My battery on my MU has gone flat twice in the last two weeks (about a week apart). What can be reasons for this happening? besides the obvious that the battery has probably had it? Could the stereo system being used regularly drain the power that much? What could be wrong with the battery? cheers BTW, I dont know squat about batteries  |

Mine has done this twice now, after 4 years of owning it. I think in my case it's the alarm that's draining the battery as the alarm uses power all the time and has active internal sensors. First time I replaced the battery with a 600cca 15 plate job, this time I got a 700cca mother of a battery for about $150 at Supercheap. It dropped straight in and has been working a treat. I had to replace the battery in the other car a month before. It received a 550cca Exide, but the little 1.5L Toyota needed some modifications to it's battery mounting brackets because it's a much bigger battery than standard. The good news is that I've left the lights on for 4 hours and the car started without a hitch. I'm now very fond of large powerful batteries in my cars  Back to your battery - do you have an alarm, turbo timer? Leave the stereo or lights on at all? Especially the light in the back, that caused a couple of flat batteries for me. Oh yeah, I've just found that my power antenna doesn't always go down completely, and when it's stuck, I think it's still drawing power. It might be that it always draws power, I don't know but may try to find out soon. Cheers, Graham. |

You might want to check the electrical wires from the battery to the alternator.. Some times if these are oiled up they dont give a good connection and wont sent much charge back to the battery. Give them a quick spray with some C.R.C or something similar.

I do not have an alarm or turbo timer, but before it went flat I was playing around with the stereo for about 15mins. What can I do to check that my battery is working to its full potential? cheers |

take it into a garage and get them to test it, most workshops will have a simple battery tester that clamps onto your terminals and simulates starting load. Generally batteries will start to fail around this time of year as the nights get colder and they don't hold their charge as well as they used to. Should only take 5 mins to check it so most garages won't charge you to do it either

Do you know what the culprit was? How did you fix it?
