thanks for that!!! i,ll get the right one then.Hi,
This has been covered several times - a quick Forum Search should bring up many threads - but in essence:
A "normal" or "starting" battery - as fitted to your car - is designed to release hundreds of amps over quite short periods of times.
A "leisure" battery - as used in a caravan - is designed to release a few tens of amps over very long periods of time - like the task of running a radio, a few lights, and a water pump.
How they do each job is primarily down to the design of the lead plates internal to the battery - thin versus thick, many versus one. So a normal battery has lots of thin plates which means high currents for short periods, and a few thick plates means a leisure battery.
Don't get the wrong one, they are very different in capabilities.
