The ambient temperature rises rapidly when charging the battery
at room temperature
•
This is normal. The internal ambient temperature is always 0º to 16º
higher than the external ambient temperature. Ambient temperature
is not used for charge termination criteria.
The gas gauge reads full, but the indicator light is still blinking
• If you charge your battery daily, rely on the gas gauge reading to
determine battery capacity. The charge mode may have switched
from Fast to Slow because the battery became too hot. The charging
process is trying to put a little more capacity into the battery;
however, external power can be removed because the battery is
virtually full.
• If your battery is new or has not been used for several weeks, rely on
the indicator light to determine when the battery is fully charged.
The gas gauge is unreliable in these cases; it may read 100 percent,
but the actual capacity is only 10 percent.
My battery seems to have less and less capacity
• To keep your battery at optimum performance, perform a deep cycle
discharge every 2-1/2 to 3 months using the Battery Maintenance
application.
• Over time, your battery may develop memory effect. This occurs
when the battery is partially discharged and recharged repetitively
without a full discharge. A partial or shallow discharge means that
you use less than 50 percent of its capacity before charging. Deep
cycle discharge the battery using the Battery Maintenance
application to help prevent memory effect.
• If your battery is new or has not been used for several weeks, deep
cycling it up to four times in succession may increase its capacity.
You may want to do this over consecutive weekends since each deep
cycle process can take up to 40 hours. After this initial conditioning,
maintain battery capacity by deep cycling at the recommended
frequency.
