Replacement battery for BE425M

[bariumbitmap]

What is the correct replacement battery for the APC Back-UPS BE425M? There's nothing about it in the manual and the replacement battery finder page just says "Nothing found".

You can take the battery out to confirm but it appears this unit takes a small form factor 12 VDC 4.5 AH cell like this:

It should be noted this battery also comes in a 5 AH capacity which should be considered also. As it will provide more operational runtime during a grid down event (black out). 👍

Lastly, the OEM cells are CSB so try to purchase the same. As they are extremely high quality and offer the best service life.

If the information is on point and resolves the question please mark this as solved.
