Camera/Battery Mystery Answered

I'm trying to solve a mystery with an old camera of mine(a kidak cx 7330). It showed a low battery indicator with a fresh set of batteries, as well as some older ones-so i assumed it was broken. Once i had it replaced (which was overdue anyway, its like, 5 years old), i popped in a set of rechargables which i got with the new camera, and it worked. i tried with another, not so fresh pair of energizers ... and it worked too.  (all batteries are AA- i prefer cameras that use em, since they arn't toyishly small)

Having gotten myself confused, i checked the voltages on all 3 sets of batteries. The fresh set was manganese, and 1.7v. The rechargables (nimh) were 1.4V and the not so fresh pair of energizers(alkaline) was 1.6 v and both worked. I'm wondering (other than what the hell is going on), if electronics have some kinda overvoltage protection, and if that was what was triggering off the issues, and if i ran down the manganese batteries to 1.6v or below, i could use them - that way i'd just use em for something high drain, and switch to them once its done.

i'd have to have a load to do that, right? hmm, that would mean digging out the old lab resistors i have lying around here, and the crocodile clips ;p

.  The battery contacts could have been dirty and removing/replacing the batteries may have eventually wiped the contacts clean. Wild guess.

The very first thing i tried was cleaning the contacts. Switching from rechargeables or energizers to overvolted new batteries resulted in the system not working
