VX revolution with Rechargeable battery

is it OK to use rechargable battery (NiMH) for the VX revoltion?

the NiMH has 1.2v instead of the 1.5v of the normal battery.

logitech saying rechargeable battery life will be reduce.

what is your experience with this mouse?

i use sony 2700 mAh NiMH battery with my mouse.

 

Just try it and see how long the rechargeable batteries can last and if they get damaged by the mouse.
Just use a few rechargeable batteries and when the mouse reports they are empty messure their voltage.
It's possible that the mouse discharges the rechargeable batteries below 0.9V which can damage NiMH batteries, that means they can't hold their original capacity any longer.

 

Thanks for posting this interesting thread wobble987. I have this mouse and am using a rechargeable battery in it with a voltage of 1.2v. I was using an alkaline battery all this time and decided to just use a rechargeable battery recently(~3 weeks). I didn't even know this was an issue till you posted the links to Logitechs site. I will say I am getting a lot lower battery life with the rechargeable than the alkaline. This really sucks. I don't even mind the the lower battery life but what bothers me is the damage to the battery! Rechargeable abtteries are expensive. Might have to go back to alkaline.

 

frank, i somewhat doubt that the mouse runs below 0.9v let alone 1v dont the NiMH battery design to be run down? got any info on the NiMH battery technology? care to share?

thank you fire snake,

im not sure if it will ruin the battery.

i've researched the data on the energizer and duracell site, they have this "datasheet". it shows the curve voltage and such. if you want to see, google the document name, result should be right on top.

document name: "nh15-2500.pdf" (energizer)
it seems that the NiMH starts off with 1.4v then it drops drastically to about 1.35, then slowly to about 1.28v, where it will stay there most of the time, till it hit 1.2v, then it will curve to 1.1v where soon it will hit a snag then very quickly goes to its 0.9v cut out.

document name: "e91.pdf" (energizer)
the standard alkaline battery on the other hand starts out at 1.5v where it will sharply drop to 1.4 upon usage. the battery will slowly drop it voltage till it hit around 1.1v, where it will hit a snag (similar to the NiMH) then it will curved sharply to the 0.8v cut.

document name: "MN1500_US_CT.pdf" (duracell)
duracell alkaline, similar to the energizer. start at 1.5v but it will drop to 1.3v somewhat sharply, then will drop gradually to 1.1v, but this one will still drop quickly still although not as fast as energizer to 1v, then it will curved sharply to 0.9v, then it will drop to 0.8v very soon after.

not sure if the difference between these type of battery is from the scaling of the graph, but this is what i can conclude from glancing at the graph.

in conclusion, i think this will not probably damage the battery or the mouse, i think the mouse's battery indicator will just report the battery charge level as being in the medium level most of the time, save for the first few hours/days, that you use the mouse after the battery being charged. which is what i've experienced now.

what do you guys think of my conclusion?
