Short answer: Yes. The vast majority of Lenovo laptops—ThinkPad, IdeaPad, Yoga, and Legion—use replaceable battery packs. Some are “user-replaceable” (one screw panel), others are “service-replaceable” (remove the bottom cover), and a few thin-and-light models require more careful disassembly due to adhesive and fragile ribbon cables. If your machine still meets your performance needs, a new battery is often the most cost-effective upgrade.

Which Lenovo models are easiest to replace?
| Series | Replaceability | Typical effort | Notes |
|---|---|---|---|
| ThinkPad T / X / P / E | Service-replaceable (internal); some older models had external packs | 10–30 minutes | Remove bottom cover; many ThinkPads allow “disable internal battery” in BIOS before opening. |
| Yoga | Service-replaceable (internal) | 20–40 minutes | 2-in-1 designs are thin; be gentle with flex/IO ribbons and hidden clips. |
| Legion | Service-replaceable (internal) | 15–35 minutes | Gaming chassis are roomy; mind high-power cabling and large battery footprint. |
| IdeaPad | Service-replaceable (internal); some older models removable | 15–35 minutes | Varies widely by sub-series; check screw types (Phillips/Torx) and clip positions. |
Costs and time
- Battery price: typically $45–$120 depending on capacity (Wh) and availability of the exact FRU.
- Labor (optional): $40–$120 depending on model complexity and local rates.
- Total: $85–$220. DIY on accessible models can stay under $80–$120 total.
How to identify the correct Lenovo battery (FRU/Type)
Lenovo uses FRU/ASM and Type codes (e.g., 01AV421, L18M3P71, 5B10XXXXXX) to ensure fit and connector orientation.
- Match by exact model: e.g., ThinkPad T480 20L5-xxxx, Yoga 7, Legion 5, etc.
- If accessible, read the label on the existing pack for FRU/Type and capacity in Wh.
- Confirm voltage/cell count: common are 11.1–11.4 V (3-cell) and 15.2–15.4 V (4-cell). Capacity in Wh defines runtime.
Tools & preparation
- Precision screwdriver set (Phillips #0/#00; Torx T5/T6 on some models)
- Plastic spudger & opening picks (avoid metal prying on the chassis)
- ESD precautions (ground yourself; avoid working on carpet)
- Small containers for screws; take photos during disassembly for reference
Universal replacement steps (internal battery)
- Power down the laptop. Unplug the charger. If available, disable the internal battery in BIOS.
- Remove the bottom cover: take out visible screws; release hidden clips around the perimeter with a plastic pick.
- Disconnect the old battery: gently lift the connector straight out; avoid pulling on wires.
- Unscrew the battery module and lift it out carefully.
- Install the new pack: seat it flat, fasten screws to spec, and reconnect the battery cable firmly.
- Reassemble the cover; ensure all clips and screws are secure.
- First charge cycle: boot into Windows, charge to 100% uninterrupted, then discharge to ~10–20% once and recharge to 100% to calibrate the gauge.
Safety, quality & longevity
- Choose quality: Look for CE/FCC/UKCA/UL where applicable and UN38.3/IEC 62133 test compliance.
- Protections: Battery packs should include over-current, over-voltage, short-circuit and temperature safeguards via the BMS.
- Avoid heat: High temperatures accelerate wear. Don’t store the laptop hot in a bag right after heavy use.
- Smart charging: If you’re mostly docked, enable Conservation Mode in Lenovo Vantage to cap charge ~55–60% (or 80%) and reduce long-term wear.
- Recycle: Dispose of the old pack through certified e-waste channels—never in household trash.
Common questions
Can every Lenovo battery be replaced?
Practically all modern Lenovo laptops have replaceable packs, but difficulty varies. Some ultra-thin models use more clips/adhesive and require extra care. If in doubt, check a service manual for your exact model.
Will a higher-capacity option fit?
Sometimes—if Lenovo offered multiple capacities for the same chassis. Match supported FRU numbers; don’t force a pack that doesn’t line up with standoffs or the connector.
My laptop shows “plugged in, not charging.” Is the battery bad?
Not always. First rule out charge limits in Lenovo Vantage (Conservation Mode), cable/adapter issues, and BIOS/EC updates. If health is poor or the pack is swollen, replace it.
Do I need a new charger too?
Only if your adapter is faulty or under-powered for your model. ThinkPads and Legions with dGPUs often require higher-wattage adapters for best performance.
