The color of the corrosion on the positive terminal will largely be determined by the type of metal used to make the terminal ending. This means I cant pull the PCB off to observe the underside without starting to dismantle the pack with a soldering iron - which I dont care to do. If your Dewalt drill battery is not holding a charge, you can try charging your battery little by little. For some of the packs Ive rebuilt, theyre rare, and either very difficult or impossible to obtain a replacement for. Nothing good, thats for sure. Similar to when your Dewalt drill battery wont charge, the first thing that you want to rule out is the power source. I refer to this board as a BMS, but I think its probably better to call it a balancing board, or a balancer board. The following are trademarks for one or more DEWALT power tools, accessories, anchors and concrete adhesives: The yellow and black color scheme; the D-shaped air intake grill; the array of pyramids on the handgrip; the kit box configuration; and the array of lozenge-shaped humps on the surface of the tool. Prepare a strong solution of baking soda. Contents of opened battery cells may cause respiratory irritation?

DeWalt battery rebuild. And, youd be right. These C2: 8.17V (4.09V) Source: syonyk.blogspot.com. DOT website. The one towards the long end of. Though I might try and see what happens. For Nokia batteries, one of the pins may be a BSI (Battery Size Indicator) pin, which contains a fixed resistor to ground, enabling the handset to The only real complaints I have are that the BMS is really just a balancing board, and the thermistor is more or less useless. Im reasonably certain that this is also one of those things the manual told me not to do - Ive jammed some conductive spade terminals directly into the pack and am discharging it through my FDY10-H battery tester (which I will review at some point - I love this little gizmo for bulk testing). These are bought from the local auto parts shop or hardware or supermarket. And, if youre storing them for a long period of time, dont let them sit completely full. Sitting in the trunk of a black car in Phoenix in the summer will also kill them early. 1. Youd expect to see a nicely balanced pack like mine, not a voltage horror show like this. Place the two batteries side by side. One positive, one negative. Ensuring that only the right quantity of voltage reaches the battery. I dont know what the high temperature cutoff is, but if you are using this pack for your own projects, be aware that the cells will be a good bit hotter than the thermistor indicates. From this angle, the double height B+ and B- terminals are visible, as is the state-of-charge indicator. Never attempt to open the battery pack for any reason. Definitely doing that. The electrical interface is a bit more interesting - and, really, quite a bit of fun! At the buzzer, the tester read 5.49Ah and the pack had one LED left. Theres nothing much on the front either.

Does it hurt DEWALT batteries to leave them in the charger? A battery will overcharge for a variety of reasons including but not limited to: A voltage regulator is used to regulate the amount of voltage that enters the battery to recharge it. This is a tool pack, though. DeWALT Battery 18V 1,3Ah Li-Ion XR DCB185 / N379201 . This has a pair of 30A rated cells, for a total pack rating of 60A, but the interconnect strips and wires are the same as in the smaller pack, so I cant say Id consider this more than about a 30A pack. The best price Im finding (at the time of posting) is two full packs for $150 - so $7.50/cell - with some nice bonus plastic too. The cycle life on these cells, if cycled repeatedly from 4.2V to 2.5V, is (by modern standards) quite poor - under 200 cycles to 80% (2400mAh) according to charts in the datasheet. The LED board is secured to the battery pack with some sort of goop. Battery Charger Maintainer factory-made to detect and check voltage and is safe to use nonstop. Click here. Interestingly, 120Wh exceeds (by 20%) the 100Wh absolute capacity limit on the mailing method in which this pack arrived at my office. Ive looked at the DeWalt 20V Max packs before. The pack has two significant interfaces: The power interface, and the How charged is it? interface. I'm a homeowner and I like to do things myself. B+ and B- should be obvious - these are the main charge and discharge terminals. The previous pack I pulled apart had a pair of 15A rated cells, for a total pack rating of 30A. The plastic wrapper on that cell is incredibly brittle compared to the other cells. Lithium batteries are easy enough to keep alive, but there are a few things to know if you want them to last as long as possible. Thats a stone dead cell bank, if its accurate. As delivered, the pack has 1 of three charge LEDs lit, 17.5V across the pack, and almost exactly 3.5V per cell charge. Everything is measured relative to B-, with the relative voltages from the previous reading in parentheses. The positive terminal from the cells (lower right) is wired directly to the B+ terminal, which is a double height terminal. Start with one end, pry (carefully - dont short the pack out), and it comes out. DeWalt puts proper OEM cells in, as do all the reputable tool pack makers, so I expect it to get within a reasonable distance of the rated capacity. Just like the previous pack, the cells are spot welded on the ends with some nickel strip (presumably 0.30 mm - its hard to measure without ripping things apart, but thats what the previous pack had, and this feels the same to me). Im going to grumble a bit here. The solder connections are substantial. On top of it, this BMS cant even protect the pack from an overdischarge or any sort of fault condition. Charge the battery packs only in DEWALT chargers. Well, probably. 10.59 . Though the petroleum jelly layer will wear out with time, it is one of the cheapest ways of preventing positive terminal corrosion. Except, I apparently did charge it while damaged. Time to tool up?

