With these - I only use half as much!
on March 5, 2014
I mainly use these in a wireless guitar setup twice a week, every week.
The higher power that these batteries provide allow me to make it through the night using only one battery, whereas I had to switch mid-way through the gig with the other rechargeable batteries.
500 mAh -although twice as strong they are quite strangely very light in weight. Maybe one-third the weight of conventional rechargeables. Very odd. Who knows WHAT types of elements they are putting inside these things these days, but they work wonderfully.
I have used the Tenergy "blue" or regular type batteries for over two years without fail.
I have saved hundreds of dollars and have rewarded myself thusly! -lol.
They do tend to discharge a little when stored, so if you want them fresh and full, make sure to charge them right before you use them.
The guide says it can take up to ten hours to charge these, but since I don't completely drain them I find that in about 3-5 hours they are fully charged, or at least the green light comes on the charger indicating full charge.
If you are only charging one battery, then it may take much shorter time to fully charge.
I try to remove them as soon as I see the green light come on, because I feel that the charger automatically shuts off and does not keep them trickle charged fully, but I could be wrong.
As others have mentioned, there is only one light on the charger and the "other" one is a "dummy" without a light or LED. This is no big deal at all.
Since I have used Tenergy batteries with great success I feel confident that after just a couple months using these, I see no reason to believe that they are any less in quality and much more in performance.
Hope this helps!
