Product Description

The L17L3PE0 is a 3-cell, 51.5Wh Li-ion replacement battery covering two active Lenovo Yoga 730 15-inch platforms — the 730-15IKB (Type 81CU, Intel 8th Gen) and the 730-15IWL (Type 81JS, Intel Whiskey Lake). Both are convertible 2-in-1 devices with a strong presence in corporate and education device fleets; repair volumes for this battery are distributed across two separate type codes that many parts listings treat as distinct sourcing lines, when in practice a single SKU covers both.

The 730-15IKB and 730-15IWL share the same 51.5Wh battery specification, connector position, and physical form factor despite launching in different years and carrying different CPU generations. A depot stocking L17L3PE0 holds complete battery coverage for both platforms simultaneously, with no need to maintain separate bin locations or purchase orders by type code.

For procurement managers running asset refresh programmes that include a mix of 81CU and 81JS units, this dual-platform coverage eliminates the most common sourcing friction point for this Yoga line: the false assumption that Intel Core i5/i7 8th Gen and Whiskey Lake variants require separately sourced batteries. One replenishment order covers the full installed base regardless of which CPU generation is represented in the device pool.

Features & Advantages

✅ 🔋 3-Cell Li-ion Architecture at OEM-Specified 51.5Wh

This battery uses Grade A 3-cell Li-ion cells in a 3ICP6/54/90 or 3ICP6/55/90 configuration, delivering 51.5Wh at 11.25V nominal — the capacity and voltage Lenovo specifies for both 15-inch Yoga 730 platform types (81CU and 81JS). At 500 rated charge cycles, a deployed fleet unit reaching end of battery life at a typical corporate 3-year refresh interval will have consumed roughly 60–70% of this cycle budget, leaving meaningful reserve capacity and reducing the likelihood of early-failure claims against the replacement unit.

✅ 🔗 Dual Type-Code Coverage from a Single Stock Line

L17L3PE0 and L17C3PE0 are electrically and physically interchangeable within both the Yoga 730-15IKB (81CU) and Yoga 730-15IWL (81JS) chassis. The nominal voltage label differs between these two P/Ns — 11.25V on L17L3PE0, 11.4V on some L17C3PE0 listings — but this reflects a labeling convention difference rather than a circuit specification change; the cells and BMS circuitry are identical. Trade buyers sourcing by printed P/N from removed batteries can order either P/N with full confidence in fit and function across the entire 730-15 15.6-inch family.

✅ ⚙️ Yoga 730 EC Behaviour and BMS Protection Scope

On Yoga 730 15-inch platforms, the Embedded Controller polls the battery’s smart chip immediately after power-on and at each wake-from-sleep event — a failed poll triggers a “Consider replacing your battery” warning in Windows power settings that can appear even on a physically functional replacement if the connector is not fully seated. The BMS on this unit handles over-discharge cutoff as the primary protective action, since deep-discharge is the most common failure mode on convertible platforms used in tablet mode with irregular charge habits. Short-circuit interrupt and overcharge protection operate as secondary control layers above the cell-level chemistry thresholds.

✅ 📦 Purchase Order Consolidation Across Both Yoga 730-15 Generations

A service contract or warranty repair pool covering mixed 81CU and 81JS device populations requires no P/N split at the purchase order stage — L17L3PE0 resolves both type codes from a single line item. This simplifies the PO drafting and approval workflow for procurement teams managing multi-generational Lenovo fleets: one description, one part number, one receiving inspection point. Wholesale trade orders are available from stock at low MOQ, with mixed-SKU ordering supported for depots combining this battery with other Lenovo lines.

✅ 🔍 Connector Variant Awareness for High-Volume Repair Queues

Multiple production runs of the L17L3PE0 and L17C3PE0 have introduced minor connector socket geometry differences — a documented characteristic of this P/N family where the protruding socket element on some replacement units does not fully seat in the 81JS chassis connector without minor guide adjustment. Repair depots processing high volumes of Yoga 730-15IWL units should verify connector seating on the first unit of a new batch before proceeding through a larger repair run. This is not a compatibility failure; it is a batch-level quality check relevant to service depot throughput planning.

