Draining the battery below 15-20% is generally a good idea before replacing or maintaining them. I usually just use the computer at full brightness until i get the low battery warning, then shut down.[br] The draining is so there’s not too much energy left that can escape if the battery would be damaged or punctured. A fully charged battery can unleash !&&* to you and your surroundings.[br] Happy fixing!
