This extends the useful life of the battery; raw lithium ion is just as (actually, more) prone to destruction via overcharging as other battery technologies. http://batteryuniversity.com/learn/article/charging_lithium_ion_batteriesdiscusses this. Note in particular: "A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety." -- brandon s allbery allber...@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
