How to buy rechargeable batteries

Rechargeable batteries are a great solution to power your Wildlife Acoustics recorders as they save a great deal of waste. However, if you get the wrong ones they will not work well. Most rechargeable batteries are designed for toys or other equipment where longevity is not critical. Also, many lower-end batteries will have a high self-discharge rate which means they lose power quickly, even when they are just sitting on the shelf.

Provided that you get the best batteries available, they will still not work well if you don’t recharge them correctly. There is a wide variety of chargers on the market. Low-end chargers will not “fill” batteries to their capacity and will not refresh them as is periodically required.

So what should you do?

We recommend that our customers make sure to purchase high quality batteries from a reputable source that have a low self-discharge rate and high output. We recommend and sell the IMEDION line which are the best we have come across. Be sure to get a good charger and follow the directions included. As far as chargers go, we recommend and sell the MaHa MH-C808M which can charge 8 batteries at a time and has modes for soft charging and reconditioning batteries.

Customer Spotlight: Echo Meter Touch bicycle transects

Can the Echo Meter Touch be used for bicycle transects?

For our resourceful customer Peder Halverson, the answer is yes.

Wondering know how he did it? Peder shared the details with us:

"It’s simply a camera monopod fastened to the bike’s front wheel frame, a wooden platform fastened to that, a cardboard iPad mini case box glued to that, the iPad mini in the carboard secured by a Velcro band. The module’s microphone is covered by a windscreen salvaged from a Zoom H2 recorder that was once used to record bat calls from a Petterson unit. The monopod pole can telescope up farther, but I like it this way for better visibility of the road ahead. The iPad can rotate on the monopod either this way, giving better visibility ahead, or it can rotate so that the screen is always visible to the rider. It likes to ride this way, slowly rotating to this orientation.

This method is being compared with the method in which the iPad is slipped into the rope pocket on the back of a backpack. So far the two methods seem to give equally good spectrograms, even though one might imagine the pole method to give less audio reflections. The backpack method allows the iPad’s cover to remain open, so that the screen is visible to automobiles to the rear, acting as a great additional reflector. It also feels a lot more secure for the iPad and module.
