Is there a rechargeable solution equivalent to 3 LR44 batteries?

[NAW]

Hi guys,

I have a small keychain light that I had just tricked out with 3 5MM LEDs & it runs off of 3 LR44 coin cell batteries.

Is there any rechargeable solution that is like or even better than 3 LR44?

-thanks

I have a KeyMate ..... would love to know too !!

I wonder if a RCR2 (rechargeable CR2) would work? I never seen one in person but they look to be the same size. Can anyone confirm this?

the LR44's aren't capable of providing enough current under load to overdrive the LED's, but a Li-Ion cell probably is, unless the light uses a resistor to drop voltage

Hi chevro,

do you know of any battery(ies) that is the same size as 3 LR44s in series?

the closest I can think of is the 10180 that Modamag is using in his new "Drake"
