What Is the Lenovo 01AV412 Battery?
The Lenovo 01AV412 is a 45Wh lithium-ion replacement battery built for selected ThinkPad laptops. It is rated at 11.1V and uses a 3-cell design, making it a balanced option for users who want stable day-to-day battery life without adding unnecessary bulk.
For many laptop users, battery replacement becomes necessary long before the rest of the machine is outdated. If your ThinkPad still performs well for office work, web browsing, remote meetings, business applications, schoolwork, or light technical tasks, replacing the battery can extend the useful life of the laptop at a much lower cost than buying a new one.
Who Should Consider This Battery?
This battery is a good fit for buyers whose Lenovo laptop is still functioning well but has lost battery endurance over time. It is especially useful for:
- Students who need a dependable laptop for classes and study sessions
- Office users working between meetings, desks, and home
- Remote workers who want reliable unplugged performance
- Repair shops and technicians restoring ThinkPad laptops
- Business users keeping older Lenovo laptops in service
If your laptop still boots quickly, handles your normal programs, and meets your daily needs, weak battery life does not mean the entire machine needs to be replaced.
Compatible Lenovo Battery Part Numbers
Many buyers identify the correct battery by checking the label on the original pack. This replacement battery is compatible with part numbers such as:
- Lenovo 01AV411
- Lenovo 01AV412
- Lenovo 01AV413
- Lenovo SB10K97568
- Lenovo SB10K97569
- Lenovo SB10K97570
If your old battery carries one of these part numbers, that is a strong sign you are looking at the correct replacement family. Even so, it is always wise to compare both the battery number and the physical connector layout before placing an order.
Compatible Lenovo Laptop Models
This battery is commonly associated with selected Lenovo ThinkPad models, including:
- Lenovo ThinkPad E470
- Lenovo ThinkPad E470 (20H1 / 20H2)
- Lenovo ThinkPad E475
- Lenovo ThinkPad E475 (20H4)
Because laptop batteries can vary even between similar-looking models, buyers should not rely only on the laptop series name. The safest method is to confirm the model number, original battery part number, and physical shape.
Important Buying Note: Check the Physical Shape
One of the most important details when ordering a replacement Lenovo battery is physical compatibility. Even if the part number looks close, the connector position, screw holes, cable direction, and overall battery shape must match your original battery.
That is why it is smart to check:
- Your exact laptop model
- Your original battery part number
- The battery shape and connector layout
This extra step can help avoid ordering the wrong part and saves time during installation.

Common Signs Your Lenovo Battery Needs Replacement
Not sure whether your current battery is the problem? Here are some of the most common warning signs:
- The laptop battery drains much faster than it used to
- The battery percentage drops suddenly
- The laptop shuts down before the charge reaches 0%
- The system only works properly when plugged in
- Battery runtime has become too short for practical daily use
- The current battery is several years old
These symptoms usually point to battery wear. Over time, all lithium-ion batteries lose capacity due to age, charging cycles, heat, and normal use.
Why Replacing the Battery Can Be a Better Choice Than Replacing the Laptop
Many Lenovo ThinkPad laptops remain highly usable long after their original battery has degraded. Business-class ThinkPads are known for solid keyboards, durable construction, and practical performance. If the machine still meets your needs, a battery replacement is often the smarter investment.
Instead of spending far more on a new laptop, you can restore mobile usability with the right replacement battery and continue using a machine you already know and trust.
Built-In Safety Matters
A good replacement battery should do more than simply fit. It should also provide reliable electrical protection during charging and normal use. This battery is built with safety protections designed to help guard against:
- Overcharge
- Over-discharge
- Short circuit
- Overcurrent
- Temperature-related risk
These protections are important for everyday reliability, especially for laptops used at work, in classrooms, or during travel.
Use Cases: Work, Study, and Travel
This replacement battery is a good choice for users who need dependable power throughout the day. Common real-world use cases include:
- Work: email, spreadsheets, documents, meetings, browser-based tools
- Study: note-taking, online classes, research, homework
- Travel: airport use, train rides, mobile work sessions, backup power away from outlets
For these types of tasks, restoring normal battery life can make a huge difference in convenience and productivity.
Installation Tips Before You Buy
Before purchasing a replacement Lenovo battery, take a minute to inspect your original part. Remove the bottom cover if needed and compare the old battery label with the product image and listed part numbers. This small step can prevent compatibility mistakes.
You should also keep in mind that newly installed batteries often perform best after a few normal charge and discharge cycles. That helps the battery settle into regular usage patterns and gives you a more realistic sense of runtime.
