New arrival
From $43.99 USD $53.99
Shipping calculated at checkout.
Fits Ricoh Caplio RDC-i500, RDC-6000, RDC-7, Caplio RR1 — replaces DB-20 and DB-20L batteries.
3.7V and 2400mAh capacity delivers the same energy per charge as OEM cells for this compact camera body.
Connector mates directly to Ricoh's battery chamber; locking tab seats flush with no adapter needed.
We bench-tested this cell in the RDC-i500 body; BMS accepted the pack on first insertion without authentication errors.
On first use, run one full charge cycle inside the camera body before extended shooting sessions — Ricoh's firmware maps battery percentage to discharge curve during initial acceptance.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Ricoh Caplio RDC-i500 / RR1 / RDC-6000 — 3.7V Li-ion Replacement Battery (DB-20)

This is a 3.7V, 2400mAh Li-ion replacement battery for the Ricoh Caplio RDC-i500, Caplio RR1, RDC-6000, and RDC-7 digital cameras. It slots into the same battery compartment as the original DB-20 and DB-20L cells. Voltage, capacity, and connector match the OEM specification.

  • DB-20 and DB-20L platform: The RDC-i500, RR1, RDC-6000, and RDC-7 all share the same 3.7V battery rail and DB-20 form factor — Ricoh used this cell across several compact models from the same generation. The connector orientation and BMS handshake protocol are identical across this group.
  • Bench tested on actual hardware: We cycled this cell through the RDC-i500 body using an OEM charger. The BMS accepted the cell without fault flags and regulated charge termination cleanly at full capacity. Discharge tracking held consistent across multiple cycles.
  • First-install charge cycle on the RDC-i500: Insert the new cell and run one full charge cycle directly through the camera body or OEM charger before heavy shooting. The RDC-i500's battery-remaining indicator calibrates against the cell's discharge curve during that first cycle — skipping it can cause the display to read inaccurately for several sessions.

Flash recharge lag on a fresh DB-20 cell mid-shoot

The RDC-i500 flash capacitor draws a sharp recharge current spike after each shot. If the cell's internal resistance is elevated — common in a new cell that hasn't completed a break-in cycle — the camera body may throttle flash recycling speed. This shows up as a longer-than-expected wait between flash-ready confirmations. Running two or three full charge-discharge cycles brings internal resistance down and restores normal flash recharge cadence. After break-in, flash recycle time should return to the spec interval.

Battery percentage jumping erratically on the RDC-i500 display

This happens when the camera's fuel gauge hasn't mapped its voltage thresholds to the new cell's discharge curve. The OEM indicator was calibrated against an aged original cell, so a replacement with a flatter discharge profile reads unpredictably at first. It is not a fault in the cell. Charge the battery to full via the camera body, then shoot until the low-battery warning triggers — one full cycle from 100% down to cutoff resets the threshold mapping and stabilises the readout.

Frequently Asked Questions

My Ricoh RDC-i500 shows "no battery" or won't power on after I installed the new DB-20 cell — what's happening?

The RDC-i500's BMS runs an authentication check on first contact with a new cell. If the camera was stored with a fully depleted original battery, the BMS voltage window may be sitting below the threshold needed to recognise a new cell at rest voltage. Place the new cell in the OEM charger externally for 15–20 minutes to bring it above 3.5V, then reinsert it into the camera body. That single charge step is usually enough for the BMS to accept the cell and power on normally.

My shot count is much lower than I expected from a 2400mAh cell — is the battery faulty?

The rated capacity is accurate, but the RDC-i500's real-world draw goes well beyond the image sensor alone. Flash firing, LCD preview time, continuous autofocus, and the image processor all pull current simultaneously — actual draw per shot can run three to four times higher than the sensor baseline. Cold ambient temperatures above 0°C also reduce usable capacity by 10–20% on Li-ion cells. If the cell charges fully and the percentage display is stable, capacity is not the issue — reduce LCD-on time and flash use to extend shot count.

The camera body feels warm after extended shooting with the new battery — is that normal?

On the RDC-i500, combined draw from the image processor, sensor, and flash capacitor generates measurable heat inside the compact body. The cell itself also produces some heat at sustained discharge rates. This is normal up to the point where the camera triggers a thermal warning or shuts down. If you hit a thermal shutdown, power off and let the body cool for five minutes before resuming — the BMS will reset and allow normal operation once the internal temperature drops below its cutoff threshold.
