Hi All!
I hope this note finds all of you well & enjoying today!
In our home we have a battery powered stick vacuum broom gizmo. It is used perhaps once a month.
We run it until the motor slows noticeably, then put it on the charger for about 16 hours before unplugging it. But, when one of us decides to use it, the battery pack is depleted. I believe this is due to NiCad battery characteristic self-discharging.
I replaced the cells recently & have a question about proper charging procedure for a seldom used item. From my general on-line research, much conflicting information was read.
The cells are:
Quantity of (5) 2200 mAh 1.2 volt Nickel Cadmium sub-c cells wired in series.
The charger is:
9 volt DC 1t 150 mA. It is a plain "wall wart" looking charger. I do not believe it has any specific charge level sensing circuitry, as there are only two wires to the battery pack.
My best guess of how to properly treat these cells and still have the machine available when needed is to:
1) Run the machine until the motor slows noticeably, but not totally off.
2) Charge for about 16 hours
3) Then move the charger to a timer which will charge for 1 to 2 hours a day (In order to replace what depletes from the battery)
But, for convenience, will it be OK to simply leave the machine connected to the trickle charger constantly?
What do you all think is the best way to treat these cells?
Thank You For Helping & Educating!
