Lots of people ask me questions about these new li-ion 18v xrp dewalt batteries and li-ion tool bases so i hope i can help answer some questions for my customers here.
We`re going to have a quick look at dewalt 18v tool bases and i`ll try to briefly explain the 18v system with the li-ion batteries and what tools can be used with what batteries and what the phrase “nano or li-ion base” means. If your looking for info about the new 20v max xr slide type batteries there`s a separate guide for those. See our other guides for that.
Ok well where to start, basically all 18v xrp dewalt batteries will fit into and operate any dewalt 18v xrp tool. I`ll say this first up the type of base makes no difference and is purely a cosmetic thing and matters only as far as looks goes and not function.
The branding dewalt first used “nano” which is short for “nano phosphate” (this is dewalts own type of battery chemistry the a123 li-ion cell, developed by dewalt which uses nano phosphate rather than cobalt like most other batteries) this branding didn`t go down well with customers and created a fair bit of customer confusion. But basically old batteries can be used in new tools too and vice versa. The branding has since been changed and now they call them “xrp li-ion.”
It probably wouldn`t have taken a genius to figure that was a better name than “nano” in the first place you`d think. To me it seemed a fairly obvious choice…..
I don`t know what they do in the marketing department at the moment but they make strange choices. Dewalt currently produce a whole stack of tools that are all the same now too but have different models numbers according to what battery comes with the tool, just to confuse the people who arn`t already confused. Like dc825, dcf826, dc827, all 3 of those tools are identical 1/4″ impact drivers, identical in every way except the sticker, but all 3 have different model numbers with a different sticker on the side of the tool. But there`s more about those in another guide because that`s a whole different story.
But anyway back on topic,
A li-ion dewalt battery will fit any 18 v dewalt tool but it will not charge in a ni-cd charger and needs a li-ion charger to be recharged.
Xrp – ni-cd batteries can be charged in li-ion chargers.
The base of the tools has changed slightly in shape only and with the swap to li-ion it has brought a re-design in the tool base where the battery connects and this is where people get confused. The top of the batteries are essentially the same. both types of bases the li-ion “nano”base and the older xrp base will fit both types of batteries.
it`s just a neatness thing and the new base fits the outside of a li-ion battery better than the xrp base did which looks a little silly with a li-ion battery pack installed. But it still functions perfectly well.
PICTURES SAY A THOUSAND WORDS.
SIDE BY SIDE LI-ION BASE VERSUS AN XRP BASE IT`S EASY TO PICK THE DIFFERENCE, ONCE YOU KNOW WHAT YOUR MEANT TO BE LOOKING AT. ALMOST ALL THE DEWALT TOOLS ARE NOW MADE WITH A LI-ION BASE.
IT`S A PURELY COSMETIC THING AND NOTHING MUCH TO BE WORRIED ABOUT AND CERTAINLY NOT WORTH REPLACING A TOOL OVER IT.
So as you can see where my finger is pointing too in the pictures above, a li-ion battery doesn`t fit well at the base of the tool and vice versa for an xrp battery on a li-ion based tool. The edges of the tool base poke out or the edge of the xrp ni-cd battery poke out. One or the other.
But they both still operate the tool perfectly well and as i said it`s a cosmetic thing. So no need to be running out replacing your old xrp tools with a nano based / li-ion based tool thinking your getting something special. The tool will not do a better job in any way, shape or form, it will simply look a little better. If you were intending on using xrp packs then your old tool would actually fit better.
Note: for tools such as the dc411 grinder, dc212 sds hammer and other high load tools like saws the xrp ni-cd battery will probably last longer too. The li-ion batteries take damage at 50 degrees, the older ni-cd`s at 70 degrees +. So generally speaking in tools that discharge batteries really fast under load and for guys who work tools and batteries hard the older ni-cd will outlast a li-ion battery. There`s another guide about li-ion batteries i`ve written if you want more info on those the link is on the right side of this page.
Basically working an xrp ni-cd battery really hard in a tool usually won`t effect it`s lifespan at all since it`s hard to over heat them. Generally speaking working a li-ion battery hard in a tool and doing fast discharges and full cycle recharges repetitively will effectively cut a li-ion batteries lifespan in half.
SO TO SUM UP,
All 18v dewalt batteries both li-ion and ni-cd fit all the 18v tools, they just dont match the base quite as well if it`s the wrong base.
But they still fit and operate any 18v tool perfectly well.
Li-ion batteries need to be charged in a li-ion battery charger and won`t charge or fit into a ni-cd charger.
Li-ion chargers will charge ni-cd batteries too.
So if you getting li-ion batteries you can use them in all your tools you just need a new charger.
Dc9310 suits and is what is shown above. Also dc9315 & dc9319 can be used for li-ion.
You can`t use the de9116 to charge li-ion batteries it`s a ni-cd charger.
I hope that helps you out.
Please remember to vote, just click yes to vote it helps more people have access to this information easy. It also lets me know people actually read it. Which means i`ll keep writing more guides since they help people out. Voting only takes one second, one click.
I hope the guide wasn`t too boring but it`s hard to explain properly in any less space.
UNTIL NEXT TIME TAKE CARE AND ALL THE BEST.
