7.5.3 Charge Indicators
Each battery charge slot is equipped with a tri-coloured LED to indicate the charge
status of the battery. When 7535 batteries are inserted in the charger, the colour and
behaviour of the LEDs associated with the charge wells in use indicate the status of
the charge.

7.5.4 Charging Batteries
• Install the battery with the battery contacts facing the charger. Slide the
battery between the guide rails until it lightly latches in place.
The LED directly below the slot in which a battery is inserted lights up immediately.
A solid yellow LED indicates that the battery is being charged. If the battery
temperature is outside
0˚ C to 39˚ C (32˚ F to 102˚ F), the LED flashes yellow until the
temperature is acceptable. A fully discharged battery will normally take between 1.5
and 4 hours to charge. When the battery charge reaches 75%, the indicator flashes
green. At full capacity, it turns solid green.
When the battery is fully charged, the charger stops applying power; the battery
cannot be overcharged if left in the charger slot. The 75% charge indicator is handy
if you need a quick recharge – it often occurs after less than an hour.
