I would add something.
Don't use a third-party charger IF it make the battery hotter than with original charger.
"Hotter" means significally hotter, 10-15C or more, what can be detectable with fingers.
First, excessive heating is just dangerous, for any type of batteries.
Second, lithium battery when charged at hot temperature, can get lesser charge (in contrary to estimations), and it's lifetime also shortened. No, cold also doesn't help to charge.
Normal behavior of battery under charging in correct charger at room temperature - to be a slightly warm, no more.
