CHECKING AND CHARGING THE BATTERY

• If the battery becomes hot to the touch at

any time during the charging process,
disconnect the battery charger and let the
battery cool before reconnecting it. Hot
batteries can explode!

• As shown in the following illustration, the

open-circuit voltage of an MF battery sta-
bilizes about 30 minutes after charging
has been completed. Therefore, wait 30
minutes after charging is completed
before measuring the open-circuit volt-
age.
