How long do the batteries last?

I had my scale for 5 months and I need to change the batteries. I would say my use was typical.

The battery I got didn't last too long. About 5 or 6 months. Perhaps a fresh battery would last longer though!

I've had mine about a month now and I've used them for at least 20-30 hours while in the backyard on battery power. The sound is good, the range I am using is about 50 feet with minimal attenuating materials between (walls, doors, etc). I'm not sure how long the batteries will last. You can probably do the calculations based on average current draw and the capacity of C sized cells.

the battery life lasts approx 4-8 hours...sometimes longer if not used continuously.

Not long, had to buy an extra 3 pack of batteries to keep on hand. Never leave home without an extra one.

depends on your weight. 3 or 4 hours for me when batteries were new, but unit is cheaply made and doesn't last long.

9 to 10 hours depending on setting and batteries used. I usually get at least 9 hours using rechargeable batteries.

The batteries with intermittent use, lasted about 4 1/2 to five months. It may have been a bit longer, but no more then 6 months. I don't have any complaints. The screen shows enough detail with a night light outside.

They are water powered, no batteries so I guess they last as long as the LEDs. Probably a really long time given most LEDs last over 40,000hrs.

I've had mine about a year and have not replaced batteries. But it depends how much you use it.

I personally do not knwo as I used them for a teaching aid in a project but depending on what batteries you use they can last anywhere from 24-48 hours continuous (LEDs on). The consumption on it in standby mode is very little (~70 micro Ah) so depending on if it is placed in a high volume traffic area or not will also determine how fast the batteries deplete. The consumption when it is on and lite is ~70 mAh.

I have four of these, all installed since 9/2013. One of the batteries died after about 6 months, which kinda worried me, but the other three are still on the original batteries and still sound loudly when tested. So, 6 months to at least 17 months. These are nice little units, worth a few extra bucks for the small form factor.

Really couldn't say - I use these infrequently. I will use them nightly for a week or two, then turn them off. Only use them on dark winter evenings. Still using the batteries from last year, therefore. So - I will hazard a guess that they last a long time, maybe several months if not used daily.

Wel we don't run the lights all the time so I only know that I have only changed the batteries once so far. We run them when we have guests over. It appears that they last pretty long though.

I use them alot , most of the day in fact, and I can get around 5 hours (talking on Skype and listening to Youtube videos) of use out of them before they need recharged. They take about a hour to recharge ( I just use them with the charging cord plugged in)

About a good 6 hours maybe 8...I bought them as a Christmas gift for my two kids and to be honest I don't allow them on longer than an hour but my husband used it for 6 hours straight. Pretty good product I honestly can't complain.

Can't give exact time but they last pretty good time. They use reg AAA batterys.

4 to 5 hours I believe... depends on what your doing with them, constant music shorter battery life...
