How to check compatibility
Locate your laptop model number on the bottom casing or battery compartment. Cross-reference with our compatibility tables above. For Sony Vaio models, the battery part number is typically printed on the original battery.
When to replace
Replace your battery when runtime drops below 50% of original capacity, when swelling occurs, or if the laptop fails to operate on battery power alone. Most laptop batteries last 2-3 years with regular use.
Installation guide (overview)
Power off your laptop and disconnect the AC adapter. Remove the old battery by releasing the locking mechanism. Align the new battery with the connectors and secure it in place. Allow the battery to charge fully before first use.
Usage & care tips
Store batteries at room temperature (15-25°C). Avoid complete discharges – recharge when battery reaches 20-30%. Calibrate your battery monthly by fully charging then discharging. Keep contacts clean and dry.
Safety & recycling in AU/NZ
In Australia and New Zealand, lithium-ion batteries must be recycled at authorised collection centres. Never dispose of batteries in household waste. Check with your local council for battery recycling programmes. Damaged or swollen batteries should be handled with care and taken to specialised recycling facilities.
