Cheap DeWalt DC9180-2-C (2) 18V NANO Lithium-Ion Batteries w/ DC9310 7.2V - 18V Ni-Cd / Ni-MH / NANO Lithium-Ion 1-Hour Battery Charger

DeWALT, once again, is not telling the whole truth about it's product. (But really, no power tool manufacturer is being completely honest about Li-Ion technology.) DeWALT boasts 2000+ charges for this battery, which sounds great on the surface. However, if you explore the technology or use the technology you will find that Li-Ion batteries must be charged much more frequently, almost twice as often as DeWALT's NiCd XRP batteries. With some research, I found that, basically, the same amount of energy is stored inside most Li-Ion and NiCd or NiMh batteries. The trick with Li-Ion technology is that it's much lighter than NiCd stuff. However, Li-Ion stuff requires internal circuitry to maintain proper use and storage and keep the battery safe and cool. The extra circuitry and other hardware adds weight to Li-Ion batteries. What does this mean? It means that if you compare apples to apples, this is how it comes out with DeWALT 18 volt XRP batteries: NiCd batteries can do more work on a single charge than Li-Ion batteries. DeWALT NiCd XRP batteries cost about 1/2 as much as DeWALT Li-Ion batteries. DeWALT NiCd XRP batteries only need to be charged about 1/2 as much as DeWALT Li-Ion XRP batteries. The only advantage to DeWALT Li-Ion XRP batteries is that they are lighter than DeWALT NiCd XRP batteries. But to me, the disadvantages clearly outweigh the benefits. Basically, the only way that an owner or operator could really utilize the small weight advantage of the Li-Ion XRP battery is to get the smallest, lightest, most compact DeWALT 18 volt drill and use the Li-Ion XRP batteries in this smaller drill. Then you would feel the weight difference. The problem there is that DeWALT does not sell Li-Ion XRP batteries with any of it's compact 18 volt drill kits. So, if you want to do this, you would have to buy your drill and batteries separately, which is a poor value and complicates any warranty issue(s). And besides, so many other tool manufacturers offer tools and Li-Ion batteries that are much lighter, smaller and perform better than anything that DeWALT makes...Makita, Milwaukee, Ryobi, Ridgid, Bosch...all of these companies have Li-Ion tool lines that are much more compact, light, effective, versatile and less expensive than anything that DeWALT makes. So, why did DeWALT make these Li-Ion batteries? Well, I have just one question: If you sold batteries for a living, which would you choose to sell - 1,000,000 NiCd batteries for $89 each? or 1,000,000 Li-Ion batteries for $159 each? The choice is easy. I would predict that DeWALT will have to change their tune soon though, because I won't pay $159 (or even $89) for these Li-Ion batteries. In fact, I won't buy them at all. And I'm sure there are plenty more people right behind me. I'm sticking with NiCd on my DeWALT tools. And if I need something lighter, I'll just have to get it from some other tool maker besides DeWALT.Get more detail about DeWalt DC9180-2-C (2) 18V NANO Lithium-Ion Batteries w/ DC9310 7.2V - 18V Ni-Cd / Ni-MH / NANO Lithium-Ion 1-Hour Battery Charger.
