4.  Disconnect battery charger from the receptacle.

 

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.
