I have a car (not my CR-V) which isn't used very often, lucky to be once a fortnight if that and sometimes the trips are only quite short.
Today after about 3 weeks of non-use, I thought I should start up the car to run some charge thru the battery for fear of it going flat if I didn't start it up. I noticed it turned over somewhat slowly this time...
My question is - will starting a low-use car up and letting it idle for a period of time (say 15 mins, maybe 30 mins) actually charge the battery and do it any good? Or will it be better to drive it around the block?
I don't have a plug in battery charger to trickle-charge it - perhaps if the above isn't an efficient way of doing it then I might have to invest in one.
