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) matches MSI-BTY-L78left-75.24Wh. For MSI laptops, you can also check compatibility through the MSI Dragon Center software.
When to replace
Replace your battery when it no longer holds sufficient charge for your needs, shows physical damage, or reaches 2-3 years of regular use. Gaming laptops typically experience faster battery degradation due to high power demands.

Power off and unplug your laptop. Remove the bottom panel (usually requires Phillips screwdriver). Disconnect the old battery connector, remove mounting screws, and install the new battery. Reverse the process to reassemble. Always refer to your laptop’s service manual for specific instructions.
Usage & care tips
Avoid extreme temperatures (ideal range 15-25°C). Don’t leave your laptop plugged in constantly. Calibrate your battery monthly by fully discharging then charging. Store at 40-60% charge if not using for extended periods. Keep connectors clean and free from dust.
Safety & recycling in AU/NZ
Never attempt to open or modify the battery. Dispose of old batteries at authorised recycling centres. In Australia, check with your local council for battery recycling programs. In New Zealand, use designated battery recycling drop-off points. Never dispose of lithium batteries in household waste.
