I have got hold of 2 old V5535 (Z17M2.0) and refurbished them for my parents to use.
The batteries had failed on both so need replacing.
1 battery removed was 11.1v and the other was 14.8v ! (don't which one came from which)
What is the correct voltage battery that I need to buy ?
The serial numbers are YKDA218079 and YKDA663531.
Can some one please confirm the correct batteries I need ?
