1.5 Ah| 2.5 Ah| 4.0 Ah
10.8 V| BSL1215
(3 cells)| 22 min| BSL1225M
(3 cells)| 37 min| BSL1240M
(3 cells)| 60 min

NOTE The recharging time may vary according to the ambient temperature. In addition, the charge time becomes significantly long in a low-temperature environment, but this is not abnormal.
4. Disconnect the charger’s power cord from the receptacle.
5. Hold the charger firmly and pull out the battery.

NOTE
Be sure to pull out the battery from the charger after use, and then keep it.
Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and the normal time required for recharging will be restored by recharging the batteries 23 times.
How to make the batteries perform longer.

Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
Avoid recharging at high temperatures. A battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (off for 0.5 seconds). In such a case, first let the battery cool, then start charging.
When the pilot lamp flickers in red (at 0.2-seconds intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
Since the built-in microcomputer takes about 3 seconds to confirm that the battery being charged with UC12SL is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
When disposing of the battery, remove it from the appliance and dispose of it safely.
When not using the appliance for long period of time, detach the battery from the appliance.
Do not allow the charging terminals to become short-circuited. When inserting the battery, ensure that the polarity direction is correct.
