I will remove each battery and check them with a meter and charge them if need be as I have the MTH Charger
Note that a voltmeter will not accurately read the charge of a battery, rather, it will often read a higher "surface charge".
You should test a battery in one of two ways:
- Using a battery test device specific for that battery's stated voltage.
- By holding a small light bulb to the battery's contacts for several seconds. If it starts out reasonably bright and then quickly (after a few seconds) dims, the battery needs to be charged.
If a battery fails a test after charging, it should be replaced.
