12V battery

Was digging through my ice fishing gear tonight and need to replace the 12V batteries on the camera and depth finder. Both came with a 7AH battery. Any harm in buying and using a 8AH or 9AH on them? Or is the life just longer for these batteries?

No harm in running them on the higher amp batteries. One questions is if they will fit in the battery compartment for those devices.

So I take it they maybe bigger than the 7A? I'll have to check it out at Fleet. Is my thinking correct that they will last longer?

[bmc2b]

yes, 25-30% longer (9amp vs 7amp)

bmc2b is absolutely right. If you have sensistive stuff like a GPS be sure to install a fuse in the line. I have a fuse running to my Ice Machine, but it would be required for the 6 and 7 AH too.

Get the biggest one you can fit in your compartment, and the biggest one you want to carry around.

Check out the Vexilar "Sportsmans" batter which is a 9amp in the same footprint as the 7amp. Thats what I replaced my battery with. A little heavier, but a lot longer run time.

I just ordered one from a big auction site for 13.75 and shipped to my door in 2-3 days for free.
