Auxiliary Battery Upgrade

Over the last few adventures that we have taken in our Toyota FJ Cruiser and especially the trip to Alaska I found that I undersized the auxiliary battery. The battery was getting run down most nights and I was even having problems with is getting fully drained at home.

Original Auxiliary Battery

I am a believer in the Odyssey batteries and there performance and durability. With the Sears Platinum Battery being made by Odyssey there are some cost savings by purchasing from Sears.

New Battery Installed

My old battery, the PC1200 was rated at 40 amp hours. The new group size 34 battery from sears is rated at 68 amp hours. This is almost double the capacity. Another advantage of the Odyssey batteries is they can be mounted in any orientation. This allowed me to mount the battery on end which allowed it to fit in the limited space available.

Applying a full charge

When charging Odyssey batteries a charger designed for these  Absorbed Glass Mat  batteries must be used. I own a charger from Odyssey that can charge multiple batteries at the same time.
