| Lithium Ion would be preferable to the others because they can be recharged at any time .... no 'memory' problems. In fact, some cell phone companies recommend topping up the charge as frequently as possible for optimum battery life. |

| Horizon Solutions in London featured a great battery for wireless this past conference. They are in London Ontario. We use them at York University and quite like them. |

| Brian, I think that's a bit of mis-information. NiMh batteries don't suffer from memory problems either. In fact, at least one manufacturer recommends you leave them on the charger to keep them topped up on their high-capacity batteries. Lithium-Ion batteries by contrast may have higher capacities, but Lithium-Ion batteries actually last longer if you max their charge out at 80% of capacity or so. That's why the smart chargers (which you must use for lithium ion or risk overcharging and a fire) do a fast charge up to about 80%, then slow charge the remaining 20%. They put out way more waste heat charging in the last portion of the charge cycle. The latest generation of nimh batteries includes low-self-discharge characteristics, which are good for things like auto sensing flush toilets and taps, clocks, remote controls, etc, that don't draw lots of power. We've been using nimh batteries here for our wireless mics and headsets for a number of years with great success. The added bonus to using nimh over Li-ion is that they are cheaper, and easier to find. There is a great article here that compares runtimes of a bunch of different batteries, and explains a little more about the practical aspects of implementing rechargables in your sound rigs. http://churchtecharts.org/home/2011/3/14/rechargeable-batteries-the-1-year-test.html Hope this helps all! -Paul Brian Wainwright wrote: >Lithium Ion would be preferable to the others because they can be recharged at any time .... no 'memory' problems.

| Hi Paul, What do you use for chargers? Have you tried many different models? Thanks, Bruce |
