How's the battery life? Anyone using rechargeable batteries with it, if so how much time do you usually get off a set of fully charged batteries?

I'm still on the original batteries. Used a fair amount. Don't think rechargeable are necessary

I don't use rechargeable batteries and certainly don't find it necessary. I'm still using the original batteries I inserted when I purchased the Leica and months later the unit still works like a charm. I'm shocked at the outstanding battery life and how well this unit works. Extremely accurate and saves me tons if time measuring.

Not using rechargable batteries and the ones I am using are still fine, over two years later. But it doesn't get used a lot.

I haven't done a test (like running movies for hours to clock the battery life), but I would say about 6-7 hours of use. I use it a lot, but only need to charge the battery every 2 days or so. No battery gets used when it's off, either (I know that sounds silly) - for example, I had charged it fully and the. Had it in my bag for 3 days before taking it out to use it, an the battery was still charged to 100%. So far, great battery life. Hope that helps.

I charged it for 12 hrs and it was fully charged. after that initial charge it depends on how long I use it. I do not charge it after every use because I have always read that is not good for rechargeables. and I do not leave it plugged in either.

I recharge about 1-2 weeks. I wait until the battery drains completely and it basically shuts down on me. Then I recharge fully. It's a lot longer than every few days.

Battery life has not been a problem. EVery once in a while we need to remove a battery, let it rest for a few minutes and then replace it. Otherwise, no problem.

I haven't timed the battery life but I use rechargeable batteries and have gone through multiple 2-hour practices on one charge.

We are lucky if the rechargeable batteries last 3 hours...so very annoying. I started doing a little research and found that these rechargeable batteries are the best on the market : eneloop AA 1800 cycle, Ni-MH Pre-Charged Rechargeable Batteries, 4 Pack (discontinued by manufacturer) Anyone have any experience with them?! They have really good reviews. I'm wondering if I do get them if I should get a better battery charger, if it really matters at all?!

I have one of these...use it daily & can expect about 6 months to a year from it before I have to charge the batteries.I use rechargeable batteries in mine.I believe the length of time it will last, depends on how often it is used, & what the quality of the batteries are.Example: Duracell bateries will outlast store brand name batteries by a long shot....

Battery life is good; the person who told me about. It, used it non stop for several days and since then infrequently but has not had to change batteries. I gave one to someone the day before yesterday and they used it 2 nights in a row non stop!

At least three months of heavy use. No warning of the batteries dying yet either. You don't have to turn it off and on. It will turn itself off after roughly 10-15 minutes of being still and takes about a second to turn back on by moving it around. It's quite good, and probably even better with rechargeable batteries.

I agree for me last around 40-50 originally. Over time I'm guessing due to battery wear its portability duration is greatly reduced. I've had mine a couple years with moderate to heavy use. Doesn't seem to last over 24 hrs now without a recharge.

I use rechargeable AA batteries. The initial investment might seem pricey, but it takes years of use for them to wear out, making them a great deal in the long run. Seriously, about $12 for 2, 3, or 4 years of service? So much better than using throwaways!

I prefer this AAA battery set, they last months before having to be replaced. The newer built-in rechargeable battery set i believe they advertise as having a 24hr battery life before having to be recharged. That made my selling point the AAA pair.

battery life is good (Haven't done an exact measurement, but it seems like I recharge about every 3 or 4 days). It has an automatic sleep function that preserves the battery life. Full charge in about 2 hours.

Battery life is very solid. I work 8-12 hr days with it and I would estimate batteries require replacing roughly every month to month and a half. I would note that I tend to leave it on all the time and it goes to sleep when not in use. You only need to click to wake it back up again. Am pleased with battery life (I find re-chargeable batteries are a good investment).

I used mine for several months with light use. It doesn't seem to turn off automatically for me, but now that I think about it I can't remember if it's supposed to. In general I have no complaints about the battery life, or anything really. I like mine a lot and would consider it one of my best buys.

I find the battery life to be really long, although my use of the keyboard is sporadic. I've been really pleased at how infrequently I have to recharge. Sorry I can't give you a more precise answer. One thing I try to remember to do is to power off when I'm not using the keyboard. Good luck!
