Rechargable L-ION Battery DB-120

Ricoh DB-120 Battery — The Backup Battery Every GR IV Traveler Should Carry

The gist: The official replacement lithium-ion battery for the Ricoh GR IV — 1800mAh, up to 250 shots per charge — and the only way to extend a full shooting day without swapping cameras or searching for a USB outlet.

• 1800mAh, up to 250 stills per charge: The GR IV’s built-in battery is rated the same — carrying a second DB-120 effectively doubles your shooting capacity without adding meaningfully to bag weight.
• OEM Ricoh battery, guaranteed fit: Made by Ricoh specifically for the GR IV; third-party cells can vary in voltage regulation and fit quality, which matters in a compact camera where tolerances are tight.
• Hot-swap without tools: The GR IV’s bottom-loading battery compartment lets you swap batteries in seconds — practical in the field when you’re between scenes and can’t afford downtime.
• Up to 4 hours playback: Reviewing and culling images on-device during travel transit — useful when you don’t have a laptop at hand — runs approximately 4 hours per charge.

B&H Photo confirms the DB-120 is the designated battery for the Ricoh GR IV, rated at 1800mAh and 6.9Wh — the original specification that Ricoh engineers the GR IV’s power management around.

Best for: Ricoh GR IV owners who shoot full-day trips or events and want a spare battery on hand when wall charging isn’t practical. Skip it if: You own a GR III or GR IIIx — those cameras use the DB-110 battery, not the DB-120. Runs ~$60 — check the current price before buying.
