Verizon Trophy 3.7V 2200mAh Replacement Battery Li-ion

Up to 20% off
New arrival
Sale priceFrom $25.99 USD Regular price $31.99
Shipping calculated at checkout.
Fits Verizon Trophy and MWP6985 models replacing original 3.7V lithium-ion cell.
This 3.7V 2200mAh cell delivers 8.14Wh — sufficient for daily operation on the Trophy smartphone before degradation forces replacement cycles.
Connector seats vertically into the battery slot with a single locking tab; orientation marked on the cell housing matches the compartment contact layout.
We ran full discharge cycles on the bench; the BMS accepted charge current without fault codes and held voltage stable under moderate load until cutoff.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the fuel gauge IC recalibrates against this cell's discharge curve.

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.

Verizon Trophy MWP6985 / MWP6985VW — 3.7V Li-ion Replacement Battery

This 3.7V 2200mAh Li-ion battery replaces the original cell in the Verizon Trophy smartphone, covering model numbers MWP6985 and MWP6985VW. It matches the factory voltage rail and physical footprint of the OEM unit. Capacity is 2200mAh (8.14Wh) as rated.

  • Trophy MWP6985 and MWP6985VW compatibility: Both variants share the same battery bay dimensions, connector pinout, and 3.7V nominal voltage rail. The BMS handshake requirements are identical across both model numbers, so one cell covers the full Trophy line.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on Trophy hardware. The BMS accepted the cell without flagging a fault, and the charge IC completed a full constant-current/constant-voltage charge sequence without thermal cutoff.
  • Fuel gauge recalibration after installation: On first use, disable any fast-charge adapter and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's actual discharge curve before high-current charging is applied to an uncalibrated cell.

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

The Trophy's fuel gauge IC stores the discharge curve of the original cell in its memory. When a new cell goes in, that stored curve no longer matches real voltage behaviour. Under modem or display load, the cell voltage drops faster than the gauge predicts, and the phone cuts power before the reported percentage reaches zero. This is a calibration mismatch, not a defective battery. One full discharge to 0% followed by a complete charge cycle writes a new baseline to the coulomb counter. After that cycle, the shutdowns stop.

Phone reports wrong battery percentage after cell replacement

The fuel gauge IC on the Trophy calibrates its percentage model against accumulated charge and discharge data from the previous cell. A new cell has different internal resistance and a slightly different discharge slope, so the gauge reads off-target — often showing jumps or a stuck percentage. The fix is a single uninterrupted discharge to automatic shutdown, then a full charge without interruption. After that cycle, the gauge recalibrates and percentage reporting stabilises to within a few points of actual capacity.

Frequently Asked Questions

My Verizon Trophy won't power on at all after sitting in a drawer with this replacement battery installed — is the battery dead?

When a Li-ion cell drops below roughly 2.5V from extended storage without a charge, the BMS locks out to prevent unsafe charging of a deeply discharged cell. Plug the Trophy into a wall adapter — not a PC USB port, which may not supply enough current to trigger recovery — and leave it connected for at least 20 minutes before attempting to power on. If the battery has not self-discharged past the hard lockout threshold, the BMS will accept a trickle charge and the phone will boot normally. If the screen stays black after 30 minutes on a wall adapter, check that the adapter outputs at least 1A at 5V.

The Trophy feels warm near the battery during the first few charges — is the new cell overheating?

A new Li-ion cell has higher internal impedance than a well-cycled cell, so the charge IC pushes slightly more heat into it during the first few charge cycles. This is normal and the warmth should reduce noticeably after three to four full cycles as impedance settles. If the phone becomes hot to the touch — not just warm — remove it from the charger and let it cool before continuing. Use the original wall adapter rather than a high-current third-party charger for the first three cycles to keep charge current within the range the Trophy's charge IC was set for.

The battery percentage on my Trophy jumps around erratically — it dropped from 60% to 15% in seconds and then climbed back up.

Erratic percentage jumps are a fuel gauge IC calibration issue, not a sign of a faulty cell. The gauge's internal model is still mapped to the old cell's discharge curve, so when load spikes — modem transmission, screen brightness burst — voltage dips faster than the model expects and the percentage snaps to a lower value. Let the Trophy discharge to automatic shutdown, then charge uninterrupted to 100% using the stock charger. That single full cycle forces the coulomb counter to resync against the new cell's actual voltage behaviour, and the jumping stops after that.
