About this replacement
Asus ZenPad 7.0 Z370C — 3.8V Li-Polymer Replacement Battery (0B200-01510100)
This 3.8V, 3250mAh Li-Polymer battery replaces the original cell in the Asus ZenPad 7.0 Z370C and related ZenPad models including the Z370KL, Z370CG, and M700KL. It matches OEM part numbers 0B200-01510100 and C11P1425. The battery slots into place using the original connector and flex cable routing.
- ZenPad 7.0 series compatibility: The Z370C, Z370KL 1B, Z370CG 1B, and M700KL share the same 3.8V flat-pack cell format, connector pinout, and BMS handshake protocol — which is why one SKU covers all of them. The charge IC on each board expects the same voltage profile and NTC thermistor response.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on a Z370C board. The BMS accepted the new cell without error flags, the charge IC stepped through CC/CV phases correctly, and the protection circuit tripped at the expected low-voltage cutoff threshold.
- Fuel gauge recalibration after swap: After installing this battery, run one full discharge to automatic shutoff, then charge uninterrupted to 100% without using the tablet. The fuel gauge IC calibrates its capacity model against the new cell during this cycle — skipping it causes inaccurate percentage readings for the first several days of use.
ZenPad Z370C shutting down at 15–25% remaining
This shutdown pattern is a voltage-cliff issue, not a faulty cell. When the display backlight and Wi-Fi radio draw simultaneously, the combined load pulls the cell voltage down sharply near the bottom of the discharge curve. The board's undervoltage protection trips before the fuel gauge reaches zero. One full calibration cycle — full discharge to shutoff, then uninterrupted charge to 100% — lets the fuel gauge IC map the actual voltage cliff of the new cell and resolve premature cutoffs.
Fast charging unavailable after battery replacement on the Z370C
After a battery swap, the charge IC sometimes defaults to standard 5V/1A until it completes one accepted full charge cycle with the new cell. This is a protocol handshake reset, not a hardware fault. Plug in the original Asus charger — not a generic USB adapter — and allow the tablet to charge from near-zero to 100% without interruption. After that single cycle, fast charge negotiation resumes at the correct voltage and current parameters.
