Instructions for use Hartenberger High-Tech-UW-Lamp nano compact

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
