I read somewhere that the batteries last for about 12 hours. Is there a secondary battery backup for when you switch the batteries?
309150
No there isn't a secondary battery back up. However there are 4 AA batteries that saves the memory.
309151
Yes 4 AA batteries maintain the information you programmed like date, tax, etc. However, these batteries will not operate the register they only maintain information programmed into memory.

My original batteries finally ran out after six months. Most of the time I didn't even bother turning the switch off at night. Amazing battery life!

I just change the batteries and don't bother with the other stuff. batteries last anywhere from 2 weeks to 3+ weeks depending on how much I use it.

Sometimes it takes 12 hours, I bought 2 battery packs, They last me about a week of riding for about 40 minutes every morning before I have to change. I leave them plugged in to the light so there is always a bit of current draw even with the light off. I have ridden for > 3 hours on a charge and still used it the next day. I really like this unit even if it does take 12 hours to charge.

I've had a couple of these and even when new I don't get more than an hour out of a charge. Currently it's about 30-45 minutes. I've never found the batteries to replace the original and my belief is they aren't replaceable. I just buy another WLB26B since they are relatively cheap and I like them because of the light output.

It would be safe to say 8 hours, but it lasts a long time. There is no worry in the battery department!

I purchased a couple back-up batteries online just in case, since I would be in remote areas while shooting. A fully charged battery is good for about 260 min. I shot about 200 photos a day, and about 30 min of movies without ever having to go to a back-up battery. I thought battery life was very good. Best to stick with brand names, or reliable sources though when purchasing back-ups, as I did end up with 1 battery that would not take a full charge.

I've had mixed luck with replacement batteries, and it's not necessarily a "get what you pay for" scenario. I'd say the "bad" replacement batteries I bought probably gave me an hour of actual run time, whereas I've had good replacement batteries give me at least 4 or 5 hours, maybe more. I mainly use it for less than 10 minutes at a time, so it's hard to judge the run time I get out of batteries. Either way, replacements are small enough and cheap enough to just keep a few on hand at all times.

I don't know if you are referring to the battery or the camera? I find the battery does not last long, which is why I bought this additional battery as back up. I keep it with me while I am photographing. If you review your photographs on the camera after you take them, it uses up a lot of battery power, so I do not do that. Depends upon how many photos you take. If I am out all day photographing, the battery might last for one day.

Sorry I missed this. My wife uses it and says she has 8-20 hrs and still the same batteries. Said she loves it though !! Hope it helps

A couple of hours with regular use. I ended up getting a second battery and that's been great, but not necessary if you charge it regularly.

Hi The Battery is for backup. Its good to replace the battery after 2 or 3 years. Very simple to do. It is a Great switch.

On the day that I received both, I immediately put batteries on them. I used the first one and stored away the other. The longest I've stored the other one before using it is around 20+ days. Didn't notice any difference in brightness compared with a newly replaced battery.Ideally though you won't store batteries in it for long periods of time (e.g. months or more) because of possible corrosion or battery leakage. Of course that also depends on the battery quality.

I have had mine on about 12 hours of use. Still have the factory batteries in it. The camera batteries going dead is the problem I run into when do time lapses.

I haven't really gauged how long the battery lasts; much depends on flash usage, video vs. stills, etc. But, the battery in my new camera out lasts its predecessor, and I don't even give battery life a second thought. If you're worried, get a second, back-up battery.

You shouldn't have to have a backup battery. These batteries last a long time. And you only need one if you have the phone service

The battery lasts for several hours of continuous use. I did buy a backup battery as well. It ends up being a race between running out of battery and running out of storage memory. I've set this up on a tripod and recorded continuously for at least 2-3 hours (possibly longer...I did a 5 hour recording but I can't recall if I changed batteries mid-way or not). I also highly recommend getting the water-resistant housing (clear/orange)..I've used it to dive to 80ft.+ and it's repeatedly worked great. That housing also serves as a tripod mounting point. Hope that helps...feel free to ask any other questions. The battery lasts for several hours of continuous use. I did buy a backup battery as well.