FAQ

Q1: Some sources list L17L3PE0 at 11.25V and others list L17C3PE0 at 11.4V — are these actually the same battery?

A1: The voltage difference is a labeling convention, not a specification split. L17L3PE0 and L17C3PE0 share the same 3-cell Li-ion cell configuration (3ICP6/54/90 or 3ICP6/55/90), the same 51.5Wh energy rating, and the same physical connector. The 11.25V vs 11.4V discrepancy reflects how different production batches report nominal cell voltage — one convention rounds the 3S Li-ion nominal downward, the other rounds it upward. Both P/Ns are accepted interchangeably by the Yoga 730-15IKB and 730-15IWL embedded controller and will charge and discharge identically in use.

Q2: Does L17L3PE0 fit the Yoga 730-15IBK, which appears on some compatibility lists alongside the 15IKB?

A2: The Yoga 730-15IBK designation appears in several third-party parts listings as a compatible model for this battery family. The 730-15IBK and 730-15IKB are effectively the same hardware line — the “IBK” notation is an alternative suffix used in some regional market documentation for the Type 81CU platform. If the device type code on the base label reads 81CU, the L17L3PE0 applies regardless of which suffix appears in the product name.

Q3: Does this battery cover the Yoga 730-13IKB or Yoga 730-13IWL 13-inch models?

A3: No. The 13-inch Yoga 730 series uses a completely different battery — the L16M4PB1 / L16L4PB1 / L16C4PB1 family at 7.68V, which is a 2-cell pack at a lower voltage and lower capacity. L17L3PE0 is specific to the 15.6-inch 730 platform only (Type Codes 81CU and 81JS). Orders placed for 13-inch units using this P/N will result in a non-fitting part. If your repair queue includes both 13-inch and 15-inch Yoga 730 units, these must be sourced as separate line items.

Q4: After installing L17L3PE0 in a Yoga 730-15IWL, Windows shows full battery percentage but the unit runs unusually hot. Is this a battery issue?

A4: Thermal behaviour immediately after a battery replacement on the Yoga 730-15IWL is typically unrelated to the battery itself. The platform’s fan and thermal management are controlled by the EC firmware, which recalibrates load-based thermal thresholds over the first few charge cycles following a battery swap. If elevated temperature persists beyond 2–3 full charge/discharge cycles, check that the fan duct was not disturbed during battery installation — the 730-15IWL fan outlet sits adjacent to the battery bay, and partial obstruction during reassembly is the most common cause of post-replacement thermal anomalies on this chassis.

Q5: Can I place a sample order for L17L3PE0 before committing to a volume purchase?

A5: Sample units are available prior to volume commitment. This is the standard path for repair depots and IT asset managers qualifying a new battery supplier — sample units allow your technicians to verify connector fit across your specific Yoga 730-15IKB and 730-15IWL device stock, confirm EC recognition on your firmware versions, and run a cycle test before placing a standing order. Contact us with your device type codes and current fleet size to initiate a sample request with relevant lead time.

Q6: The L17L3PE0 listing on some platforms shows a different mAh rating — 4520mAh vs 4587mAh. Which is correct, and does it matter for procurement?

A6: Both figures appear in trade listings and reflect minor variation in how capacity is measured across production batches. The authoritative specification is the Wh rating of 51.5Wh, which is consistent across all verified sources for this P/N. The mAh figure is a derived value that fluctuates slightly depending on the exact nominal voltage the manufacturer uses in its calculation (51.5Wh ÷ 11.25V ≈ 4578mAh; ÷ 11.4V ≈ 4518mAh). For procurement purposes, match on P/N and Wh rating — do not reject a batch on the basis of mAh variance alone if the Wh and P/N are correct.
