toothbrushes, cordless shavers, cordless drills, cellular
and portable phones, and a whole mess of kitchen appliances
rely on rechargeable batteries to keep them running. What
do you do if they won't charge?
Make sure the charger cord is plugged in
and the outlet is getting power.
Look closely at the battery pack. Is there
corrosion or leakage? If so, replace the battery immediately.
Test the charger. For DC chargers, set a voltmeter
to 25 VDC and touch the contacts with the probes. The meter
should read about 1 V more than the charger's rating. If the
reading is zero, switch the probes.

Test an AC charger by setting a voltmeter
to 25 VAC. Touch the contacts with the probes. The transformer
in the charger is bad if you get no reading at all.
Check the contacts. These are metal strips
or points located on the appliance and in the charging base.
With the charger unplugged, wipe them with a cotton swab.
Use a fine emery board to remove visible corrosion.
If you've noticed that the appliance has
been holding a charge for shorter periods, suspect the battery,
not the charger.
A charger's rated output is usually located
on a label on the bottom of the unit.
Avoid testing AC chargers rated higher than
25 V.
Be careful with leaky batteries. The highly
corrosive contents can damage just about anything they touch.
