Just found this very old case. After this and thanks to all, honda hybrid battery has 8 years warranty.

If we replaced after 8 years, does it has another 8 years on the new battery or only 6 months??

No one can answer this question of replacement battery warranty.

Just an update, after 320000km ,my civic hybrid battery Kong. Brought in honda kk. Total rm6600 without inverter. Changed inverter last year. Ima battery warranty 5 years or 140k km.
