The D4 Digicharger Battery Charger from Nitecore is compatible with almost every type and size of cylindrical rechargeable battery and is equipped with individual bays to simultaneously charge four batteries, even ones of different size and capacity. It automatically detects the chemistry of each battery installed and determines the specific needs and requirements of each to optimize charging. When using smaller low-capacity batteries, such as AA or 10440, or LiFePO4-type batteries the charger can be manually set to ensure proper charging without overheating or overcharging. An intuitive LCD screen provides real-time feedback on the batteries including: charging status, available battery power, remaining charging time, and charging mode. To protect the batteries, specialized circuitry helps to prevent over-heating and over-charging, and if a battery is installed incorrectly an error message is displayed and the charging current is cut to that specific bay.
Four independent charging bays
Separate spring-loaded sliders accept different battery sizes and ensures a secure connection
Engineered to efficiently charge Ni-MH and Ni-Cd battery chemistries
Low-capacity mode: Use when charging smaller batteries to prevent overheating and over-charging due to high charging current
LiFePO4 mode: Activate when using this battery chemistry to optimize charging and extend battery life
Over-charge protection cut current to prevent damage to batteries
Charger detects if a battery is installed backwards
An error message is displayed showing a problem
Current is cut to that bay to prevent damage to the battery
Detects battery number and current status of each
Automatically selects "constant current" or "constant voltage" depending on each battery requirement
Automatically determines appropriate termination voltage to help prevent over-charging
Switches to "trickle charge" when batteries are full to maintain full charges
Back lit for easy visibility, especially in the dark
Can be disabled for overnight charging without disturbing user
Displays and "Err" message when batteries are installed backwards
