These graphs gives the recharge time
for a current limit of 0.2C
5
amperes.
Clearly, if a lower value for the current
is used, e.g. 0.1C
5
amperes, then the
battery will take longer to charge.
If a higher current is used then it will
charge more rapidly but, does so less
efficiently, and so this is not a
pro-rata relationship.
The charge time for an M type plate
at different charge regimes for a fixed
voltage is given in Figure 6(d).
If the application has a particular
recharge time requirement then this
must be taken into account when
calculating the battery.
