I was in the process of rebuilding 5 82001A/B batttery packs this weekend and wondered if the replacement NiCads, which are rated for 700 milliamp-hours offer any improvement in operating time over the original ones. Does anyone know the ratings of the original AA NiCads?
I also have 2 batt packs from 1985 and one from 1989 that have not been used and appear to hold a charge like they were new. Is there any problem with using these or do the pose additional risk to the calculator because of their age. I am most worried aout leakge due to the early manufacture date.
And finally, will storing NiCads in the freezer when not in use prolong their life. I typically use 2 batteries and the other ones just sit on the shelf unused so I thought that perhaps they could be frozen when not used. Maybe this is a crazy idea but since the production of electricity in a battery is a chemical reaction it the colder temperature should slow down the self discharge but will this process prolong its useful life? Should the packs be frozen in a charged or discharged state?
Thanks in advance to your thoughts
