Not sure that's fair - the battery packs come with a 5 year warranty. If you increase the 'full range' - you're increasing the odds you'll need to claim on that, which needs paying for.

If they was true, they could stipulate that enabling full range would void the warranty. This is obviously a cash grab.

Or offer a shorter warranty to people who enable the feature.

... Does.. It?

No it doesn't.

[stevenhuang]

it does, generally the deeper lithium ion batteries are discharged, the higher the likelihood of dendrites forming on the anode.

basically the more time that is spent not in the fully discharged state, the longer li-ion will last.

(this doesn't mean you want to leave it 100% charged either, that can also damage the pack; if leaving for extended non-use, leaving it at ~50% state of discharge is the generally recommended advice)
