Questions about this item

What devices does the Kastar LI-42B 3-pack replace?

These batteries replace the Sony VGP-BMS77, 4-268-590-02, SP60 and SP60BPRA9C packs used in Sony Bluetooth Laser Mice.

Will the 1400 mAh cells work in place of the original lower-capacity pack?

Yes, the 3.7 V lithium-ion chemistry matches the original specification so the mouse will operate normally with longer run time per charge.

How can I confirm the pack is charging correctly after installation?

The built-in protection circuit prevents over-charge and over-discharge; the mouse charging indicator will show normal activity when the battery is functioning as intended.
