Battery Charging; To Obtain The Best Life For The Battery - 909 H144L1 Instruction Manual

Battery charging

IMPORTANT. Before attempting to charge the battery,
check the plug pack, the charger base adaptor and the
battery to ensure the charging equipment matches the
battery supplied. The components are all labelled with
component numbers.
IMPORTANT. The battery will be fully charged after
approximately 3–5 hours: remove it from the charger after
this time. Do not leave a battery charging for longer than
24 hours.
Note.
The battery pack will not charge if the battery cells are
hot. If the pack has been directly taken from the drill after
heavy or constant use, the cells will be hot.
Allow the cells to cool before fitting to the charger base
adaptor.
When the base adaptor is fitted to the battery pack and
turned on, if both red and green lights are on, the battery
is not charging. Either the battery is fully charged, or the
battery is too hot.
DO NOT force cool the pack.
1. As described in the previous
section, "Fitting and removing
the battery pack", fit the
charger base adaptor on to the
battery fully. The charger base
adaptor is retained on the
battery pack runners. It does
not "click" into place.
Note: If the battery pack is incorrectly orientated the battery
will not fully enter the base as depicted.
2. Plug the plug pack into the
charger base adaptor and plug
in the plug pack and switch on
at the power supply. A small
red LED light on the plug pack
will glow when the power
is turned on. The red LED
indicator light located on the
charger base adaptor will indicate that power is available
to charge the battery.
The green light on the charger base adaptor will NOT
illuminate during the charging process, so if the green
light is on the battery is not charging.
3. The charging time is approx 3–5 hours. The red LED
on the charger base adaptor will remain on during the
entire process. The green light will illuminate when the
charge process is complete and the battery is no longer
charging.
4. Turn off the charger power supply from the mains and
then remove the battery pack from the charger base.
Both the battery pack and the charger may become warm
to touch. This is also normal and not an issue of concern.
Both the battery pack and charger are fitted with thermal
safety devices and they will shut down if the temperatures
become too high.

To obtain the best life for the battery

Never allow the drill to come to a complete stand still
before recharging. The battery should be placed on charge
whenever the battery is noticeably running down or the
drill no longer performs a task it previously performed. For
storage, charge between 50 and 75%. Avoid allowing lose
items like screws or nails etc. to be stored with battery
packs as these or similar items can short battery packs
and cause a fire or explosion.
Always unplug the charger when not in use and store in
a dry secure place.
