I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

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.

Nokia 5 / 5 Dual SIM — 3.85V Li-Polymer Replacement Battery (HE336 / HE321)

This is a 3.85V, 2900mAh Li-Polymer replacement battery for the Nokia 5 and Nokia 5 Dual SIM smartphones. It covers all regional variants including TD-LTE and LATAM models. Fits where OEM parts HE336 and HE321 are listed.

  • Nokia 5 variant coverage: All Nokia 5 Dual SIM variants — standard, TD-LTE, and LATAM — share the same battery bay dimensions, connector pinout, and BMS communication protocol. One cell fits the full lineup without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Nokia 5 unit. The BMS handshake completed correctly, charge current stepped down as expected near full capacity, and the protection circuit tripped cleanly at the low-voltage threshold.
  • Fuel gauge recalibration on first use: After installation, disable fast charging and run one full discharge-to-charge cycle at standard rate. This lets the fuel gauge IC map the new cell's discharge curve before fast charge pushes high current into an uncalibrated cell — preventing early percentage jumps.

Sudden shutdown at 20–30% on the Nokia 5 after a cell swap

The Nokia 5 fuel gauge IC retains the discharge curve of the previous cell in memory. When a new cell with a different internal impedance is installed, the IC misreads the actual state of charge. Under peak loads — mobile data handoff, screen-on burst — the new cell's voltage drops faster than the IC predicts, and the phone shuts down before the displayed percentage reaches zero. One full discharge cycle from 100% to auto-off, then a full charge, resets the coulomb counter against the new cell's actual curve. After that cycle, shutdown behaviour at low charge normalises.

USB fast charge not activating on the first cycle after replacement

On first connection after installation, the Nokia 5 charge IC may negotiate only standard 5V charging rather than the higher voltage fast-charge profile. This happens because the BMS on a new cell defaults to a conservative handshake until it has completed one initialisation cycle with the host device. Plug in using the original Nokia charger and allow the first charge to complete fully at whatever rate the phone accepts. Fast charge negotiation typically activates correctly on subsequent connections once the BMS and charge IC have exchanged a full session.

Frequently Asked Questions

My Nokia 5 shows 25% battery then just switches off — is the new battery faulty?

It is not faulty. The fuel gauge IC inside the Nokia 5 is calibrated to the old cell's discharge curve, so it misjudges how quickly voltage drops under load on a fresh cell. Under modem or screen load, the new cell's voltage sags past the shutdown threshold before the displayed percentage catches up. Run one uninterrupted discharge from 100% to automatic shutdown, then charge fully without interruption — the coulomb counter resets against the new cell and the cutoff point shifts back to the correct range.

The battery percentage on my Nokia 5 jumps around erratically after I put the new cell in — what causes that?

The Nokia 5 fuel gauge IC uses a stored discharge model to estimate state of charge. A replacement cell has different internal impedance characteristics than the aged original, so the IC's estimates are off until it has enough data to recalculate. The percentage stabilises after one or two complete discharge-charge cycles at standard charge rate — each cycle gives the IC a full set of voltage and current data to refine its model. After two cycles, erratic jumping typically stops.

My Nokia 5 won't power on at all after the replacement battery sat unused in the phone for a few weeks — how do I recover it?

If the cell discharged below approximately 2.5V during storage, the BMS enters a lockout state to prevent damage and the phone will not respond to a normal power button press. Connect the phone to a wall charger — not a PC USB port — and leave it for at least 20–30 minutes without pressing anything. The charge IC trickle-charges the cell up through the BMS recovery threshold; once voltage clears roughly 3.0V, the BMS unlocks and normal charging resumes. If the charge indicator light does not appear within 45 minutes, try a different cable and confirm the charger outputs at least 1A.
