What would be the average/approximate battery life of the two AA batteries requires? Days? Weeks? Months? Is the expense in battery upkeep reasonable?

I would say at-least a month. The upkeep is reasonable. They are a good deterrent. I have enjoyed them to help with peace of mind.

Ours lasted about a month with average batteries. However when we went to change them as the piece twisted off so did the wires. So it's non working. We never attempted the others. I left them up because they look impressive but no flashing lights anymore.

Should be about 3 yrs. Runs on 2 common AA batteries. The unit comes with 2 energizer lithium batteries.

I believe the description says about 100 hours per battery pair... but I havent used it that long yet...

My batteries last a month or more. It all depends on whether your wiring gets grounded for a period of time. I am basing my reply on a garden wiring around eight raised vegetable beds.

I actually don't know yet. We have had ours in use for about two months now and we are still on the first set of batteries. It has slowed down a bit...but it is still functioning at two months with the first batteries. It is in a bathroom on the ground floor of the house that gets quite a bit of use from family as well as friends and visitors. I was actually thinking over the weekend that I should pick up some AAA batteries because we are probably close to needing a change.

Battery size two "AA". Not sure on duration. I try to use Energizer Advanced Lithium.

I get around 8 minutes of flying time with the standard batteries. Life shortens with dramatic maneuvers - rapid altitude, extreme banking and reversing, etc. Larger amp batteries are available, but I don't have any experience with them.

It takes 4 AA batteries. I didn't use rechargeable batteries, so I don't know how long they would last. I did put some fresh batteries in my daughters about a week ago and it's still going strong. She uses it for about an hour at a time and usually every other day. I have found that it doesn't "eat" batteries.

I put fresh batteries in before a trip I took for 14 days & I ran it every night. The batteries are still good but I am taking an extra set of 4 with me on the next trip......just in case!

The recorder uses two AA batteries. I've had the same set in for a couple of months and they are still at half charge. I haven't used them for six hours straight, but I would think they would last. At any rate, AAs are cheap; when I have a project where battery life is critical, whether for microphones or recorders, I just put in fresh batteries at the start of each day.

A couple of hours on the initial charge when you first get it. Once you start to use it, you can probably expect the same, depending on the amount of charge needed. Regardless of the time required, I've always had a second battery to work with on shoots. It's a good investment.

Ours uses two AA batteries. On the lithiums, our will run around 3 hours of constant use.

The one I have uses two AA batteries they last for months but will discharge if the u nit is not turned off.

Rommel, I agree with Tim. It depends on what you are going to use the stored power for. For example, on average you will charge the batteries 10A for six hours or 60aH. If you are running a water pump that pulls 5A for 15min every hour you would need approximately 30Ah to run 24/7. In this case one battery is more than sufficient. In my case I run LED worklights and cameras. I pull about 10A for 8 to 10 hours which adds up to approximately 100Ah per day. Taking battery degradation and the fact not every day is 100% sun, we use two batteries. Hope this helps with your scenario.

It takes 3 AA cells. Sorry, cant say how long they last-- so far it's only been used with the AC power supply.

We still have the original batteries (3 months) but our use is not regular. We use the radios when husband is working in yard and I need to stay in tou with him, so a few hours a couple times a week.

Tough to answer. Length of time in use and volume will impact batteries. I often use it 4 hours a day and they last about two weeks.
