Powilling 18V Li-ion Battery Comaptible with Dewalt 18V Battery XRP 6.5Ah

I have bought one of these batteries after 4Ah Ni-MH replacement from Vanon proved to be too good to be true. You can find a separate negative review on this fake battery on Amazon. This Li-Ion battery however is very different. It is constructed out of 10 cells (18650 size, 3.6 V) and has a circuit board on top of cells to provide safety and charging capabilities in a regular Dewalt Ni-Cd charger. The fit of the battery to the tool and charger is excellent. Battery weighs 647 g, the original Dewalt Ni-Cd one weighs 1072 g. Battery came half-charged, but provided very good power even in that condition. Charging in the original Dewalt Ni-Cd charger DW9116 did not present any problems. The test discharge cycle at around 1A current load lasted 4 hours - until battery voltage dropped to 15V (or 3V per cell). This translates to 4Ah capacity, not 5Ah as advertized. I did only one discharge test, so I cannot say my result is 100% correct, bit it is much better than original Dewalt XRP battery at 2.4Ah and light years ahead of available Ni-MH replacements. This battery charge will last a long time. Charging a fully discharged battery took about 2 hours. The charger stopped the cycle while battery was on its 4th light blinking. The battery was not fully charged and measured 19.88 V. Pushing the battery test button lights up all 4 lights, but fully charged battery is at 20.3 V. Removing battery from charger and putting it back will put additional charge in the battery until battery circuit will cut it off. If you want your Li-ion battery to last, do not keep it fully charged or discharged for a long time. It would be most happy stored at about 50% charge. Charge it just before you need to use it. So far the battery looks and performs very well, but time will tell the full story. P.S. It is October 2021 now and I have used the battery quite a few times. The performance is still very good and I like the fact that battery does not loose its charge in between uses. It looks like I made a good choice buying this battery and keeping my old 18V drill.

Great for changing my dewalt 18v nicad over to lithium and use the same old battery charger. Plenty of power and holds charge very well

This is a pretty good battery, the only reason I gave it a 4 instead of a 5 is that charging it can be a bit of a struggle. I have to on occasion reset the charger so it finishes charging. Today I had to reset it 4 times, each time it hit the next level on the charge indicator (on the battery) it said it was done charging. This battery LASTS. Hold a charge well too! Thinking of getting another soon.

Exactly what I needed for a replacement.

I charged this battery overnight in the recommended DW9116 charger - that seemed to work OK (though the battery has to be forced down a bit to seat in the charger). Installed the battery in my Dewalt reciprocating saw, and it worked great for 5 minutes of intermittent use, and then failed completely. The LED display on the battery still shows a full charge, but the saw won't run (it does run fine with an old battery, so the saw is not the problem). When the battery is inserted in the charger, the red charger light does not come on, so it does not even sense the battery. So instead of working on my project, I am wasting my time packing this product up for a return. Can't recommend it, though due to many good reviews I am (foolishly?) opting for a replacement rather than a refund. UPDATE: Yes, it turned out to be foolish to accept a replacement instead of a refund. It took a bit longer for the replacement to fail, but only because I did not use it much at first. I might have gotten 10 minutes use from the replacement. Failure mode is similar to the first one. We are all trying to find a viable alternative to the overpriced OEM batteries, but if you value your time and sanity I suggest you avoid this product.

Fits good. Works good. Keeps the old tools going.

I've had good luck so far. Battery charges using std Dewalt NiMH charger, although it does need a couple tries (plugging and unplugging in charger) to fully charge without charger rapid flashing light. Not surprised as the charger was not designed for the newer battery technology, but it does work. The green LED's on the battery should be used to determine charge status. The battery itself is powerful and definitely outlasts an old worn NiMH type.

Haven't had the battery that long to assess long term battery life, but lasted a lot longer than other batteries under recent heavy use. The battery power level indicator is an excellent feature of this battery. Battery power indicator showed it got down to only the 2nd level of four after using it in a reciprocating saw cutting numerous tree branches. I did notice when recharging the battery using a standard Dewalt 18v charger that it seemed to "stall out" at level 2 with the battery indicator blinking and the charger indicator light showing solid red, indicating a full charge. I just removed the battery and replaced it back in the charger and the battery shortly indicated a level 3 charge and completed charging to a full level 4 charge. The battery releases easily from the tool, unlike some 3rd party batteries that required disassembling the tool to remove the battery. As an aside, I previously had Dewalt18v NiCad batteries rebuilt locally from two different chain stores that ended up cutting internal thermal sensor wire and stripping out and cracking the battery screw thread bosses so the battery case would not stay together. Could not recommend to anyone to have their batteries rebuilt. I have also ordered new 3rd party 18v NiCad replacement batteries that did not perform half as well as this 18v Lithium battery. I have two of these batteries and will probably be ordering a third. So far this is the best solution I have found for having an 18v Lithium battery or any battery for that matter to use with my 18v NiCad based Dewalt tools.

Excelente producto

Esta muy bien la pila solo que no es compatible con mi taladro y cargador gracias

Hay que ver como se comporta con el tiempo
