10.1 Maintenance
10.1.1 Replacing the Batteries
The batteries must be replaced when they no longer charge properly and this adversely affects the
operation of the Sunny Beam.
NOTICE!
Risk of damage to the Sunny Beam due to unsuitable batteries or batteries with
different states of charge.
• Do not use non-rechargeable batteries under any circumstances.
• Batteries of the wrong type may leak into the Sunny Beam. You must only use
rechargeable nickel-metal hydride batteries (NiMH), type Mignon (AA) with low self-
discharge, e.g. Eneloop batteries (see section 14 "Accessories" (page 86)).
• Batteries with different states of charge damage the Sunny Beam. Always use and
replace the batteries in pairs.
