What is the lead time for a large AP20CBL bulk order of 500 units, and what are the shipping options for international delivery?

For a 500-unit order from current inventory, production and QC processing is approximately 5 to 7 business days. Air freight via DHL or FedEx typically takes 3 to 7 transit days for most markets. Sea freight is available for large orders to reduce per-unit cost, with 15 to 30 day transit depending on destination port. All shipments include UN38.3-certified lithium battery packaging with full air transport compliance documentation. Specify destination country and preferred Incoterm (FOB, CIF, or DDP) when inquiring and we will include a freight quote with the product quotation.

Acer AP20CBL 11.55V 53Wh AMD Ryzen Aspire 5 / Swift 3 / Chromebook 315 Replacement Battery Wholesale

Q: The Aspire Vero AV15-51 appears on compatibility lists for both the AP20CBL and AP19B5L. Which one should I order for my AV15-51 fleet?

Both are correct for different production variants of the same model. Acer manufactured the AV15-51 with two different power platforms: some units shipped with the AP20CBL (11.55V / 53Wh) and others with the AP19B5L (15.4V / 54.6Wh). Installing the wrong voltage unit will trigger BMS protection and the battery will not charge. For AV15-51 fleet procurement, open the back cover of a representative sample of devices and read the part number on the original battery label. Do not determine the required part number from the laptop model number alone. We stock both AP20CBL and AP19B5L and can assist with fitment verification.

Q: What is the difference between the part number codes 31CP5/82/70 and 3ICP5/82/70? Are these the same battery?

Yes, they refer to the same cell string. The 31CP5/82/70 and 3ICP5/82/70 notations are formatting variants of the same internal Acer cell configuration code: three cylindrical cells, 5mm diameter, 82mm length, 70mm width. Some Acer documentation and aftermarket sellers use one notation; others use the other. Both designate the same physical battery pack and should be treated as equivalent for procurement purposes.

Product Description

The AP20CBL is Acer’s primary battery platform for its 2021–2022 AMD Ryzen generation — the first Acer product cycle to consolidate consumer, rugged-eco, business-convertible, and ChromeOS education devices onto a common 11.55V / 53Wh / 3-cell power spec. The OEM part number AP20CBL (also coded KT.0030B.002, KT0030B002, and cell-string reference 31CP5/82/70) fits the Aspire 5 (A515-45, A515-45G, A515-46), Aspire 7 (A715-43G), Swift 3 (SF314-43, SF314-511), Aspire Vero (AV15-51 series), TravelMate Spin B3 (TMB311RNA-32), Chromebook 315 (CB315-4H), and Chromebook 512 (C852). The breadth of this list matters to wholesale buyers precisely because it spans four distinct procurement channels: consumer laptop repair shops, enterprise IT departments managing AMD-platform Acer fleets, education IT teams running Chromebook deployments, and repair vendors servicing the Aspire Vero’s growing eco-product installed base.

A clarification that competitor pages universally omit: the Aspire Vero AV15-51 appears on compatibility lists for both the AP20CBL (11.55V) and the AP19B5L (15.4V). These are not interchangeable. Acer produced the AV15-51 in multiple regional and batch variants — some shipped with the 15.4V / 54.6Wh AP19B5L platform, others with the 11.55V / 53Wh AP20CBL platform. The voltage difference is significant: installing the wrong unit will trigger BMS protection and the battery will not operate. Procurement teams servicing an AV15-51 fleet must verify the original battery label (AP20CBL vs AP19B5L) before placing a bulk order — the model number alone is insufficient to determine which platform applies.

For education-focused buyers: the Chromebook 315 CB315-4H is a Google-certified education device deployed at scale in K-12 environments across North America, Australia, and Western Europe. Unlike Windows laptops, ChromeOS devices report battery health through Google’s own diagnostics system, and the CB315-4H uses the same BMS protection architecture as the AP20CBL pack in other Acer AMD-platform devices. Bulk AP20CBL orders for Chromebook fleet repair have a distinct purchasing profile — school IT teams typically procure in fiscal-year cycles, require formal quotation and PO documentation, and often need split deliveries across multiple campus locations. We support all of these procurement structures.

Features & Advantages

✅ ⚡ 3S1P at 11.55V: AMD Ryzen Platform’s Optimized Discharge Curve

The AP20CBL operates at 11.55V nominal — 0.15V higher than the AP18C4K’s 11.4V. This reflects Acer’s voltage tuning for the higher sustained power draw of AMD Ryzen 5000 series CPUs under load. The 3S1P cylindrical Li-ion configuration (three cells in series, single parallel string) provides stable voltage output during the Ryzen platform’s characteristic bursty power demand profile, reducing sag events that trigger low-battery warnings at higher-than-actual charge states.

