Rated 5 out of 5 by from 2.1 Amp Battery Excellent, surprised when unboxed it was a Yucell battery, top quality branded battery. Slightly more expensive but when you need one on Sunday and screwfix has got one to sell that's why.

Rated 5 out of 5 by from Easy swap Took longer to get the screwdriver from the garage. Quick swap with old battery. Too early to judge performance but older reviews give it thumbs up. Terminals at both ends has mentioned previously and height includes terminals. Body height is 62mm.

Rated 5 out of 5 by from Alarm battery Fitted in burglar alarm to replace 10 year old one which had given up. After approx 1 year in use without any issues I tried removing mains from alarm to test the replacement battery under load. The battery held the alarm up for over 24hours so pleased with its performance so far

Whats the output?

I want a 12v battery with output current of 6A max
Asked by: Jaxson

I propose to use this battery in my house alarm to replace my old one - It is the same spec as the one I am replacing but it does not say 'rechargeable' on it - I am just checking that its the right one.

Asked by: wardy71
Yes it's rechargeable. If you need a clue then notice that the description says float or cyclic use. Float means can be (permanently) connected to a float (battery) charger to maintain the fully charged state (as would happen in a burglar alarm where the normal mains supply is "healthy"). Cyclic means the battery can be discharged (as would happen if your alarm mains failed and the battery then runs the alarm) then recharged (as in when your alarm mains is restored again).