For more information consult theU.S. Powers entire DEWALT line of 18V tools allowing users to run multiple tools off of the same battery The DeWalt charger (at least the one I have) doesnt charge past 20.5V for the full pack - this works out to 4.10V per cell instead of 4.20V. Lots of solder, lots of thermal wicking, and lead free solder leads to needing a serious amount of heat. But, if you do, dont be stupid. For the last two cells, probe C1 and B- (the first cell; really the last in logical order), then C4 and B+ (the last cell; really the first). You use a hobby-type balance charger to charge any DeWalt 20V Max battery pack, and you dont even have to open the case. Im not surprised, but as one who deals with the proper dangerous goods/hazmat shipping for battery packs on a regular basis, I really dont like to see batteries shipped around in violation of shipping laws. With the Security Screws out, the top comes off cleanly, exposing the pack guts and a really neat little spring for the pack release button. Stop using a battery as soon as you feel a substantial decrease in power from the tool. While its fun and sometimes more cost effective to Do It Yourself. Sane enough, though one LED means you really should be charging it now. The low capacity (1500mAh - below half of what a high energy cell can do) is the price you pay for a cell with that kind of power output. This is on the back of your drills computer chip.

Overcharging may also occur when the charger is improperly used like selecting the wrong voltage, using the wrong charger, or staying the trickle charger connected for too long even after the battery is fully charged. This unit took more heat than is usual to desolder stuff. All it will show you is a lagging reading of the temperature of the cells near it. These are almost certainly the voltage sense/balance wires. Looking down into the gap between the prongs and the board, theres what appears to be a small IC in there, and a few more passive components. Next, I want to get the BMS off - that lets me get deeper into the pack, and figure out whats going on with the BMS board (not that its much of a management board). 11.63 .

I have nothing but good things to say about this battery. On the left, the state of charge board has three LEDs and some basic voltage sensing logic on it to light the proper number of LEDs. Of course, being a well equipped techno-weenie in a solar powered office, I have an entire kit of security bits, because I dont believe in keeping me out of things. If one of them is significantly less (like my 0.02V jump), youve got a dead cell bank. C2: 4.10V (0.02V) (uh oh) After removing the conformal coating, I measured10.68k at 21.6C - so probably a standard 10k/25C thermistor. That makes sense, though. Type 2, whatever that means. Comparing them side by side, you can see this - the older 18650 based pack and this 20700 based pack are pretty much identical except for size (and the fact that I dismantled the older pack a good bit further). The good news is that a faulty voltage regulator can be easily replaced at an affordable cost. Just shove some terminals in and dont be stupid about your low voltage cutoff (15V is a good idea). And the rest isnt very pretty either. Dont leave it running and drain the pack, but this would be a really easy pack to repurpose should you care to do so.
