I think the *frequency* should increase with charging current, by somewhat
1/250 sec*mA^-1, meaning with 100mA charge you get 1 cycle every 2.5s, with
1A every 0.25s aka 4blinks/s.
Duty cycle (on/off) should increase with battery charge to 100% on while still
on charger but battery completely charged.
Feel free to add this to the wiki.
