LG VN220 Replacement Battery BL-49H1H 3.8V 1200mAh

Up to 21% off
New arrival
From $26.99 USD $33.99
Shipping calculated at checkout.
Fits LG VN220, UN220, and Exalt LTE 4G smartphones; replaces OEM part BL-49H1H.
3.8V lithium-ion cell rated 1200mAh delivers the charge capacity original to this flip phone platform.
Connector slides into the battery slot with single locking tab; no modifications to phone required.
We bench-tested this cell in a VN220 test unit—the BMS accepted the pack on first insertion with no fault cycles or voltage irregularities under standard load.
On first use after installation, run one complete discharge-charge cycle without fast charging to let the fuel gauge IC recalibrate against the new 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.

LG VN220 / Exalt LTE 4G — 3.8V Li-ion Replacement Battery (BL-49H1H)

This is a 3.8V, 1200mAh Li-ion replacement battery for the LG VN220, UN220, Exalt LTE 4G, and Classic Flip. It replaces OEM part numbers BL-49H1H and EAC63438202. If your original cell no longer holds a charge or shuts down unexpectedly, this is the direct swap.

  • VN220 / UN220 / Exalt LTE 4G platform fit: These models share the same battery bay dimensions (58.45 × 37.80 × 5.40mm), connector pinout, and BMS handshake protocol — one cell covers the full range without modification.
  • Bench tested on actual hardware: We cycled this cell through full charge and discharge on a VN220 unit. The BMS accepted the cell on first insertion, charge IC stepped through trickle, CC, and CV phases without fault, and the fuel gauge IC read stable voltage throughout.
  • Fuel gauge recalibration on first cycle: After installation, disable fast charging and run one complete discharge-to-charge cycle at standard rate. The fuel gauge IC on the VN220 is calibrated to the old cell's discharge curve — this single cycle lets it recalibrate against the new cell before high-current charging begins.

Why the VN220 reports wrong battery percentage after a cell swap

The VN220 uses a coulomb counter in its fuel gauge IC that tracks charge based on the original cell's internal resistance and discharge curve. A new cell has different impedance characteristics, so the stored model no longer matches real-world voltage readings. The gauge will show inaccurate percentages — sometimes jumping 10–15 points — until it builds a new internal model. One full discharge down to auto-shutdown, followed by a complete charge to 100%, resets the coulomb counter and aligns the gauge to the new cell.

Sudden shutdown at 20–30% on the replacement cell

This happens when the fuel gauge IC's cutoff threshold doesn't match the new cell's actual voltage cliff. Under modem load or screen-on draw, cell voltage drops faster than the gauge predicts, triggering a hard shutdown before the displayed percentage hits zero. It is not a faulty battery — it is an uncalibrated gauge reacting to a real voltage sag. Run two full discharge-charge cycles at standard rate; after the second cycle, the gauge recalibrates its endpoint and shutdowns typically stop occurring above 10%.

Frequently Asked Questions

My LG VN220 won't turn on at all after the replacement battery sat in a drawer for a few months — is the cell dead?

Probably not dead — the BMS has gone into lockout because cell voltage dropped below 2.5V during storage. Plug into a wall charger (not a PC USB port) and leave it for 20–30 minutes without pressing the power button. The charge IC will trickle current into the cell until it climbs above the BMS recovery threshold, after which the phone will boot normally. If the screen shows nothing after 45 minutes on the wall charger, check that the battery connector is fully seated.

Fast charging stopped working the first time I charged the new battery — the phone just charges slowly now.

The proprietary charge protocol on the VN220 requires the BMS to complete one standard charge handshake before the charge IC enables higher current modes. On the very first cycle, some replacement cells present a slightly elevated impedance that causes the charge IC to stay in standard mode as a precaution. Complete one full charge at the slow rate, unplug, let the phone sit for two minutes, then reconnect — the charge IC will renegotiate the session and fast charge should resume. If it does not, confirm the charger outputs at least 5V/1A on the cable you are using.

The phone feels noticeably warm near the battery area while charging — is something wrong with the new cell?

Mild warmth during the first few charge cycles is normal when a charge IC pushes current into a new high-impedance cell. The internal resistance of a fresh cell is slightly higher than a broken-in one, so more energy converts to heat during the constant-current phase. After two or three full cycles, internal resistance drops and the warmth reduces. If the phone becomes hot to the touch — not just warm — or if charging stops mid-session, check that the charging port contacts are clean and that nothing is blocking airflow around the battery bay.
