If the charger does not stay on after 10 minutes, disconnect the charger from the
battery. The battery most likely has a shorted cell and needs replacement.
5.
In some cases, a battery, which is discharged completely, will not draw any
noticeable current when the charger is connected and the power cord plugged in. A battery
that behaves in this way is most likely in a "sulfated" condition. The condition is caused by
leaving a battery in a discharged condition for a length of time.
If the Battery is not Holding a Charge
If this condition is encountered, leave the charger on the battery for, up to, one week
and occasionally look at the meter to see if the battery is drawing any current. Connect and
disconnect the power cord and watch the meter, at the same time, to see if the meter
moves, indicating that the battery is drawing some current.
Try using the battery and see if it runs your equipment. If it does but not for a normal time,
repeat the charge and discharge two or three times. The battery may recover. If the battery
does not recover, it must be replaced.
6.
A fully charged Gel type battery can be left in storage for, at least, six months under
normal conditions. If the storage temperature is above 90 degrees F, the battery should be
connected to the charger every three months for 24 hours. At lower temperatures, a "boost"
charge for 24 hours need only be done every six months.
7.
This charger is not recommended for continuous charging of Gel type batteries. The
charger should be disconnected from the battery once the ammeter shows the battery to be
fully charged. Because of the automatic nature of this charger, no harm will be done if the
charger is occasionally left on for a week or two after the battery reaches the full charge
condition.
