My M31 in VME head does not work with my 2AA body. It will if I put a brass washer in there. I don't care for that. Is there another way to make it work. Same thing with my older Malkoff MDC heads, like my TAC light. I don't want to be fumbling with a washer in the dark if I need to do a battery change at work. My 2AA is a farly newer version. It has the darkened clip. The inside of the body looks anodized. Thanks.
But this is where I am confused. Malkoff states on their site, DO NOT USE A RECHARGEABLE Li-ion CELL. The voltage is too high. for the MDC HA 1AA. So, won't the CR123 also exceed the voltage, being they are 3.7V nominal?
