Lithium batteries (Li-ion) are generally not recommended for Audio-Technica systems requiring AA batteries, because a single AA lithium battery can have a voltage as high as 3.8V, which is more than double the recommended single battery voltage. Although NiMH batteries will work, they will not perform as well as 1.5V AA alkaline batteries, nor give the performance to the wireless device that alkaline batteries will provide. It should also be noted that NiMH batteries are approximately 1.2V when fully charged. Currently, the only type of AA rechargeable battery Audio-Technica recommends is nickel-metal hydride (NiMH) with a milliamp-hour (mAh) rating between 2000 mAh and 2700 mAh. Some rechargeable batteries may also be used, but be aware that not all rechargeable batteries are created equal. Using quality alkaline batteries will help your wireless system perform at its peak. However, it is recommended that you remove the AA batteries if the product will not be used for an extended period of time.ĪTW-T1001 UniPak® and ATW-T1002 Handheld Wireless Transmitters

In addition, they are widely available, hold their capacity well in storage, have a predictable discharge rate, and usually do not begin to leak for several years. Alkaline batteries are convenient, offer an excellent balance between cost and operating life, and are reliable. AA alkaline batteries typically measure around 1.5V when brand-new. Selecting the correct battery will help ensure reliable wireless performance and satisfactory battery life.Īlkaline batteries are the preferred battery type for Audio-Technica wireless systems that require AA batteries (excluding SpectraPulse® **). There are plenty of different batteries available, from traditional alkaline batteries to various types of rechargeables, but they don’t necessarily provide the same level of service.

To learn more about 9 Volt Batteries for Wireless Microphones, read Rechargeable Batteries for Wireless Mics for Houses of Worship.Question: What type of batteries should I use in my wireless system?Īnswer: All wireless microphone transmitters (and some receivers *) rely upon batteries for their power. Two other essential items to invest in: a high quality charger for rechargeable 9 Volt batteries for wireless microphones and a high-end battery tester, such as the ZTS battery load tester.When selecting rechargeable 9 volt batteries for wireless microphones, Buyer Beware! Hint: A true 9.6 volt rechargeable battery is what you are after when you plan to use rechargeable 9 Volt batteries for wireless microphones. Many consumer-grade 9 Volt rechargeables produce only 7.2 volts.Some microphone manufacturers frown upon using rechargeable 9 Volt batteries for wireless microphones, though they’re more accepting of rechargeable AA batteries.

Rechargeable batteries may also change slightly in size (get bigger) when fully charged. Hint: battery size differences are not easily detected by the human eye they vary in fractions of a millimeter.

Poor performance may result from a poor fit. There may be warranty concerns should the rechargeable battery damage the device.
