WHAT YOU SHOULD OBSERVE BEFORE FIRST COMMISSIONING !
When choosing your rechargeable batteries, ensure that they are suitable for fast charging. Particularly
older or very cheap batteries are often not admitted for this type of charging.
New rechargeable batteries
- The batteries supplied with the unit are already charged. You should charge all batteries first before
using them, since they discharge after a longer storage time.
- The maximum capacity of the rechargeable battery is only achieved after several charging/discharging
cycles.
What you should note in general when working with NiCd and NiMH batteries:
- Do not dispose batteries in domestic waste, but surrender them to a battery collecting point.
- Use nickel/metal-hydride (NiMH) rechargeable batteries instead of nickel/cadmium (NiCd) batteries, since NiCd
batteries contain environment-polluting and unhealthy heavy metals. NiMH batteries have a higher capacity and
thus longer operating times.
- Do not charge batteries in extreme cold or hot (> 40 °C) conditions.
- Always store a rechargeable battery in charged condition when the rechargeable battery is not used for a longer
period of time.
- After a longer time of non-use, recharge battery before use.
(NiMH batteries have a self-discharge of approx. 10 % per month when not used.)
