Kastar LI-90B battery and charger kit

The pack contains three 3.7 V lithium-ion batteries rated at 1300 mAh each and a compact AC wall charger. It replaces Olympus Li-90B and Li-92B cells for Stylus TG and Tough cameras from the TG-1 through TG-7 series.

Capacity and daily headroom

Each cell stores 4.81 Wh, enough for several hours of typical shooting on a single charge. Three batteries let you rotate cells through a full day of travel or outdoor use without mains power. The 600 mA charger output means a depleted pack needs a few hours to reach the green-LED full state.

AC 100–240 V input with foldable pins

The charger accepts worldwide mains voltages at 50 or 60 Hz and folds its flat plug for slim packing. Red and green LEDs show charging status at a glance. Buyers needing in-camera USB charging or higher-capacity cells should look elsewhere.
