About this replacement
ZTE Blade A110 / A112 / A410 — 3.8V Li-ion Replacement Battery (Li3816T43P3h604550)
This is a 3.8V, 1200mAh Li-ion cell for the ZTE Blade A110, Blade A112, and Blade A410 smartphones. It replaces OEM part numbers Li3816T43P3h604550 and Li3715T42P3h604550. Swap it in when the original cell no longer holds charge or the phone shuts down unexpectedly under load.
- Blade A110 / A112 / A410 platform fit: All three models share the same 3.8V cell footprint, connector pinout, and BMS handshake protocol — one cell covers the full lineup without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the Blade A110 and confirmed the BMS accepted the handshake without triggering over-current protection on charge initiation or discharge cutoff.
- Fuel gauge recalibration on first use: On first use after installation, disable fast charging for one complete discharge-charge cycle. This lets the fuel gauge IC recalibrate against the new cell's discharge curve before high-current charging pushes current into an uncalibrated cell.
Sudden shutdown at 20–30% on the Blade A110 after a cell swap
The Blade A110 uses a coulomb-counter fuel gauge that was calibrated to the original cell's internal resistance profile. A new cell has different impedance characteristics, so the gauge misjudges the remaining charge. Under high-draw events — mobile data, screen-on bursts, or GPS — the cell voltage drops below the BMS cutoff threshold before the gauge reads zero. The fix is one full discharge to automatic shutdown, then a full uninterrupted charge to 100% with no interruptions. After that single cycle the gauge re-anchors its endpoints to the new cell.
Phone warm near the battery during the first few charges after replacement
A fresh cell has higher internal impedance than a broken-in one. The charge IC compensates by pushing slightly more voltage to maintain the target current, and that extra work generates heat. This is normal for the first two to three charge cycles as the cell's electrolyte settles. If warmth persists past the third full charge, check that the adhesive backing is not trapping heat against the rear case. By cycle four, surface temperature during charging should match what you saw with the original battery.
