Background information about NC-Akkumulatoren

Nickel Cadmium and Nickel Metal Hydride cells are generally accepted as being gas tight. It is for this reason that the cells can be charged in any relative position as no electrolyte will leak from the cells.

However, no manufacturer that we know of will guarantee this feature for the entire expected life of the cells! An over-pressure may be produced during the charge or discharge cycles, which may open the integral pressure relief valve.

This means that electrolyte or hydrogen gas may escape from the cells. The electrolyte is an aggressive alkaline and it conducts electricity, this may result in damage of the cells due to electrolytic corrosion.
The leaking hydrogen gas will combine with oxygen in the atmosphere and produce a highly explosive mixture. The dangers resulting from such a reaction are obvious to all. A cell the size of a standard D battery can produce up to 25 litres (approx. 1 cu. ft.) of gas. The consequences of this in a small enclosed housing are easy to imagine.

For this reason, it is important that the cell packs are removed from the housing during the charging cycle.

A safe life expectancy of the cells can then be assured. The so called Memory Effect is the common term for the reduction in the capacity of the cells as a result of charging the cells in a partially discharged condition. (e.g. A wireless telephone handset has a battery life of 24 hours, but is replaced on the station and therefore charged after
3 hours).

The common technique for overcoming this is to fully discharge the cells before charging. We regard this as being more harmful for underwater lamps with between 5 and 20 cells.

The constant discharge down to the cut-off voltage limit can overload individual cells and disrupt the balance within the matched cell pack.

This may result in an individual cell "dropping out". We recommend that for every 10 to 20 cycles where the cells are partially discharged, that the lamp is fully discharged until the built in discharge protection turns the lamp off.

The more often the cells are taken to their minimum capacity, the higher the strain on the individual cells.


 


 


 

 

Charging Nickel-Cadmium and Nickel-Metal-Hydride Cells is a science in itself.

Incompatible chargers will have a detrimental effect on the life expectancy of the cells.
In addition to this, there is the danger of the cells producing a detonating gas (Oxyhydride).
With some generic chargers, the rated capacity of the cells may not be reached.
The Hartenberger Chargers are developed and manufactured by a company specialising in charger technology and are specifically designed to suit our equipment.


 



Hartenberger Unterwassertechnische Geräte GmbH - Ladegerät 125/128 standard
 

LG 125/128 standard
(Supplied as standard charger with all 12V/ 5Ah and 8Ah Cell Packs, Lamps and Power Packs)

The input voltage is 115/230V +/- 10%.
A Red LED light indicates the correct charge is taking place.
The charging process is completed within 14-16 hours.

During the charging process, the charge current is calculated and controlled so that even partially discharged cells can be charged without cause for concern.
The high quality cells used in Hartenberger products, tolerate an overcharge for several hours without any loss of capacity.
The excess energy produced is converted into heat and as a result of the housing construction, is then dissipated into the surrounding medium.

Ladegeräte mini stab. und
medi stab. / mini compact

LG mini tube and LG medi tube/LG mini compact
(Supplied as standard charger with all tube lamps, Set Cave medi and with the mini compact hand lamp).

The input voltage is 115/230V +/- 10%.
A Red LED light indicates the correct charge is taking place.
The charging process is completed within 6 hours for the tube lamp mini and within 8 hours for the tube lamp medi.

During the charging process, the charge current is calculated and controlled so that even partially discharged cells can be charged without cause for concern. The charger switches automatically to a pulse trickle charge.

LED lights indicate the state of charge.


 








Hartenberger Unterwassertechnische Geräte GmbH - Ladegerät off-shore I/6 - Ladegerät off-shore I/12

 

Ladegerät off-shore I/6
Ladegerät off-shore I/12

LG off-shore I/6 and LG off-shore I/12
Supplied as standard charger with maxi compact, Set Wreck maxi , Set Video maxi (Optional for all of our underwater lamps).

This charger utilises the most modern electronic technology with a universal input voltage automatically adjusting to mains voltages between 100V and 250V !! (It is not necessary to switch manually between different input voltages).

The off-shore I/6 charger is designed for all cell packs with 5 and 6 Cells (Nickel-Cadmium and Nickel-Metal-Hydride).
The maximum charging current
is 1.1 Amperes

The off-shore I/12 charger is designed for all cell packs with 10 and 12 Cells (Nickel-Cadmium and Nickel-Metal-Hydride).
The maximum charging current
is 1.0 Amperes

The charger continuously monitors the charging process and calculates an optimal charging curve. This calculation takes place during the intervals between pulses. The monitoring guarantees a very gentle cell charging process. When the cells are fully charged, the charger switches automatically to a pulse trickle charge.
The charger is protected against strong input voltage fluctuations and increased environment temperatures by electronic protection devices.
All the functions of the charger are displayed via the LED lights.

The maximum charge times for discharged cells are as follows:

  • 1.8 Ah approx. 2 hours
  • 4.1 Ah approx. 4.5 hours.

If the cells are only partially discharged, the charge time will be reduced.
The charger weighs only 200 Grams. (approx. 7 oz) The patented Plug Adapter System for the most common sockets, allows it’s use all over the world possible.


 



Hartenberger Unterwassertechnische Geräte GmbH - Ladegrät off-shore II










 

Ladegerät off-shore II
Supplied as standard charger with Flash 250/625 TTL digital
(Optional for all of our underwater lamps).

The off-shore II charger is one of the smallest, most powerful and universal chargers available on the market. The features are similar in most points to the off-shore I charger except that it is 4 times more powerful.
The maximum charging current is 1.8A.
In addition to this, the charger automatically recognises all of our cell packs with between 5 and 12 Cells (Nickel-Cadmium and Nickel-Metal-Hydride). After identifying the unit, a charge process is calculated and the cells are charged in the shortest time possible. All the functions of the charger are displayed via the 2 LED lights.

The charge times for discharged cells are as follows:

  • 1.8 Ah approx. 1 hour
  • 4.5 Ah approx. 3 hours
  • 5.0 Ah approx. 3.5 hours
  • 8.0 Ah approx. 5 hours


Despite the enormous power and performance this charger offers, it weighs a mere 200 Grams (approx. 7 oz) and is hardly larger that a pack of cigarettes!
