What is the battery life? The brand I have the batteries last about 1 month.

I've had two installed for about a year and they still are working fine. I test them periodically but they aren't showing any signs of wearing out...

This detector uses a 9V battery. I installed 3 devices in Sept. 2012. At 22 months, batteries still have > 8.5V. I do not know the ultimate battery life for the average situation; however, changing batteries on a schedule (say yearly at a cost of about $1/per battery) or when you detect a battery discharge problem could be a good policy.

Less than 4 hours for mine. The battery really does last a long time. I've had mine for several months and use them for up to 4 hours or more at a time, a couple of days a week. I have only had to charge them a couple of times so far. I am impressed with the battery in these.

I have had the battery less than a month. It is great so far. I would recommend that you find someone who has had the battery over a year. That is when my previous third-party battery from another company failed despite not being recharged much.

Battery life has been great so far. I've recently switched over NiMh rechargeables for all of my batteries. Haven't had to recharge them for about a month. The mouse has an auto shutoff feature after periods of inactivity.

I'm using Panasonic eneloop 2000mah rechargeable, which is low discharge battery and they are still going strong after month. Will update when they need recharging. I used the Maha MH-C9000 to cycle and charge them as well.

My batteries last about a month. I got a value-type pack from monoprice, so they're not the greatest, but they still last a while. Not sure why so many people are having issues, maybe the battery compartment gets wet from splashes or condensation for them?

I buy these batteries for my husband who wears Oticon behind the ear hearing aids and they last for about 4 days, which is about the same as when we were buying the name brand. These are the only ones I buy now. But remember that it depends on the device you are using. Some drain batteries faster. For the price it is worth comparing them to the name brands.

I bought these same batteries in May 2012. I recently ordered these again. (different supplier) I did not have any complaints or would not buy them again. Any brand battery can have a bad cell in the pack. I also like Renata brand. (not sure I spelled that correctly) Another choice would be Energizer. These 3 brands seem reliable over the years.

The battery it came with lasted about three weeks. I suggest buying name brand batteries. They last longer.

sorry I can't tell you the brand, but however I'm a Inspector and I keep some other rechargeable batteries on hand and they all last about the same. two to three hours.

same experience as you... the battery that it came with (energizer) lasted for just about a month for me.

That's kinda why I'm here. Looking for a mouse with longer battery life. I have this one and I get about 30 days with a Duracell Copper Top and minimal use. I leave it turned on 24/7 though. With Duracell rechargeable NiMH batteries, it lasts almost 3 weeks.

I do not have an exact time that the batteries last. I can tell you that I've used it numerous times and haven't really had any issues with battery life.

I own one and the battery life is only about 1 month. I will leave it to you to speculate.

I''ve had mine for 5 months now. Batteries still indicating more than 50%. I don't think battery life will be an issue.

I've had them HOLD there charge for 4 months of non use! up to 2 months of off and on use and for at the irish fest shooting and video taping 2 - 4 hours depending on how hard I'm going They do hold up well I cannot complain! Those batteries that only cost a few dollares and ya I've tried them! NO.....don't hold the charge for long and don't last that long either. I've had the cheapies go in 2 - 3 years you know freshly charged and Dead in 30 min.
