"Ansmann is a game charger for me."

"Now I've done over 30 years - at lot of tours -- and have spent stupid amounts of money on batteries and I've thrown away and wasted so many batteries. The Ansmann stuff is beyond a game changer for me -- it's consistency with no waste and reliability at the same time. This is all I use from now on."

Daniel "Borga" O'Neil,

"We were throwing away $400 each year in disposable batteries."

“We were throwing away about $400 each year at our church, not to mention their effect on landfills. Now we have several chargers in key locations for our high use devices and we know they’ll work every single day.”

Travis Lee Moser, Technical Director
Morning Star Fellowship

We thank you very, very much Ansmann Rechargeables!

“I use Ansmann batteries for Wireless Microphone and In-Ear systems for all the Cirque du Soleil shows I work on. They work very well for us and are very reliable. We are doing 10 shows a week.”

Jean-Michele Caron, Project Manager
Cirque du Soleil

We were expecting good performance - but not this good !

“We’ve just completed a grueling 6 day shoot – filming between 15 and 18 hours per day. We were running 9 Sennheiser evolution wireless mike systems all day — and we never had to change batteries.”

David Springbett, Director
Asterisk Productions

Brand: Ansmann

First, choose the correct rechargeable battery for your application.

1. What are your run-time requirements - 2 hours? 8 hours? Choose a battery that exceeds your average run-time by at least 25%

2. Is your device dimension sensitive? Some models and brands (particularly Shure UHR models) require a slimline battery. Both the Ansmann 2850 slimline and the Fujitsu 2000 are slim enough for dimension-sensitive models

3. What about voltage and battery capacity? All three types of AA batteries have sufficient voltage and capacity to run high-drain devices such as wireless mics and IEM's. Although the "nominal" voltage is listed at 1.2V, these pro-grade rechargeables start with a minimum of 1.4V and maintain voltage levels for the length of their runtime. (as opposed to alkaline batteries that gradually lose their voltage levels)

Next, choose the battery charger(s) to accomodate how many wireless units you need to power.

1. All battery chargers listed below are designed for high demand, pro-grade rechargeables.

2. All chargers are equipped with advanced battery diagnostics and maintenance.

3. All chargers automatically top-off the battery and switch to trickle charge for 100% readiness.

4. Batteries should be left on the charger until ready for use. After use, return the battery to the charger. It does not have to be drained down, as there is no memory effect with these batteries. Draining the battery completely down will diminish the life expectancy.
