 OPERATING INSTRUCTIONS

Version 04/09

UNIVERSAL CHARGER P-600 LCD

Item No.  20 26 00

INTENDED USE

1. 

The charger is intended to charge or discharge one to four NiMH rechargeable batteries of types AAA / AA / C / 
D. It can also charge one or two 9V-block batteries. One USB device can also be charged separately. 
The charger integrates the minus delta voltage (-∆V) function, which monitors the voltage over the charging 
cycle. When the battery pack is fully charged, the charger will begin a trickle charging automatically, to keep 
the battery at its optimum capacity level. The charger has short-circuit, overload, wrong polarity and wrong 
polarity detection function. 
The charger is powered by 100-240V~ / 50 or 60Hz mains outlet. Only operate the charger in a dry, indoor 
environment. Do not expose it to moisture.

This product fulfils European and national requirements related to electromagnetic compatibility (EMC). 
CE conformity has been verified and the relevant statements and documents have been deposited at 

the manufacturer.

Unauthorised conversion and/or modification of the device are inadmissible because of safety and approval 
reasons (CE). Any usage other than described above is not permitted and can damage the product and lead to 
associated risks such as short-circuit, fire, electric shock, etc. Please read the operating instructions thoroughly 
and keep them for further reference.

• 

Product safety

Remove charger from mains outlet when it is not in use.

• 

There are no serviceable parts inside the device, therefore, never disassemble the device.  

• 

There is a risk of fatal electric shock when touching electric components. Capacitors inside the 
unit may carry voltage even if it has been separated from all voltage sources.
The insulation, including the housing and the mains cable, must not be damaged.

Battery safety

This charger is intended for Ni-MH rechargeable batteries only. Attempting to charge other 

• 

types of batteries may cause personal injury or damage to the charger.
Do not charge non-rechargeable batteries.

• 

The manufacturer’s instructions for the respective batteries must be observed, before they 

• 

are charged.
Correct polarity must be observed while inserting the batteries.

• 

Batteries  should  be  removed  from  the  device  if  it  is  not  used  for  a  long  period  of  time  to 

• 

avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in 
contact with skin, therefore use suitable protective gloves to handle corrupted batteries.
Batteries must be kept out of reach of children. Do not leave the battery lying around, as there 

• 

is risk, that children or pets swallow it.
All the batteries should be replaced at the same time. Mixing old and new batteries in the 

• 

device can lead to battery leakage and device damage.
Batteries  must  not  be  dismantled,  short-circuited  or  thrown  into  fire.  Never  recharge  non-

• 

rechargeable batteries. There is a risk of explosion!

Miscellaneous

Repair works must only be carried out by a specialist/ specialist workshop.

for type AAA / AA / C / D batteries

Only charge batteries of the same type, size and capacity at one time. 

You may charge up to four rechargeable batteries of either one type of AAA, AA, C or D. 

1. 

Press the release button (2) to open the cover.

2. 

Pull back the negative terminal (6) before inserting the rechargeable battery into the compartment. Ensure 

3. 

that the correct polarity is observed.
The  rechargeable  batteries  do  not  have  to  be  inserted  simultaneously  since  the  charging  processes  are 

4. 

independent of each other.
The charging process will automatically start once the battery is inserted properly.

5. 

During charging, the LCD displays “CHARGE” with a permanent blue backlight. 

6. 

Once the batteries are fully charged, the LCD displays “FULL” to indicate that the batteries are ready for use. 

7. 

The charger will then automatically switch to trickle charging. 

8. 

The blue LCD will turn off when trickle charging completes. 

9. 

The trickle charging current and time is as follows:

The  trickle  charge  function  prevents  the  rechargeable  batteries  from  being  overcharged  and 
compensates for self-discharging of the rechargeable batteries. Each rechargeable battery will be 
individually charged up to its maximum capacity. 

for 9V block battery

9V block has charging processes independent of the four charging compartments. You may charge 
up to four AAA or AA batteries with two 9V blocks. 
Type C or D batteries cannot be charged with 9V blocks due to physical limitations. 

Press the release button to open the cover.

1. 

Insert one or two 9V rechargeable batteries to the battery connectors (1). 9V battery connectors are designed 

2. 

to avoid wrong polarity by allowing only one possible configuration. Do not insert the batteries by force.
Two 9V block rechargeable batteries can be charged simultaneously.

3. 

Once the batteries are fully charged, the LCD displays “FULL” to indicate that the batteries are ready for use. 

4. 

There is no trickle-charging for 9V block batteries. Remove them once they are fully charged.

5. 

Charging time

Determine the your battery type and capacity to find the charging time.  
The safety cut-off timer will automatically cut off charging to prevent overcharge.
