Four-battery pack with dual USB charger

This kit supplies four lithium-ion batteries rated at 1300 mAh and 3.7 V each, together with an LTD2 charger that can handle two cells at once. The charger accepts Micro-USB or USB-C input at 5 V and delivers 4.2 V at 800 mA per slot. An integrated LCD shows charge progress for both bays. Everything arrives new and ready for immediate use.

Suits owners of Olympus Stylus and Tough models

Photographers using Olympus Stylus SH, SP, TG, XZ or Tough TG-Tracker, TG-6 and TG-7 cameras can swap depleted cells for fresh ones without waiting. The four-pack covers a full day of shooting and the dual charger replenishes two batteries simultaneously. Users who need a single spare cell or a charger with AC input should look at other options.

1300 mAh capacity per cell

Each battery stores 4.81 Wh at 3.7 V, matching the original Li-90B and Li-92B specifications. This capacity determines how many frames or minutes of video you can capture between charges. If your workflow demands higher energy per battery, this pack will not meet that requirement.

Questions about this item

Does the LTD2 charger get hot or make noise when charging two 1300 mAh batteries all day?

The charger outputs 4.2 V at 800 mA per slot and draws up to 15 W from a 5 V 2-3 A USB source, so it stays cool and silent during extended use.

What USB power source do I need to run the LTD2 charger at full 15 W?

Any 5 V 2-3 A USB-A or USB-C adapter — such as a standard phone charger or power bank — will supply the required 15 W via the Micro-USB or Type-C input.

Will these 3.7 V 4.81 Wh batteries work in my older Olympus TG-4 without a firmware update?

Yes, they are direct replacements for the Olympus Li-90B and Li-92B cells used in the TG-4 and all other listed Stylus and Tough models.
