Verizon VS910 Replacement Battery 3.7V 1500mAh Li-ion

Verizon VS910 Revolution 4G — 3.7V Li-ion Replacement Battery

This 3.7V, 1500mAh Li-ion battery replaces the original cell in the Verizon VS910, sold as the Revolution and Revolution 4G. It fits the same battery bay and uses the same three-contact connector as the factory unit. If your Revolution shuts down unexpectedly or no longer holds a charge through a full day, this cell directly addresses the degraded original.

• VS910 / Revolution / Revolution 4G fit: All three names refer to the same LG-built handset sold on Verizon's network. The battery bay dimensions, contact pitch, and BMS handshake protocol are identical across the VS910, Revolution, and Revolution 4G variants — one cell fits all three.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the VS910 platform. The BMS accepted the charge handshake without fault flags, and the protection circuit tripped correctly at the low-voltage cutoff threshold during deep discharge testing.
• Fuel gauge recalibration on first use: On first use after installation, disable fast charging and run one complete discharge-charge cycle at standard rate. This lets the fuel gauge IC map its coulomb counter against the new cell's discharge curve before any high-current charging pushes current into an uncalibrated cell.

Sudden shutdown at 20–30% on the VS910 after a cell swap

The VS910's fuel gauge IC stores a learned discharge curve from the original cell. When a new cell goes in, that stored curve no longer matches the actual voltage-to-capacity relationship of the replacement. The phone's modem and display draw current spikes that drop the new cell's voltage below the shutdown threshold even when the gauge still shows charge remaining. Running one full discharge to auto-off and then a full charge to 100% at standard rate forces the coulomb counter to resync. After that cycle, the reported percentage tracks accurately under load.

VS910 not powering on after the replacement battery sat in storage

Li-ion cells self-discharge in storage. If the replacement cell dropped below approximately 2.5V per cell during shipping or warehousing, the BMS enters lockout mode to prevent damage and the phone will not power on. Connect the phone to a wall charger — not a USB port — and leave it for 15 to 20 minutes without pressing the power button. The charge IC trickle-charges the cell back above the BMS recovery threshold, at which point the protection circuit releases and normal charging resumes.
