Hi Guys,
Thanks for the replies - reason I asked was that battery light came up for a couple of seconds last night, while I had blower / Stereo and lights on - and thought it may be overpowering the battery - I've monitored it today and the light hasnt come on once. Was surprised how small battery was, but looked well greased on terminals and generally good nick. Panic over nothing but will replace with heavier duty one when it does pack in.
Thanks again - appreciate it.
Si
