Three Stage Charging Methodology

In general, the PowerCharger will deliver a three stage charge routine to each battery.

1.Stage One will deliver a high rate charge matched to the capabilities of the battery (typically a one or two hour rate, depending on battery type and charger power module rating). During this stage, six separate cutoff methods are in operation, simultaneously, ensuring the fastest, safest charge for that battery. Stage One is indicated by the LCD displaying “Charging (Primary)”.:

TCO - Temperature cutoff which stops the Stage one charge precisely when a temperature indicative of full charge is reached;

Dt/dT - a microprocessor based algorithm which measures a rise in temperature over a specific time, very accurately indicating full charge. This method is also the recommended method for charging Ni-MH technology;

-∆V- a method to determine the end of stage one charging by identifying a characteristic “reverse slope” of a Ni-Cd cell. Since this characteristic can be disguised by the age, temperature and the number of the cells in a battery, it can never be employed alone;

CCO - this method requires the identification of the particular battery size (capacity) and chemistry, an exclusive Anton/Bauer Logic Series feature. The charger determines the maximum charge time for the particular battery and uses this information to ensure that overcharge conditions are avoided.

FUL - this determination is made when a fully charged DIGITAL battery is returned to a PowerCharger within specified parameters of time, temperature, and battery voltage. The DIGITAL battery communicates its fully charged condition and the charger confirms the parameters and immediately indicates a fully charged condition, without additional verification.

TEMPERATURE COMPENSATED VCO – for HyTRON series of batteries. Similar to a VCO, however, only operates within certain temperature parameters.

2.Stage Two charging is a BALANCING or “equalize” mode which calculates each battery pack type to offset any imbalance of the battery’s cells, created by unequal self discharge or any capacity mismatch of the individual cells in the pack. This stage can vary in duration from zero to as much as 16 hours, depending on the condition of the battery. A battery will typically leave Stage Two in 2-4 hours under average operating conditions. Stage Two is indicated by the LCD displaying “Ready (Secondary)”.

3.Stage Three charging is the Anton/Bauer exclusive Lifesaver maintenance mode. This patented pulse routine keeps batteries fully charged, free from self- discharge - indefinitely - without damaging heat associated with so-called “trickle charge”. Stage Three is indicated by the LCD displaying “Ready (Lifesaver)”.

NOTE: Anton/Bauer strongly recommends that batteries are kept on the PowerCharger until ready for use. The Lifesaver mode will keep them 100% charged and ready for use.

DUAL 2702, QUAD 2702 specifications

Anton/Bauer is a leading name in battery technology, especially renowned for its line of professional camera batteries and chargers. Among its standout products are the QUAD 2702 and DUAL 2702 battery chargers, specifically designed for the demanding needs of the broadcast and film industries. Both models provide reliable charging solutions to keep your camera equipment powered throughout rigorous shooting schedules.

The Anton/Bauer QUAD 2702 is a sophisticated four-position charger that caters to multiple battery types, including Gold Mount and V-Mount batteries. One of its primary features is the ability to charge two batteries at a time, significantly enhancing workflow efficiency. The charger uses advanced smart charging technology that automatically detects the chemistry of the attached batteries, optimizing the charging process for maximum performance and longevity.

Built with durability in mind, the QUAD 2702 features a rugged casing that withstands the rigors of on-set use. Additionally, its integrated LED indicators display the charging status of each battery, allowing users to monitor multiple batteries at a glance.

The DUAL 2702, while similar in many ways to its quad counterpart, offers charging capabilities for two batteries simultaneously. This makes it an ideal choice for smaller production teams or operators who might not require the full capacity of the QUAD model. Like the QUAD 2702, it also features an advanced charging algorithm that maximizes battery life, ensuring that professional videographers get the most out of their investment.

Both chargers are designed with versatility in mind. They are compatible with a wide range of Anton/Bauer batteries, making them an essential tool for any filmmaker or photographer. The DUAL and QUAD 2702 units also come equipped with a power supply circuit that can handle a wide range of input voltages, allowing them to be used in various locations around the world without issue.

In summary, the Anton/Bauer QUAD 2702 and DUAL 2702 battery chargers represent the pinnacle of professional battery charging solutions. With their robust construction, advanced charging technologies, and user-friendly design, they are invaluable assets for any audio-visual production team. Whether you're shooting on location or in a studio, these chargers ensure your equipment remains powered, allowing you to focus on what matters most: capturing stunning visuals.
