well between uses and handles high-rate discharge, which matters when your alarm, medical device, or UPS needs power the moment the grid goes down. It's also a popular pick for small engine starts, like Honda push mowers, where OEM batteries are often discontinued.

Grab your exact replacement today and get your equipment back to full strength.

Frequently Asked Questions

Will this battery fit my CyberPower CP350 or CP425 backup unit?

A: Yes. The SHR3.6-12 is the standard internal battery for CyberPower's 350VA to 425VA Standby Series units, including the CP350, CP425G3, and CP425SLG. If your model isn't listed, compare the label on your old battery to confirm the voltage, amp-hour rating, and terminal size match.

Is this the same battery as the BP3.6-12?

A: No. The BP3.6-12 is a different battery series with its own cycle-life rating, and it is not a direct swap for the SHR3.6-12. If your device originally shipped with a BP3.6-12, stick with that series for the correct fit.

My old battery has one small terminal and one large terminal. Will this still work?

A: Yes. Some devices, like certain push mowers, use one F1 and one F2 terminal. This battery ships with two F2-to-F1 adapters, so you can match your original setup with no extra parts to buy.

Is this compatible with the Leoch CPS3.6-12(12V 2.9Ah) or CyberPower CPS3.6-12(12V2.9AH)?

A: Yes. Despite the different amp-hour label, these are physically and electrically interchangeable with the standard CPS3.6-12, and the SHR3.6-12 is the correct replacement for both variants.

How do I install this battery myself?

A: Most devices just need the old battery unclipped and the new one connected with the same polarity, red to red and black to black. Power down and unplug the device first, and double-check polarity before connecting to avoid a short.

Needed a battery for a Honda push mower with key start. OEM battery no longer available. This battery was identical and fits and works great. Couldn’t find it anywhere but Battery Mart. Ordering and shipping was a breeze. Very pleased with purchase.

Battery fit just fine in my push mower. I had to cut the contact on the negative side to make it fit on the mower contact.
