|1. My batteries
don't seem to hold a charge. What is the problem?
When the charger is connected to the AC adapter you should
see a solid red light. This indicates that the charger is
ready for a battery. When a "cool to the touch battery"
is inserted in the charger, a solid green light on the charger
will come on. This indicates the charge function is working.
When the battery is charged, there will be an audible sound,
the gauge will be solid black and the green light will begin
to flash. If, after charging, the battery life is low, you
should use the refresh function on the charger. If, after
the "refresh" function, the battery life remains
low, the battery needs to be replaced.
Please read the following information on NiMH batteries.
This applies to both new and older batteries and may be
All SnakeEye base kits are supplied with two high capacity
Nickel-Metal Hydride batteries. The batteries must be charged
and conditioned before use. By following this procedure
you will insure the fullest capacity of the battery will
be available for use.
To condition the battery place the battery on the charger
and let the battery come to a full charge. After fully charging
the batteries press the refresh button on the charger. Repeat
this operation for three cycles. You will have pressed the
refresh button a total of three times. Your battery will
now be at its full potential.
Nickel-metal hydride batteries are exothermic (give off
heat) during charging and discharge. Elevated temperatures
will have an adverse effect on the ability of the battery
to accept a charge. Let batteries cool to ambient temperature
before attempting to charge. Failure to do so will not allow
the battery to accept a full charge.
Temperature Effect on Battery Capacity (usable capacity
Temperature Battery Capacity Available
-4ºF (-20ºC) 20%
1 4ºF (-10ºC) 50%
32ºF (0º C) 80%
50-86ºF (10-30º C) 100%
104ºF (40º C) 90%
122ºF (50º C) 80%
Temperature effect on self discharge rate (usable capacity
of battery after storage).
All rechargeable batteries self discharge during storage.
Storage temperature has a significant effect on the rate
of self discharge. Never store the SnakeEye with the battery
installed in the unit.
Approximate capacities for nickel-metal hydride batteries
77ºF (25ºC) 20 days 75% capacity
98ºF (37ºC) 20 days 50% capacity
118ºF (48ºC) 20 days 10% capacity
140ºF (60ºC) 15 days 0% capacity
If you require 100% readiness at all times you will need
to develop a battery maintenance program that will insure
you have 100% charged batteries always available. If your
use is periodic you should allow time to recharge the batteries
before using SnakeEye.
