What is the Pure Power Series? Defining the 1.5V Standard
The Pure Power Series represents a fundamental shift in how professional facilities manage mobile energy. Unlike consumer-grade rechargeables, this is a professional 1.5V Lithium-ion rechargeable AA battery system designed for environments where failure is not an option. While some manufacturers use similar branding for uninterruptible power supplies or PC components, this series focuses specifically on the high-stakes requirements of wireless microphones, medical equipment, and high-drain production tools. Horizon Battery has served as the specialized distributor for these professional solutions since 1998, providing the technical expertise required to transition large-scale operations away from disposable cells.
The Evolution of Professional Mobile Energy
For decades, alkaline batteries were the industry standard because they provided a nominal 1.5V output. This specific voltage is critical for the internal circuitry of professional wireless transmitters and sensitive medical devices. When Nickel-Metal Hydride (NiMH) rechargeables arrived, they offered a sustainable alternative but carried a significant flaw: a lower nominal voltage of 1.2V. This discrepancy often leads to inconsistent signal range or premature low battery warnings on expensive gear. The Pure Power Series bridges this gap by utilizing an advanced Lithium-ion battery core coupled with internal regulation. This combination delivers the constant 1.5V performance of an alkaline with the long-term cost benefits of a rechargeable cell.
Key Technical Specifications of the Series
The engineering behind these cells centers on a sophisticated Battery Management System (BMS). This internal circuit steps down the native lithium voltage to a regulated 1.5V, maintaining that level until the cell is exhausted. This ensures your equipment receives full power throughout the entire discharge cycle. Performance is defined by several key metrics:
- Capacity: The Type 3500 model offers a nominal capacity of 3500 mAh, providing the high-capacity energy density needed for long performances or clinical shifts.
- Cycle Life: These cells are rated for up to 1,500 recharge cycles, which dramatically reduces the volume of hazardous waste generated by a facility.
- Safety: Integrated protection against overcharging and short circuits is standard; the cells are certified to IEC 62133-2:2017 standards.
- Temperature Stability: Reliable operation is maintained across a wide range, from -20°C to +60°C.
To maintain these performance levels, the system requires a dedicated charging module or a compatible charging cradle. Standard chargers can damage the internal regulation circuitry. This is why the series is managed as an integrated ecosystem of cells and specialized hardware, ensuring longevity and safety for the entire battery inventory.
Constant Voltage vs. Voltage Sag: The Pure Power Advantage
Voltage sag is the hidden enemy of professional wireless audio. As standard batteries discharge, their voltage output gradually declines. This phenomenon directly impacts the performance of wireless microphone transmitters and in-ear monitor packs. When voltage drops, the RF signal strength can weaken, leading to reduced range, increased noise floor, or audible distortion. While many consumer reviews focus on raw capacity, expert recommendations for rechargeable batteries in professional settings increasingly emphasize voltage stability over simple milliamp-hour (mAh) ratings.
The Pure Power Series addresses this by maintaining a flat discharge curve. Unlike an alkaline battery that starts at 1.5V and immediately begins to slide toward 0.9V, these cells provide a steady 1.5V from the moment the gear is turned on until the cell is fully exhausted. This consistency is vital for maintaining the integrity of digital wireless systems that require a specific voltage threshold to operate their internal processors reliably.
Lithium-ion vs. NiMH vs. Alkaline Comparison
Professional gear is usually calibrated for the 1.5V standard of alkaline batteries. Standard 1.2V NiMH batteries often cause equipment to display a "low battery" warning even when the cell still holds significant energy. This happens because the device interprets the 1.2V starting point as a near-depleted alkaline cell. High capacity in a NiMH cell doesn't translate to longer runtime if the device shuts down prematurely due to this voltage mismatch.
| Battery Type | Start Voltage | Mid-Cycle Voltage | End-Cycle Voltage |
|---|---|---|---|
| Pure Power (Li-ion) | 1.5V | 1.5V | 1.5V (Constant) |
| Alkaline | 1.5V | 1.2V | 0.9V |
| NiMH | 1.2V | 1.2V | 1.0V |
The integrated buck converter acts as a precision regulator, stepping down the native lithium cell voltage to a consistent 1.5V output. This ensures that the energy stored in the cell is actually accessible to 1.5V-sensitive equipment throughout the entire cycle.
