I recommend ENELOOP brand rechargeable batteries. They will last years on the shelf losing very little charge.

I liked the first one so well, I bought a second one, and I'm a happy camper!

Howdy Becky, These are a lot larger batteries that a normal "AA" battery. Normal "AA" are 1.5 volts, These are 3.7 volts. But they can be found on Amazon by typing in 18650 Batteries. Don't buy the cheapest you see Nitecore has a set of two with a charger for about $15 Prime. I have a set of these myself and they last about 8 hours while fishing. Once a month I let my light run completely down. Then I charge it completely. This helps the battery from developing what is call a discharge "memory." If you charge everytime it goes down to 1/2 time, the batteries will start to think 1/2 discharge is fully discharged. Hope this helps you out.

You can put any brand of NiMH AAA batteries in your cordless phone, and your phones won't know the difference. Phone makers always tell you to use their own brand, for obvious reasons.

My pack of AA purchased in January 2015 says 2014. I did not know NiMH goes bad 3 - 4 years. How did you find out this information? I have been using rechargeable batteries for years with no problems without NiMH. I just checked a different package of AAA purchased in January also & it says 2011. Gee your never too old to learn a valuable lesson. Thanks so much for informing me about this. Have a great day. VRLT

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 assume "regular" batteries refers to 1.5v alkaline batteries. Using a battery tester and a high-end volt meter I've concluded that each recharge results in a bit less energy than was true of the original "new" charge. How long a battery "lasts" depends on what you are using it for and how much the appliance you are powering is used. Assuming the same appliance/use, you will need to recharge sooner each time. This is also true of 1.2v rechargable batteries (Ni-Cad and NiMH), but their chemistry allows for recharges closer to the previous one and many, many more recharge cycles. I figure 4 alkaline recharges is about all I trust. After that the chance of equipment-damaging leakage is greater and a recharge may get you 50% or less than the original 1.5v capacity. NiCad and NiMH rechargable batteries can go hundreds of recharge cycles.

I wanted to purchase these also for mitsubishi dlp, but seeing as they have disposable batteries ,I will opt for the rechargeable NX-3DGR from same company. Those(nx-3dgr) state for mitsubishi , so i will get them and not play the guessing game, why do they have to make life more difficult i say.

6 real c cell batteries. Do not use rechargeable "c"'s. They are AA's in a larger sleeve and will not last. There are some true "C" rechargeables that rate over 4000 Mha, but they are expensive. I use copper top C's.

The batteries are known as 18650 and are amazing and rechargeable. Usually located in the "customers also bought these items" section. It's a great light. Durable/tough, bright and is available in 5 Mode, which I would recommend. Also, definitely prefer this over the 502b, which is just not as rugged, but would be lead to believe it is newer and better as it is a higher number. Not sure but off topic.Great light 18650 are the batteries it needs or you could use VERY expensive 2 x cr123 non chargeable batteries. WASTE OF MONEY. GO WITH A PAIR OF 18650 AND A CHARGER for about 10 bucks! Hope it helps. The batteries are known as 18650 and are amazing and rechargeable.

With my MB-D200 I carry the charged EN-EL3e as a spare and 6, 12 or more rechargeables (depending the assignment) These are 2500 - 2900 mA NiMH and generally last more or less as long as the proprietary battery. I have not seen much performance difference between expensive and cheap ones, but I guess the cheap ones will just die sooner (well, maybe not...) In the case of the MB-D10 of course, you would have to pack multiples of 8. Anyway, I always carry a box full of charged NiMH's, because I have to "feed" the flashes as well.

Dewalt has 2 battery types for some of their 20volt Max system tools and label the differences with the letters C, L, D and M for the sets. The tool alone has a B designation. The regular Lithium Ion batteries are labeled C (1.5Ah) and L (3.0Ah). The XR batteries (33% more capacity) are D (2.0Ah) and L (4.0Ah). I own the DCF895C2 set and it is an outstanding tool. Also you need to consider the weight of the battery. The 1.5Ah and 2.0Ah weight 0.8 pound. The 3.0Ah and 4.0Ah weight about 1.4 pounds each. Take into consideration the fatigue factor with the heavier batteries. Dewalt now has a 5.0Ah battery at the same weight as the 3.0 and 4.0. You have a lot to consider with the 20 volt tool system. I am happy with each one I won.

I prefer this AAA battery set, they last months before having to be replaced. The newer built-in rechargeable battery set i believe they advertise as having a 24hr battery life before having to be recharged. That made my selling point the AAA pair.

I also use SONY NI-MH batteries and I haven't experienced any problems. I think what they meant to emphasize was to use NiMH type of rechargeable batteries. Here is what Olympus recommends: Ni-MH Quick Charger and Battery Set (B-90SU) http://www.olympusamerica.com/cpg_section/product.asp?product=1393&fl=5 "What is the difference between Nickel Cadmium (NiCad) and Nickel Metal Hydride (NIMH) batteries? Both NiCad and NiMH batteries are rechargeable. The main difference between the two is the fact that NIMH batteries offer higher energy densities than NiCads. In other words, pound for pound, NIMH delivers approximately 30% more capacity than its NiCad counterpart. " Reference: http://www.batterymart.com/c-battery-facts-faqs.html#lith-alk

I have tested AA and AAA alkaline and rechargeable up to 2500 ma in rechargeable. I have also used it with the CR123 3v lithium that my flashlights use with very good success. I have not tested any other batteries so far. My AA rechargeable batteries are the nickel metal hydride type. I have not tested the older nicad type rechargeable.

A Nickel-Metal Hydride cell (NiMH) is a specific type of rechargeable cell. The specification describes its' physical and chemical properties. The AA size cell is the same physical size in any type or brand. Chemically, a NiMH cell contains the same chemical makeup although different cells could be physically different inside. Different brands of AA NiMH cells can be used together. However, I would hesitate to intermix those with different mAH (milli Ampere Hour) ratings due to the difference in discharge rates and recharging rates. If all the AA cells have the same Specs. (That is, New, NiMH, 1800 mah, for example) they should perform as expected. (Be aware that the Specs. on some cells are overstated.) Don't mix new ones with old ones. Don't mix NiMH with NiCD (Nickel -Cadmium), alkaline cells or any other type. Also, you didn't ask but don't mix different size cells of any type whether series or parallel connected. When it's "all said and done", there IS a difference in brands. Some are just better than others - probably due to greater care in the purity of chemicals and manufacturing. All these things considered, I believe you can safely use Eneloop NiMH AA's with Amazon Basics NiMH AA's of the same mah rating without any problem. I wouldn't hesitate. I hope this is helpful.

According to the instructions enclosed in the packing, Ni-MH rechargeable batteries are recommended for replacement. I have not had any problems with the ones I have as of yet but the rechargeable solar batteries can be purchased at stores like Home Depot and Lowe's and most local stores as well.
