Replacement Battery and Charger for Sony VGP-BMS77

Questions about this item

Does the PS-42B pack include both the battery and the AC wall charger, or do I need to buy the charger separately?

The pack contains one 1400 mAh 3.7 V lithium-ion battery and one AC wall charger with a foldable flat plug, so nothing else is required.

Which capacity should I choose for the Sony VGP-BMS77 mouse — is the 5.18 Wh / 1400 mAh version the only option?

This listing supplies the single 5.18 Wh (1400 mAh) battery that matches the original Sony 4-268-590-02, SP60 and SP60BPRA9C part numbers.

What does the 600 mA charger output mean for actual charge time in the mouse?

The charger delivers 4.2 V at 600 mA, so a full charge of the 1400 mAh cell takes roughly two to three hours; the LED shows red while charging and green when complete.
