How well does the rechargeable battery work? It seems like most people just use the AAA batteries.

You get approximately double the runtime with one 18650 2500mah rechargeable battery, than three alkaline AAAs that might put out 1000 mAh each. With rechargeable NiMh AAAs, you will have less runtime, but the brightness will stay constant longer, the alkalines have a steep dropoff.

I haven't used the rechargeable battery at all with this light. I think the AAA batteries are better, although they do create more waste so I would recommend recycling them when they have reached their limit. I think the light is great, but I would also couple it with a helmet light, too. Hope this helps.

I found that AAA last longer. And are more reliable to carry spares on the trail

I haven't used 3 AAA batteries with this light, but only the rechargeable battery that came with it. I had the Cygolite Expilion 800 USB Bicycle Headlight and this one isn't as bight as that. It's about as bright as a two battery regular flashlight. It has not gone out or anything, but it has two weakness which is miner. The lens can fall off sometimes and the battery case now gets turned around inside the light. This's correctable and hasn't caused me a lot of trouble. Because it can be used as a flashlight and a bike light it is handy, but if your looking for a light like the Cygolite Expilion 800 USB Bicycle Headlight then this wouldn't do it. I miss that kind of light a lot and someday I might get one again. If you just want to be able to see the road and that's it then this one will do it. Hope this helps you because it isn't easy finding the right headlight.

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 have only charged AA batteries and it does great with those. I have not tried AAA batteries yet.

3 AAA Batteries. I've tried about 6 different brands of batteries, including rechargeable, and they only last a few hours on the bright setting. They will glow dimly for a few hours more. I use rechargeable eneloops and have to change them every day. On the search for a better alternative but may end up with an electric light anyway.

My unit uses one AAA battery, which lasts weeks. A disposable battery works perfectly, but you might try one that recharges in a separate unit.

I use the AAA batteries. They work just fine. Cant beat this item for the price. Well worth it.

AAA **RECHARGEABLE** - any kind will do. I bought a set of Sanyo batteries with a separate charger from Amazon.

I've been using rechargeable batteries since purchasing it about six months ago. Works great.

It has an adapter to use 3 standard AAA's. It does come with the rechargeable battery and the charger as well, but you can use standard batteries via the adapter. I've never tried it so I don't know if there's a performance difference or not.

The EA4 uses four AA batteries. It would probably work all right with rechargeable batteries, but I don't use rechargeables. Batteries were not included with the EA4 that I purchased. The EA4 is a good flashlight for the money. Its only fault that I've found thus far is that it gets very hot - too hot to touch - after being on the brightest setting for a while.

Battery life is pretty good. I like it because it is rechargeable. Just plug it into an outlet.

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.

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!

beats me...i just use regular AAA...i really like the light and got 4 extra for gifts...so far no probs. try a diff brand rechargeable; the chinese sometimes vary in size

I have always used the batteries. They have worked great. It must not take a lot of power to run, because I have used it many many times on one set of batteries. You could get the adapter, but it is really not needed, but it would make a good back up I would think.

I am not using rechargeable batteries in mine. So far the battery life seems to be good. I do keep my camera turned off when not in use. I've had the camera about 2 mos. now, have taken quite a few pictures and still on the first set of batteries. Note: with the 26x optical and 26x digital on top of that this camera takes great moon shots. Looks like they were taken through a telescope. Craters are in sharp detail.
