Gigabyte gSmart i GLH-H01 Replacement Battery 3.7V 950mAh

Up to 20% off
New arrival
From $29.99 USD $36.99
Shipping calculated at checkout.
Fits Gigabyte gSmart i, gSmart i+, and gSmart i (128) — replaces OEM GLH-H01 and A2K40-EBR270-C0R.
3.7V 950mAh cell delivers 3.52Wh to restore full-charge cycles on this compact smartphone.
Flat connector seats into the battery slot with a single locking tab oriented perpendicular to the PCB.
We ran the pack through a full discharge-charge cycle on a Gigabyte bench charger — BMS accepted input current without cutoff and held voltage under load draw.
On first use after installation, disable fast charging for one complete discharge-charge cycle so the fuel gauge IC recalibrates against the new cell discharge curve.

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.

Gigabyte gSmart i Series — 3.7V Li-ion Replacement Battery (GLH-H01)

This 3.7V 950mAh Li-ion cell replaces the original battery in the Gigabyte gSmart i, g-Smart i+, and gSmart i (128) smartphones. It fits all three variants sharing the GLH-H01 form factor, OEM part number A2K40-EBR270-C0R. Use the capacity figure from product data — 950mAh (3.52Wh) — when comparing against your original.

  • gSmart i variant compatibility: The gSmart i, g-Smart i+, and gSmart i (128) share the same connector pinout, cell dimensions (56.30 × 50.87 × 6.54mm), and BMS handshake — that is why one part number covers all three.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge under load. The BMS held cutoff at the correct low-voltage threshold and accepted charge current without tripping protection on the first cycle.
  • 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 its coulomb counter to the new cell's actual discharge curve before any high-current session begins.

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

A new cell has a slightly different voltage-vs-capacity curve than the aged cell the fuel gauge IC was calibrated to. When the phone demands peak current — active screen, modem transmitting, GPS — the cell voltage sags faster than the IC predicts. The IC sees a voltage reading that maps to a sudden cliff on the old curve and immediately shuts down to protect the cell. One full slow discharge cycle from 100% to 0% forces the coulomb counter to relearn the curve and eliminates most premature cutoffs.

Phone reads wrong battery percentage after replacement

The gSmart i's fuel gauge IC stores calibration data built against the original cell's impedance and discharge profile. After swapping to a fresh cell with lower internal resistance, those stored values no longer match reality — the percentage display drifts or jumps. Charge the phone fully to 100% until the charging indicator stops, then discharge to auto-shutdown without interruption. After that single cycle the IC resets its reference points and the percentage reading stabilises.

Frequently Asked Questions

My Gigabyte gSmart i won't turn on at all after sitting unused for a few months — is the new battery dead?

It is almost certainly a BMS lockout, not a dead cell. If the cell voltage dropped below roughly 2.5V during storage, the battery management system cuts all output to prevent damage. Plug the phone into a wall charger — not a PC port — and leave it for 20 to 30 minutes without pressing anything. Most BMS circuits recover from deep-discharge lockout once a trickle charge raises the cell back above the reinitialisation threshold.

Fast charging stopped working on my gSmart i the moment I fitted the replacement battery — what happened?

The phone's charge IC negotiates the fast-charge protocol with the battery's BMS on every boot. On a brand-new cell with higher impedance than a broken-in cell, some charge ICs fall back to standard rate on the first cycle as a precaution. Charge the phone once at standard rate to 100% and then restart the device. The protocol negotiation on the second cycle typically succeeds and fast charging resumes normally.

The gSmart i feels warm near the battery compartment while charging — should I stop charging?

Mild warmth on the first few charge cycles is normal. A new cell has higher internal resistance than a used one, and the charge IC pushes current into that resistance, generating more heat until the cell breaks in. If the phone feels hot enough to be uncomfortable to hold, stop charging and check that the charge voltage is not stuck above 4.2V using a battery monitor app. Normal break-in warmth clears after three to five full charge cycles as internal resistance drops.
