Battery Life
I get about two weeks on NiMH batteries, more or less, depends on the amount of times I hot sync, usually once a day), cheap RAYOVAC Alkaline's can go for up to a month, or more. I put in a fresh pair before I went on my honeymoon, came back two weeks later, the visor didn't die and had plenty of juice to spare, of course it wasn't used for two weeks, so the power drain was minimal.. I also turned off all the alarms and etc during that time.. Hotsyncs really kill the batteries as well as the backlight (I also refrain from using the backlight as well). I also have AvantGo installed and a zillion web pages so my hotsyncs can take a few minutes (again kills batteries). I also keep my IR beam turned off, and only put it on when needed, I was once told it can also drain extra power. Another suggestion to me was not to keep it in the cradle, apparently it will use power just sitting in it.
I would suggest you buy 2 sets (4 AAA's) NiMH batteries and a charger. I rotate my pair. I also use regular AAA's when I happen across them at work (if I am getting low on power).
NiMH's are a bit more expensive than NiCad's but they will last longer, give more power, and not suffer from memory effects that plague ni-cads. Also NiMH are more enviromentally sound (if that sort of thing concerns you).
You can recharge NiMH's 1000's of times.
There are several excellent battery monitoring programs, I use RunTime and BatteryInfo. Runtime will give you a graphical chart and an average time you are getting on your batteries. BatteryInfo will let you change the battery settings on your Visor, NiMH isn't an option so I use the NiCad setting. Also it will let you adjust the voltage warning levels.
I just got a MiniJam, so it will be interesting to see how it affects battery life.. Springboard modules will also affect battery life. The backup module didn't seem to impact battery life that much.
When you change your batteries, you do have a few minutes, but I wouldn't chance it, I have the new pair ready to go before I even pop the battery cover.
