Were confident of the quality of our products, and well repair, without charge, any defects due to faulty materials or workmanship within the specified warranty. When the positive terminal is made up of copper, the corrosion will have a bluish color or greenish color, or a mixture of both. At the buzzer, the tester read 5.49Ah and the pack had one LED left. The ideal place to store lithium cells for shipping is about 60% - this is well below the stressed at full charge state of charge, but leaves plenty of capacity for in-transit self discharge or a small battery management system draw. Where some people get confused is when they see a flashing red light. You can buy them in nearly endless quantities at your local hardware store. The model number is LGDAHB41865.

Its worth noting that the thermistor is showing the board temperature, not the cell temperatures. When the battery ambient temperature is high, the chemical reactions inside the battery while charging are enhanced and the battery will charge faster than anticipated. The best charger to use is the float charger which can be left connected for long time as it is is able to which off charge current when the battery is fully charged and will only allow small charge current to restore the battery to full charge status. C3: 12.26V (4.09V) Back in 2016, I tore apart a 3.0Ah pack I had laying around - that particular one had a bad cell group (dead short in a cell - that must have been exciting when it failed), so it was quite unusable and I couldnt really get much data on it.
