Four-Battery Kit for Olympus Tough Cameras

This pack supplies four 3.7 V lithium-ion cells rated at 1300 mAh each, together with a foldable-pin AC charger. It replaces Olympus LI-90B and LI-92B batteries and fits Stylus TG-1 through TG-5, TG-Tracker and OM SYSTEM TG-6 and TG-7 models.

Charger Handles Worldwide Mains Without a Bulky

The wall unit accepts 100 to 240 V at 50 or 60 Hz and delivers 4.2 V at 600 mA to each cell. A red LED shows charging and green shows standby or full charge, so you can see status at a glance during extended shooting sessions.

4.81 Wh Capacity Decides How Many Spare Shots You

Each battery stores 4.81 Wh, which determines the number of frames or video minutes available before swapping. If your workflow demands more energy per outing, this capacity may limit continuous use.
