Product Description
he AP16M5J is a 2-cell Li-ion compatible replacement battery originally fitted to Acer’s value-segment lineup — a family of machines that has shipped in exceptionally high volumes to education buyers, SME fleets, and budget-conscious consumers across North America, Europe, and Southeast Asia since 2016. By 2025, these units are well past their first battery replacement window. Repair centers and IT fleet managers sourcing compatible laptop batteries in bulk will find consistent pull-through demand for this part number, particularly in school district refresh programs where Aspire 1 and Aspire 3 units were deployed at scale.
What most B2B buyers can’t find in one place is a China notebook battery manufacturer who combines verified cross-compatibility data, transparent cell grading, and a workable wholesale program. That’s exactly what this listing addresses.

Features & Advantages
🔋 2-Cell Architecture — Built for High-Volume Repair Throughput
Unlike the 3-cell or 4-cell packs used in premium Acer lines, the AP16M5J uses a compact 2-cell configuration. For repair shops cycling through back-to-back A314/A315 jobs, the direct-swap installation takes under 4 minutes per unit — back cover, three screws, done. Repair centers that keep AP16M5J in regular stock report it as one of their highest-turnover Acer SKUs.
⚡ Verified 37Wh Capacity — Not a Relabeled Downgrade
Confirmed specification: 7.7V / 37Wh / 4810mAh. Every production batch is tested under a full-discharge cycle at 25°C before packing. Units that measure below 36.5Wh on first-cycle discharge do not ship. This threshold matters directly for repair shops offering 90-day post-service battery warranties to their end customers.
🔌 BIOS Handshake Compatibility — Zero “Unknown Battery” Errors
Our replacement units use a PCB design with validated DeviceChemistry and ManufacturerName strings matching OEM parameters on Aspire BIOS versions through the latest 2024 EC updates. Repair distributors who have experienced the “plugged in, not charging” error with cheaper sources will find this resolved here. Grade A cells, verified firmware strings — the gap between a Grade A and Grade B cell shows up in BIOS recognition and cycle behavior, not just peak capacity.
🏫 A Preferred Replacement for Educational Fleet Batteries
The Aspire 1 and Aspire 3 were widely adopted across school districts and educational institutions in the US, UK, and Australia as affordable classroom devices. That deployment volume now translates into predictable **bulk replacement battery** demand as devices enter their 4–6 year service cycle. Whether you’re managing a repair program for a school district or stocking inventory for the education repair segment, AP16M5J is a reliable volume item to carry.
📦 Factory-Direct Supply — No Middleman, No Surprises
As a **laptop battery manufacturer in China** with direct production capabilities, we eliminate the distributor margin that inflates pricing on the secondary market. What this means for your business: stable per-unit pricing across quarters, consistent cell batch traceability, and the flexibility to place small trial orders before scaling up. **Fast shipping** on in-stock items — standard lead time is 3–5 business days after PO confirmation, with air freight documentation (UN38.3) prepared at the same time. Distributors, IT asset resellers, and **repair shop suppliers** are welcome to inquire about tiered pricing and private-label packaging options.

FAQ
Q1: Does the AP16M5J work with both A315-21 (AMD) and A315-51 (Intel) variants?
Yes. The AP16M5J is the OEM-specified battery for both AMD and Intel platform variants of the Aspire 3 A315 series. The hardware connector, PCB pinout, and BMS firmware strings are identical across both CPU platforms.
Q2: How do I confirm my laptop uses the AP16M5J before ordering?
Remove the back panel, locate the battery label, and check the P/N printed directly on the battery. Valid matches include: AP16M5J, KT.00205.004, KT.00205.005, or 2ICP4/80/104. Do not rely solely on laptop model number — some Aspire 3 sub-variants shipped with different batteries depending on region and production quarter.
Q3: What is the shelf life of an AP16M5J stored in warehouse before installation?
Li-ion batteries lose approximately 1–2% of capacity per month when stored at 15–25°C at 40–50% state of charge. Properly stored units remain within usable performance range for 12–18 months. We recommend rotating stock within 12 months of purchase date.
Q4: Can the AP16M5J be used while the laptop is plugged in permanently?
Technically yes, but prolonged trickle-charging above 95% SOC accelerates cell degradation. For device fleets kept permanently docked, we recommend enabling Acer’s built-in battery care mode (charge threshold at 80%) via the Acer Care Center utility if available on that firmware version.
Q5: What is the minimum order quantity for wholesale pricing?
We support small batch orders — please contact us directly for tiered pricing. Sample orders are also available for quality verification before committing to a larger purchase.
Q6: What is the lead time and how are bulk orders packaged for shipping?
For in-stock items, lead time is 3–5 business days after PO confirmation. Standard export packing: each battery in an ESD anti-static bag + foam insert, 20 pcs per carton. Custom white-label packaging and SKU barcoding are available on request. All shipments include UN38.3 compliance documentation for air freight.
