Questions about this item

How many charge cycles will the 900mAh Li-ion battery last before it needs replacement?

The 3.7V 900mAh lithium-ion pack is rated at 3.33 Whr; typical Li-ion cells of this capacity deliver several hundred full cycles before noticeable capacity loss, so with daily charging you can expect roughly one to two years of regular use.

What is the first limit you hit when running the iPAQ 1900 series all day on this 3.33 Whr pack?

The 900mAh capacity at 3.7V is the limiting factor; under continuous load the handheld will run until the 3.33 Whr reserve is depleted, which occurs well before any thermal or voltage threshold is reached.

Does the BAIPAQ1910 get warm or draw extra power when the iPAQ 1940 is used continuously?

The slim 6.35 mm Li-ion cell operates at normal handheld temperatures; it supplies 3.7V without a cooling fan or additional circuitry, so heat and power draw stay within the device's original design envelope.
