Hi,
I have dual batteries both being Oddysee and this morning I tested their voltage while not under any load and without the car being driven for about 12 hours.
They both read about 12.25 volts?
These batteries are between 3 and 4 yers old and was wondering if the voltage seemed a little low and weather or not they are showing signs of ageing or possibly failure?
I also use an ARB smart solenoid.
Any comments would be greatly appreciated.

Thanks
Chris.

cobes,

12.25 equates to about 65% charged. A bit low if they haven't been in use for a while. You should be getting at least an 80% charge from your vehicle alternator which equates to 12.42 volts minimum at rest.

Are they a Deep Cycle Battery?
Are these batteries a wet cell technology?
Are they a sealed unit or do they have removable caps?

If you can access the individual cells use a hydrometer to check battery health. This will indicate straight away if one or more cells are crook.

3-4 years old is reasonable for a "normal" starting battery. (rated in CCA's)

They are a starved electrolyte "dry" cell, with a miniscule gas vent. They are military grade batteries, with somewhat different charge/discharge characteristics than the usual "sloppy" or SLA. Should last 8-12 yrs.

Chris,

On the surface it would sound like they are near to stuffed.

Best way to check then out is pop into a battery place (eg Battery World) and get them to do a proper load test with a professional battery checking device.

Cheers,

Jim.
