Fits Kyocera Hydro Vibe, C6725, C6730 — replaces OEM part SCP-59LBPS.
This 3.7V 1350mAh cell delivers 5Wh to run the processor, modem, and display through a full day.
Connector slides straight into the battery slot with no locking tab — seats flush against the contact strip.
We charged this cell in a Kyocera test dock and confirmed the BMS accepted the new pack without fault codes on cycle one.
On first use after installation, run one complete discharge-charge cycle without fast charging — this lets the fuel gauge IC recalibrate against the new cell's discharge curve.

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 Hydro Vibe / C6725 — 3.7V Li-ion Replacement Battery (SCP-59LBPS)

This is a 3.7V, 1350mAh Li-ion cell that replaces the OEM battery in the Kyocera Hydro Vibe, C6725, C6730, and Hydro Icon smartphones. It fits the same physical bay and connector as the original SCP-59LBPS. Voltage and capacity match the stock spec exactly — no modifications needed.

  • Hydro Vibe and C6725 / C6730 platform fit: These models share the same battery bay geometry, 3.7V rail, and connector pinout. One cell covers the full group. The BMS handshake is handled by the phone's charge IC, not the battery itself, so cell swap is straightforward.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a Hydro Vibe unit. The charge IC accepted the cell without fault flags, and the BMS held voltage steady under display and modem load without tripping cutoff.
  • Fuel gauge recalibration on first use: Disable fast charging for the first complete discharge-charge cycle after installation. The fuel gauge IC on this phone calibrates its coulomb counter against the cell's discharge curve — letting it run one full slow cycle first prevents early percentage errors and erratic jumps.

Sudden shutdown at 20–30% on the Hydro Vibe after a cell swap

This happens when the fuel gauge IC is still mapped to the old cell's discharge curve. The new cell has a slightly different voltage-to-capacity slope, so the phone reads 25% but the actual cell voltage under modem or screen load drops below the shutdown threshold before the gauge catches up. It is not a faulty battery. One full discharge down to auto-off followed by a full charge resets the coulomb counter. After that cycle, reported percentage and actual cutoff voltage align correctly.

Device won't power on after sitting in storage with a dead battery

If a Hydro Vibe sits discharged for weeks or months, the cell voltage can fall below 2.5V. At that point the phone's BMS locks out to prevent cell damage, and the device shows no response — no boot logo, no charging indicator. Connect the phone to a low-current charger (a standard 5V USB wall adapter, not a fast charger) and leave it for 20–30 minutes before pressing power. The BMS needs a trickle input to exit lockout before it will allow normal charge current. If the screen still shows nothing after 30 minutes, disconnect, wait 60 seconds, and reconnect — this resets the charge IC handshake.

Frequently Asked Questions

Why is my Hydro Vibe showing the wrong battery percentage after I put in the new cell?

The fuel gauge IC in the C6725 calibrates its coulomb counter to the discharge curve of whatever cell it last learned. After a swap, the old curve is still stored, so reported percentage drifts from actual cell voltage — especially in the 30–70% range. Run one full discharge to auto-off, then charge uninterrupted to 100% without fast charging enabled. That single cycle rewrites the counter to match the new cell, and percentage accuracy stabilises from the next cycle onward.

Fast charging stopped working the first time I plugged in after replacing the battery — what happened?

On the first charge cycle after a cell swap, the Hydro Vibe's charge IC runs a brief validation pass on the new cell's impedance before it negotiates a higher charge rate. If the handshake times out or the IC detects an uncalibrated cell, it drops back to standard 5V input and stays there for that session. Unplug, wait 30 seconds, and reconnect — the IC resets and renegotiates. Fast charging typically resumes normally on the second or third plug-in once the IC has seen a partial cycle on the new cell.

The phone feels warm near the battery while charging — is that a problem with the replacement cell?

A new high-impedance cell produces slightly more heat during the first few charge cycles than a worn cell does. This is expected — internal resistance on a fresh lithium cell drops after the first few full cycles, and charge heat comes down with it. If the back of the phone is warm but not hot to the touch, that is within normal range. If it becomes uncomfortable to hold or the phone throws a temperature warning, stop charging and let it cool to room temperature before reconnecting — then charge at standard rate rather than fast charge until the cell breaks in over two to three cycles.
