What is the approx. burn time on rechargeable batteries like the Eneloop 1,900mAh? I need a light that will last about 2 hours on a charge for long night dives.
don't really know, i don't use those batteries
but it should be fine
it should be okay for the battery actually. but each dive you need to change the battery. I'm okay for 1.5 hr dive staying for shallow water photography. But for me this light is really not durable due to the battery removal method...the way to change battery makes the geometry easily wear and once it was worn, it stayed dead. And you just need to change battery so often....
Five hours and still going per my test. Thanks for the suggestion. I will take the rechargeable batteries with me on my next dive trip.
I had reg batteries for the whole week. Use the light evryday on all my dives, including 5 night dives. Light was still going strong.
I put at least 4 hrs of burn time on mine using standard alkaline batteries on a trip to bonaire and would not have hesitated to take it on another. It was still very bright. I don't have the answer to your specific question regarding rechargeable, but I personally would not recommend using rechargeable batteries. The brightness is noticeably lower with rechargeable batteries due to their lower voltage. Hope that helps.
I have never run out of battery yet :-) I usually replace them about every two years or so before a bigger divetrip. Between I also use the light repeatedly when I go offshore sailboot racing. So I'd say you should definitely get tow hours.
I use Tenergy NiMH 2600mAh batteries, and I haven't experimented with any others. But I just put 4 freshly charged ones into my League 100 and ran it for 2 hours in a tub of water, to keep it nice and cool. It was a bit dimmer at the end of 2 hours compared to first turn on, say 70-80%, but still seamed to be putting out plenty of usable light. This little flashlight puts out tons of light for its size, James. And battery curves are funny; your 1,900mAh cells might very well keep a higher voltage during discharge compared to my 2,600mAh cells.
THANKS! I have Tenergy (and Eneloop) AA's. I thought the Tenergy were 2500 mAh, but I could be wrong. Anyway, your test will cover the longest night dive I've done and am likely to do, so thanks again for the information.
my pleasure. just remember, this is not an 8 c-cell flashlight. you are going to get good distance spot lighting and good up close lighting, but not the sort of area lighting a multi-LED high-cell-count lamp gives. that being said, it's my favorite non-headlamp flashlight due to its small size, good power, and rugged design; i use it for backpacking, night fishing, investigating things that go bump in the night, and everything else besides using it for diving.
Sorry! I have no idea. I only used it with disposable batteries.
I use Sony 2500mAh rechargables and it easily lasts 80 minutes. Never tried 2 hours. That seems too long for 4 AA.
Thanks, Keith. 80 minutes will cover 95% of my night dives, so that's great to know. I assume you're happy with the Sony batteries?
The Sony batteries work well. One note about the flashlight. The shape fits your hand well but you do need to fully insert the lower two batteries before inserting the top two. It will get stuck if you don't push the lower batteries into their place. Once you know this, the flashlight works very well and is surprisingly bright.
Good question. I have this light and the batteries. I will have to try it.
I'm not using rechargeable batteries but with regular ones the burn time seems fine. Great light for the $$$. Easy to carry great light. I don't think you could go wrong.
