ProMaster DB-120 Ricoh Lithium Ion 3.85V 1850mAh

ProMaster Rechargeable Lithium-Ion Battery (Ricoh GR IV Series Replacement)
Premium Replacement Power Pack – High-Capacity 1,850 mAh / 7.12 Wh Output at 3.85V, Fully Decoded Smart IC Chip for Accurate Power Level Display, Full Compatibility with In-Camera Charging & OEM Wall Chargers, Fire-Retardant Internal Circuitry with Multi-Stage Electronic Protection, Reusable Protective Travel Storage Case, Compatible with Ricoh GR IV, GR IV HDF, and GR IV Monochrome (Excellent Condition)

The ProMaster Rechargeable Lithium-Ion Battery is a premium-grade replacement power cell engineered specifically for the Ricoh GR IV series compact premium cameras (including the GR IV, GR IV HDF, and GR IV Monochrome). Engineered for street photographers, documentary creators, and travel enthusiasts who rely on pocket-sized form factors and long-lasting shooting endurance, this battery is built with high-grade lithium-ion cells to deliver reliable performance, extended charge-cycle longevity, and verified power delivery that matches factory specifications.

Unlike aftermarket options that utilize partially decoded chips or overstated capacity ratings, ProMaster power packs incorporate fully decoded microchips that communicate seamlessly with camera firmware. This ensures precise on-screen battery percentage readouts, zero compatibility warnings, and support for in-camera USB charging as well as external manufacturer charging docks. Internally, the battery features fire-retardant printed circuit boards (PCBs) paired with comprehensive electronic protection against overcharging, over-discharging, overcurrent, overvoltage (voltage regulation), and short circuits. It ships in a reusable hard-shell protective travel snap case that shields the terminal contacts from dust, physical impact, and accidental metal shorting during storage and transit.
