Hi Be_Prepared

I just find Lithium batteries just to expensive for general use although they are excellent and very useful in AA and AAA and I will use them in flashlights which must work without fail when the flashlight is being stored for an emergency. They are really useful because of the shelf life i.e greater than 15 years.

I generally use a specific NiMh battery now called Eneloop made by Sanyo. Most NiMh batteries have a serious downside in that they self discharge usually discharging fully after 3-4 months. The Eneloop batteries will only discharge 15% within a year. As for determining the charge on the NiMh batteries the charger,a La Crosse Technology BC900, provides an indication of the voltage across the cell. The voltage normally ranges from 1.20V (empty) to 1.42V (full). The charger also allows the current to be selected for different charging times 200mA 500mA 750ma and 1000mA.
