I have a Spectra laser. The batteries were rechargeable 4 D and were original until I replaced them with some more common Duracells. I don't know if my charger is broken or the original batteries were bad.

Do the batteries have to be "rechargeable" for this application to recharge?
Will any 6 volt output charger work for this application if my factory charger failed?

Looking at something like this for a charger, assuming my original is bad.

Do not attempt to recharge "common" alkaline batteries , they are not made to recharge and cam explode if recharged.

Your charger may be designed for a certain type of rechargeable battery, Ni-cad, Ni mh or Li ion Make sure the replacement batteries are the same type and capacity as the originals. Those power supplies are designed to run a device, not recharge batteries, so good chance you need the correct factory charger or at least one designed to charge the size and type battery you use outside of the device.
