how long to i need to charge my car battery with a charger? and for how long to I need to drive it afterwards?

Question

And at what speed etc for it to start again after the next time i stop it?

Answer 1

Overnight should usually charge it Okay.

If your car starts OK, then 15-20 minutes should recharge it.

Go to a place that sells batteries and they will check the performance of your battery, it may be old and requiring replacement. The performance of batteries drops dramatically in cold weather.

Don't just rush out and buy a new battery without confirming that there is something wrong with the OLD battery. There are many other reasons why the battery could be discharging.

Answer 2

Hi

If your battery has been completely flat then it will only be around 75% effective once you have fully recharged it.

A normal battery charger will charge at about 9 a/hr and therefore you would need to leave it for a good few hours before it had a decent charge in it.

Your best bet is a jump start pack which will allow you to start the car immediately. It connects to your battery just like a battery charger but it delivers a good ampage, but you must disconnect it immediately, and remember, the negative lead always comes off first and goes on last!

Finally, once the car is started, drive it for a good quarter of an hour at normal road speeds to finish the charge, or leave it idling for about half an hour.

If it loses its charge again then you need to think about removing it and taking it to an autofactors to have it tested on the premise that it may be faulty.

If you need to charge your battery at all there is something wrong.
If it's dead get a boost, it won't hurt a thing unless the cables are backwards. Let it run for ten minutes, turn it off. It should restart. If not your alternator could be fried. The alternator is what keeps your battery charged while the engine is running.
Have the battery tested, most places will do it for free.
If you live in a cold climate it's best to buy a battery that's made for -degree weather. Most batteries today have a 3 or 5 year warranty, there should be a sticker on it. They range anywhere from $40-$120 thereabouts.
As for charging it, overnight if your not in a hurry, 2-3 hours should start it.

Answer 4

ok overnight is the favorite way of charging a battery, this will only have enough life to crank your car over a few times without it failing to turn it over at all.
PLEASE MAKE SURE THAT YOU REMOVE THE CELL CAPS IF THEY COME OFF OR IT IS BANG NYE BYE BATTERY, CHECK THAT THE ACID LEVEL IS OK IN EACH CELL, YOU MIGHT NEED A TOP WITH DE-IONISED WATER OF WHICH YOU PUT IN ENOUGH TO JUST COVER THE PLATES IN EACH CELL.
if it does start then a half hour drive in the day time so no lights have to be on or the radio should give it enough, you are looking at a constant speed of around 40mph - 50 mph so use a dual carraige way or some where you can do that speed without stop starting.
if you know of some one with a voltmeter once the car is started ask them to check you are getting a good charge from the alternator by putting the voltmeter pins on the battery terminals at the correct polarity if it is reading at around 14.3v - 14.6v then put your lights on to check the charging under load anything above 12 v is good any less its an new alternator and possibly a battery with this damn cold wheather.
good luck

Answer 5

till it rather is a "speedy cost"charger then over-evening is popular to get an outstanding cost. If the battery mild replaced into no longer on whilst the automobile replaced into working then that is not any longer the alternator. If there is any white crud starting to be on the battery terminals this could insulate the battery connections and it could no longer recharge whilst driving the automobile or in case you hook up a charger to it. maximum batteries will final the size of the guaranty era plus some months if pushed around city with some street miles and that they'll final way previous the guaranty era in case you do usually street miles and save the terminals clean (provider like another 3 hundred and sixty 5 days or as quickly as a 300 and sixty 5 days if parked outdoors each and all the time). maximum places that sell batteries will do a loose charging device diagnostic and this assessments the battery, alternator, and starter. good luck!

Answer 6

I don't use my car a lot and often get a low battery, I bought one of those booster starters, only cost around £12, just clip it onto the battery and away you go! Garage told me that you need to run the car for half an hour (without any thing switched on) before it reaches full charge. £12 well spent, just remember to recharge the booster after using a couple of times. It certainly beats getting the jump leads out and looking around for another car to tap into.

Answer 7

Look at the battery lable, for how many amp/hours capacity. If for instance it is a 150a/h battery, then charging @ 15amp charge would take ten hours. Do the math.
A garage can put a load meter on the battery to see if it is still ok.

Answer 8

If you don't get the answer in here properly then I would call a dealership and ask for service department and talk to one of the mechanics there and he or she should have an answer for you. Make sure you call the dealership that sells your car ofcourse. By the way, jumping someones car can actually take a strain on your battery. So don't jump someone else's car or have someone jump yours unless you have absolutely no choice. Good luck.

Answer 9

If you have jumper leads get it going with another car, then take it for a drive 15 mins. If it is winter, you may just be due for a new battery.

Answer 10

any time from 2hours to 12 then take the car for a good 20 to 30 miles run
