24V Rechargeable Battery Pack Nimh

[0.06 lb] -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.

[11.1 VDC] I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.

[1.2 V] I have been using Watson MX AA NiMH Rechargeable Batteries in my Canon 600 EX-RT II Speedlite for a couple of years now. They seem to last longer and hold full charge longer than other brands I have used in the past.

Awesome flash light love the rechargeable battery pack and cable

[Steel] I purchased this battery pack to replace an other one that used a rechargeable internal camera type of battery that would no longer hold a charge. To replace the battery was more than this unit cost. Love the fact this pack uses good old fashion AA batteries. Works perfect for my needs.

[Multiple] Product is much lighter than my rechargeable battery pack. I bought it because I can just switch out the batteries if it starts to run out of juice as opposed to having to recharge its battery. Maintained good connection with my Canon flashes-600 EXII-RT. It increased my flash time immensely and I feel much more confident that my flash will continue to fire with it. I have 3 600's and they all fire much better with this battery pack attached.

[0.185 lb] Great light but getting the rechargeable battery will make you use it so much more often.

[Yes] I love the fact that the battery is rechargeable!

[1] This is more than just a charger for your AA/AAA NiMH batteries. The condition feature lets you monitor the health of each battery while keeping them in tip top shape. That way you can revive some batteries that are no longer behaving they way they did when they were new, and remove from service batteries that are no longer holding a full charge. The only downside I've found is that it may not work with some non-Powerex batteries, -you may get a battery fault indication when you put them in the charger even though those batteries will work just fine in a conventional charger. This may be caused by batteries that have an internal impedance/resistance that's different from that of Powerex batteries.
