Fits AudioVox PPC6800 smartphone, replaces OEM battery 35H00077-00M.
3.7V and 2600mAh lithium-ion cell powers calls, messaging, and PDA functions on this Windows Mobile device.
Connector slides straight into the battery slot with a single locking tab securing the pack horizontally.
We bench-tested this cell in a PPC6800 with a fresh BMS handshake; the fuel gauge IC initialized on first charge without cutoff errors.
On first use after installation, run one complete discharge-charge cycle without opening applications — this lets the coulomb counter recalibrate against the new cell curve before heavy modem load.

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.

AudioVox PPC6800 — 3.7V Li-ion 2600mAh Replacement Battery (35H00077-00M)

This 3.7V, 2600mAh Li-ion cell replaces the original battery in the AudioVox PPC6800 and PPC-6800. It fits the Windows Mobile PDA-phone directly, using the same OEM-matched connector and cell format. Capacity figures come from the product data sheet — 9.62Wh at 3.7V nominal.

  • PPC6800 and PPC-6800 compatibility: Both model designations share the same battery bay dimensions, connector pinout, and BMS handshake voltage. The 35H00077-00M and 35H00077-02M part numbers are cross-compatible across PPC6800 production runs — the cell and protection circuit are identical.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the PPC6800 platform. The BMS accepted the charge IC handshake without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold during a controlled deep-discharge test.
  • Fuel gauge recalibration on first cycle: After installing this cell, run one full discharge to automatic shutdown and then charge uninterrupted to 100% before normal use. The PPC6800's fuel gauge IC was calibrated to the old cell's discharge curve — skipping this step causes the percentage display to read inaccurately from the first charge.

Sudden shutdown at 20–30% on the PPC6800 after a cell swap

The PPC6800 combines modem, screen, and PDA functions in one load cycle. When the display and radio draw peak current simultaneously, a new cell with an uncalibrated fuel gauge can report 25% remaining while the actual terminal voltage drops below 3.2V under load. The BMS reads that voltage sag as a low-cell condition and cuts output immediately. Running one full calibration cycle after installation closes the gap between the coulomb counter's estimate and real cell state.

Battery percentage jumping erratically in the first few days

This is the fuel gauge IC recalibrating against the new cell's discharge curve. The original firmware-stored curve was built around the aged cell it shipped with — a fresh 2600mAh cell has a steeper, higher-capacity curve that the IC hasn't mapped yet. Erratic jumps of 5–15% are normal in the first two to three cycles. After two full discharge-charge cycles, the coulomb counter stabilises and percentage reporting becomes consistent.

Frequently Asked Questions

My PPC6800 won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?

Most likely the cell discharged below the BMS lockout threshold, typically around 2.5V per cell, which triggers a protection circuit shutdown to prevent damage. Connect the phone to a wall charger — not a PC USB port — and leave it for 30 to 45 minutes without attempting to power on. The charge IC on the PPC6800 trickle-charges a locked-out cell at a reduced rate until it recovers above the re-initialisation threshold, at which point the BMS releases and normal charging resumes. If the battery indicator shows no activity after an hour on a wall charger, check that the charger output is at least 5V 1A.

The PPC6800 feels warm near the battery compartment while charging the new cell — is that normal?

A new high-impedance cell generates more heat during the first few charge cycles than a broken-in one. The charge IC pushes current into a cell with higher internal resistance until the cell's impedance drops after two or three full cycles. Warm to the touch at the back cover is within normal range — if the device becomes hot or the screen dims during charging, remove the battery and let both cool to room temperature before reconnecting. After the third full charge cycle, heat during charging should reduce noticeably.

The PPC6800 powered on fine but the OS shows 100% immediately after install — then drops to 60% within minutes without heavy use. What's wrong?

The fuel gauge IC is reading a stored discharge curve from the previous cell and applying it to the new 2600mAh cell — the two curves don't match, so the percentage reading is unreliable from the first boot. The fix is one controlled full cycle: use the device normally until it shuts down automatically, then charge to 100% without interruption. The coulomb counter rewrites its reference points against the new cell's actual voltage curve during that cycle, and the percentage display will track correctly from that point forward.
