5 hours to completely charge. Under extremely cold or hot temperatures, however, the battery can
take up to 16 hours to fully charge.
The batteries don’t last very long

Calibrate the battery using the Battery Calibration selection in Mobile Computer Tools. If your
battery is new or has not been used for several weeks, calibrating the battery over a weekend may
substantially increase its capacity.

As your battery ages, the maximum capacity that it can hold naturally decreases, and even the best
maintained batteries eventually need to be retired. Consider replacing the battery if you are not
getting the usage you need from it.
The gas gauge isn’t full after charging the battery

This may indicate that the charging process terminated prematurely.
The gas gauge reads “full,” but the charging indicator light is still blinking

If you charge your battery daily, rely on the gas gauge reading to determine battery capacity. The
charging process may continue even if the gas gauge reads full. External power can be removed
because the battery is virtually full.
My battery seems to have less and less capacity
