Lithium Batteries



I've begun using litium AAA batteries in my 48GX and HP 71B with excellent results. Does anyone else have experience with this? I ESTIMATE 3X the battery life versus alkaline batteries. Is this correct?

The lower the consumption of the calculator, the bigger the benefit - they don't suffer from self-discharge (they can be stored for years). For high-power devices, the benefit is smaller (cost per hour of usage), as the Alkaline batteries are much cheaper - the Lithium cells do have a higher capacity though and will last longer.
