The charging process of a fully discharged battery will take approximately 5 hours the first time and
afterwards approximately 3 hours.
As soon as the green trickle charging lamp lights up, charging has been completed and the deviceis ready
for operation.
Discharging the battery
Not only charging batteries is important, discharging is of equal importance oreven greater
importance.
When the battery is charged the cordless drill has to be used until you start noticing that the power of the
drill is diminishing and that the maximum rotational speed is not reached.
The battery is almost discharged now. Only now you can start charging the battery.
Charging the battery while it is still charged for say one-third of capacity, the so-called 'memory effect' can
occur. Since during charging only the discharged part of the battery capacity of the battery is being charged
now, the battery can start crystallizing in the one-third that is still charged. This part of the battery capacity
can never be used afterwards.
Do not discharge the battery to the minimum. As soon as you notice that the power or the maxi mum
rotational speed is diminishing, you have to charge the battery. When you proceed using the drill and the
battery becomes fully discharged, the so-called 'switch of poles effect' can occur. The polarity of the battery
poles will be switched: the '+'will become '-'and the '-'will become the '+'. Once this has occurred the
polarity will remain switched during loading and this will damage the battery irreparable.
When the cordless drill is not being used over a longer period of time, the battery has to be charged
fully first. The battery has to be stored in charged condition.
Battery
The length of service from each charging cycle will depend on the type of work you are doing. The battery
in this drill has been designed to provide maximum trouble free life. However, like all batteries, they will
eventually wear out.
To obtain the longest possible battery life, we suggest the following:
Store and charge your battery in a cool area. Temperatures above or below normal room temperature will
shorten battery life.
Never store batteries in a discharged condition. Recharge them immediately after they are discharged.
All batteries gradually lose their charge. The higher the temperature the quicker they lose their charge. If
you store your drill for long periods of time without using it, recharge the batteries every month or two.
This practice will prolong battery life.
