the dcd950 is can use 18V XRP battery also used dc9180 li-ion battery,thanks

The premium packs (XRP) now offer Sony and Samsung cells, the updated circuits also includes fade; this is similar to NiCd where you can determine when the battery voltage is low, on the XRP Li-ion, the circuit cuts the voltage so you have a gradual shut down rather than a hard shut down.  The DC9181 launched with Sony cells

how gradual of a shutdown?  why would they do this?  i want full power until the battery is dead. 
i hope dewalt doesnt do the same to the 36 volt batteries.

I think all Nicads lose power as they die and lithium ion gives you a consistent power band right till the end.

It is just an indication that the battery will need to be charged, so it is not a long drawn out slowdown like NiCd.  36v stays the way it is........

I really like the lithium ion batteries preformance over ni-cad and ni-hi batteries. Please consider (2) batteries when offering your products. The consumer is looking for preformance, quality, usefulness, and then price in today's economy.

I am a little confused about that statement.  What do you mean by (2) batteries?  Do you mean that they should package 2 batteries with tools?  If that is the case, the majority os toosl sold with batteries do in fact come with two, the saws and grinder are exceptions to that of course.

As to Li-on vs. NiCad, everyone has their opinion.  The reality is that there are definite benefits to both chemistries, and that the deciding factor should be the intended use for the tool.  If you are gonig to be working in extreme temperature conditions, or work your tools extremely hard, go with NiCad.  If you are working in more "normal" conditions, go Li-on.  Honestly they are both great, and I have lots of each so that I can plug the appropriate battery into any of my 18v tools to fit my use for any given day.

I was also skeptical about the artificial draw down on the Li-on batteries, as I do not want to lose power when I don't have to.  Having used this feature now hwoever, it is actually really nice.  It only affectsyour last screw or two, and just slows down the speed a little bit, so you know to chnage the pack.

I guess it made a believer out of you

You are talking about DC9180 and DC9181.

But on my batteries it says DE9180. What is the diferent. I´ve the nano symbol and it was advertised to be able to recharge 2000 times.

Maybee it is written DE on batteries sold in europe and DC on batteries sold in the states. I bought my machine in Sweden.

And how much performance is expected to be left after 2000 cycles? !00 percent or maybee just 50 percent. Or is it going to downgrade after 2000 cycles?

DC9180, the compact battery (DC9181) do not have that particular software

But on my batteries it says DE9180. What is the diferent. I´ve the nano symbol and it was advertised to be able to recharge 2000 times.

The DC/DE9180 batteries with yellow side labels have the fade software

Maybee it is written DE on batteries sold in europe and DC on batteries sold in the states. I bought my machine in Sweden.

Yes, there is no difference, just the labels

And how much performance is expected to be left after 2000 cycles? !00 percent or maybee just 50 percent. Or is it going to downgrade after 2000 cycles?

The 2000 charge cycles is a cell manufacture spec if i am not mistaken, so use the battery for what it's intended purpose is.

One more interesting thing that I do not think anyone have asked before about. Dewalt and makita just to name a few claims their li-ion battery will charge upp to 2000 cycles. But what is really a cycle? They say no memory effect so you can charge them when ever you like to. That´s fine but if you for example charge your battery 10 times and thay are only drained for example 1/3 of a full charge. Will this shorten the battery 10 charges of it cycle life or only 3 charges?

Personaly I only charge them when the battery is empty, do not se any point to put the battery on the charger after a couples of holes drilled. But I think you can see my point. If you have a habit to put the battery on the charger very often ( because no memory effect ) when not needed to, will you be able to have the whole RUNTIME from your batteries?

Good question, the charge cycles comes from the cell manufacture and that is the industry standard (i am not an electrical engineer or have any advance knowlege of cell cycle times so dont quote me on this) from what i understand is, charge cycle is a cell that is charged to norminal capacity and then discharged under minimal load to it's low voltage cutoff limits; this would be one charge cycle, when a cell is discharged under heavy load the amount of maximum charge cycle decreases.  I will try and get more information on this subject but the quickest way would be to google the topic

I just ordered 4 new DC9180 Li-Ion off internet.  Only used DC9096 NiCd before.  Does the Li-Ion stay on the charger 24/7 when not in use also?  What is the Ah of the nexer version?  What does 'sleep mode' do exactly & does it automatically come out of that mode when placed in a charger?  When did Dewalt use NiMh batteries, maybe the first cordless tool kind?

I found this article interesting, it talks about Dewalt Li-Ion being more safe then standard ones:

Sweet!

The DC9180 CAN stay on the charger 24/7, however being a lithium battery their really is no point to leave them on the charger because they won't discharge nearly as quick as a NiCd.

ah on the DC9180 is 2.2ah

Sleep mode prevents the battery from discharging itself further. They batteries are not shipped charged, and need to be protected from a potentially long shelf life before being used. Once a lithium batteries drops below it's critical discharge level, it can't be brought back. People who completely discharge their lithium batteries, and never re-charge them for a long period of time, usually ruin a perfectly good battery.

NiMh are still in use in Europe, and were in the USA a long time ago. I believe Europe banned the use of NiCd cells. Hence the reason they are not in use over there. However, I could be wrong.

Wartex used to be a member on this site. He was a great source for all things batteries. He sorta fell of the planet the last year.

I know that on NiCad batteries the first hour in the charger it charges, then the next 8 hours it does a tune up mode.  Does the Li-Ion do the same tune up mode?
