My charger has died. No idea what it was, it came with my Solarforce torch. Fortunately no inferno, just doesn’t charge.
So what charger and where from? The 18650 batteries I have are protected, if that makes any difference. If it can do 26650 as well, that would be a plus point

Try Mtbbatteries

Nitecore Intellicharge i4 V2 or a Pila charger.

From here may I recommend:

Assuming that your batteries are individual ones?

+1 for mtbbatteries, he’s sorted me out twice.
