Flat Battery Please Help!

[HaZ3inSKY]

Hey fellow RB lovers,

I didn't start the car for a week because I had to replace the crossover pipe. When I tried to start it up it was totally dead (i may of left one of the interior lights on). So I jump started it and it started up fine, I left it running for bout 2hours to charge. I then switched it off. I tried starting it again but now it just clicks when I turn the key and the internal lights flash.

I jump-start again but left if longer...bout 4hours, din work again. I repeated the process a 2-3 times, the damn battery wont charge!!! So I charged the battery using a battery charger, din work either. and also checked the fuses aswell!! What shud I do? Maybe a new battery but which one?

Please guys I need ur help!!

To charge your battery go for a little drive. It's better than just leaving the car there idling. The higher the car's revving the more it's charging.

Best to get a new battery. If that still doesn't charge up and gets flat. It could be a problem with your alternator.

check the fluid in the battery mate. its only like $3 to top up.

then take it for a spin for about 20 min..

Should be fine after that

unless you have to many dead cells in the battery

buy a new battery. go with a gell long life battery or a sealed battery. but they are a bit pricey.

cut your losses man. stop wasting time and money. do it, and move one.

like said, buy a new battery. those fluid type leadcell bateries will die completely if you run them flat. if you dont want to have to worry about that again, spend a bit more money and get a deep cycle, sealed battery, like offered by optima, or odyssey. these can be run flat, and recharged many times, without killing the battery. people get up to 8 years life out of a battery

he should be running a sealed battery if im not mistaken.

just get a new bat if you can afford it.

Cheers guys! I jump started it and took it for a run. when I came back and turned off the engine...it wouldn't start again. I'm gonna take it to a mate of mines to check if it is the alternator or the battery. How much is a good battery these days?

it wont be the alternator mate. hook up a charge light. u will be able to see the charge output from the alternator to the batt. u will find it is in the green.

for another alternator test. turn on your headlights, and rev it. now if the lights dim and brighten really noticably it MAY be the alternator failing to put out enough charge, but fairly unlikely.

Also check to make sure the Earth cable hasn't come loose, etc.

Would also cause it to not charge.

PROBLEM FIXED GUYS Apparently it was both the battery and the alternator.

[Jmaac]

Sounds like it was just the alt. regulator and/or brushes... they trick you into buying a whole new one? Your windings would of been fine for a car so young

Your lights wont dim if you rev it. They will dim if you dont cruiser

[Jonnygtr24]

sound like alternator to me. if u replace a new battery and still have that problem best to bring ur car to machanic to check the alternator. if it was the alternator then u may need to recondition it.

wait wait wait.... you left the car to sit there and IDLE away for 2 and 4 hours? lol hahahaha wtf

[benm]

I let my work van idle for 5hrs last weekend, jump started it then went inside to watch the final round of the v8's then went out after to do some shopping and realised it was still idling away in the backyard, ahh toyota's - love em!

stupid nrma battery is still dead tho.

news flash... if you flatten a lead-acid battery and leave it that way for more than a day s it is CACTUS. if your battery goes flat overnight and you jump start it the next day and take it for a drive you'll be ok, if you leave it for a couple of days or a week then buy a new battery. don't even try to charge the flat one, it has sulfated and is no good.

lead acid batteries will last for years if you store them fully charged but leave them dead flat and they'll die after a day or two. after that they'll never hold a charge again.

probably the damage to your alternator was caused by trying to run the car's electrical system and charge a dead flat battery at the same time. should have just bought a new battery and put it in when you realised it had been flat for a week.
