Kastar BL-5B battery and charger kit

This pack supplies one 3.7 V lithium-ion cell rated at 890 mAh and a matching wall charger. It targets owners of compatible compact cameras, mini keyboards, FM radios and Bluetooth devices that use the BL-5B form factor. The bundle replaces an original pack and adds a dedicated charging cradle.

Foldable-plug charger with LED status

The included AC adapter accepts 100–240 V input and delivers 4.2 V at 600 mA through a foldable flat pin for compact storage. A red LED shows active charging while a green LED signals standby or full charge, removing guesswork from the recharge cycle.

Verify BL-5B compatibility before ordering

Check that your device lists the BL-5B model or one of the exact model numbers shown in the compatibility list. The charger output is fixed at 4.2 V 600 mA so it cannot charge larger-capacity packs or different chemistries. Buyers needing multi-bay charging or faster rates should look elsewhere.

Questions about this item

How many charge cycles can the 890mAh BL-5B handle before it needs replacing?

The lithium-ion chemistry provides reliable performance over hundreds of cycles; actual lifespan depends on usage patterns and storage conditions.

What limits the charger during continuous daily use?

The 600mA output current sets the charge speed; the unit draws 100–240V AC and delivers 4.2V DC without active cooling.

Does the charger get hot or make noise when left plugged in all day?

The compact wall adapter runs silently with no fan; it may become warm during charging but stays within normal operating temperature.
