li ion batteries
technology is sure a hassle at times.
yet how i often marvel, and fawn over em' ?
today i finally unpackage my laptop battery, which was late in service by at least a few months.
been using my laptop without the pack.
but anyway, if you're into technology, or even if you're not that into, you may have perhaps heard of some rumours regarding battery lifespan and charging and stuff.
say, the frequent rumour that batteries should be left to discharge completely before being recharged. if not there'd be some memory effect that kicks in which remembers the battery for only charging up to the certain state.
it is noteworthy that li ion batteries are different from the old sch nickel/cobalt variants, with memory effects.
li ion batteries do not have memory effects, and thus it is ok to charge them (and advisable to) at any point, instead of letting it run down all the way to 0%, which will kill its lifespan.
i dont quite intend to go into a guide here and explain all the chemistry and explaining battery charge cycles, but it seems like good battery care would involve several points.
keeping it away from heat.
not letting it do the deep discharge-charge method, but frequent small charges to top it back up.
not leaving it inside the dock permanently while connected to the A/C supply.
and then there are tips like recalibrating once every 30 charge cycles, which will involve a deep discharge.
or, conditioning new battery packs that may have instructions such as doing a calibration for three times before standard usage.
say, what else was there to it?
im pretty sure most people by now would be quite terrified, because they wouldnt go to such extents to protect and care for their batteries. or perhaps the lack of awareness fails to get to them.
batteries, they do seem more cumbersome than anything in the world now, that includes the North-South Korean conflict, managing troublesome girls, and well, almost about anything.
may i take the lazy way out? maybe not this time >.<
Time to give my new battery some good treatment.
