Getting the advertised life out of a battery should not require long, convoluted instructions

An open letter to battery manufacturers and makers of devices that use batteries:

I’m sorry to have to break this to you but nobody reads your instructions and properly calibrates their batteries which is why everyone is so angry at you.

Please consider:

1. Shipping batteries charged and calibrated
2. Putting a “calibrate” button on your charger/device that just does the however many discharge to whatever %/recharge cycles you want, followed by turning on a green light when done

Thanks.
