I put batteries in mine 3 months ago. I've only pulled my trailer 3,000 miles, that's about 60 hours. Batteries are still working fine. Keep in mind that the monitor has auto shut-off if it doesn't feel vibrations of the road, I've had mine shut down while stuck in traffic jams. The unit also comes with a cigarette lighter plug.

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!

Contact the seller. The battery ought to last at least a couple years even in heavy use and the seller may send you a replacement or at least sell you one at a big discount. If not there are a number of good sources for batteries on amazon. Look for a 4-5 star product from a 90%+ seller if possible.

Well let see.... I don't remember every changing the batteries since I put them in place, so if you can see when I bought them, not since then. Thanks for reminding to change the batteries. I do test then so I know they still work. One has saved me a couple times.

I used the expensive energizer batteries. The ones that cost like $10-$15. They lasted me a long time even if I'm turning the camera on and off and adjusting settings. I had a set for about a month or two, using them for birthdays and Christmas. I take photos of my kids and those batteries really held up in that camera.

I have had excellent results with these batteries, usually lasting 5 days or longer. Maybe have had one dud in the year I have been buying them.

The first thing is to check your batteries. Replace the with a good brand, like Energizers. They usually come with off brand batteries, so I put good ones in and they last.

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?

They last quite a long time, actually. I use NiMH rechargeables, and it's usually several months between recharges.

Mine are still working, had them almost a full year. After about a year's worth of continuous use these type of batteries start to go south. If you've used them regularly enough this may be the case. Occasionally there are defective products however.

Have only had mine a little over a year, and I don't use it daily. The batteries still seem as good as when new. They hold a charge even when I leave them unused for a week or two.

In the long-run, yeah. I got a pair of batteries hat worked completely normal compared to other reviews and they worked great for a couple of months. So, if your thinking of buying this, just remember these batteries don't last 6+ months with a good charge.

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....

I don't leave them on all the time but at least 20 to 30 hrs prob more. They are a common size flat battery easy to replace and has like 3 settings of flashing and one solid. My batteries havent ran out yet.

They last pretty long. Make sure you use quality batteries, like Duracell or Energizer. Don't forget to turn them off when not in use. I don't want to attempt to guesstimate how many hours, but we really don't have to change them often. If they start making funny noises, time to change batteries.
