Two-pack BL-5B replacement batteries

The set includes two lithium-ion cells rated at 3.7 volts and 890 milliampere-hours each, delivering 4.26 watt-hours per battery. They are direct replacements for the BL-5B model used in numerous compact cameras and portable devices.

Foldable-plug LCD charger

The bundled AC charger accepts 100 to 240 volts at 50 to 60 hertz and outputs 4.2 volts at 600 milliamperes. A foldable flat pin makes storage compact, while red and green LEDs show charging and full-charge status.

Owners of listed Minox, Rollei and Vivitar models

Photographers using compatible Minox DCC 5.0, Rollei 10050 series or Vivitar compact cameras gain a spare power solution with clear charge indication. Buyers whose devices require a different battery form factor or voltage should look elsewhere.

Questions about this item

How many charge cycles can the 890mAh lithium-ion cells handle before they need replacing?

Lithium-ion cells in this class typically deliver several hundred full cycles before capacity drops noticeably; rotating the two included packs spreads the wear.

What limits the charger when both batteries are docked for long sessions?

The charger outputs 4.2V at 600mA, so each cell charges at that rate; sustained use is limited by this fixed current rather than heat or time.

How much heat or noise does the wall charger produce during all-day charging?

The compact AC adapter with foldable flat pins runs silently and stays only warm to the touch because it draws a low 600mA DC output.
