"1. 老化既電池, 佢會寫HIGH唔肯叉, 而其他傻充/高速充可以照叉照用"
I think the battery did not pass the C9000's health test (such as, internal resistance is too high). We may try the "break-in" to rescue it. In contrast, ordinary low-end chargers would just keep charging and charging until the battery is totally dead.
"2. 我果部唔知點解, 第3個slot經常未叉完就話DONE "
oops, then it might be a faulty slot 
I've bought the C9000 in 2013, so far so (luckily). And I'm also using nitecore UMS2 for 18650 batteries. I will use the UMS2 to check a battery's internal resistance. |
