Produktbeschreibung
The 01AV448 is a 3-cell, 45Wh Li-ion replacement battery covering one of the widest single-P/N compatibility footprints in Lenovo’s ThinkPad E-series line — ten distinct model families spanning both 14-inch and 15.6-inch screen sizes, three AMD platforms (E485, E495, E585), and the full Intel E480 through E595 generation, plus the E14 and E15 Gen 1 introductions. Most parts listings for this P/N surface four to six model names; the E41-50 and E41-55 business-entry models, and the full E14/E15 Gen 1 type code range, are routinely absent from competitor compatibility lists despite being verified compatible devices.
Every model in this compatibility list shares the same 45Wh 3-cell specification and connector position — no sub-variant carries a different battery capacity, and AMD-platform units (E485, E495, E585) use the same physical battery as their Intel-platform siblings in the same chassis generation. For a repair depot or IT service centre processing a mixed E-series repair queue, this eliminates the need to sort incoming devices by CPU vendor before parts are picked: one stock line resolves both Intel and AMD units across the entire E4xx and E5xx range.
For procurement managers running institutional or corporate refresh programmes that include this device range, the single-SKU characteristic across a ten-model family means replenishment planning maps to one line item rather than requiring model-by-model battery sourcing. The practical pre-order boundary to track is generation scope: E14 Gen 2 and later, and E15 Gen 2 and later, use a different battery and are not covered by this P/N.

Merkmale und Vorteile
✅ 🔋 3-Cell Li-ion at the OEM-Specified 45Wh for the Full E-Series Range
Grade A 3-cell Li-ion cells deliver 45Wh at 11.1V across all ten compatible ThinkPad E-series and E4x platform variants — the exact voltage and capacity Lenovo specifies for this chassis generation. At 500 rated charge cycles, the service life budget per replacement unit exceeds the typical deployment window of the E480 through E595 generation in most corporate refresh programmes, which reduces the probability of a second battery replacement within a single device lifecycle and lowers the per-device total battery cost over a 3-to-4-year asset period.
✅ 🔗 Intel and AMD Platforms Share One Physical Battery SKU
The ThinkPad E485 (AMD Ryzen), E495 (AMD Ryzen), and E585 (AMD Ryzen) use the same 45Wh 3-cell battery — 01AV448 and its cross-reference P/Ns — as the Intel variants in the same generation. This cross-vendor compatibility is not consistently documented in parts listings, where AMD-platform models are frequently listed separately or omitted entirely. A repair depot stocking 01AV448 covers both Intel and AMD E-series units from a single bin position, with no need to maintain a separate AMD-specific battery SKU alongside the Intel one.
✅ ⚙️ ThinkPad E-Series EC Charge Authentication and BMS Architecture
On the ThinkPad E480 through E595 platform range, the Embedded Controller runs a charge authentication check at every connection of the AC adapter — a battery whose BMS smart chip does not respond within the expected window produces a “Battery not charging” notification in the system tray, even if the battery is physically seated. This unit’s BMS handles overcharge protection as the primary cutoff layer, closing the charge path at the cell pack voltage ceiling before the EC logs a fault event. Over-discharge cutoff and short-circuit interrupt operate as load-side protection functions, independent of the charge path control.
✅ 📦 Fleet Rollout Sequencing Simplified Across a Mixed E-Series Population
A fleet replacement programme covering any combination of E480, E490, E580, E590, E14 Gen 1, or E15 Gen 1 units draws from one battery SKU at the ordering stage, which compresses the purchase order to a single line item regardless of how many E-series model variants are represented in the fleet. This simplifies rollout sequencing: spare stock can be allocated from a single pool across all device types in the programme rather than held in separate model-specific bins. Wholesale orders are fulfilled from stock at low MOQ; mixed-SKU ordering is supported for depots combining this line with other ThinkPad battery SKUs in one consolidated shipment.
✅ 🔍 E14 Gen 1 and E15 Gen 1 Coverage Absent from Most Parts Listings
The ThinkPad E14 Gen 1 (Type 20RA, 20RB) and E15 Gen 1 (Type 20RD, 20RE) are verified compatible with 01AV448 — they share the same battery bay, connector, and 45Wh specification as the E480-through-E595 range. These two models appear in the Lenovo parts database as part of this battery family but are missing from a significant portion of aftermarket parts listings, which stops sourcing at E595. Repair depots processing E14 Gen 1 or E15 Gen 1 units do not need a separate battery SKU — the 01AV448 stock line covers these models without any P/N split.

