DeWalt has a new cordless saw, the Model DC300K, that seems to promise
a major break through in battery life. The battery, apparently a next
generation lithium ion battery uses partials that are 100 times smaller than
the typical lithium ion battery. The M1 Nanophosphate battery has a
recharge time of a few minutes and is suppose to last 10 years.
Apparently this battery is being looked at to also power an automobile. The
recharge time to 80% capacity on an automobile is said to be about 15
minutes.
Here is what is posted on there website
First the charger:
Features: 1 hour charging provides fast charging for minimum downtime
Battery fuel gauge indicates how much charge is in the battery
DEWALT® 3-stage charging system provides maximum run-time and extends
overall life of the battery
Cord wrap provides improved cord storage
Then the battery
Features: DEWALT® exclusive nano-phosphate lithium ion cells provide
high power for corded performance; deliver 2-3x more run-time vs. 18V; offer
long battery life & durability: 2,000 recharges
Lightweight design- 2.4 lbs; same weight as an 18V battery
No memory & virtually no self-discharge for maximum productivity
& less downtime
The recharge time is the same as everyone elses. However the
charges over the life of the battery seems low. Milwaukee is warranting
their 28V and 18V LiON batteries for 5years/5,000 charges.

I guess if I was very clever, I would just rebuild my older cordless drill
batteries. The newer drills do not seem to have the durability of the older
PC units. I have a Panasonic unit. I bet my PC when new could have beaten
the pants of what is out there new. A set of new batteries for my old PC
was MORE than the new Panasonic with batteries. Oh well.

My first Panasonic, a 9.6 with Nicad didn't last long, the battery that is.
Couple of years maybe. At that point I bought my second one, a 12V with 2x3 Ah
NiMH and had the 9.6 repacked with NiMH also. That trio has lasted me somewhere
around the 6-7 years mark, but over the last few months they have faded badly.
So now I am getting the two 12V ones repacked, and I've replaced the 9.6 (sweet
machine as it is) with a 10.6 V Bosh driver, that comes with a couple of Li-Ion
accus. As yet no idea how that will hold up; obviously - I haven't even used it
in a work situation yet.
I think NiCad is ok in a high usage area but if you intermittently don't use
the appliance for weeks or even months they seem to die fast. NiMH don't do
that, but they lose their charge fairly steadily; initially over 3-4 months,
right now over about 1 week. Looking forward to finding out how the LiION will
hold up by comparison. A 2000 recharge lifecycle (as quoted by someone else on
the thread) would be just fine by me, cause it would translate into a 20+ year
lifespan :-)

Charges in a few minutes and lasts ten years??
I guess you wouldn't need a charger for this, would you?
I know, I will keep my day job.
