I had a question for the battery experts here.
I recently replaced all the AAA and AA batteries in all the remotes and other devices around the house with NiMH rechargeable cells. I did this after an alkaleak almost ruined an expensive remote, probably the fifth or sixth time I've seen one leak in the past 5 years. So I got sick of the alkaleaks and replaced all of them. Now I have about 75 of these alkalines, most of which are at 70 to 100% of capacity that I don't know what to do with.
We have an older Panasonic cordless phone with five handsets, and I don't care if it gets ruined as I'll just buy a new one at Costco. So I installed the alkaleaks. They work fine, but the handsets came with Panasonic NiMH AAA batteries which are now doing other duty.
So here's my question. The charge indicator on the handset says the phone is only 25% charged. I was surprised by this since alkalines are 1.5V and NiMH are only 1.2V. The handsets work fine with the alkaleaks (I wasn't worried about the extra 0.3V stressing the circuitry) and as long as I don't forget and put one of the handsets back in its charging cradle and try to recharge a primary all should be well. I just don't understand the state of charge indicator only showing 25% since they were all replaced with alkalines showing 90% to 100% capacity.
