Battery problems 2002 SType

[Mike52]

Hi

I have a 2002 S Type 2.6. i have had a new battery twice in the last month the first went dead and was diagnosed with a dead cell by the RAC.

I replaced with a new  one which was delivered under charged. I charged the new battery and put in in the car. After 5 days i restarted the car only for numerous warning lights to come on including the battery light. All the lights immediatelyly went off when i started driving the car. Any suggestion anyone? This battery problem is driving me nuts.

Thank you

You most likely have a parasitic drain on the battery from a defect within the car. These can be troublesome to track down.

A few things to check, there is a little flap on the ignition barrel, when the key is removed it should close. Check all auto functions are switched off. Make sure you double lock the car when left unattended, even when in a garage.

In the meantime, a CTEK battery maintainer will help keep the battery fully charged.

HI

not sure which one you have as they dont make a 2.6, so assume its a 2.5 petrol or 2.7 diesel

Its always usually the battery, if the battery came undercharged, I'd sent it back, some batteries once they get below 10 volts are never the same again

but sounds like you have a battery drain problem, which is flattening the battery

short term use a smart charger like a CTEK, long term you need to find whats draining the battery

have a read of these
