Questions
Buying a used Seal 82.5 kWh pack
Still unsure which pack is right? A specialist can check fitment with you.
Talk to a specialistGo by the trim. Design (230 kW, rear-wheel drive) and Excellence (390 kW, all-wheel drive) cars have the 82.5 kWh pack. The Seal Comfort, a 170 kW rear-wheel drive car sold in the EU from 2025, has the 61.4 kWh pack. The Seal U and the Sealion 7 are different cars. Send us a photo of the label and we will check.
The one BYD Seal 82.5 kWh pack with a fixed price on ReBattery is listed at €2,228 right now. The price depends on condition and measured health, and some sellers take offers instead. Fitting by an EV garage costs extra.
Not confirmed. The Sealion 7 is a different car, and no source says its pack is the same part as the Seal's. Check the label on the pack and the car it came from.
Sources disagree. A 2026 teardown of a newer Blade pack, built for China, found structural adhesive throughout that made it hard to take apart. A 2026 engineering review describes BYD's design as still serviceable. Ask a BYD specialist before you buy a pack to repair.
You have 7–14 business days to inspect it. Raise it with evidence and the seller is not paid until it is resolved.