Protecting Sensitive Professional Circuitry
Hardware "brownouts" occur when voltage dips low enough to cause digital circuits to malfunction or reset. In a live production or a critical healthcare environment, a momentary reset of a transmitter can result in several seconds of silence or data loss. For more technical details on deployment, consult our Pure Power Series: The Professional Guide to Lithium-Ion AA Batteries.
Maintaining stable power is equally critical for medical telemetry and patient monitoring. Inconsistent voltage leads to unreliable data transmission, which can complicate patient care in large facilities.

Addressing Professional Concerns: Safety and Interference
Skepticism often surrounds the use of regulated lithium cells in sensitive audio environments. It's a common concern among audio engineers that the internal electronics required to step down voltage might introduce electronic hum or RF interference. However, the Pure Power Series is engineered specifically to address these professional requirements. By utilizing advanced internal shielding and high-frequency regulation, these cells maintain a clean noise floor that meets the rigorous standards of modern broadcast and live sound.
RF Cleanliness and Audio Standards
To ensure RF cleanliness, the internal switching regulator in each cell operates at a frequency far beyond the audible range and the UHF/VHF bands used by wireless systems. This prevents the "switching noise" that can plague lower-quality consumer cells. Professional testing shows that the noise floor of the Pure Power Series is indistinguishable from traditional alkaline batteries. This makes them a reliable choice for high-sensitivity condenser microphones and digital transmitters where signal integrity is paramount. They don't suffer from the same signal degradation issues that appear when standard rechargeables begin to lose their charge.
Thermal management is another area where these lithium cells outperform traditional NiMH alternatives. NiMH batteries generate significant heat during high-drain use because of their higher internal resistance. In contrast, the lithium chemistry in this series remains remarkably cool even under heavy loads. This protects the delicate internal components of your gear and ensures the battery chemistry remains stable in fluctuating environments, from cold outdoor stages to hot broadcast studios.
Safety Certifications and Logistics
Reliability extends to the physical safety and transportability of the cells. Every battery in the series is certified in accordance with UN Transport Regulation 38.3. This certification is essential for touring professionals who must transport equipment via air freight. Additionally, the integrated Battery Management System (BMS) includes protection circuits that prevent damage from deep discharge or short circuits.

These cells are also certified to IEC 62133-2:2017 standards, ensuring they meet global safety requirements for portable electronics. This level of certification provides peace of mind for facility managers who are standardizing their battery inventory across multiple departments. By choosing a product with documented safety standards, you eliminate the risks associated with uncertified "white label" lithium cells that lack proper internal regulation. This structured approach to safety ensures that your power source is as professional as the equipment it drives.
ROI Analysis: The Economics of Enterprise Battery Transitions
Analyzing the total cost of ownership reveals that the largest expense in battery management isn't the unit price, but the recurring cost of replacements and the labor required to manage them. For an enterprise facility, the cycle of purchasing, storing, and disposing of thousands of alkaline cells creates a significant financial drain. The Pure Power Series addresses this by providing a high-capacity cell rated for up to 1,500 recharge cycles. This longevity transforms batteries from a consumable expense into a long-term capital asset, effectively eliminating the need for monthly procurement cycles and reducing the volume of hazardous waste sent to landfills annually.
Beyond the purchase price, "labor leakage" represents a hidden cost that many facility managers overlook. Staff hours spent testing partially used alkalines, sorting dead cells, and performing emergency battery swaps during events add up quickly. By standardizing on a reliable rechargeable system, organizations can streamline their workflows and redirect personnel to more critical technical tasks. The environmental impact is equally substantial, as a single set of rechargeable cells can replace thousands of disposable batteries over its operational life.
Case Study: Church and School AV Systems
A typical house of worship or educational facility operating a 20-microphone setup can go through hundreds of batteries in a single semester. Switching to the Pure Power Series allows these organizations to recoup their initial investment within the first year of operation by removing the need for bulk alkaline purchases.