Häufig gestellte Fragen
Q1: The battery removed from a ThinkPad E580 is printed with L17L3P51, but this listing is for 01AV448. Are these the same component?
A1: Yes. The L17-prefix P/Ns (L17L3P51, L17C3P51, L17M3P51, L17M3P52) and the 01AV-prefix P/Ns (01AV445, 01AV446, 01AV447, 01AV448) refer to the same physical battery. Lenovo uses two parallel numbering conventions for this component: the L17-prefix strings are internal component codes tied to cell vendor sourcing, while the 01AV-prefix strings are FRU (Field Replaceable Unit) numbers used in Lenovo’s service documentation and parts ordering system. Both sets cross-reference to the same 45Wh 3-cell Li-ion unit. A repair technician can order 01AV448 regardless of which P/N format appears on the removed battery label.
Q2: Some listings show 10.8V for batteries in this family. Is 10.8V a different battery from the 11.1V listed here?
A2: No. 10.8V and 11.1V are two conventions for expressing the same 3-cell Li-ion nominal voltage — 10.8V rounds to the lower end of the 3S Li-ion range, while 11.1V reflects a slightly higher nominal. Both figures appear in Lenovo’s own documentation for this P/N family and across the L17-prefix and 01AV-prefix P/Ns. The cells, connector, and BMS are identical regardless of which voltage figure is printed on the label. For procurement documentation, 11.1V is the more commonly cited figure; either is accepted by the ThinkPad E-series Embedded Controller without a compatibility warning.
Q3: Does this battery fit the ThinkPad E14 Gen 2 or E15 Gen 2?
A3: No. The ThinkPad E14 Gen 2 (Type 20TA, 20TB) and E15 Gen 2 (Type 20TD, 20TE) use a different battery family — the L19M3PF7 / L19C3PF5 / L19L3PF5 series at 11.1V but with a different connector and PCB layout. The 01AV448 is confirmed compatible with E14 Gen 1 (Type 20RA, 20RB) and E15 Gen 1 (Type 20RD, 20RE) only. A repair queue containing both Gen 1 and Gen 2 E14/E15 units requires separate battery SKUs; the batteries are not physically interchangeable even though the device chassis looks similar.
Q4: After installing 01AV448, the ThinkPad E490 shows “Battery not charging” in the system tray despite the AC adapter being connected. What is the likely cause?
A4: On the ThinkPad E490 and the broader E4xx/E5xx platform, this notification at first connection typically means the EC has not completed its charge authentication handshake with the new battery’s BMS. The most effective first step is a full power cycle: shut down the laptop, disconnect the adapter, hold the power button for 10 seconds, reconnect the adapter, then power on. This resets the EC’s charge state register and allows it to re-initiate the authentication sequence from a clean state. If the notification persists after two power cycles, update the BIOS via Lenovo’s support site — a firmware update resolves EC charge authentication failures on several E490 and E580 firmware revisions.
Q5: Can a repair depot place a replenishment order for 01AV448 alongside batteries for ThinkPad T-series or X-series models in the same purchase order?
A5: Yes. Mixed-SKU ordering is supported across Lenovo ThinkPad battery lines, so a depot managing inventory for E-series, T-series, and X-series repairs simultaneously can consolidate all battery needs into a single purchase order rather than raising separate orders by product line. Low MOQ applies to the total order, not per SKU. This is the standard replenishment path for multi-line service depots; submit your full SKU list across all ThinkPad lines to receive a consolidated volume pricing quote with a single lead time.
Q6: The ThinkPad E480 and E580 look similar and both use 01AV448 — is the battery physically identical in both chassis, or are there connector position differences to watch for?
A6: The battery is physically identical in both chassis. The ThinkPad E480 (14-inch) and E580 (15.6-inch) use different display panel sizes, but Lenovo standardised the battery bay dimensions and connector position across this generation — the same 45Wh 3-cell pack with the same connector orientation fits both without modification. The physical difference between the E480 and E580 battery bays is the chassis depth, not the battery slot itself. Repair technicians switching between E480 and E580 units in a mixed repair queue can use the same 01AV448 units interchangeably without any connector or orientation check.
