What's IME ?

[Mick Dempsey]

It's 2012

 

Get a new one.

 

IME = in my experience.

[Mesterh]

It depends on why it went flat.

 

If it's knackered charging will be a quick fix at best.

[Stubby]

Trickle charge it over night , check the voltage on each cell .

Hi,

 

If a 12V lead/acid battery goes below 10.5 volts then its usually scrap.

 

No matter how much you try & charge it it wont hold charge because some or all of the cells will be defective.

 

If you have a CTek or similar charger then you may be able to do a restoration charge &/or charge to 15 Volts ( or the voltage prescribed for an equaliser can be upto 15.6 V ) where each cell will gas so loosen tops & check the water level, top up afterwards.

 

If you have a voltmeter, measure the terminal voltage, once it reaches 15V (or equalising voltage) switch to a lower current setting so it dosnt gas excessively & gas for around 3-4 hours @ the equaliasing voltage.

 

What this will do is expose fresh lead so it re-vitalises the battery

 

If that dosnt work then change it.

2012 highly unlikely to have failed that quick. Batteries normally last around 8 to 12 years now. Most probable cause is something draining it. Light left on etc. As said charge it overnight. When did you use the freelancer last?

Lots of small drains now immobiliser etc so battery's only last a few weeks before they don't have enough charge to start the engine

We've got a transit that has started discharging it's battery, I cannot find where the drain is but until I do I have been pulling the earth terminal, means I have to re enter the radio code when I want to use it.

 

Yes modern batteries seem good for that sort of time unless they get profoundly discharged which can knock years off.

 

My last battery in the 206 was 10 years.

Just had to put two new batteries in my Tranny, 10 years old.

New alternator as well unfortunately.

What's the voltage? Needs to be over 13v...

Time I'd jumped the Tranny and limped it to my mates garage both batteries read 10.6v.

Didn't seem worth asking a new alternator to perform miracles.
