age should drop rapidly (within one minute). A properly charged pack
will slowly drop voltage from a high of around 14 to roughly 13 volts, and
should hold 13 volts for about an hour.
5. The charger will enter a "maintenance stage" when a full charge is
reached, so it is possible to leave the baery connected to the charger
for extended periods of me. If the baery is going to be le unused for
several weeks, charge the baery, disconnect the baery and charger for
the length of storage, and then top o the baery with a new charge prior
to the next use. If the baery is to be stored without use for a long period
it should be topped o with a recovery charge every six months.
Burn Testing
You should burn test your baery pack at least yearly in order to establish
the actual burn me of your light. Frequent divers, or those who oen rely
on longer burn mes, may choose to test their light more frequently. In order
to conduct an eecve test you will need the following equipment:
•Baery pack
•Discharge method: either the light head itself or a discharge array
•Volt meter
•Timer, preferably with an alarm
•Reservoir of water
•Paper to record me and voltage
The following steps will allow you to accurately determine your baery's
burn me:
1. Make certain that the baery has been fully charged. For the best charge,
burn the baery for ten minutes and then bring it back to a full charge.
2. Place the light head into the water. Make sure that there is enough water
to prevent overheang. A one gallon basin or bucket is sucient.
3. With the baery out of the canister, connect the light head to the baery.
4. Actuate the switch and measure the voltage. For NiMH baery packs, back
the lid away from the baery enough to allow you to insert the volt meter
probes tomake contact with the metal posts. Do not allow the probes to
touch each other while in contact with the baery terminals.
5. Record the me and voltage every ten minutes unl the pack reaches 10
volts. It is recommended that the mer have an alarm to alert you when
an interval has ended. The alarm will prevent you from forgeng about
the baery and discharging it completely. A complete discharge is prac-
cally certain to damage the baery's cells.
6. Stay near the pack to monitor the voltage decay as the 10 volt limit is
approached. As the pack nears 10 volts, the voltage will drop more rap-
idly. Record the me when the baery reaches 10 volts. This me is the
amount of me that your light baery can provide a useful light beam.
