The Ambient Weather BC-1900 is the most advanced 9V battery charger on the market.
The BC-1900 supports NiCd, Li-ion (protected only) and NiMh 9V batteries.
Important Note: For LiIon batteries, only use protected batteries. Protected Li-Ion batteries will automatically stop charging.
Built for Safety: The BC-1900 intelligent battery charger is sophisticated, simple to use, smart, and safe. The charger features four independent channels that can be programmed as group or individually.
The BC-1900 can also revive spent rechargeable batteries, or recondition batteries that have not been used for a long period of time, restoring them to their rated original capacity. In addition, batteries can be tested for present capacity and end of life.
The BC-1900 charges and discharges NiCd, NiMH or LiIon (protected) rechargeable batteries. The BC-1900 provides four independent charging slots. In addition, the charger can also optimize and test the maximum capacity of each rechargeable battery.
The charger can also charge batteries of different sizes, types and capacities at the same time.
The charger integrates the voltage change over time, referred to as the "minus delta voltage", and automatically terminates charging.
When the battery is fully charged, the charger will automatically continue to provide a trickle charge. Trickle charging prevents the rechargeable batteries from being overcharged, and compensates for self-discharging of the batteries.
The charger features an easy to read black backlit display.
This package includes a UL rated AC adapter.
Comprehensive Operational Modes
Charge Mode: The rechargeable battery is charged up to its maximum capacity. The charging rate (current) can be independently adjusted for each battery.
Discharge Mode The discharge mode reduces the "memory effect". The rechargeable battery is discharged to a preset battery voltage. Once the discharge is finished, the battery will be charged at the pre-selected charging current.
Refresh Mode: A rechargeable battery is charged and discharged repeatedly to optimize to its maximum capacity. Old rechargeable batteries or rechargeable batteries that have not been used for a long period of time can be restored to their rated capacity. Depending on the selected charging current, it can take days before completed. The refresh mode will complete three discharge and charge cycles before completed.
Test Mode: The test mode checks the present capacity of the rechargeable battery. The maximum capacity is determined by discharging the rechargeable battery after fully charged. If the maximum capacity is much lower than the rated capacity then it may be near its end of life.
Quick Test Mode: The charger will analyze the dynamic internal battery resistance by applying a load current, and measuring the current.
Designed with Safety in Mind
Short circuit protection is designed on the main board. The charger will not be damaged, even when the battery is completely short circuited.
The rugged construction offers extensive ventilation for the batteries and charging circuits.
Advantages over Competitive Chargers
1. 16 bit Delta-Sigma Analog to Digital Converter resolution accurately determines the termination condition when charging batteries at different charging rates.
2. Larger footprint and additional space between batteries improves heat dissipation and improves charging times.
3. Includes Quick Test Mode
The car adapter (BC-2000-DC-ADAPTER) plugs into your vehicle's DC plug for applications on the go.
