About how long do the batteries last? Has anyone tried the solar panel with rechargeable batteries?

I feed mine 5 seconds twice a day. Pits out plenty of corn. Batteries last about 3 months. I use Everyready lithium AA

several months on 2-3 seconds a day on alkaline batteries. recently I tried the Eveready super lithiums. worked fine until the cows turned over the feeder so I don't know how long they will last.

I don't know about the above buyer but it works well for me. As for rechargeable batteries, I don't see why they won't work. The unit uses 6 AAA type, I use Duracell/Energizer, and can get about a full month of use with them on for 30-40 mins a day.

I think there is a 50/50 chance you could get it to work - But it puts out more than your smaller panel. I think other posters recommendation to check batteries is a great idea - every solar light I ever purchased, the batteries are what failed, not the solar.

I run mine on a 12 volt battery for 20 hours with no issues, I would think the right solar panel would work.

We usually don't use ours for more than 90 minutes of continuous use. They could probably hit 2 1/2 hours with a decent battery, but it might be a stretch. I don't know if you need them to run continuously for the whole time, but we try to conserve power by turning them off when not actively in use. We're running them on Energizer rechargables.

I have found it best to run a 10 watt solar panel and double the battery size. If all goes ok I can get about 2 years out of the battery. As others have answered, if the sun is not shinning the solar panel is not charging. When we get an extended period without sun I will pull the battery and charge it with a battery charger

I've only had the system for a few months, so can't speak for long-term use. The instrument array has a small solar cell that charges an internal battery. The inside console uses three "C" cells or a supplied transformer. The accompanying owner's manual suggests the "C" cells will last for about a year.

Greetings. Theoretically speaking, the batteries can last 100-120 hours. But it will also be affected by the battery type and usage. Thanks for your question.

Mine works fine using the solar. I did notice the charge doesn't last long after the sun goes down though.

I used the 200w report solar panel system to charge that batt. 3 of us ran laptops and phones as well as a heavy water pump and the solar panel kept it full almost always. Did this for 17 days. I'm not sure how much AGM batteries are meant to deep cycle though so look into that.

Yes, they require two (2) Rechargeable AA batteries. The Solar panels provide power to recharge them daily with adequate sun.

My experience is that they do not last "a year", but it's only 4 AAs. My rechargeable ones don't seem to last as long. If battery life is a concern, why not just plug it in?

The hubby and I use the Energizer E2 batteries. We haven't had good luck with rechargeable batteries. But the E2's last a long time compared with other batteries.

We did not try rechargeable...but the batteries only run the LED light, for using the microscope at night or in dim settings, so I don't see why rechargeable wouldn't work. Though rechargeable batteries' top power levels are never quite as high as non-rechargeable, I don't think you'd see any difference in light levels, since LEDs take so little power to run. Any difference the lower power levels made would likely be in how long between battery changes, instead.

I have never used rechargeable. But it seems to work very well with the normal batteries and last a long time. I put batteries in my radio in Jan and they still are good at the end of March. I've been putting the radio on a little bit almost daily.

Yes I see no problem utilizing rechargeable batteries. Hope this helps. Very useful light.

I don't think the solar batteries can be recharged that way but I'm not sure.Maybe contact the battery company and ask them.
