![]() ![]() ![]() I found that out by charging again until the green light appears, which increased the third number by one and left all others unchanged. The third number means "charge cycle count". I can confirm this for M28 batteries as well, as I just tested it on a brand new one: neither fuel gauge LEDs nor flash codes worked before the first user charge. I can confirm that with a brand new M28 Redlithium battery that I just charged for the first time and that is now reporting 0000 for this number right after the end of charging.Īlso, it is reported in the Milwaukee V28 battery troubleshooting guide that fuel gauge LEDs do not work at all before the first charge, so it seems reasonable to assume the flash codes will not work until then either. More precisely, it is the day of first user charge, not counting the 50% factory pre-charge that the batteries come with, as figured out in another answer here. So 1638 days back from the date of your question would mean S( says WolframAlpha).ĭay zero will be the day of first charge, not of manufacture, because the date of manufacture is already included on the battery as a Milwaukee date code (though for this one I can't detect one, bit strange). This number seems to increase by one every day (I observed that over a few days also somebody else claims for M18 batteries it changes daily, see below). The second number means "days since first user charge". It was always 0001 for my working batteries, and is 1000 for a broken Milwaukee M28 battery that refuses to charge because of an accidental deep discharge by leaving it uncharged for too long. The first number probably is a battery status code. Applying this, the numbers encoded in your example would be: The "all together" flashes are probably just separators. So it appears to me (from similarities with flash codes from cars in the 1990's) that the number of flashes will indicate digits. Since there is no official documentation, we need to do a bit of reverse engineering. working fine but in use for some years already.model: Milwaukee M28 Lithium-Ion 3.0 Ah (so, not yet the new M28 REDLITHIUM series).I found nothing about them in the Milwaukee V28 battery troubleshooting guide, and there is seemingly no equivalent document for the (newer but very similar) M28 battery series. What do these battery flash codes / blink codes indicate? Here, "all" indicates one flash of all four LEDs at the same time, and a number indicates one flash of that LED (counted from left). I just tried it twice in a row, and each time the readout was as follows: all 4Īll all 1 2 2 2 2 2 2 3 3 3 4 4 4 4 4 4 4 4Īll all all all 2 2 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 When I press the fuel gauge button on my Milwaukee M28 battery pack for a bit longer (some seconds), the four fuel gauge LEDs start to blink out what seems to be diagnostic codes. ![]()
