Rated 5 out of 5 by from Good No Nonsense Battery Required a 12V 3.0Ah battery for a power bank that I was renovating and this met the requirements. What I got was a 12V 3.2Ah battery from premium battery brand Yuasa which was a bonus as I had expected a generic non branded battery. Very pleased with my purchase.

Fully charged out of the box and exact size as stated in description.This was very welcome as I needed it to silence my house alarm.

Charger?

Does Screwfix sell an "appropriate charger" for these batteries?
Asked by: CPSciren
Hello, We don't sell a matching charger to go with this, but it can be charged using a 12V battery charger (with crocodile clips). Chargers that should work include 4880R, 8312R, 360FY, 37258, 5539R, 2723R. Thanks for using Q&A. [DG]

Can this battery be used in a caravan, (12v rechargeable)

If not what is your cheapest one
Asked by: MikeDack84
Hello, Thank you for using Q&A. To clarify, this is not a leisure battery which are commonly used in caravans, camper vans etc. A typical example of where this would be used is to power a burglar alarm while a house is empty and the electricity is turned off. Hope that helps. MH
