Compatible Olympus cameras

The Kastar pack supplies four lithium-ion batteries and a triple-bay charger for Olympus Stylus and OM SYSTEM Tough models including the TG-6 and TG-7. Each cell delivers 3.7V and 1300mAh for 4.81Wh of capacity. The kit replaces Olympus LI-90B, LI-92B, LI-90C and UC-90 power accessories. Photographers who need a single proprietary format for multiple Olympus bodies will find this set convenient.

Charging thermals and noise

The charger draws 5V 2A from any USB source and outputs 4.2V at 0.5A per bay, so three batteries charge simultaneously without fan noise. An integrated LCD shows real-time status and remaining capacity for each slot. The solid-state design produces no audible sound and runs cool during normal replenishment cycles. Users who require silent operation in quiet environments will appreciate the passive layout.

Sustained multi-bay charging

Under continuous use the charger maintains 0.5A per channel across all three bays until each cell reaches full voltage. The LCD continues to report individual progress without throttling or thermal shutdown. Four batteries rotate through the three slots to keep a camera powered during long shooting sessions. Shooters who demand more than three concurrent full charges must wait for a bay to free.

Questions about this item

How do I install the Kastar LI-90B batteries and triple charger for my Olympus TG-6?

Insert each 1300 mAh 3.7 V battery into the charger slots, connect the Micro USB cable to a 5 V 2 A USB wall or auto charger, and the LCD will show status for up to three batteries charging at once.

What maintenance will the LI-90B batteries need over time?

The 4.81 Wh lithium-ion cells gradually lose capacity; replace them when run-time drops below your needs, and keep contacts clean for reliable charging at 4.2 V 0.5 A per slot.

What is the first limit I will hit during extended shooting with these batteries?

Each battery holds 1300 mAh at 3.7 V, so continuous high-drain use will exhaust the 4.81 Wh capacity before the charger can replenish the three-slot 0.5 A output rate.
