Hisense TV, remote keeps using up my batteries, only last a week or two.

run the fault codes first to see if there are any codes, next is to use the scanner to reset the ECM program
Lastly is to check the wiring circuit to ensure that you have not by-passed a control that stops the battery from going flat.
Lastly have a load test done on the battery because the gauge shows full voltage , batteries can fail under a load such as starting.

it sounds like u need to re syncronise ur remote with the car.....after changing batteries.....merc dealership shud help

I think you ansered your own ?
if you have auto zone parts house you could take it there and have a charging system check done free of charge
some outher parts stores offer the same

I replaced the battery in a VW key fob with an exact match of the dead battery I found in it. The fob worked again but the new battery lasted only 1 day. I checked the manual and discovered that the wrong battery had been installed by the previous owner and I had repeated that mistake. I installed the correct battery and it has worked fine ever since. I suggest that you double check to be sure you are installing the correct replacement batteries.

Are you sure you have the cHave y

Does or did the check engine light ever come on durring all of this ? Or did the alternator light ever come on durring all of this? Jump starting another vehicle, damage to your battery I duoght it, damage to your Alternator and or other electrical componants highly possible if not connected properly.The new battery going dead again could cause all of the problems you have discribed for me. If I were you the first thing I would do is check the new battery and see if it has gon dead now. If so check to see if it is Frozen. If it is frozen you will half to replace it, because once a battery has frozen it will never hold a charge again.Once you have replaced the battery with a good known one (fully charged). Start engine and warm up to normal operating temperature and then disconnect the battery if the engine keeps running then the Alternator is fine . If the engine stalls then you need a new Alternator.A bad Alternator could have ben the problem from the start.I also live in a cold climate zone ( RedDeer, Alberta, Canada).Good Luck and have a good XMSS.

you should check the voltage on your batttery when the car is running. If it reads about 13.5 to 14 volts, your alternator is doing it's job. If it's less, replace the alternator. If the alternator is ok, you have a power drain somewhere, you will need a proffesional to look at it.

could be bad igntion switch not turning off all the way keeping power on

water may have caused corrosion check battery contact points.

sound like a fault in dvd player.its running battery down.have dealership check it out.sound like a electrical problem.

i would take the belt off and then check the idler pulley assembly..it could be worn out..since the belt is off check the alternator pulley for any play also. A loose belt will not help the battery to keep a charge. if everything looks o.k. and you said you have a new battery and belt then it looks like your alternator went bad. Hope this helps.
