9 Battery and Charger
9.1 Properties
Batteries are either integrated into the devices from mk messtechnik GmbH or delivered separately as external
battery packs.
The number of cells varies and depends on the required voltages.
The related charger has the following properties:
•
Power supply with power plug (Standard EU (type C or F) unless ordered otherwise, optional US (type A), UK
(type G), AU (type I))
•
Integrated LEDs to display the charging level of the connected devices respectively the connected battery
packs.
•
Short-circuit-proof, reverse polarity protected
•
Suitable for batteries with 4 … 10 cells and a capacity of 1,0 … 10,0 Ah
•
Charging process IUoU
Chargers with the charging process IUoU work basically identical to those using the IU (CCCV) charging process.
After reaching the end of charging voltage however, the device switches to trickle charging. This way a self-
discharge is avoided.
9.2 Regulations and References
Protect the batteries from heat (e.g. long exposure to direct sunlight) and fire. Do not immerse the batteries into
fluids. Otherwise there is a risk of explosions.
§
Risk of Damage and Explosion Because of Incorrect Treatment
Unintentional or incorrect treatment can damage the batteries, which can even lead to
explosion of the batteries!
Batteries that are integrated into the devices of mk messtechnik GmbH or are delivered with them, may only be
charged with the intended chargers from mk messtechnik GmbH.
These components are compatible to each other, other chargers may damage the system or may reduce the
capacity or life span of the batteries significantly.
Respect the following references when operating the chargers:
•
Use chargers only for charging devices and batteries.
•
Switch devices off before connecting the charger.
•
Do NOT switch on the device during the charging process.
•
Maximum charging current 1.2 A.
•
Disconnect charger before turning on the device.
•
Prior to first use, charge the batteries completely.
