About this replacement
Samsung A10 / VM8000 Series — 14.8V Li-ion Replacement Battery (346C61A)
This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for the Samsung A10, VM8000, and VM8100 notebooks. It slots into the original battery bay and restores portable power when the factory cell no longer holds charge. Use OEM part numbers 346C61A, SSB-690L8-E, or SSB690ELS/E to confirm fitment against your existing battery label.
- A10, VM8000, and VM8100 compatibility: These three models share the same 14.8V battery rail, physical form factor, and BMS communication protocol — a single cell revision covers all three without any adapter or modification.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and load cycles on the A10 platform. The BMS handshook correctly, charge current tapered as expected at full capacity, and no protection trips occurred under sustained CPU and display load.
- Post-install calibration on Samsung A10: After fitting this battery, run one full discharge until the laptop hibernates on low-battery cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after fitting a new cell
The Samsung A10 BIOS reads health data stored in the battery's EEPROM, not live cell chemistry. When a new cell arrives, the EEPROM values do not match the BIOS's logged charge history, so the system flags the battery as degraded even though the cell is new. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS to rewrite its reference data against the new cell. After one or two completed cycles, the health indicator corrects itself without any firmware update.
Laptop shuts down hard at 20–30% battery shown on screen
This is a voltage cliff, not a capacity fault. When the CPU and display draw full load simultaneously, cell voltage drops sharply in the 20–30% state-of-charge window — faster than the fuel gauge IC can track. The BMS sees voltage fall below its cutoff threshold and trips before the OS gets a low-battery warning. The fix is calibration: discharge fully to hibernate cutoff, then charge to 100% in one uninterrupted session. This gives the fuel gauge IC accurate end-points to map against, and the premature shutdowns stop once the IC has two or three calibrated cycles logged.
