Battery Drain and Intellistart

Recommended Posts

i have had mine on car for 3+ years and has been ok. but i have had a new battery on. also had a new battery on astra too.

 

i always used remote start. the battery in the alarm fob tend to go pretty quick but they only £1 each and carry a few spares along with a few rear bulbs that cost 50p each :)

 

i have been having a bit of trouble with astra. turns out its fanbelt slipping and brand new battery was not holding charge. got new fanbelt £3.30 to fit.

 

always spend spend spend with cars :)

every engine start takes 6-10 miles to replenish the battery,so short trips slowly reduce battery capacity,when temp drops battery capacity also drops, plus cold engine oil(thicker) puts more load on starter - hence winter battery probs-best slow charge 1-2 amperes for 48 hrs at beginning of winter.its hard to find the old fashioned chargers with low current,usually the made in china 5/7/10 amp halfrauds type which have very poor regulation on them and can buckle the lead plates in battery or cause deposits in battery case.

ive got a couple of old chargers that i use,got them at an autojumble for £3 each :eek: should last another 30 years:)
