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.

Kyocera DuraForce Pro E6810 / E6820 / E6830 — 3.8V Li-ion Replacement Battery (SCP-67LBPS)

This is a 3.8V, 3100mAh (11.78Wh) Li-ion cell built to replace the OEM SCP-67LBPS battery in the Kyocera DuraForce Pro series. It fits the E6810, E6820, and E6830 variants. The connector and cell dimensions match the original bay — 96.50 × 53.10 × 5.05mm.

  • E6810 / E6820 / E6830 compatibility: All three DuraForce Pro variants run the same 3.8V power rail and use the same BMS handshake protocol. One battery part number — SCP-67LBPS — covers all of them because Kyocera kept the connector, BMS interface, and cell format identical across the E68xx family.
  • Bench tested on actual hardware: We cycled this cell through full charge and load discharge on the DuraForce Pro platform. The BMS accepted the new cell without error flags, and the charge IC stepped through trickle, constant-current, and constant-voltage phases as expected.
  • Fuel gauge recalibration on first use: On first installation, disable fast charging and run one full discharge-charge cycle at standard rate. The DuraForce Pro's fuel gauge IC maps its coulomb counter to the discharge curve of the installed cell — doing this before enabling fast charging prevents the gauge from feeding current into an uncalibrated profile.

Sudden shutdown at 20–30% on the DuraForce Pro after a cell swap

This is a voltage cliff problem, not a capacity problem. When the modem fires at full power — during a call, data burst, or GPS fix — it pulls a sharp current spike. If the fuel gauge IC hasn't completed a calibration cycle against the new cell's discharge curve, it can misread the state of charge by 15–25%. The cell voltage drops below the BMS cutoff threshold under that load spike before the gauge shows anything near zero. Run one full discharge to auto-off, then charge uninterrupted to 100%, and the fuel gauge resets its reference points against the actual cell.

USB-PD fast charge not activating after replacement

On the first charge cycle after installing a new cell, the DuraForce Pro's charge IC may default to standard 5V charging rather than negotiating USB-PD. This happens because the BMS presents a higher internal impedance on a fresh, unconditioned cell — the charge IC reads this and falls back to a safe baseline protocol. Disconnect the cable, power the phone off completely, then reconnect to the charger. After the first full standard-rate cycle completes, cell impedance drops and USB-PD negotiation re-engages normally on subsequent charges.

Frequently Asked Questions

My DuraForce Pro won't turn on after sitting in a drawer for a few months — is the new battery dead already?

It isn't dead — it's locked out. Li-ion cells that drop below roughly 2.5V trigger a BMS protection cutoff that blocks power delivery entirely. Connect the phone to a wall charger (not a laptop USB port) and leave it for 20–30 minutes without pressing the power button. The charge IC needs to push trickle current into the cell long enough to lift it above the BMS re-enable threshold, which sits around 2.9V on this platform, before the phone will respond.

The battery percentage is jumping around erratically — showing 60%, then jumping to 45%, then back up — what's causing that?

The fuel gauge IC inside the DuraForce Pro is running a coulomb counter calibrated to the old cell's discharge curve. When you install a new cell, those reference points no longer match the actual voltage-to-capacity relationship of the replacement. The gauge compensates by jumping as it encounters voltage readings that don't fit its stored model. One complete discharge cycle — from 100% down to auto-shutdown — followed by a full uninterrupted charge resets the coulomb counter baseline and the erratic readings stop.

The phone feels warm near the back panel while charging the new battery — should I be concerned?

Mild warmth on the first few charges is normal. A fresh cell has higher internal impedance than a conditioned one, and the charge IC dissipates more energy as heat while pushing current into a higher-resistance cell. As long as the phone is not hot to the touch and charging hasn't stopped, this is expected behaviour. After two or three full cycles the cell impedance drops and the warmth during charging reduces noticeably — if it stays hot after cycle three, check that you're not charging on a surface that traps heat, like a couch or pillow.
