batt question?

Question

ok i let my car sit from Oct 2006 and i charged the batt up about 4 weeks ago and it is not strong enough to start the car now the batt in it is only 1 year old but im thinking the batt might of froze over winter but not 100% if it did is it ok to try and charge it again?? like if i leave the batt charger on the batt all night.

thanks for your answers

Answer 1

i own a repair shop and that's the best way to charge it,use a slow over night charge on it,this way the cells wont over heat in it and ruin the battery,fast charging one is bad for it,it gets the cells hot,and ruins them,a good over night or what they call a 12 hour charge will be what it needs ,and if its any good at all it will charge back up,it is possible that it could have went bad,but I'm assuming it probably has a good warranty on it,so try slow charging it first,then if that doesn't work ,you may wind up having to replace it,good luck i hope this helps.

Batteries can get to 60 below without freezing. How often do you here of Minnesota shutting down because everybody's batteries froze overnight? Dodgeman is an incompetent idiot. Alternators charge batteries at close to 40 amps when the battery is low. It's the high voltage that cheap chargers get up to that cook them, and low amp chargers are usually the cheapest. Get a good fully automatic charger that shuts off when the battery is charged.
And, pretty much every one of these halfwits who list their certifications and experience whenever they answer a question are phonies.

Answer 3

Sitting four weeks may be long enough to drain just enough power to cause it not to start. Modern cars with all the electronics still have parasitic loads, even when everything's 'off'. The ECU, entertainment system, alarm system, and whatever other computers may be in the car, continue to draw power to maintain memory function. If you can't run it often enough to keep it charged, you should invest in a 'battery maintainer' and keep it plugged in. This will keep the battery at optimum charge all the time while the car is stored, without overcharging it.

Answer 4

Listen to Dodgeman.

Do not listen to bumbles. Batteries do freeze. Bumbles is obviously confusing Hydrosulfuric acid with alcohol, of which I have no doubt he (or she) is familiar.

Answer 5

Batterys dont feeze, due to the electrolyte in them. If the battery is weak and wont start your car them I would try to chagre it and see if it holds a charge, if it does then thats good. If it dosent get a new one.... easy.....

Answer 6

if it froze theres a good chance its shot,take it out and take it to part store and have it tested just to make sure but dont get your hopes up.

Answer 7

if the battery got frozen,its not good on it.you could have a dead cell and not taking charge.
