Batteries and laptops

A couple more words about my 2006 Macbook Pro: my current battery is at 105 battery load cycles. It is the second official battery I've had for this laptop. Now granted, I do not use it so often... but still, after only 105 load cycles, the battery is in 'Service battery' condition, and is down to a capacity of 2218 mAh, where it should really be at 5600 mAh.

Sigh. I should really be able to crack open the battery case and reuse any good cells from my original battery to replace any dead cells in my current (newer) battery. Batteries are actually really complicated, but I find that the industry is not doing very well with battery management... we should be planning for longterm usage (like 10+ years) and provide for capacity management on a longer term basis. At this point, battery management seems concerned only with cycle count and maximum capacity tracking, rather than proper recharge cycle execution.

Anyway, I assume that electric cars are managing this a lot better these days. Something to look into...
