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.

ZTE Blade A462 / A310 — 3.8V Li-Polymer Replacement Battery (ICP37/54/72SA)

This 3.8V 2200mAh lithium-polymer cell replaces the original battery in the ZTE Blade A462 and Blade A310 smartphones. It matches OEM part numbers ICP37/54/72SA and 365371PLV. Rated at 8.36Wh, it restores full power to calls, messaging, apps, and display functions when the original cell has degraded or stopped holding a charge.

  • Blade A462 and A310 compatibility: Both models share the same battery bay dimensions, voltage rail, and connector pinout. The BMS on each device uses the same charge termination threshold, so one cell works across both without modification.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on a Blade A462 unit. The BMS accepted the cell without fault codes, charge termination triggered correctly at 4.35V, and protection cutoff engaged at the expected low-voltage threshold.
  • Fuel gauge recalibration after installation: On first use after fitting this cell, disable fast charging and complete one full discharge down to automatic shutdown, then charge uninterrupted to 100%. This gives the fuel gauge IC one clean reference cycle against the new cell's discharge curve before any high-current charging session.

Why the Blade A462 reports wrong battery percentage after a cell swap

The Blade A462 uses a coulomb-counting fuel gauge IC that builds its capacity model from the original cell's charge and discharge history. When a new cell goes in, that stored model no longer matches the actual cell chemistry. The gauge reads state-of-charge against the old curve, so it can show 40% while the cell is actually close to cutoff voltage. One complete discharge-to-shutdown followed by an uninterrupted charge to 100% forces the IC to write a fresh capacity baseline against the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the cell voltage drops sharply under the load spike from the modem radio or display backlight — a voltage cliff the fuel gauge did not predict. The phone's hardware protection trips before the OS can log a low-battery warning. It is not a faulty cell; it is an uncalibrated gauge sending the wrong percentage to the OS. Run one full discharge cycle without interruption and let the phone shut down on its own at 0%, then charge to 100%. After that cycle, the gauge's voltage-to-percentage mapping aligns with the new cell and the early shutdowns stop.

Frequently Asked Questions

My ZTE Blade A462 won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?

Lithium-polymer cells in storage self-discharge slowly, and if the cell dropped below roughly 2.5V the BMS will have locked out to prevent damage. Connect the phone to a wall charger — not a PC USB port — and leave it for 20–30 minutes without pressing the power button. The charge IC needs to trickle current into the cell before the BMS will release lockout and allow the phone to boot. If the charging LED does not appear within 40 minutes, check the cable and adapter with another device before concluding the cell is faulty.

Fast charging stopped working on my Blade A462 right after I fitted this replacement battery — it only charges slowly now.

On the first cycle after a cell swap, the phone's charge controller can default to a conservative constant-current profile because the BMS on the new cell has no charge history logged. Complete one full charge to 100% at the slow rate without interrupting it. On the second and subsequent cycles the controller typically negotiates the higher current tier again once it has a completed charge event on record. If fast charging still does not resume after two full cycles, check that the adapter and cable are rated for the protocol the Blade A462 expects.

The battery percentage on my Blade A462 keeps jumping around erratically — it dropped from 60% to 11% in a few minutes then jumped back up.

Erratic percentage jumps after a cell swap come from the fuel gauge IC interpolating against a capacity model written for the old cell. The coulomb counter is reading accumulated charge correctly, but the voltage-to-percentage lookup table still references the worn cell's curve, so small load spikes cause large apparent drops. Run one complete uninterrupted discharge — let the phone shut itself off at 0% — then charge straight to 100% without unplugging. That single cycle rewrites the fuel gauge's reference points against the new cell and the jumping stops.
