If it is an adjustable one it *should* charge them, 14500 is one of the sizes commonly found in the listing of batteries that go on the multi chargers that I have that I use to charge my 18500 and 18650's. Looking at the numbers it looks more likely that it would under charge than over, but with random non-smart chargers like that the usual caveats apply. Do not charge unattended. Do not leave on the charger after it is finished charging, if it gets hot stop, etc. And test the voltage on your battery before use. If yours does not work, PM me and I can send you one of my spare basic chargers from either my bolt or my tox, as I have a smart charger that I use exclusively now. I KNOW those will charge.
