Cell C Adapter

[femiguel]

Is safe to use cell C-AA adapters? Cell C batteries are 1.2v and AA 1.5v
I want to buy a Princeton Shockwave LED but in my country (Brazil) cell c batteries are so expensive! And I have a lot of AA cells rechargeable.

Alkaline C and AA batteries are both 1.5 volts.

Rechargeable C and AA batteries about about 1.2 - 1.25 volts.

You can use a C -> AA adapter, however a AA cell won't last as long as the C cell.

The rechargeable AA batteries might not work in place of the C cell, however they shouldn't hurt anything. You will just get much shorter useful life between recharges.

Welcome to the board.
AA rechargables (NiMH) in C adapters work fine in led lights. The voltage on them is 1.25 instead of 1.5 for a C or standard AA but if you look at the voltage curve on on a alkaline AA it very quickly drops to 1.25v anyway and then continues to drop. NiMH batteries on the other hand start at 1.25v but stay close to that voltage through the entire useable capacity. While the capacity of a recharable AA is less than a C, with LED lights it pretty much become a non issue because of the low power drain of the LEDs as compaired to a standard bulb.

Thank you guys!
