Ni-MH Battery Q&A:
Question: Why does my Ni-MH battery pack only last for a few minutes after charging?
Answer:
The Grasshopper™, Locust™, Yellow Jacket™ and Yellow Jacket
Plus (fomally called Scorpion), Beetle™, Cricket™, and Cicada W-LAN
receivers use 4 or 5 Ni-MH long-lasting "AA Cells".
1. Ni-MH batteries do not charge to full capacity the first time they are
charged.
2. Ni-MH batteries do not charge to full capacity the first time they are
charged after a long period of inactivity. or after a long period of non-use.
Cause: When charging Ni-MH batteries for the first time after long-term storage, deactivation of reactants may lead to increased battery voltage and decreased capacity, (which causes premature termination of charging). Because batteries are chemical products involving internal chemical reactions, performance deteriorates with prolonged storage. This is normal in Ni-MH batteries.
Resolution:
Ni-MH batteries may not charge to full capacity the first time they are charged,
or after a long period of inactivity.
The first-time charge of the Ni-MH Rechargeable Battery Pack should take approximately
2 hours. If the Receiver Dock light turns green, indicating a full charge,
in less than 2 hours, repeat the charge cycle as follows:
First-time
Charge:
1. To begin charging, place the instrument on the Charge Dock. Refer to your
instrument's User Guide for details.
2. When the charge light turns green, remove the W-LAN Receiver from the dock
and place back on the dock after several seconds.
3. Repeat steps 1 and 2 three or four times or until the combined charge time
is 2 hours.
Subsequent charges of the W-LAN Ni-MH Battery Pack will not require multiple
charging cycles unless left uncharged for a long period of time (greater than
2 months).
