    Good afternoon all lm a new user ,I have a 49 metre string of Fairy Led Lights that get their power via an intergrated Solar Supply.
    My issue is that the solar pack is not Charging the rechargeable batteries .
    Can I replace this with a power pack supplying similar output .
    Unit itself take 3 x 1.2volt batteries.
    It also has an 8 function control as part of unit Im not worried about retaining this as all I want to do is get them working .

    Regards Allan

    Canada, of course!
    The current through the LEDs must be limited with a resistance. Assuming the LEDs are all in parallel then the battery or the circuit limits the current. The LEDs will burn out if you use a power supply without limiting the current.

    I suspect that the rechargeable batteries are cheap junk. Try replacing them with better ones after cleaning the contacts in the battery holder. The on-off switch also might be cheap junk.
