If the battery is not to be fitted immediately, ensure that the metal contacts are
protected so as to avoid the possibility of a short circuit which would cause
damage.
Remember to avoid extremes of heat or cold when charging.
NOTE:
Ni-Cad batteries as used in Clarke Cordless Drills should be given a full charge
when first supplied new. Maximum battery performance will be achieved after
approximately 5 complete charge/discharge cycles.
Protect batteries from extremes of temperature at all times, but especially whilst
charging.
Minimum 4°C.
Maximum 40°C.
Avoid placing batteries in direct strong sunlight or any other heat source. If the
battery becomes warm, disconnect and allow it to cool down for a few minutes.
Nickel cadmium batteries will slowly lose their power whilst in storage. A periodic
re-charge is therefore recommended.
Do not leave the batteries in a discharged state for any length of time.
IMPORTANT:
The full capacity of a Ni-Cad battery will only be realised if it is allowed to
discharge almost completely before once again being re-charged.
Constant topping up after only a small amount of charge has been used will, in
effect, reduce its capacity
To achieve the ideal objective, particularly if the drill is in regular use, it will be
found useful to purchase an additional battery.
BATTERIES - IMPORTANT NOTES
After being re-charged many times, nickel cadmium batteries will eventually lose
their ability to hold the charge. This will be evident if power is lost much sooner
than usual after a complete re-charge. In this case, such batteries should be
replaced. Dispose of old batteries with consideration for the environment. They
may be returned by post to the Clarke Parts and Service Centre ( see page 3)
where you can be assured they will be disposed of safely. Alternatively, seek advice
from your local waste disposal authority. Do not incinerate or crush, as this will
increase the risk of explosion and contamination. If the battery contents should
under any circumstance be spilt wash away with soap and plenty of water. Vinegar
or lemon juice will also help to neutralise the harmful effects of the battery contents.
If these come into contact with skin or more especially the eyes, rinse with clean
water for several minutes and seek medical advice immediately afterwards.
NOTE: A complete charge will take approx. 3 -5 hours, depending on the state of
the battery, and after this time the LED will extinguish. The battery may then be
removed and the power switched off.
