The BBC Master contains a CMOS battery - this is often forgotten and leads to leaks which can seriously damage the internal components of the system. This kit contains everything you will need to give your BBC Master a new battery: full colour instruction guide, battery holder with reverse-charge prevention & self-adhesive back, 3 x Brand-new alkaline batteries and a cable tie.
