Today I went to use my Pronto the battery light was on, with the batteries in only about a month. I was thinking I should invest in the charger, but I checked the batteries they were fine so I put them back in and the Pronto said they were 100%. Anybody else have this problem??

Chances are, you use it for a half hour or so and the batteries will be right back down at low. It takes it a little while to get a true voltage reading.

I also have removed "old" batteries and re-inserted them to see what would happen. Pronto stated them as being 100%; before I removed them it said they were only 20%. However, they did wear down very quickly after re-insertion. This leads me to believe that Pronto believes that anytime it's power source is removed and replaced it thinks that they must be new batteries.

Sounds more like alkaline batteries that are recovering after being loaded. Alkalines will do this and show a higher terminal voltage initially when the load is applied but they will drop back off once the load stays for a bit. Has to do with the internal impedance characteristics of alkaline batteries. If you were to short circuit an alkaline battery for a period of time, then remove the short, the terminal voltage will climb back up to a near "fresh" value until it is again loaded, at which point, terminal voltage will drop to reality indicating the true remaining capacity of the battery.

To clarify a few things....
-The night before it said 75% good
-the next day after I reinstalled them its still 75% good
-the batteries tested 1.3v-1.4v on my multi-meter
(still good)

Has anyone tried using AA lithium batteries in a Pronto? I'm curious to see if the battery life would be greatly improved.

As soon as this set of batteries is done I am going to get a set of NiMH batteries for it... they are $40 for 4, and a charger...

Brooks, why not just pony up the extra few dollars and get the re-charger. Comes with it's own NiMH pack and a cool stand to put the Pronto on when not in use . . . depending on how long my first set of batteries last, I may pick one up myself . . .
