Kit contents

The Kastar LI-42B kit includes two 3.7 V 1400 mAh lithium-ion batteries and an LCD triple USB charger. It is designed for users who need spare power for compatible Panasonic handsets and the Sony VGP-BMS77 Bluetooth laser mouse.

Upgrade path

This kit replaces single-bay chargers and original-equipment batteries that no longer hold a full charge. The jump is worth it when you want to charge three cells simultaneously from any 5 V 2 A USB source.

Capacity and headroom

Each cell stores 5.18 Wh, giving typical talk and standby time for the listed Panasonic models. The charger outputs 4.2 V at 0.5 A per bay, so a fully depleted pack takes several hours; it is not suited for rapid top-ups during continuous heavy use.

Questions about this item

Does the charger need a wall outlet or can it run from a laptop USB port?

It runs from any 5 V 2 A USB source — wall adapter, car charger or computer — and includes a Micro-USB cable.

Which way do the batteries slide into the three bays so the LCD shows a reading?

Align the gold contacts with the bay pins; the LCD lights only when polarity is correct.

When should the two 1400 mAh packs be swapped out?

Replace them when the LCD consistently shows reduced capacity after a full 4.2 V charge cycle.
