When I store my cordless drill, should I remove the battery from it, leave it
on, or is it six to one, a half dozen to the other.

Why wear out the latches and contacts prematurely? If the switch works properly
the battery is isolated. FWIW, I vote for leaving it on.

Consult the manufacturer's recommendation. Most, IME, recommend leaving the
battery in the charger, provided the charger has the overcharge/overheat sensor
circuit.

I disagree - most cordless drills use NiCad batteries which have memories so
should be drained before they are charged. Leaving the battery in the
charger will result in it being frequently "topped up" by the charger as it
naturally discharges and will reduce it's life and the amount of charge it
will take.

Leave the battery in the drill until it is almost fully drained.

Except for the new Dewalts and Milwaukees. They have memory free batteries.
You can charge them whenever you want. However, it is still better to just
leave them on the tool and have the second ready to go. It only takes an
hour to fully charge a dead battery anyway, 45 minutes with the Milwaukee's
triple charger. As far as the other brands, you are correct, the NiCads
need to be fully drained before recharging or else they develop a memory and
will not be able to be fully charged.

Forgot that NiCads also do not loose their charge very quickly, as opposed
to the NMH that are memory free, but quickly loose their charge.

I've had a cordless 12v DeWalt drill since 1998 and I have always left
the battery on when not using it. In fact, the battery stays on until
it is drained. The spare battery always stays in the charger which is
plugged into the wall. Not sure if this is good or bad but it is what
I have done. No worries so far.

PS -- Still using the same 2 batteries that came with the drill and
I've used (and abused) the drill quite a bit for driving deck screws
and making holes.

Keeping it attached should not result in any drain, so it
doesn't make any difference if the pack is attached or not,
unless you have some light or electronic readout on all of
the time.

And the saying is six OF one and half a dozen OF the other.
The preposition TO doesn't make sense.

Seriously, leave them attached unless instruction for that
particular brand say otherwise. Even cheap batteries don't
discharge that rapidly. OTOH, the tendency for many home
owners is to ignore the batteries which sit for varying long
period and just die. Or, they let them sit, and then charge
them for long periods (forget them) and way over charge
them, damaging the battery pack. If you have a precise up
to date well controlled charger, you can just let them
charge, but most chargers are not that good. The best bet
is a maintenance program whereby you check the voltage of
the pack periodically and when it reaches a certain point
you recharge the pack.

Forget all the stuff people tell you about memory and
discharging the battery pack. You should never discharge
the pack below 1 V per cell or you are likely to damage it.
And a cycle is a cycle and a battery pack has only a certain
number of cycles in it, so don't every discharge just to
discharge; discharge because you are using it and don't let
it get hot. Remember; never less that 1V per cell. In
practice, that number should be much higher and could be as
high as 12V. When you tool is getting obviously getting
weak, check the voltage and that is the voltage that you
don't want to go below.

The biggest problem with battery pack is overcharging, heat
kills quickly. So if your instructions say to fully charge
in 4 hours, never charge more than that, and if you use the
tool only a little and want to recharge, recharge for only
an hour or so. Check the voltage after the pack sits unused
for several hours and charge some more if needed. A fully
charged 12V pack probably reads around 13.2 volts. Check
the battery pack every month and charge it. You should
charge about once a month if you don't have and accurate
trickle charger (and most aren't accurate). Good Luck, and
if you need more information just do a google search on
Battery Memory and only read the ones that are from
universities, Government (e.g., NASA), or battery
manufacturers. Good Luck.

Don't think I understand that. In storage, the pack
constantly loose voltage through internal discharge. My
understanding is that as they go below 1v per cell, the
weakest cell is likely to reverse polarity and that will
ruin the battery. I keep mine charge above 12v by checking
every 4-6 weeks and charging before they drop below 12v.

I do the same with my lead acid batteries and charge them to
12.7v and while in storage charge them whenever they drop to
12.5v and never let them drop below 12.2v.

If you are talking about a NiCad battery being stored for a month
or more it is best to leave it in a some what discharged state. 40% of
its full charge is usually recommended.

A combination of constantly topping it off and not using/discharging
it

A combination of constantly topping it off and not using/discharging

Forty percent of full charge puts it below 1V per cell,
which will result in a good chance that the weak cell will
reverse polarity. That will kill the pack or lead to early
death.
For example, a 12V pack that measures 13.2V at full charge
will measure 5.28V at 40% charge, which is extreme. I just
checked two pack and one read 13.05 and one read 13.11 after
sitting for at least 10 days. My packs don't lose enough
voltage to require a charge more often than once every 30-45
days. That is constant topping off. In any case, topping
off isn't destructive, it's overcharging

Topping off the battery, if you mean charging to its full
capacity but no more, isn't going to ruin a battery. In
fact, that is exactly what the best chargers do. And not
using/discharging it won't ruin it quickly either. Not
using it does ruin batteries if you mean leaving it alone
because when internal discharge goes below 1V per cell, a
cell is likely to reverse polarity. All of my reading and
my limited experience of nicads (about 10 years) indicate
that overcharging and deep discharging (anything below 8V
for a 12V pack) are the main culprits for ruining battery
packs. I've found that individual AA cells used in walkman
type tape machines that discharge to about 1.25 V and then
are removed and continue to discharge to less than 1 volt
have very short lifetimes and successful recharge cycles.
Good luck with your 5.28V storage of 12V packs.

on, or is it six to one, a half dozen to the other.
Keeping it attached should not result in any drain, so it
doesn't make any difference if the pack is attached or not,
unless you have some light or electronic readout on all of
the time.
And the saying is six OF one and half a dozen OF the other.
The preposition TO doesn't make sense.
Seriously, leave them attached unless instruction for that
particular brand say otherwise. Even cheap batteries don't
discharge that rapidly. OTOH, the tendency for many home
owners is to ignore the batteries which sit for varying long
period and just die. Or, they let them sit, and then charge
them for long periods (forget them) and way over charge
them, damaging the battery pack. If you have a precise up
to date well controlled charger, you can just let them
charge, but most chargers are not that good. The best bet
is a maintenance program whereby you check the voltage of
the pack periodically and when it reaches a certain point
you recharge the pack.
Regardless of the voltage, when the drill noticably looses power it is time
to recharge it. But again, follow manufacture's instructions. Forget that
"man" stuff and read the manual!
I agree, when it loses power it's time to charge, but I
check the voltage more to establish a minimum voltage when
the batteries are stored. What is "man" stuff? Some tools
come with little more than a list of parts and don't give
any useful instructions about battery charging. They are
often as useful as new car driver manuals that say "see the
dealer."

When I store my cordless drill, should I remove the battery from it, leave it
on, or is it six to one, a half dozen to the other.
The battery will loose some of its charge...it DOESN'T loose voltage,
btw...just by sitting. Removing it from the drill won't stop that
process. The proper thing to do is keep it in the charger if you
don't have a spare battery.

And leave WHAT on?

And its 'six one way...half dozen the other'.



Wishing you and yours a happy Thanksgiving season...

Voltage Reversal I thought couldnt happen till 0.1 volt , being severe
discharge. I have 20 yr old packs still operational . I store at apx
1v a cell .

Oh Trent! As the battery loses charge, it loses voltage.
It may not tell you the exact amp-hours left, but it pretty
well tells you the state of the charge, i.e, whether it is
90 percent, 80 percent, etc.

Leave the battery on the tool

No it isn't! It's six of one and half a dozen of the other.
