Hello all
December around the 21st last year I did have a question on charging a
rechargeable alkaline AA battery.
Using those 2 in my wireless optical mouse.
Normal battery did last 1 month
Alkaline battery did last 5 month,
Alkaline recharge battery 2.5 month, empty reading is 1 volt.
Started charging both batteries on 1.68 volt, the charging current was 110
mA per battery.
Charging current after 10 hour is 95 mA for both batteries, constant voltage
1.689 volt.
Hope this will help someone sometime.
Greetings
Bert.

And the number of spontaneous exploding charging cells is still
zero, I guess ?

No exploding cells, do check every hour or so that the voltage on the
battery stays below 1.7 volt and the battery is still cool to touch.
Remember it is a rechargeable AA alkaline cell.

My apologies.
I missed the part about the cell being 'rechargable Alkaline'.
