Are the charger balancer boxes all the same or are there different ones for different Batteries I have DH9100 changed the board I'm guessing bad Batt

As long as its a 2s 7.4v, the stock charger should work fine. My second DH came w/ a defective battery (1 good cell, 1 bad cell). Cheap Chinese batteries... Any more questions, let me know.

Looks like new batts. From the fourth or fifth picture the battery port is level with the heli. Old styles had the battery port hanging down a bit at 10 degree angle, which was a worse design.

Honestly I have no idea, I would bet that some of the pins are for some sort of data connection though, since my impact will go from full power to dead instantly. There is no weakening of the tool as the battery dies, it will just stop working. With the 4 ah batteries I get over a day of hard work out of one battery. I'm curious as to why you are asking? The charger is pretty cheap when compared with the tools and the price of the batteries.

Cecelia: PLEASE SEE MESSAGE BELOW FIRST!PS: According to the page at the URL I left in the first post, (The product info page,) this battery FITS YOUR DRILL yes. I copied the "972's" to here: "DW972, DW972B, DW972K, DW972K-2, DW972KQ-2, DW972KS-2, DW972RLK2" If nothing is down in the hole in the charger the batteries fit into, then I suspect you DON'T have the original charger! Somehow? OR... possibly the contacts are bent? (small metal "posts" on the battery that make electrical contact) The drill has 4 "tabs" that are pretty "forgiving" if a contact on the battery is bent... the charger, not so much!Hope something here helps!Joe Cecelia: PLEASE SEE MESSAGE BELOW FIRST!PS: According to the page at the URL I left in the first post, (The product info page,) this battery FITS YOUR DRILL yes.

yes I think they are the same, the difference they are designed for different mah (mili amp hours), this determines their output and service between charges. the larger the mah, the stronger the battery

The numbers are scratched off charger. These batts are the same as the rest of the 18v. They work and hold charge great. I will be getting more.

yes - no difference is apparent. Ive charged the new battery with the new and old charger.

I gave the one I bought as a gift to a friend, who has drill and impact, he has had no problems charging his.. If you still have your old battery compare them to make sure they match up. Or see if friend has a charger to try. Otherwise I would see about returning it, it may be defective.

The lithium battery housings are made different than other battery housing so they will not interchange

These are HHR 75AAAB. I assume they are the same voltage, but hold a different amount of energy. If you use them, make sure all the batteries in a stack are the same kind.

I just Google searched my battery and found one identical. I also ordered a wall charger because my phone charger kept failing. Now I have 2 batteries that I keep charged with the wall charger.

The answer from NLee is the best one - excellent information. I have a number of different chargers, and the only one I really trust is my La Crosse BC-1000. I have compared the results from the other, cheaper, chargers with the same batteries, and the results in final charge voltage and available current is often quite different. You probably do not NEED to buy a new charger for these batteries, but if you want them to really last and your current charger requires you to charge them in pairs (a telltale sign of cheap chargers), I highly recommend you invest in a new quality charger.

Both batteries and chargers are sold on Amazon. Search for "18650B Protected" for the batteries, and "18650B Charger" for the charger.

My Charger is a DC9700 92.6 battery charger, it also says charge only 7000, 9000, or 9100 batteries only. I don't have a 9100 charger, but what I have will charge 9100. I hope this will help, I have recharged these batteries several times and had no problems yet. I got these batteries about 6 - 8 months ago and still no problems. I hope this helps.

I don't know that mush about the different batteries. My old charger bit the dust so I purchased this one for my 18 volt hammer drill and Sawall. It works fine.

I think all the batt. have numbers on them, if it is the same it will work. Or you could just call the fractory #.

Carefully check that your Duracell charger is not for NiCd batteries. It must say that it will charge Ni-MH batteries instead. They are not interchangeable.
