Cheap knock-off batteries sometimes have a dummy sen Car Battery Terminal Connector Top Post Positive Negative Heavy Duty Universal U . Batteries, especially in tools that you frequently use, do not last forever. The only real complaints I have are that the BMS is really just a balancing board, and the thermistor is more or less useless. All you do by draining the pack deeply is hurt cycle life. These packs are pretty simple. 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. One of the best know ways is by use of baking soda or cola soda. After the connector has stopped fizzling out, you may wash out the corrosion. Theyll be a bit sluggish on output, but you wont damage them. You can unsubscribe at any time. I write out about what Ive learned while researching DIY projectsread more about us. B+ and B- should be obvious - these are the main charge and discharge terminals. Everything is measured relative to B-, with the relative voltages from the previous reading in parentheses. One of which is very much included in this 100 piece set. Given what it cant do, Im having a hard time figuring out why DeWalt even put it in. These are bought from the local auto parts shop or hardware or supermarket. Battery Connector Power Tools Terminal 10PCS Block Converter For Makita . And, youd be right. It takes some serious amps to spot weld 0.30mm strip. Well, heres another one of the suggestions Im completely ignoring. In either case, the battery should be replaced. The H interconnects are placed a bit more precisely than the interconnects on the older pack I tore apart. Battery corrosion on the positive terminal is indicative of a battery that is being overcharged. Its a hair under 0.012 - so 0.30mm, or twice as thick as the common 0.15mm nickel strip used in ebike battery packs. From left to right, top to bottom: TH, ID, C1, C2, C3, C4.

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). This will lead to the battery being overcharged. The battery anode is always negative This pack is not rare. B+: 20.43V (4.09V). 6. Its up to the tool to determine the cutoff point and refuse to work below that. If you'd like to receive each new post by email, sign up here! The corrosion occurs as a result of sulfuric acid reaction with the metals that make the battery terminals. I literally cant buy the 10 standalone cells for what I can buy this pack for. The rightmost slot is the same thing for the negative terminal. This is a full height terminal (two contacts). All it will show you is a lagging reading of the temperature of the cells near it. The cordless configurator makes it easy: tool bodies, batteries, chargers, lights, lasers, vacuums, etc. I can either stop pulling things apart at this point and rebuild the pack, or I can keep going. When the alternator is defective or running at the wrong pace, it may produce too much electrical current which will end up in the battery thus overcharging it. To give you an idea of how this pack compares to the more common 3.0Ah pack, Ive compared the new pack to the 3Ah ones I have laying around and previously tore down. You can buy a replacement cheaper than I can buy the cells. A defective voltage regulator may send too much current to the battery or too little voltage to the battery. Each bank of 2 cells had a DC internal resistance (on my tester) of 9m, which works out (via math) to a per cell DCIR of 18m. Just be sure to keep the can about ten inches away to prevent damage. Place the two batteries side by side.
