STORAGE
For extended periods of storage, the cell pack should be removed, the halogen
lamp removed from the socket and stowed and the housing should be closed.
Place the cell pack on a suitable surface (non sensitive) and store in a dry
environment between 10° - 20°C (50 – 68°F). Under n o circumstances should the
lamp be subjected to temperatures above 45°C (110°F ). If a cell pack is
continuously stored at full charge and increased temperatures, the cell pack will
suffer from an irreversible reduction of capacity of more than 10% per year.
If the cell pack is to be stored for an extended period of time, the cell pack
should be stored at a low temperature with a capacity of 50-60%.
The irreversible loss of capacity due to natural loss of capacity over time can be
reduced to as little as 3% with good care and attention. The lithium manganese
cells are subject to a very small natural discharge (depending on the ambient
temperature this is approx. 4-8% per month, and the electronic in the lamp that
monitor the conditions result in approx. 3% discharge per month).
If the cell pack is stored for extended periods of time, it should be
recharged every 4-6 months to approx. 50-60% capacity.
A completely discharged cell pack is protected by the electronic monitoring
that prevents further charging. In this case, return the cell pack to the
manufacturer for evaluation.
CHARGING
GENERAL INFORMATION CONCERNING CHARGING RE-CHARGEABLE CELLS
The lithium manganese re-chargeable cells used in this lamp have been
declared as gas and acid/alkali sealed. For this reason the electrolyte in the cells
cannot escape and the cells can be charged regardless of their environment. This
positive feature has been stated by the cell manufacturer but an exception to this
cannot be ruled out.
Re-chargeable cells can, if defective, produce an internal pressure in the
cell during charging/discharging (use) that may cause the over pressure
device integrated in the cell to open. This in turn will allow electrolyte to escape
from the cell. Electrolyte is an aggressive alkali and also conducts electrical
current, this will destroy the cell over time. The resulting electrolysis will create an
over-pressure inside the housing of the lamp.
Warning !
In case of a defective cell, the lamp is equipped with a mechanical and
electronic over pressure indicator. After charging the lamp with the housing
closed, check these indicators and ensure that there is no over pressure
inside the housing. (see page 15).
MEMORY-EFFECT
The so-called memory effect will occur when re-chargeable cells are regularly
charged in a partly discharged state (for example this occurs when a wireless
telephone is placed in the charging station every evening). The popular rule of
thumb to only charge re-chargeable cells when they are completed discharged is
applicable to NC (nickel cadmium) or NMH (nickel metal hydride) cells. This rule
does not apply to underwater lamps with high discharge currents, in this case, the
regular full discharge has a negative effect on the cells. The lithium manganese
cells used in this lamp do not have a memory effect.
Warning !
Regularly discharging a multi cell power pack may damage the voltage
