Just been for a drive, with lights used mainly full beam for 2 hours, Kenlow switching in every now and again, heater fan. After 2 hour dirve lights went dull. I stopped on drive, switched off and now battery is flat.

I know I am getting some juice from altenator, but is there anyway of testing if it is enought to sustain drain from above I.e. is it cream crackered?

Oh battery is 2 weeks old! and was fully chargered before I set off...

Thanks

Click to expand...

there'll be a code stamped/printed on it - 16/17/17ACR or something along those lines

charge the battery over night from the mains - you'll probably just have drawn too much from it having so much on, or ya battery is dying - as long as there's over 14 ish volts across the battery when the engine is running the alt should be fine

If you think your battery is shot, stick a multimeter on it and try to start it, if it drops below 9 volts then you can be sure your battery is shot, remember that frost will kill a flat battery but a charged battery is more resiliant
