Consumer gadgets too. I tend to replace the Li-ion batteries in my phones and laptops every 2 or 3 years and it's a pain. I'd pay extra for something that lasted a decade.
Consumer electronics use Lithium Polymer generally, which has one of the lower useful lifespans.
Just replacing it with LiFePo batteries would give you 4x the lifetime. Of course, with current technology the battery would have to be twice the size.
