I'm using a wireless Gateway MR-0350T and it's a great mouse, but it sucks the LIFE out of batteries like there's no tomorrow. I swear that this thing goes through batteries faster than my digital camera does. I'm currently using 1.2V Duracell rechargeable 2650mAh AA batteries, but my mouse's power rating is 3V/50mA, so I'm guessing I need to find myself some 3V batteries. But do they even come in AA? I can't find any at the stores around here. I suppose I could cut open a CRV-3 battery, but they're a bit pricey, and once you do that, I don't think they're rechargeable anymore. At least, that's what happened the last time I tried doing it. Am I just going to have to put up with a mouse that dies every WEEK (even though I take the batteries out at night when I'm not using it)?I have a mouse that uses NO batteries, just a PS/2 cord.

It is probably the wireless that is the problem, rather than the mouse itself, but you could save a lot of cash with a more conventional model. Yeah, I know I could do that, but it's so hard trying to imagine myself going back to a PS/2 mouse when I've been having so much fun with this one. Ha. I wish there was some way to hook up a tiny generator to the scroll wheel. Whenever I needed more power, I could just scroll for a few seconds and I'd be set. Ha.That'd be a great idea.
Unfortunately, I don't think there's a way to reduce the power consumption of your mouse.
You can't undervolt it, you see.
Wireless mice tend to use a fair amount of power, but my old one just needed new ones maybe once a month or so, then I'd recharge them and I'd be all set.
When I moved to my laptop I just decided on a USB mouse though, as wireless causes lag in games and it was too expensive at the time.
As for 3V AA batteries, I'm really not sure.
But, I think the 3V rating means it wants 2x1.5V AA batteries - 2 normal batteries.
Rechargables have a lower voltage, but sometimes a higher mAh rating.
So they would probably be right for it.
I think you're stuck with the battery eating beastie.Darn. Well, thanks anyway.

It normally isn't that big of a deal; I have two sets of rechargeable batteries and when I'm using one set, I keep the other set fully charged. It's just that my mom somehow managed to lose my battery charger, and her charger (although a Duracell brand, like my batteries) won't work with my batteries, so I have a very limited supply of power until I can find my charger. Or buy a new one, of course. So, basically, I didn't bother with looking into this issue until it finally became a potential threat. Heh.

Sometime tomorrow, I'll go into town and see if I have better luck finding batteries now that I know I don't need 3V. I mean, there's GOT to be some rechargeable 1.5V batteries out there, right? Eh, I GUESS I'll find out soon enough. I've been needing to pick up a few things from the store anyway.

Other than the whole power issue, I love this mouse. Of course, it is my first wireless mouse and first optical mouse, so I guess I'm bound to love it, eh? I haven't experienced any lag in games...but it might also help that my receiver is only a foot away.Quote

Are there any universal docks by any chance?

I've noticed the same thing. My keyboard is in constant use (I swear my fingers rarely ever leave the keys), but I've never had to replace the batteries and they're just regular ol' alkalines.
