When I got mine I was advised to use the 0.5 setting as batteries "like" a slower cooking so to speak

Hmmm seems like we could be lowering the life of our batteries if we charge at 0.5A, especially if we have Panasonics, or other high rated batteries.

"Lower charge rate (at least 0.5A vs 1A for a 3100mAh cell) won't lessen the wear, in fact it might increase wear due to 0.5A charge terminating at lower CV cut-off current than 1A charge."

Good Point Alvoram, I see what you are saying. Its possible using the higher charge rate the charger shuts off at a lower achieved charge level in the battery. This helps to prolong its life, but means you do have less charge available to use. It will also depend on the characteristics and and charge algorithm the charger uses.

Along with your link this page is also worth reading.
batteryuniversity.com/learn/article/charging_lithium_ion_batteries ....have not read it for a while but think it is the page I want to post on charging.

Yes, I've seen some people say their batteries terminate at 4.2 or just under, mine shuts off at 4.1 on the dot when set to 1A. It makes little difference to the actual amount of time you get from using them, as you most likely know, but apparently helps the life. I honestly don't know for sure, but I have heard from several places, that not quite fully charging the batteries, greatly increases their life, even says so on the page you posted, which is great btw.
