So far so good. At least it's easy to replace. I don't know what they cost but being Snapon they probably want a premium. I don't leave most of my electronics on the charger. Just periodically plug them in over the weekend every couple weeks. My autel, verus edge, tpms, batt tester, thermal imager, etc seem to like it. Also pull the charge cord on both laptops once in a while to cycle the batteries. Don't know if my method is recommended but it works for me 👌
