Aa Rechargeable Battery Mah Ratings

Higher mAh rating yields longer usage time than most other rechargeable.

I appreciate that this battery pack came with two ways to use it. To put in AA batteries or to use the rechargeable batteries. Love the thought process in the details as well. Having a shutter button on the battery pack makes up for adding bulk to the camera. Yes this is my first battery pack I have gotten.

-Superb battery life (At 100mw, I get over 8 hours with a pair of rechargeable 2400mh NiMh AA. It will go 14 hours if using lithium AA!) -Excellent sound quality. -Unrivaled reliability. -Smartphone App lets you change settings via dweedle tone. I love the newer, darker finish on them.

Really great, you can run the camera off a 2nd rechargeable or swap the AA battery tray an run it off them.

Like this head light very much. It is still on the AA batteries it came with and I have the rechargeable battery fully charged and waiting for use. I bought this because my son has taken my older one for his own use. The only downside is it has no port to recharge the battery. So I put it in my older one for a charge. BUT I LOVE IT......

I'm a big fan of rechargeable batteries. Saves a ton of money in the long run. This charger and battery combo is perfect. I love the big LCD display. It lets you know the status of the battery and charging levels which is very helpful. I've had other chargers in the past that would just blink, or give a red/green light. Having a descriptive display is so much better, as you can gauge how much power is left or how much more needs to charge for the batteries to be ready. This is vital. It can also discharge the battery to refresh them. This is also a very handy feature to extend the life of the rechargeable batteries. It will not only charge AA but AAA batteries and I plan to get some AAA's to partner with the AA's that came with this. The batteries themselves work great and last a long time. I'm very impressed with the power and time they give. [I have received this product in exchange for my honest review]

The keys have a nice feel. I really like the internal rechargeable battery, instead of having to swap AA batteries like the older model.

Lets you connect 6 AA batteries and power the Tascam recorder through it's charging port. After you've gone through a rechargeable battery and the onboard AA batteries if you didn't have a second rechargeable battery, this is an option. 6 AA batteries should run the 100-MkII for about 4 hours according to the manual. This connects to the back of the recorder effectively doubling the depth of the unit (if you attach it) and connects through an included (believe it or not) cord that is about 4 long so you could lay the battery pack beside the recorder if you wanted to. Unless you are recording a day long concert, you're probably not going to need one if you have two rechargeable battery packs on the 100-MkII. Likely more needed on the other recorders that don't have the ability to easily change from one battery to the other. The only reason I am not recommending it is that with 2 rechargeable battery packs on the 100-MkII, having this as well is really overkill. I could have saved the money and been just as well off.

I’ve been using quality rechargeable AA batteries for years in my speedlight but these are by far the best! Quicker refresh rate, longer lasting than any competitor battery. I recommend this battery as a great replacement and you cannot find a better price in the world than B & H

I have spent more on AA batteries over the years that was probably twice as much than this rechargeable battery cost. 3 days on the trail cam so far and still going strong. Wish I knew about this item years ago.
