Question about Lenovo IdeaPad gaming 3 15ACH6 Battery issue.
Hello everyone!
I’m having an issue with my Lenovo Ideapad Gaming 3 15ACH6 (AMD Ryzen 5 5600H).
I’ve been using this laptop for over three years — mainly for daily work (9 to 5) and also for heavy gaming (about 2–3 hours per day). A couple of days ago, the laptop suddenly refused to power on unless the charger was plugged in. The moment I unplugged it, it would shut down immediately.
I opened the laptop to check the battery model, which is
L20D3PC2
, and tried to find a replacement. I bought another battery, but it turned out to be incompatible because the code was different (
L20C3PC2
). I also tried
L20M3PC2
, but both of them showed the same issue — the charging LED kept blinking, even when the laptop was turned off, and it blinked faster while charging.
Right now, I’m using a battery with code
L20C4PC0
, and fortunately it works — the blinking LED issue is gone. However, I’m still not sure whether it’s actually safe to use a battery with a different code than the original.
Does anyone know if this is okay, or should I stick strictly to the exact same model?
like-for-like parts are recommended, particularly for batteries. Using an incorrect battery may affect the power supply on the motherboard.
I purchased it from a local online shop:

Finding an authentic Lenovo battery in Indonesia is quite challenging, so I had to choose what’s nearby.
I also reached out to the Lenovo Indonesia Store in my area, but they informed me it would take around 4–6 months for an official replacement. That’s too long for my needs.
Yes, it is possible if the battery matches the precise technical requirements, not merely the same software version.
Lenovo frequently employs various battery part numbers for identical laptop models. The key factors are:
Consistent voltage
Identical connector and pin arrangement
Appropriate capacity range
Correct BMS (battery management system) interaction
The blinking LED you observed on other batteries typically indicates BMS incompatibility or firmware differences, not an inherently bad battery.
For the L20C4PC0 battery:
It charges normally
Doesn’t overheat
Displays accurate battery percentage in Windows
Maintains charge properly when disconnected
If these conditions are met, it is usually safe to proceed.
It remains advisable to:
Review Lenovo’s official parts catalog for the 15ACH6 model
Or verify with Lenovo support using your device type and serial number
Should it remain stable across several charge cycles, you should be confident.
