Actually that's not quite what I said, nor do I think possible savings are "a negligible amount" by any means. Avoiding the last .1 Volt of charging (stopping when the top LED is lit but before the charge light stops flashing for instance)
doubles the lifespan.
600 recharge cycles not
300. Double the lifespan at the expense of 10% of the charge capacity. You decide if that's significant or not. More over, the next .1 costing an additional 20% of capacity (also 'hidden' after the last LED lights) doubles it again to
well over 1000 cycles. Makers are happy if you get enough battery life to get out of warranty, then are looking to sell you a replacement (and it's way more than $20......). They also make money on more sessions per charge. Where do you think their advice might be pointed?
So, give up a session or less and double the lifetime. Give up a bit more (stop at 4.0 not 4.2) and you get a battery you can recharge every other day for over six years?
My advice is to never do anything but recharge after a session that showed no LEDs on start up (OK to do that session, but no more before recharging) and take it off charge before the charge LED goes solid when you can and and it should last a very long time. Run it unitl it locks out a few times, or habitually 'charge until it stops' and don't expect long battery life. Charging 'to the top' only takes a cycle or two off the total each time you do it, but hammering the discharge end can be a serious life taker.
Your call, but you might want to check out the text around Table 4. FYI the top LED lights just after 4.0 Volts is passed on charging:
