キーONで1週間放置、完全に放電したバッテリーを復活　Reviving a completely discharged battery with the ignition key on.

I left the key in the ON position while checking the power windows, and a week has passed since then. The battery is completely discharged. Is it possible to reuse the battery? Commentary ↓ Комментарий Translated by google I left the key in the ON position while checking the power windows, and a week has passed since then. The battery is completely dead, but is it possible to revive it? Я оставил ключ в положении «ВКЛ», проверяя стеклоподъемники, и с тех пор прошла неделя. Аккумулятор полностью разряжен, но можно ли его оживить?
