Depending of course on how long it's used for each day, but if I use it solidly 
for successive days, the battery life would be no longer than a few days - a 
week maybe? I was aware of the possibility of frequent battery replacement 
before buying, and so ran with one of the WAMUG subscribers suggestions to use 
rechargeable batteries.

There does seem to have been some improvement in battery life over time, but 
I'm saying that without having kept any stats. It's just that when I first 
bought it the batteries seemed to last only a couple of days, whereas a now 
much longer. The batteries were new also, so it's probably got more to do with 
the batteries needing a couple of recharge cycles to reach optimum power.

I've just checked my battery level indicator again and it's calling me a liar. 
Now 57%. Yet it was definitely at 61% for a period long enough to assume it was 
stuck on that figure. Maybe the batteries had an extra bit of oomph at the 61% 
level?? But I'm talking about it being there for a few days, and also they went 
flat shortly after I checked the power level, which had indicated 61%. Unless 
there's something which needs to be done to refresh the battery level 
indicator, which maybe I didn't do, like turn the mouse on and off or something?

Just before last battery changeover, the cursor started tracking really slowly 
and unresponsively. Initially I thought it can't be the batteries because I 
would have received a 'low battery' warning flash up on my screen. I think that 
was when I checked the level only to see 61%, a level I recalled it being at 
the last couple of times I'd checked. But the jittery cursor persisted, so I 
swapped the batteries anyway to see if that changed anything. It did. Problem 
solved. Some time after that change, I checked the battery level indicator 
again - 61%. In hindsight, the post changeover check could have been pure 
coincidence that right at that time the battery life had reduced to 61%.

Regards the jittery cursor, it could be that I wasn't looking at the screen at 
the time a low battery level warning flashed up, but then on previous 
occasions, once the battery goes flat, the cursor just stops moving (and I 
think a disconnection messages flashes up?), there has been no period of poor 
performance.

For the time being, no problem. I would be peeved without rechargeables though.

Cheers, Steven
