Heavy Duty battery

    Is it worth buying a high amp heavy duty battery for a relatively small engined car? Would a higher amp rating of say 480 blow a fuse or anything?

    I have a 300amp battery in my work car, just a 1.3 Mitsubishi. Every morning it seems to lazily turn the engine over and I have jumped it alot recently with my booster pack. It's the second battery in the past year I have put into it. Would my alternator be up to charging a heavy duty battery?

    Thanks

    It could be a lazy starter, not a battery issue.

    And a bigger rated battery wont blow any fuses

    The starter is fine, only stuck a new one into it there recently....

    You should also check your leads going to the starter and your earth leads also. If you have a voltmeter you should have less than half a volt drop between the battery and the starter

    If you've put 2 new batteries into a 1.3 car in a year then there's something wrong with your car not the batteries. Putting a bigger battery in may start the car but there has to be an underlying reason why it's draining the battery and turning over lazily. Have you checked that everything is connected correctly and everything is torqued correct?

    My daughter had a car a while ago that was very slow to turn over, even with a fresh battery or jumped, it turned out to be the alternator getting close to being seized. If you are handy with spanners, slacken off the belt and check does it spin freely.

    A bigger battery will only turn the engine over for longer

    Heavier battery won't make a difference...

    Sounds like either the battery isn't been charged up or something is draining it. If its not being charged properly is more than likely the alternator.

    Its quite easy to test the alternator, by measuring the battery voltage when the car is running, you should see about 13.5V.

    Have you an after-market alarm? car kit? fancy stereo/amp? ipod adapter? these sort of things can drain the battery.

    I put new drive belts on it there before xmas and the pullys were turning smoothly. I checked the connections to the battery and their free of oil and grit and are secured tightly. Battery fluid levels are good, took out the battery and stuck it on the charger and it was well down on power. Been on and off the charger 3 or 4 times since before xmas.

    The battery was fine for about 5 months before it went like this. It's a Global 300 amp battery( korean make). Maybe it's just a sh!te battery?

    I have an aftermarket alarm ye and a new stereo in it with i pod connector.
    I will measure the voltage across the battery tommarow thanks for the tip ;)

    Get the quiescent current of the vehicle measured to check nothing is draining the battery... You can do this yourself with a cheap multimeter. If you need instructions on how to do this, let us know.

    Light in the boot staying on??????

    Been a sneaky problem in the past in other threads.

    I don't have a light in the boot...There is no bulb in it for years.
    I have a sneaky suspicion it's my radio thats doing it as I have it on day and night when driving.

    Its the alternator that runs all your electrics when you are driving.

    A simple test is to disconnect the battery over night and see if it still has the same problems. Sometimes alternators can develop a fault in the diode pack which can drain the battery over night

    If I left the car in the drive for a week, I would have to use the booster pack to start it.... If I have the engine switched off in the car park and switch on the radio for 25 mins while eating my sandwich role, it would just about start afterwards or maybe not... Booster pack saved me in many occasions doing this.

    Is your radio/cdplayer wired properly my daughters car was draining the battery and this was the cause. Dont know the details but getting it rewired sorted the problem.
