Charger runs too long but does turn off
In the event of AC power interruption when the charger is on, the charger will automatically
restart when AC power is restored. This power outage can make the apparent charge time
seem longer than the actual charge time, which has a maximum run time of 16 hours. To
check for AC power interruptions, plug an electric clock into the same outlet to which the AC
input cord is connected. Charge normally and note any time difference between the test clock
time and the actual time.
Charge time on new batteries will generally run longer as the internal chemistry of the battery
continues to change during its break-in period of about 20 cycles. During this period heavy
gassing from the battery is normal.

AC LINE FUSE OR CIRCUIT BREAKER BLOWS
If this occurs when the charger AC input cord is connected to an outlet, without the DC output
plug connected to the battery receptacle, the charger’s AC input cord may be shorted. If this
occurs just as the electronic charge controller’s relay closes, a shorted transformer primary coil
could cause this to occur. Refer to the Component Test Procedures section to check each of
these potential issues.
