What the kit includes

The kit supplies two 3.7V 740mAh lithium-ion batteries and a dual-slot charger with a micro-USB cable. It replaces Olympus Li-40B and Li-42B cells and also fits Fujifilm NP-45S packs. Photographers carrying a compatible Olympus Stylus or Tough model gain a spare set without hunting for proprietary chargers.

Charging limited to micro-USB 5V 2.1A input

The charger only accepts power through a micro-USB port rated at 5V 2.1A, so it cannot be powered from USB-C or lightning sources without an adapter. Each slot delivers 4.2V at 730mA, meaning a full charge takes longer than dedicated AC docks. Users relying on high-wattage USB-PD bricks will see no speed benefit.

Compact charger with LED status per slot

The dual charger fits in a small bag and shows green when idle, red while charging, and green again when each cell finishes. Micro-USB cables are still common in cars and power banks, so topping up on the road is straightforward. The package omits a wall adapter, so buyers without spare USB chargers must provide their own.

Questions about this item

Should I buy the 2-pack or a single battery for my Olympus Stylus 1040?

The kit includes two 740mAh batteries and a dual charger, so you always have a spare ready while the other is in the camera or charging.

What does the 740mAh rating mean when I am out shooting?

Each cell delivers 3.7V at 740mAh, roughly tripling the runtime you would get from a single original battery during a day of travel photography.

How does the micro-USB 5V 2.1A input limit charging speed?

The charger draws up to 2.1A from any USB wall adapter, car charger or power bank and feeds each battery at 730mA, so both cells charge simultaneously at that rate.
