Newbie to rechargeable batteries. What's the best BRAND of rechargeable batteries? What capacity am I supposed to buy of AA, AAA, C &amp; D (example: C rechargeable Powerex comes in 5000mAH or 9500mAH). What's the difference between Ni-Cd and Ni-MH? Is one...

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

The range of rechargeable batteries (NimH or NiCd) is approx. 0.9V - 1.3V and the range of non-rechargeable batteries such as alkaline cells is approx. 0.9V - 1.6V. So at the high voltage end, a rechargeable is actually lower than a non-rechargeable.Most battery driven devices are designed with the expectation that consumers will occasionally exchange one type of battery for the other. That's kind of the point of having a rechargeable. So yes you can use them without expectation of harm to the equipment, but my experience is that rechargeable batteries never seem to be charged when you need them or after a short period of use, die a lot quicker during use than do fresh non-rechargeable batteries.

Yes, you can use any brand of rechargeable batteries. I have used Sanyo, Amazon, Eveready, and others.

I use Tenergy 10,000 mAh Ni-MH rechargeable batteries. They last just over a month, so I swap them out and recharge once a month - easier to remember that way, and it's cheaper in the long run to use rechargeables.

I'v used rechargeable batterys in mine for over 2 years NiMH Rechargeable Cell: AA Size, 1.2V 2600mAh from www.batteryspace.com/

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.

Yes, Energizer & RadioShack sell AAAA batteries for this pen. RadioShack has a rechargeable version as well, albeit it's very expensive (like 6 or 7 dollars each). The best solution is to make AAAA batteries on your own by "butchering" a regular 9V battery. I was very skeptical about this hack at first. But after doing it on my own, I'm now a firm believer; it simply works - works wonders. Do a Google search and you'll find it in Wikipedia, Youtube & other web pages. Happy hacking!!!

I see this question asked a lot. There are NO "AA" Li-Ion batteries. There are "AA" sized 14500 cells, but they are NOT interchangeable with any type of "AA" cell. Li-Ion 14500 cells have a nominal voltage of 3.7V (4.2V fresh off charge), while normal "AA" cells are 1.5V for disposables, and 1.2-1.4V for rechargeable types (Ni-Cad/NiMH). Putting 14500 Li-Ion cells into anything designed for "AA" batteries will fry the device instantly. There are also non-rechargeable Lithium "AA" cells, like the Energizer L91, and while those are slightly higher in voltage (1.7V) they usually can be substituted for standard "AA" cells. I would only recommend those in devices that take few cells (1-4). For devices that use a lot of cells (6 or more) the cumulative voltage of the Lithium "AA" cells could be dangerous.

Definitely Duracell has good long lasting charge, you want to find the highest mAh rating to get the most out of every charge, though this particular set has been mentioned at 800mAh though i think there is 1000mAh for AAA batteries. Would be nice for Duracell to properly label them. I use Duracell in my mouse and other appliances, have Energizer AAA batteries but i have been looking for some Duracell ones.

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.

They are only 1.2V (all the 1.5V I found are alkaline batteries).For your purpose, I recommend you get the 1.2V rechargeable with the highest mAh. Personally, I would get these:8 pcs of Tenergy C Size 5000mAh High Capacity High Rate NiMH Rechargeable Batteries

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.

Replacement batteries are typical AAA size rechargeable batteries. In two years the technology will probably change, but Li Ion or NiCd are the current rechargeable types. They are not too expensive, it is not a "battery pack".

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

I'm using Panasonic eneloop 2000mah rechargeable, which is low discharge battery and they are still going strong after month. Will update when they need recharging. I used the Maha MH-C9000 to cycle and charge them as well.

4 AA size batteries. Rechargable. One can also purchase these batteries along with a charger,combo pack. Much better deal. I will never use nothing but rechargable batteries from now on. Save lot's of Money this way!!

I use 4 C-batteries. I use Tenergy rechargeable batteries. Use caution in placing the batteries in the flashlight. They have to be in the arrangement specified. This has been a very good flashlight. I use it literally everyday.
