In my experience, what causes them to swell is leaving them at a state that's higher than the safe storage level for a long period of time. The auto-discharge feature should solve this problem most of the time, but for example if one is using a lengthy time before the auto discharge begins (e.g. 10 days) and then also tests the charge by pressing the button often, the auto discharge resets itself to whatever you had it set to (e.g. 10 days) and the battery will never get a chance to auto discharge. Hence, you end up with a swollen battery. |
