I have this trimmer/edger which here in the east is most likely going
to be utilized for the Summer only. In the remaining 10 months, what
happens by non usage with the rechargeable battery? The company says,
run it down at least on a monthly basis, which I feel is ridiculous .
Its one of those Li-Lon batteries..18volts Anyone here in a similar
situation and found the solution?
In general batteries like it cool or cold, as long as they don't freeze. Some
don't mind freezing, either. Likewise high temperatures are death on
batteries. Keeping them in the garage in the summer is not a good idea. I
make sure all the batteries for my cordless tools are stored in the house.
the battery pack has a limited number of recharges,and unnecessarily
discharging it and recharging means you need to buy more batteries.
Li-ion batteries are noted for their good charge retention in long-term
storage.(low self-discharge rate)
Instead of "cold" storage,I would just avoid HOT storage places,like
garages without AC. Of course,we in the northern hemisphere are now getting
into the cooler seasons.
Google LiIon battery maintenance, I think you will find it might take
a few charges in 10 months to recover, but I would not go to the
trouble of discharging it every month and wearing out the motor. I
dont go to that trouble with phones, laptop computers, my video and
regular camera and none of those state to do so.
They are all LiIon so there has to be some similarity,we are not
talking Nicad or Lead Acid so these recomendations to me mean
something. What I read heat and overcharging is bad, mainly heat. Sony
for Liion just says to store them at about 75% charge, Popular
Mechanics magazine has a new article today on LiIon battery
maintenance. Cycling them as his trimmer co says just sounds wrong for

Those batteries have a finite lifetime deemed by the number of charge/
discharge cycles and age. It makes no sense to drain and charge the
battery when you don't need to. I own a ham radio miniature hand held
walkie talkie. This thing is an Alinco DJ-C4 if you want to google it.
It has a Li-ON battery inside that has not been charged for 10 years
but it will still power the unit. That may or may not be of some
relevance to you.
