What's the recommended recharge current for the AA and AAA? I'm using a lacrosse bc-700 with three possible charge settings: 200mA, 500mA or 700mA . According to the lacrosse manual 200mA is generally suggested, but this is slow, 13 hours for AA. So i...

For charging AAA cells (with capacity ~800mAh) the default 200mA setting is ideal. It gives roughly 4 hours of charge time. For charging AA cells (with capacity ~2000mAh) you should NOT use 200mA. Using a low charging rate of 0.1C (200mA/2000mAh = 0.1) means the charger may miss the main 'negative delta-V' termination signal. So it will over-charge the batteries until secondary termination signal (either over-voltage or timer expired) is detected. This is bad for battery lifespan in the long run. The optimal charging rate for a smart charger is around 0.2 - 0.33C. That means charging current of 500 to 700mA, which gives 3 to 5 hours of charge time. Some people will tell you charging at 0.1C is the best for battery lifespan. That is a left-over from the old days of dumb chargers, where people just blinding charge at 0.1C for 14 hours, regardless of battery status.

I haven't seen the information that you are talking about, but if you Google AA 18650 eneloop, what comes up is a Sanyo battery charger, that will charge AAA and AA batteries.Simon recommends that you use rechargeable batteries, and that particular brand is supposed to discharge slowly (an issue with rechargeable batteries is that they discharge even when not being used). So I would assume that they are recommending a particular brand of rechargeable battery, rather than saying you can use an AA battery.

I have a La-Crosse BC-1000 which I have used to it's fullest potential. It's a very intelligent and powerful charger allowing you to charge at different amperages (higher for quicker re-charge and lower for a better recharge) as well as being able to completely de-charge to eliminate battery memory issues that don't allow a full charge. You can charge AA's and AAA's at the same time and each of the 4 positions is independent of the other. In other words, when one cell is charged, it will discontinue charging the fully charged one and continue charging with the rest and so on. There a little spendy, but to get the most out of your batteries for years of use, it's a great charger. I have a La-Crosse BC-1000 which I have used to it's fullest potential.

rechargeable batteries come in different strengths which determine how long they can hold a charge and how many times they can be recharged.2500 seems to be about the strongest and they go all the way down to 600. try getting some 2300-2500 and see if they last longer. the number is listed on the side of the battery and somewhere on the package label but in very small letters. 4 AA batteries of 2300 mamp rating are under $10 at Walmart.

AAA batteries cannot be recharged at all, period. Unless they are re-chargeable batteries. The XTAR charger is built to re-charge hi-drain special purpose batteries @ .5 - 1.0 amperes to 4.2 Volts. This is NA for AAA and AA multi-use batteries as they are 1.5 volts.

3 AAA per light. If you are going to have these on for long periods of time I highly recommend also purchasing the Amazon Basic AAA rechargeable batteries and a charger. The price for rechargables and a charger will more than pay for itself over the long haul. The batteries will run the LEDs for around 100 hours, but not a full brightness, as the power drains down over time so will the light output. For occasional on off use, such as turning one on as a hand held light, or for use in a cabinet or safe for a few minutes at at time, the batteries will last months (I have had mine in my safe for eight months and they are still going strong) One nice aspect of these type of puck lights are the ease at which you can access the internals - in my case I like to have one with magnetic tape on the back to attach to the outside of the safe to see the key pad, or combination lock. I do not want to ruin my night vision so I access the internals of one, and color over the LEDs with a red marker pen. This makes the light output red of course which is much better if you want to remain in a somewhat dark condition, or are going back outside into the dark where you want your night vision in tact. Magnetic tape strips, adhesive on one side to stick to the back of the light are easy to find, most likely if you do not want to buy some just use an old refrigerator magnet and stick it on to the back, with the magnetic side clean and facing out it will stick to a metal safe. The inside of one safe I have has three shelves, each metal, I keep one on the underside of each shelf and turn on as needed, with one left to be white light for use when I do not need to keep night vision. Sorry for the long run on, trying to put to much extra information into this.

AA -- Original answer. Revised answer - I should have said two AA batteries. Sorry for the poorly worded answer. Since purchasing the camera, I have invested in a battery charger and a set of rechargeable AA's, which will pay for themselves over time. The charger also works with AAA's which I use in other applications.

I am not familiar with LaCrosse BC-700. What I have to charge my batteries is an AC charger with output of 4.2v 600 ma DC.

AA's usually run around 1800-2000mAh where as AAA's usually run around 700-900mAh for the given chemistry. The difference between 800mAh and 1000mAh is the 1000mAh is going to last ideally 25% longer in a given application. Say an MP3 player runs for 5 hours on the 800mAh. In theory, it will run for about 6:15 on the 1000mAh batteries. Actual time between charges is going to vary depending on many things such as volume, temperature, etc.

The issue is charging current, as the charger doesn't sense capacity. If you only charged one AAA, the charge rate would be too high, .75 mA. This is why the instructions specify that at least two AAAs or 10440s be inserted when charging.

The Laser contains 3 AAA batteries (metal hydride). I am in North America, so the charger runs off normal 110 - 117 Volt AC house current when charging the Laser.I use my B-Cure about 40 minutes twice daily on a few areas on the anterior face of my Knee with the knee bent 90 degrees and resting on a large pillow while I sit.This 80 minutes per day use means I have to charge it each night. It will provide perhaps 100 minutes, but, I like to keep it topped up each day. The battery half-drainedsymbol flashes at around 80 minutes of usage.

4 AA's just realize with the cost of the batteries, you might want to just get 1200mah ni-cad rechargeable's. Depending on use they should last a full year and to recharge only takes about 2 hours. It is not stated in the description, but the mixing valve is included.

Charge time is determined by the capacity of the batteries divided by charging current. The charging current of EBL 808A is very low at 200mA. So to recharge a pair of 2800mAh batteries at 200mA will take at least 14 hours.

I've been using 2 AAA Ni-MH rechargable batteries in it. Can play continuosly for about 48hrs before changing them out. Getting the batteries out of the controller is kind of tricky but can be done with no harm to the batteries or controller if you take out one with your finger nail and gently bang the other one out. Ni-MH AAA batteries with charger is fairly cheap.

The charging current is 300mA. So to recharge a set of 2000mAh batteries will take about 7 hours (2000mAh/300mA = ~7h). Shorter if the batteries were only partially drained.

Hello, I have the Duracell 15 minute charger that charges AA & AAA batteries, and that's the highest powered charger currently available that I know of for Duracell itself. The power output for the 15 minute Duracell charger I have is 1.2 volts for AA & AAA batteries and 8.3 Amps(current) max for AA and 3.5 Amps(current) for AAA, so if your charger outputs more for voltage or current for AA & AAA I would recommend not using it for those type of batteries, and as far as other batteries like C,D,9 Volt, etc. I can't recommend since my charger doesn't charge those types of batteries and only charges AA & AAA. If your batteries fit into your charger and the output power matches or is slightly under my power output then you should be fine, and anything that charges at a higher power output should not be used since Duracell hasn't made batteries and a charger that can handle higher output power charging yet. Good Luck!, bye &#9685; &#9697; &#9685;

That's one downside here. AA's are too small. An alternate is the C123. That will be a pricey alternative because the XMLT6 will gobble them up. Go with the rechargeables.
