Battery Charge Time Calculator |
|
This is designed to calculate the maximum battery charge time for any given
chargable battery, based on the entered information. It will calculate the
missing value of the first three entries; one must be left blank. All calculations
for efficiency loss will be done no matter which value you are trying to
calculate. The normally accepted standard for efficiency loss is 20%. Although
10% and no loss are virtually impossible, we have included the potential
for reasons of understanding. 30% and 40% are far more likely than 10%.
If loss is above 40%, you should attempt to find the reason by changing
the charger or replacing the battery. Typical entries for our calculator
might be a 1000mAh rating and 50mA of charge current. That would yield a
realistic charge time of 24 hours. Click on Calculate after entering either
of the two values. |
