Mathorn MB-190 Ultimate 1270 mAh – Replacement Battery for Ricoh DB-110
The Mathorn MB-190 Ultimate is a replacement battery for the Ricoh DB-110, built for Ricoh GR users as well as photographers working with rugged WG and G series compacts. With a nominal capacity of 1270 mAh, it serves well both as a primary cell and as a pocket-sized spare for street photography, travel, and full-day assignments.
Reliable power for everyday shooting
The battery delivers a nominal capacity of 1270 mAh and 4.6 Wh of energy, providing steady voltage during high-resolution shooting and continuous burst mode. It is also a practical way to restore full runtime to cameras whose original factory batteries have lost capacity over time.
Backup power without extra bulk
Ricoh GR cameras are known for their compact size, which also limits the capacity of their internal battery. Heavy use of the LCD screen, autofocus, image stabilization, and photo review can quickly drain a single cell. Lightweight and small enough to fit into a coin pocket or minimalist pouch, the MB-190 Ultimate lets you swap batteries on the go and keep shooting without stopping to recharge.
Lithium-ion cell
The battery uses a selected lithium-ion (Li-ion) cell offering high energy density in a slim housing. Because Li-ion technology has no memory effect, you can top up the battery at any charge level without having to drain it first.
Compatibility
The battery works with dedicated chargers supporting the DB-110 standard (including the original Ricoh BJ-11 charger) and the following camera models:
- Ricoh GR series: GR III, GR III Street Edition, GR III Diary Edition, GR III HDF, GR IIIx, GR IIIx Urban Edition, GR IIIx HDF
- Ricoh WG series: WG-6, WG-7, WG-8
- Ricoh G series: G900, G900SE
