Attach one end of the negative (black) jumper cable to the negative terminal. This is the negative end, and it doesnt look like its burned through (I scraped the corrosion off and it looked normal), so still no idea what happened. C1, C2, C3, and C4 are direct access to the voltage of each cell group - so, as shipped, 3.5V per cell. But theres not much under there. I played with it a bit, and it certainly seems to be a balancer, but I dont understand why it exists. The third pin is usually for an internal temperature sensor, to ensure safety during charging. Cheap knock-off batteries sometimes have a dummy sen This new pack is supposed to be twice the capacity at 6.0Ah - or, as the front cover helpfully explains, 50% More Capacity vs DCB204 4.0Ah Battery.

Corrosion At The Battery Negative Terminal, NOCO GENIUS10, 10A Smart Car Battery Charger. The leftmost slot is a double connector for the positive terminal. The DEWALT chargers have a maintenance mode which allows batteries to remain in thecharger, maintaining a fully charged pack until the user is ready to work. We take extensive measures to ensure all our products are made to the very highest standards and meet all relevant industry regulations. One thing of note here: The battery is always connected to the terminals. The increased resistance will make the battery heat up and this will cause water in the electrolyte to evaporate leaving the battery without acid. This is probably fine, since its unlikely that most people will use the pack for other purposes. A bit of fiddling, and the BMS is clear! 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. I refer to this board as a BMS, but I think its probably better to call it a balancing board, or a balancer board. Battery corrosion on the positive terminal is indicative of a battery that is being overcharged. Do not probe pack with conductive objects. Like the probes of a voltmeter? Except where otherwise noted, content on this site is licensed under a a Creative Commons Attribution 4.0 International License.

Its been a little while since Ive had a shiny new tool battery to tear down! Measurement of the cells indicates that they are, indeed, 20mm in diameter (you cant see the entire diameter on the ends as the ends are a bit curved). C4: 12.19V (4.00V). The wire routing for the balance wires is really well done. They do the same, but with negative reports. 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. The rightmost slot is the same thing for the negative terminal. Theres no glue or anything else involved - the pieces just slide free. Start with one end, pry (carefully - dont short the pack out), and it comes out. This means the power delivered is less than the output the battery is capable of giving. The spot welding points are marked by small divots in the strip, and the slits are pretty standard on thicker nickel interconnects. Does it hurt DEWALT batteries to leave them in the charger? What likely happened is that one of the cells shorted internally, and the other one dumped its current through as well. You will need to jumpstart the fuse. Well, not quite, but that math works with their admittedly creative naming for this series of packs (personally, Id call it an 18.5V pack, but thats not a substantial improvement over the old 18V NiCd or NiMH packs - you can buy straight through adapters). The New . Weve all been there, our battery indicated that it was fully charged. Transporting batteries can possibly cause fires if the battery terminals inadvertently come in contact with conductive materials such as keys, coins, hand tools and the like. Except, I apparently did charge it while damaged. TipsThe red wire is connected to the positive terminal, black wire is connected to the negative terminal. The exposed balance wires (coming from the center of each H interconnect) go into the board and are routed to the C1-C4 terminals in the center (since these dont handle nearly as much current, they dont have to be double height). The best way to find the DEWALT cordless tool for your toughest jobs. You should stop using a battery as soon as you feel a substantial decrease in power from the tool. This is a full height terminal (two contacts). Power tools draw higher currents and have sporadic drain rates minimizing the opportunity for the battery to develop a memory. The board has the ID resistor and thermistor as well, but it is by no means a battery management system - it doesnt appear to do any balancing, and is quite simple. If youve managed to get cylindrical lithium battery contents onto your skin, or liquid into your eye, youre having a really, really bad day. Each cell negative terminal is connected to the next cell positive terminal and at both ends, a terminal post is connected to the respective poles. That leads to more shipping laws, which just annoys me even more. With batteries, one can generally get a lot of energy (watt-hours) or power (watts), but not both. Terminals. I have the DeWalt 18V XR2 battery - also a heavy pack at 966g (2lb 2.1oz). Power tools are considered high-drain applications. Anyway, just my thoughts. The top left cell also looks a bit off (the discoloration on the positive terminal doesnt exist on any other cells). 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). I gave up after a minute or so of trying to free them with my big iron, and went to Plan B: Pliers and wire cutters.
