How to check compatibility
Verify your laptop model matches our compatibility list above. Check your current battery’s part number (usually printed on the battery) or look up your laptop’s model number in system settings or on the original packaging.
When to replace
Consider replacement when battery life drops below 50% of original capacity, charging takes significantly longer, or you notice physical damage like swelling. Most laptop batteries last 2-3 years with regular use.
