7. Notes on Batteries and Rechargeable Batteries
Operation of the outdoor sensor of the weather station with rechargeable batteries is
generally possible.
The lower voltage of rechargeable batteries (rechargeable battery = 1.2 V, battery =
1.5 V) and the lower capacity, however, leads to a shorter operating duration and may
reduce the radio range. Moreover, the rechargeable batteries are more cold-sensitive
than batteries.
If you want to use rechargeable batteries in spite of these limitations, always use
special NiMH batteries with a low self-discharge.
We recommend that you use high-quality alkaline batteries to ensure long and safe
operation.
The weather station requires 3 batteries of the type AA/Mignon; the outdoor sensor
requires 2 batteries of the type AAA/Micro.
• Keep batteries/rechargeable batteries out of the reach of children.
• Ensure that the polarity is correct when inserting the batteries/rechargeable batteries
(observe plus/+ and minus/-).
• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of
batteries being swallowed by children or pets. If swallowed, consult a doctor immediately.
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin at
contact; therefore, use suitable protective gloves.
• Make sure that batteries/rechargeable batteries are not short-circuited, disassembled or
thrown into fire. There is a danger of explosion!
• Do not recharge normal, non-rechargeable batteries. There is a danger of explosion! Only
charge rechargeable batteries which are intended for this purpose; use a suitable battery
charger.
• If not used for a longer period (e.g. in case of storage), remove the inserted batteries/
rechargeable batteries. There is a danger of old batteries/rechargeable batteries leaking,
which causes damage to the product, loss of warranty/guarantee!
• Always replace the entire set of batteries/rechargeable batteries, only use batteries/
rechargeable batteries of the same type and by the same manufacturer with the same charge
status (do not mix charged with partially charged or empty batteries/rechargeable batteries).
• Never mix batteries and rechargeable batteries. Either use batteries or rechargeable
batteries.
• For proper disposal of batteries and rechargeable batteries, please read the chapter
“Disposal”.
