L13D1P32 Lenovo IdeaPad A8 Replacement Battery 3.8V 4250mAh

Lenovo IdeaPad A8 / A5500 / TAB3 8 — 3.8V Li-Polymer Replacement Battery (L13D1P32)

This is a 3.8V, 4250mAh (16.15Wh) Li-Polymer battery for the Lenovo IdeaPad A8, IdeaPad A8-50, IdeaPad A5500, and TAB3 8 tablets. It uses OEM part number L13D1P32 and connects directly to the tablet's main board charge IC. Dimensions are 121.00 × 99.85 × 2.90mm — confirm these against your existing cell before ordering.

• IdeaPad A8 and A5500 compatibility: These models share the same flat-cell form factor, 3.8V nominal voltage rail, and ZIF connector orientation. The L13D1P32 part number covers the full group — the BMS handshake requirements are identical across the A8, A8-50, A5500, and TAB3 8 variants.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an IdeaPad A8-50. The BMS accepted the first charge without error, the protection circuit tripped correctly at low-voltage cutoff, and cell temperature stayed within spec throughout the load test.
• Fuel gauge recalibration after swap: After fitting this battery, run the tablet down to automatic shutoff — not a manual power-off — then charge in one uninterrupted session to 100%. This forces the fuel gauge IC to recalibrate against the new cell and clears the inaccurate percentage readings that appear immediately after a battery swap.

Tablet shutting down at 15–25% remaining after battery replacement

The IdeaPad A8 and A5500 combine a high-brightness display with active WiFi — that combined load pulls current fast enough to expose a steep voltage cliff in a degraded or unrecalibrated cell. A new cell with an uncalibrated fuel gauge hits that cliff before the percentage readout catches up, so the tablet cuts power while showing charge remaining. The fix is a single full discharge-to-shutoff cycle followed by an uninterrupted charge to 100%. After one complete cycle the fuel gauge maps the new cell's voltage curve and the premature shutdowns stop.

Fast charging unavailable after fitting a new L13D1P32 cell

The IdeaPad A8 series uses a proprietary charge negotiation sequence between the charge IC and the battery's BMS. On a fresh cell the BMS has not yet completed an accepted charge cycle, so the charge IC defaults to standard rate as a precaution. This is not a fault with the new battery. Plug into the original Lenovo charger — not a third-party adapter — and allow the first full charge to complete without interruption. Fast charge availability returns once the IC and BMS have completed that initial handshake cycle.
