Product Description
We highly recommend these batteries for wireless microphones, TENS units, guitar effect pedals, wireless guitar and bass systems, in-ear monitors and other devices that call for a 9-volt sized battery.
Warning!
Given the technology behind these batteries, a standard NiMH/NiCd charger will NOT charge this battery. You need a charger designed for Li-Poly/Li-Ion batteries. The charger we offer that will charge this battery is our 2 Bank 9 Volt Battery Charger.
Charging this in a charger not designed for Li-Poly batteries will cause fire or explosion. Charging this battery in a NiMH/NiCd charger will void your warranty.
Important note about the voltage of this battery:
Rechargeable batteries, like this 9V-size Lithium Ion battery, are rated at a lower voltage than their Alkaline-based alternatives. If your application absolutely requires a full 9 volts to operate, rechargeable batteries may not work for you. Please view the datasheet or give us a call at 1-800-405-2121 for further information.
If your device has a charge indicator, this battery will most likely not show a "full" charge when installed. These indicators are calibrated for alkaline 9 volt batteries, which, by design, have a higher initial voltage level than a fully charged rechargeable battery. The battery will work, but the indicator will display inaccurate results.
Customer Reviews
Besides the shipping being super slow, no other battery can compete with this one. The Li-Ion Polymer battery fully charges in 1 hour and lasts far longer than any other 9V battery available today. Highly recommend!
Received my batteries in new condition. So far, the batteries are performing well, with at least as much, if not more, capacity as a standard 9 volt battery. The true test is how long they will last. Time will tell.
I’ve been using these batteries for years in guitar and ear monitor wireless systems. Never have a problem with them at all. I’ve charged them over and over hundreds of times and Have not lost their charge time. The only downfall I would say is that when they go dead, they go dead. There’s no warning. But I have adjusted with that. Saves me hundreds of dollars buying batteries.
Charge quickly and hold a charge like no-other
Item as described. A little pricy but you get what you pay for
I was hesitant to purchase due to the price to begin with, but I use medical TENS units for pain control and was constantly having the batteries run out of power at the most inconvenient times. In fact, I had to change batteries at least 4 times per day on each unit! I can hardly believe it myself, but I am able to use these batteries constantly for two whole days without having to change! That is PHENOMENAL!!!!!!! Thanks for a GREAT product!
Bought 3 batteries and used one to test. Left one in wireless mike and several days later it would not turn on. Put battery in charger and it will not charge. Have not used other 2 yet. My NiHi cell is more reliable which I have more than 7 years and still going..