✅ 🖥️ Seven-Line Coverage: Consumer, Business, Education, and Eco in One SKU

One AP20CBL stock position covers Aspire 5, Aspire 7, Swift 3, Aspire Vero, TravelMate Spin B3, Chromebook 315, and Chromebook 512. This is the only Acer 2021–2022 AMD-generation battery that spans both Windows and ChromeOS devices simultaneously, making it the highest-breadth single SKU for repair operations servicing mixed Acer fleets from that production window.

✅ 🔍 AV15-51 Platform Split: The Ordering Error Most Wholesale Pages Don’t Flag

The Aspire Vero AV15-51 shipped with either the AP20CBL (11.55V) or AP19B5L (15.4V) depending on production batch and regional variant. Both part numbers appear on AV15-51 compatibility lists across competing sellers — without any warning. Voltage mismatch disables charging entirely. Confirm the original battery label on AV15-51 units before any bulk order for this series. We supply both AP20CBL and AP19B5L and can clarify fitment from device serial numbers on request.

FAQ

Q1: The Aspire Vero AV15-51 appears on compatibility lists for both the AP20CBL and AP19B5L. Which one should I order for my AV15-51 fleet?
A1: Both are correct — for different production variants of the same model. Acer manufactured the AV15-51 with two different power platforms: some units shipped with the AP20CBL (11.55V / 53Wh) and others with the AP19B5L (15.4V / 54.6Wh). Installing the wrong voltage unit will trigger BMS protection and the battery will not charge. For AV15-51 fleet procurement, open the back cover of a representative sample of devices and read the part number printed on the original battery label. Do not determine the required part number from the laptop model number alone. We stock both AP20CBL and AP19B5L and can assist with fitment verification.

Q2: We manage a school Chromebook 315 CB315-4H fleet. Does the AP20CBL work with ChromeOS battery management, and do you support institutional purchase orders?
A2: Yes on both counts. The AP20CBL is the OEM-spec battery for the CB315-4H and operates normally with ChromeOS battery health diagnostics. The BMS communication protocol is compatible with ChromeOS’s power management system — no firmware or pairing issues. For institutional procurement: we accept formal purchase orders, issue proforma invoices, support split deliveries across multiple campus locations, and can pre-confirm stock reservation for fiscal-year procurement cycles. Contact us with your fleet size and delivery schedule to begin the quotation process.

Q3: What is the difference between the part number codes 31CP5/82/70 and 3ICP5/82/70? Are these the same battery?
A3: Yes, they refer to the same cell string. The 31CP5/82/70 and 3ICP5/82/70 notations are formatting variants of the same internal Acer cell configuration code — three cylindrical cells, 5mm cell diameter, 82mm length, 70mm width. Some Acer documentation and aftermarket sellers use one notation; others use the other. Both designate the same physical battery pack. When cross-referencing part numbers for procurement, treat them as equivalent.

Q4: How does the AP20CBL compare to the AP18C4K? Both appear on some Aspire 5 compatibility lists.
A4: They are not interchangeable. The AP18C4K is rated at 11.4V / 48Wh / 4200mAh and covers the 2018–2021 Intel-platform Aspire 5 (A515-43, A515-44, A515-54, A515-56). The AP20CBL is rated at 11.55V / 53Wh / 4590mAh and covers the 2021–2022 AMD-platform Aspire 5 (A515-45, A515-46). The voltage and capacity differ, and the Aspire 5 model numbers they fit are distinct generations. If your fleet spans both Intel and AMD Aspire 5 generations, you need both SKUs. Confirm by checking the original battery label in each device.

Q5: Can you provide capacity test data for bulk AP20CBL orders? Our IT procurement policy requires incoming QC documentation.
A5: Yes. Bulk orders above minimum quantity include per-batch discharge reports showing measured Wh output against the 53Wh rated spec, along with cell lot traceability records. These are issued before shipment confirmation. For institutions with formal incoming inspection procedures, we can also provide a certificate of conformance and the relevant compliance documentation (CE declaration, RoHS certificate) as a bundled pre-shipment package. Specify documentation requirements at the quotation stage.

Q6: What is the lead time for a large AP20CBL bulk order — for example, 500 units — and what are the shipping options for international delivery?
A6: For a 500-unit order from current inventory, production and QC processing time is approximately 5–7 business days. Shipping options depend on destination: air freight (DHL/FedEx) for most markets with an estimated 3–7 transit days; sea freight available for large orders to reduce per-unit freight cost, with 15–30 day transit depending on destination port. All shipments include UN38.3-certified lithium battery packaging with full air transport compliance documentation. We can provide a freight quote alongside the product quotation — specify destination country and preferred Incoterm (FOB/CIF/DDP) when inquiring.
