Kastar LI-90B 4-Pack Battery Kit

This kit supplies four lithium-ion batteries and a foldable AC wall charger for Ricoh cameras using the DB-110 cell. Each pack delivers 1300 mAh at 3.7 V, rated at 4.81 Wh. The charger accepts 100 to 240 V input and outputs 4.2 V at 600 mA. LED indicators show red while charging and green when full.

Best for multi-camera Ricoh shooters

Ideal for owners of Ricoh GR III, GR IIIx, WG-6, G900 or THETA series cameras who want spare cells and a single wall charger. Not suited for users of other brands or for cameras requiring a different battery form factor. Photographers needing higher capacity cells or USB-C charging should consider alternatives.

1300 mAh capacity per cell

The 1300 mAh rating determines how many shots or minutes of video each battery can sustain before recharge. Verify that your Ricoh model lists DB-110 compatibility to ensure correct fit and voltage.

Questions about this item

How do I install the Kastar LI-90B batteries and charger for my Ricoh GR III?

Insert each LI-90B battery into the camera's battery compartment following the polarity markings, then plug the charger's foldable flat pin into a 100-240V AC outlet and place batteries in the charging slots; the red LED shows charging, green shows full charge.

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

Keep the charger's foldable plug and contacts clean; store the 3.7V 1300mAh Li-Ion batteries at partial charge in a cool place when not used for long periods to preserve their 4.81 Wh capacity.

What limit appears first when using the charger continuously for multiple batteries?

The charger outputs 4.2V at 600mA, so each 1300mAh battery takes over two hours to charge; sequential charging of four packs means the total cycle time is the first practical limit.
