Theses are old but work. I haven't used these and need the space. If I get time I will find the transformer and will.charge up batteries and figure out which work best. Please note I dont have a uk charger for these I used a transformer Thats probably why they have hung around for so long. I am Happy to split . I am going to the tip Thursday if there is no interest. If I can find it I may sell the transformer.
If you want to collect please let me know you understand the chargers have US plugs and need a transformer.
