It is not easy to know how to charge a battery in the correct and optimal way.
There are many parameters which need to be taken into consideration in order to fully change the battery and at the same time obtain the longest possible run time.

 
Charger Technology
The battery’s own technology is always the starting point when choosing a charger.
If you knowwhat type of battery to use there is a choice between two major types of
chargers, CV, CC, or a combination of both methods.
 
Constant Voltage Change
The constant voltage charge method (CV) is usually used for sealed lead batteries.This
methoddoes not demand any intelligence from the charger as the charge current is
controlled by the battery’s IR (Internal Resistance). Read more about the maximum
charge current for respective sealed lead technology in the catalogue listing. The constant
voltage charging method is also use when charging Li-Ion and Li-Polymer batteries, usually
with charge current control.

 
Constant Current Change
The constant current charge (CC) is used when charging NiCd and NiMH. The difference
between CC and CV is that in this case the battery is not controlling the charge from the
charger, hence it is something you have to balance for each cell type and size in advance.
The lack of control between the battery and the charger has resulted in a selection of
numerous different intelligent chargers which “sense” the status of the battery and
consequently will be able to stop the charging without any dangerous overcharge.
 
Automatic Charge Control
The two most well-known ways of detecting that a NiCd- or a NiMH battery is fully charged
is –DV and Dt/Dt. It is recommended that both these methods need to be supported with
a security timer, which is a well known feature and will make sure that you obtain the best
possible result.
