12. Battery capacity display button

• Press the remaining battery capacity display button to light the indicator lamps and indicate the remaining battery capacities. The indicator lamps correspond to each battery.

NOTE:

• When only the lowermost indicator lamp blinks for either Battery 1 or Battery, this means that the battery capacity is low, so the product does not operate. In these cases, charge the battery that is low, or replace it with a fully charged battery. The product does not operate when either of the batteries has run out.
• The indicated charge may be slightly lower than the actual level during use or immediately after using the product.

How to read the remaining battery capacity indication

Indicator lamps (Battery 1 or Battery)			Remaining charge or indication contents
: On	: Off	: Blinking
			50% to 100%
			0% to 50%
			0% to 20%
			Charge the battery

• Depending on the conditions of use and the ambient temperature, the remaining capacity may not be indicated correctly.

Abnormal indications during use

The BCV03 indicates various states using the remaining battery capacity indication.

Indicator lamps			Indication contents
:On	: Off	: Blinking
Battery 1		Battery 2
			The BCV03 may have malfunctioned.
			The protective function operated.
			The protective function operated.
			Charge the battery.
			The BCV03 detected an abnormally high voltage.

1. BCV03 malfunction
   When the three indicator lamps for Battery 1 and the three indicator lamps for Battery light alternately, the BCV03 may have malfunctioned. Contact your Makita dealer or nearest Makita Sales Center to request inspection and/or repair
2. BCV03 protective function
   When a product is used continuously at a high load, the motor may stop automatically. This is due to the BCV03's protective function, and is not a malfunction. If the product does not operate even when the product switches are operated, stop use, disconnect the product and batteries from the BCV03, and let the BCV03 cool down.
   
3. Battery protective function
   The batteries have an internal protective function that automatically stops power output in order to extend the battery life. When the following states occur during product use, the motor stops automatically, but this is due to the battery's protective function, and is not a malfunction.
   When the battery temperature rises above a certain level, the motor stops automatically, and remains stopped even when the switches are operated. In these cases, stop battery use, remove the batteries from the BCV03, and allow the batteries to cool or charge the batteries.
   When the battery capacity becomes low, the product's motor stops automatically. If the product does not operate even when the switches are operated, remove the batteries from the BCV03 and charge the batteries.
   
4. BCV03 abnormally high voltage detection
   When the BCV03 detects an abnormally high battery voltage, the motor stops automatically. This is due to the BCV03's protective function, and is not a malfunction. In these cases, the motor remains stopped even when the switches are operated. Remove the batteries from the BCV03, and use different batteries with normal voltage.

NOTE: When the product stops automatically without any BCV03 indication
When the product enters an overload state, power output stops automatically in order to extend the battery life. This is due to the battery's protective function, and is not a malfunction. In addition, in these cases the BCV03 does not indicate anything, but this is not a malfunction. When this happens, release the switch, and remove the cause of the overload. The product can then be used again by operating the switch again.
