Battery Life K2

[Chas Nagel]

Has anyone had any long term experience with the K2 battery? I think I used it once for about three hours a couple of field days ago. Now at 14.2 volts over a couple days' charge I can't get above 11.6 volts.

Charles,

That is one sign that the SLA battery has seen its "end of life".
I figure about 3 to 5 years on any lead acid battery - trying to make it
last longer is pushing your luck.
If it is something you are going to rely on for emergency use, replace
it every 3 years (in my opinion).

Charles you have a shorted cell within the battery. It is a fatal error. The
battery must be replaced. Shorting of cells occurs when the battery is
allowed to remain in a discharged state, particularly in freezing weather.
