car battery question

[lyle ericksson]

if u buy a new battery and put in in your car but not drive ur car is there a chance the battery will not be able to start the car when u finally do power it up? after how many days would this occur ? this happened to me and i want to know if it means i have a power leak or if its normal since the car was not driven for maybe 60 days

It’s possible the battery could drain enough that it wouldn’t have enough power to start the vehicle after 60 days. That’s a long time. If you are going to have a car sit that long you should connect it to a battery maintainer. ETCG has a good video on checking for parasitic draw. That will tell you if your car is drawing more power than it should while it’s sitting.

I personally experimented with that for a long time many years ago when i was a field tech and have to leave cars in long term airport lots. More than two weeks will kill a car battery unless a miracle happens. These days they sell little solar squares that you can just throw at your dash (if you pick a spot where there is sun) that works as a trickle charger when connected to a lighter outlet. Otherwise, carry a fully charged lithium battery pack (10-20 Ah’a) with a USB to about 12.5 volt converter to feed the car battery with a few milliamp’s continuously and keep the car topped off until you come back to use it again
