If I figure out what to do before getting my answer, I'll be sure to share the info with Battery University.
Because of similarities within systems, the chemistries are limited to lead, nickel and lithium. An equalizing charge prevents battery stratification and reduces sulfation, the leading cause of battery failure. higher mAh) battery instead of the lower one. Upon inspection of the batteries we found formation of white powder at the bottom of the plastic casing.

Revive Lithium Ion Battery Yes, for high drain applications Duracell Ultra and Energizer Advanced Formula batteries do last longer than standard alkalines. How To Awaken Sleeping Li-ion - Battery This would mean drawingin a lot of current from the charger and it could be an adaptor or such equipment which is never good.
Thank you so much! That's it. Do not over-discharge on a heavy load; cell reversal causes short. Most cordless phones use NiCad batteries. How To Fix A Dead Laptop Battery
Copper shunts may have formed inside the cells that can lead to a partial or total electrical short. It's important to remember the aging characteristic when purchasing batteries. Battery University monitors the comments and understands the importance of expressing perspectives and opinions in a shared forum. What will be the internal resistance of that battery at -40°C ?
