Duracell Procell Review - Current Specials

Check out the stories of users who have posted a Duracell Procell review:

“Duracell Procell AAs are the most reliable battery that I can find when looking to power our ten wireless microphones every Sunday mornings. Having to continually power wireless microphones week after week can become quite pricey but between the long lasting capability of Duracell Procell batteries and the affordable prices at Medic Batteries it has helped us stay within our budget.”

“We purchase ProCell 9V batteries on an ongoing basis. We use these trustworthy batteries in our wireless microphones because we must have 100% up time.”

“These Duracell Procell batteries are fantastic! We use them in a worship setting, powering our Sennheiser wireless handheld and beltpack format microphones. We generally get anywhere from 4 to 8 hours of life from a pair of these batteries.”

“Duracell Procell 9 Volt Alkaline Battery 72/Case (PC1604) - As an Irrigation and Landscaping Supply Company, we started selling the Procell after several years of positive customer feedback and proven field application performance. We recommend it to our customers upon purchase of Irrigation controllers (residential, commercial and most specially institutional satellite based ones) as they have provided stable programming storage, very few data corruption cases, and less call-back for our contractor clients. This product has eliminated a substantial amount of unnecessary product support issues caused by unreliable memory back-up batteries, resulting in reduced product warranty cost both for us and the manufacturers of the products we sell. We've previously stocked Panasonic Commercial 9V Alkalines. It proved to be a disaster - our customer returns/exchange rate rose along the same type of products across different brands. It took us months for us and our product manufacturers to figure out it was battery related. And longer to assure our customers that it wasn't the units, but the batteries. The Energizer Commercial 9V Alkalines proved to be quite a very competent replacement. Very stable voltage rates, long-lasting, reliable performance but at a higher price tag. However, complaints on the Duracell Procell were non-existent if any, it's about equal quality-wise at a better price, so it seemed a logical choice.”

There it is, Duracell Procell review straight from the users who love them. We know that your personal Duracell Procell review will be just as positive, or we wouldn’t offer them.

Wireless Microphone Batteries - A Q&A with Adam Rothwell from CrossWalk Community Church

How do you know which wireless microphone batteries work best? We talked with Adam Rothwell, Technology Director at CrossWalk Community Church in Williamsburg, Virginia about his experiences with wireless microphone batteries.

Medic: Thanks for helping us out Adam! So what types of wireless microphone batteries does your church use, and how many mics do you have?

Adam: AAs and 9 volts. We have 13 mics available, mostly Shure microphones. 

Medic: Have you ever tried rechargeable wireless microphone batteries?

Adam: We tried them once before, but they couldn’t last the entire 6 hours that we needed them to last on Sundays for our church services. They were depleted towards the end, it was very inconvenient. We are very happy with alkaline wireless microphone batteries.

Medic: When do you replace your wireless microphone batteries?

Adam: We always make sure to have fresh alkaline wireless microphone batteries for the Pastor’s mic every Sunday. When the service is over we use those batteries for things throughout the week like choir practice.

Medic: Great! Thanks again for your time, Adam.

Adam: My pleasure.

Sizes matter. Rechargeable batteries for wireless mics are not always an easy fit as dimensions can vary. Learn more here: Rechargeable 9V Batteries for Wireless Microphones

Voltage requirements. Many 9V rechargeables produce only 7.2 volts. When selecting a rechargeable battery for wireless mics, Buyer Beware! Hint: A true 9.6 volt rechargeable battery is what you are after when you plan to use 9V rechargeable batteries for wireless mics.

Manufacturer warnings. Some microphone manufacturers frown upon using 9V rechargeable batteries for wireless mics; they’re more accepting of rechargeable AA batteries.

Disciplined approach. To make rechargeable batteries for wireless mics pan out for your house of worship, a highly disciplined system is needed. Maintaining the system requires a different mindset than you may be used to.

Performance issues. Some common problems identified by wireless mic users who have given rechargeables a try are: mics not powering, underpowered mics, and powered mics not transmitting.

Emergency power. If using rechargeables, you still need some alkalines handy for emergencies. A must! Shop 9V and AA alkaline batteries.

Apples to apples comparisons. When comparing pricing, make sure to compare the cost of rechargeable batteries for wireless mics to bulk alkalines available from a merchant such as , not to retail pricing. Include the cost of chargers, replacement costs, etc, in your calculations.

Battery tester. This is a must regardless of which batteries you are using. Invest in a high quality tester such as a ZTS Multi Battery Tester. You’ll be amazed at what this device will tell you. Take those batteries that are not up to the task out of the mix before failing at some critical time.

After considering the environmental ramifications and the expense of disposable alkaline batteries, some wireless microphone users are making a move towards rechargeables. We’d like to share a few tips about rechargeable 9 Volt batteries for wireless microphones to guide your decision making and help you choose the right batteries to power your wireless mic.


Many different rechargeable 9 Volt batteries for wireless microphones are available on the market today, but we find reviews are mixed. Many people are experimenting with rechargeables, but there is no consensus on the best rechargeable 9 Volt batteries for wireless microphones. Duracell Procell alkalines are widely favored as the non-rechargeable option.

A wrong sized battery may not properly slide into the battery cavity. There may be warranty concerns should the rechargeable battery damage the device. Poor performance may result from a poor fit. Hint: battery size differences are not easily detected by the human eye; they vary in fractions of a millimeter. Rechargeable batteries may also change slightly in size (get bigger) when fully charged. 

Some microphone manufacturers frown upon using rechargeable 9 Volt batteries for wireless microphones, though they’re more accepting of rechargeable AA batteries. 

Many consumer-grade 9 Volt rechargeables produce only 7.2 volts. 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.

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.
