Questions about this item

What does the Kastar BL-5B 2-pack include and is any extra cable needed?

The pack contains one smart LCD charger with a foldable flat AC plug and two 3.7 V 890 mAh lithium-ion batteries. No separate cable is required because the charger plugs directly into a wall socket.

Should I choose this 890 mAh version or a higher-capacity BL-5B if one exists?

This model supplies 890 mAh (4.26 Wh) per cell, matching the original Nokia BL-5B specification. If your device manual lists 890 mAh, this is the correct capacity; a higher figure would indicate a different battery series.

What does the 600 mA charger output mean for actual recharge time?

The charger delivers 4.2 V at 600 mA, so each 890 mAh battery takes roughly one and a half hours to reach full charge from empty. The LED shows red while charging and green when complete.
