CHARGING METHOD: (CONTINUED)
4. Disconnect battery charger from the receptacle.
CAUTION: DO NOT PULL THE PLUG OUT OF THE RECEPTACLE BY
PULLING ON THE CORD. MAKE SURE TO GRASP THE PLUG
WHEN REMOVING FROM RECEPTACLE TO AVOID DAMAGING
CORD.
5. Remove the battery from the battery charger. Supporting the battery charger with
hand, pull out the battery from the battery charger:
a. When the battery charger has been continuously used, the battery charger
will be heated, thus constituting the cause of the failures. Once the charging
has been completed, give 15 minutes rest until the next charging.
b. If the battery is recharged when it is warm due to battery use or exposure to
sunlight, the pilot lamp may light in green. The battery will not be recharged.
In such a case, let the battery cool before charging.
c. When the pilot lamp flickers rapidly in red (at 0.2–second intervals), check for
and take out any foreign objects in the charger’s battery installation hole. If
there are no foreign objects, it is probable that the battery or charger is
malfunctioning. Take it to your JOHN DEERE AUTHORIZED DEALER.
d. Since the built-in micro computer takes about 3 seconds to confirm that the
battery being charged with UC24YFA 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.
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 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 current, the battery
may be damaged and its life will 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 a while.
