12V Battery Replacement

I think I need to replace my 12v battery. In terms of replacement, I assume any 12 v sealed lead-acid battery will work. My current battery is a 4ah, and I was going to replace it with a 5ah.

Any other considerations?

Yep, that’d be what you want. The batteries can be found through hardware stores and online vendors. We sell a 5AH one here.
