Thread: AGM Starter Battery - Jag V12

You can use something like this DC Clip on ammeter ToolPRO AC/DC Digital Clamp Meter 400A & 600V | Supercheap Auto or put an ammeter in series by disconnecting the battery and putting the leads between the battery post and and battery terminal, starting on the highest scale as you don't want to pop the ammeter with over current.

With the car sitting the battery goes down to 11.5v over about 5 days but is still able to start the car.

Charged the battery over night and disconnected it from the charger this morning - while on charge shows 13.4v and when disconnected goes straight to12.7v - by mid afternoon it had dropped to 11.3v and while it will crank a bit, it will not start the car.

So it would seem that the nice and expensive AGM battery has died after just 2 years. I have a nice big RRS battery that is spare that would suit the Jag very nicely but it is physically too big to fit.

So the decision is whether to get another AGM of the same size Odyessy or just go for a standard starter battery.

Definitely not paying $650 for another Odyessy.

A battery in the boot can't be a flooded wet cell unless it has an external breather fitted, so another AGM is likely required.

Check the warranty on the battery, I think they are 3 years for private use.

Oh OK - had not thought of that. Technically the boot is ventilated as air from the cabin goes into the boot and then out through vents in the rear boot floor - but yes is something to consider.

Thanks

Yes thought of that - battery was bought by the previous owner interstate - will probably be too much hassle to claim but will look into it.

Thanks
