BCL 1015
Equipped with new lithium-ion battery (BCL 1015)
The Type BCL 1015 lithium-ion battery (10.8/12 V PEAK, 1.5 Ah) can be fully charged by using the Model
UC 10SFL Charger in about 40 minutes.
The Type BCL 1015 is equipped with an overdischarge protection circuit, overload protection circuit, battery
overheat protection circuit and voltage monitoring circuit for each cell to prevent any reduction in battery
service life due to overdischarge (overuse) or overcharge (excessive charging). This battery is safe thanks
to these protection circuits.
Precautions on using the Type BCL 1015 lithium-ion battery
The Type BCL 1015 lithium-ion battery is equipped with a protective function that automatically stops output
to prolong battery service life. The motor may stop automatically due to the causes described in (1), (2) and
(3) below, even if the switch is continuously pressed during operation. This is because the protective
function described for each cause is activated. The motor is not faulty.

Explanation of 12V Peak :
Initial no-load voltage, when fully charged, peaks between 12 to 12.4 Volts.
During the battery cycle under a typical load, voltage averages at 10.8 Volts.
