This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2-3 times.
How to make the batteries perform longer.

1. 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 curent, the battery may be damaged and ts life wil become shorter.

2. Avoid recharging at high temperatures.
   A rechargeable 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 awhile.

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 lightfor 0.5 seconds (off for 0.5 seconds). Insuch a case, first let the battery cool, then start charging.
• When the piot lamp flickers (at 0.2-second intervals), check for and take out any foreign objectsinthe charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is maliunctioning. Take it to your authorized Service Center.
• Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with charger 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 property charged.  If the pilot lamp does not blink in red (every second) even thoughthe charger cord s connected to the power, itindicates that the protection circuit of the charger may be activated.
  Remove the cord or plug from the power and then connect it again after 30 seconds or so If this does not cause the pilot lamp to blink in red (every second), please take the charger to the HIKOKI Authorized Service Center.
