Aa Alkaline Rechargeable Battery Price

For the price of two brand name alkaline 9V batteries you can buy one rechargeable one. The math is clear. I also find it handy to use a fully charged 9V battery for an electronics project or a device that requires 9V. The electronics (but not attached servos) of an Arduino project can be powered with this type of battery. The Watson 9V charger charges two batteries simultaneously.

Solid Light - good to keep in my truck. I like the Dual Power. I keep the rechargeable in the light but keep the alkaline battery pack handy so I can use the light while I recharge the battery outside of the light. Nice and bright.

This is a great emergency light. Comes with a solid rechargeable battery AND the alkaline battery cartridge. Dual power is a great feature. Anyone who has run out of power or had a rechargeable battery reach end of life knows how important it is to be able to switch to alkaline power.

It's good to have a battery testing on hand and this one does the lithium and alkaline batteries. One thing I would note is for rechargeable batteries that have been handled a lot; it a good practice to clean terminals with  isopropyl alcohol otherwise it could give inconsistent results. This is covered in the manual and in their FAQ on the website. It is not readily apparent as to why you would need to read the manual for such a straight forward device :).

What a great little flashlight! I like the versatility of having a rechargeable battery or Alkaline batteries. I do a lot of off-roading so the compact size but powerful beam makes this about the perfect light for me. Since our last night ride, two of my riding buddies have bought one each for themselves.

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]
