The Remote Battery Cord LX is only moderately useful. The camera itself works well in the cold, and the original two silver oxide S-76 batteries can easily be replaced by one lithium 3V that is less susceptible to cold soak failure.

A more persistent gripe of mine was that the LX should been provisioned for the metering to be powered by the MotorDrive LX NiCad Battery LX when it's attached (as did the Nikon F3 with it's motordrive). Neither does the remote battery cord work with the MDLX. If the camera batteries die while the MDLX is attached you have to remove it to get at them. This is a problem on long remote sets, as the midroll motordrive removal is a no-no for the likelihood of film fogging. The problem also crops up with dedicated flashes attached that keep the camera metering "live," such as any of the LX contemporary ones (160T, 200T, 280T). I've made my own plugs using flat ribbon cable that allows the MDLX to stay in place while AA's are swapped out remotely.

Another battery issue this reminds me of is that when the LX motordrive NiCad Battery charge is low, the camera won't fire until/unless the MDLX is switched off.

Interesting. Why would removing the motordrive mid-roll cause film fogging?

Because the motor drive has a rewind clutch, that goes through a removable cover in the LX's bottom plate directly into the film cartridge. If you remove the MD, you will have an open hole in the camera's bottom plate. In practice I never really had any light leaking through the hole, when for some reason I had to remove the MD - but it is a possibility against which Pentax warns in the manual.
