RX 400h starter battery dead, bridge easily possible ?

Hello Lexus driver, should drive the RX 400h of a good friend out of the garage. Since she emigrated, she could not move the Lexus of course either… Unfortunately the battery seems to be so dead (8 months of service life) that even the interior lighting is no longer possible. Is the bridge easily possible, in relation to hybrid technology etc. ? Or does this have nothing to do with it ? Have never had anything to do with such technology. Are there any faults to expect (displacement lock) etc.) ?? Or excitement on it, start and everything is tacko ? With greeting from Lake Constance !!
