My car battery is dead. In terms of weeks, does it matter when I jump the car and recharge the battery?

Answer 1

It doesn't matter. But the battery might not hold the charge if there is a dead cell in it. Get the the whole charging system checked (alternator and belt).

Answer 2

Storage batteries don't hold a charge forever--if they sit for long enough they will lose their charge and need to be recharged. You can recharge yours by getting a jump and keeping the jump connected for 5-10 minutes while revving the good car a little (idling produces very little electricity). THEN start it while it is still connected. THEN you can disconnect the jump and take the car for a good long drive at highway speeds to help recharge the battery completely. Before you jump it, if the battery has top posts, it would be good to disconnect each cable ONE AT A TIME and clean where it touches the battery with a battery terminal double brush, (auto parts store or Walmart, $3.50), then reconnect tightly. It is always good to warm it up for at least a minute before driving it, maybe several minutes the first time after a long sit. Best regards, Mike

Answer 3

I ran my car battery flat 3 times last week. We push started twice and jump started once - on the same day. You might be best to try to recharge as soon as you can.

Answer 4

If the battery is lleft in an uncharged state long enough, the electrolyte(acid) loses it's specific gravity and it won't recharge. In winter the electrolyte could freeze if exposed to cold enough temps, crack the housing to the battery, nuff said.

Answer 5

also, you may want to check your alternator. It may be the problem of your battery dying alot. an alternator is what keeps your system charged once the car is running, if it fails it will cause your electrical system to run off your battery, draining it alot quicker than normal. Some places like AutoZone test the charging system on alternators for free, although you may have to take it off for them to test it.

If your belt is slipping it could also cause your alternator to not charge properly. wiggle the serpentine belt there should be a decent amount of tension there, also chck it for cracks.

Answer 6

Provided the alternator is ok. It should not matter. Make sure the battery connection does not have corrosion on it and the battey is still able to accept a charge.

Answer 7

depending on the batt. yes...if it is a stock battery or not a deep cycle batt. then you need to recharge it quickly or the batt will lose even more voltage..when a NON deep cycle batt loses power you recharge it but it doesnt get fully back to new conditions. example if you recharge the bat now you will lose 15% of its total power, if it happens again or it loses more voltage the batt can lose up to 65% of its capacity, and leave you stuck somewhere

Answer 8

what caused the battery to go dead to begin with ?does it have a dead cell or something shorting it out,is the alternator bad,any and all these factors could have an effect on the question you asked

Answer 9

If you leave a battery dead low for weeks it may never be able to be charged again.You need to keep them fully charged especially in this cold weather.

Answer 10

if battery is frozen and you boost or and or recharge it may be dangerous it can explode
