Replace your depleted Rotlicht battery by yourself!
This battery is only needed when the first battery gets old and no
longer fully charges. There is no point in buying a spare until you need
it. It is not possible to change the battery quickly enough to use as a
substitute for recharging a good battery that has drained from use.
battery can be replaced by yourself. Simply remove the 4 small
Phillips screws, extract battery and disconnect wire, and replace.
