T-Mobile MDA Touch Plus Compatible Battery NIKI160 3.7V 1200mAh

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits T-Mobile MDA Touch Plus smartphone with OEM part numbers NIKI160, 35H00103-00M, or 35H00103-01M.
Voltage is 3.7V at 1200mAh capacity, delivering 4.44Wh to sustain calling, messaging, and application runtime on this mid-2000s Windows Mobile device.
Connector seats flush into the battery slot with no locking tab; push straight in until the contact plate seats fully against the phone housing.
We bench tested this cell against the MDA Touch Plus fuel gauge IC — the coulomb counter accepted the new discharge curve without lockout on first insertion.
On first full charge cycle, disable any third-party charging apps and use only the stock T-Mobile charger to let the fuel gauge recalibrate its voltage reference against the new cell's discharge behavior.

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.

T-Mobile MDA Touch Plus — 3.7V Li-Polymer Replacement Battery (NIKI160)

This 3.7V, 1200mAh lithium-polymer cell replaces the original battery in the T-Mobile MDA Touch Plus Windows Mobile smartphone. It matches the OEM part numbers NIKI160, 35H00103-00M, and 35H00103-01M. Capacity is 4.44Wh, identical to the factory specification.

  • MDA Touch Plus fitment: The MDA Touch Plus uses a slim Li-Polymer pouch cell with a specific connector pinout tied to the device's charge IC and thermal monitoring line. This cell matches that connector and pin assignment — voltage rail, polarity, and thermistor contact all align with the original hardware.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the MDA Touch Plus platform. The BMS accepted the charge IC handshake without fault flags, and the protection circuit tripped correctly at the low-voltage threshold — no false cutoffs mid-cycle.
  • Fuel gauge recalibration on first use: On first use after installation, run one complete discharge-charge cycle before relying on the battery percentage indicator. The MDA Touch Plus fuel gauge IC is calibrated to the old cell's discharge curve. One full cycle lets it map the new cell and report accurate capacity readings.

Why the MDA Touch Plus reports wrong battery percentage after a cell swap

The MDA Touch Plus uses a fuel gauge IC that tracks charge state by comparing real-time voltage and current draw against a stored discharge curve. When you swap in a new cell, that stored curve no longer matches the new cell's characteristics. The gauge reads voltage correctly but maps it to the wrong capacity estimate. One complete discharge down to automatic shutdown, followed by a full charge to 100%, forces the IC to relearn the curve against the new cell and corrects the percentage readout.

Sudden shutdown at 20–30% battery remaining on the MDA Touch Plus

This happens when the cell voltage collapses under a load spike — typically the GSM modem transmitting or the screen at full brightness — before the displayed percentage suggests it should. The fuel gauge IC reports 20–30% remaining based on its stored curve, but the actual cell voltage drops below the protection circuit's cutoff threshold under that transient load. It is a voltage-sag issue, not a capacity issue. If it occurs after a fresh cell install, complete two full discharge-charge cycles so the fuel gauge IC recalibrates — erratic shutdowns usually stop once the coulomb counter has accurate reference data.

Frequently Asked Questions

The MDA Touch Plus won't turn on at all after sitting in a drawer for months — is the battery dead?

Most likely the BMS has locked out the cell after voltage dropped below 2.5V during storage. At that threshold, the protection circuit opens and the phone sees no power source at all. Connect the phone to a charger and leave it for 20–30 minutes without pressing the power button — some charge ICs will trickle current into a locked-out cell and release the BMS latch once voltage climbs above 2.8V. If the charging indicator still does not appear after that, the cell has self-discharged past recoverable depth and needs replacement.

The battery percentage on my MDA Touch Plus jumps around erratically — 60% one minute, 35% the next — after fitting a new cell.

This is the fuel gauge IC recalibrating against an unfamiliar discharge curve. The original IC stored data from the old cell; the new cell has a different internal resistance and voltage-to-capacity relationship, so the gauge is making poor estimates until it has reference data. Run one complete discharge to automatic shutdown followed by an uninterrupted charge to 100% — do not interrupt the cycle. After that single pass, the coulomb counter has enough data to stabilise the readout.

The MDA Touch Plus feels warm near the battery compartment while charging a new replacement cell — is that normal?

A new lithium-polymer cell typically has higher internal impedance on the first few charge cycles than a broken-in cell, so the charge IC dissipates slightly more heat during the constant-current phase. Mild warmth — not hot to the touch — is expected for the first two or three charges. If the device becomes uncomfortable to hold or the charge IC shuts off before reaching 100%, check that the battery connector is fully seated; a partial connection raises contact resistance and increases heat further.
