First, if you're in any vehicle and use /mycarstats to get info of VehicleInfo[vehicleid][carBatteryL] and VehicleInfo[vehicleid][carEngineL], they are 0 before i have set them to 100

PHP Code:

public OnVehicleHealthChange(vehicleid, Float:vehicle_newhealth, Float:vehicle_oldhealth)
{
  new
      myArray[92];
  if(vehicle_newhealth < vehicle_oldhealth)
  {
    foreach(Player, u)
    {
      //lasthealth = vehicle_health_loss - floatround(vehicle_newhealth);
      if(IsPlayerInVehicle(u, vehicleid) && GetPlayerState(u) == PLAYER_STATE_DRIVER)
      {
        if(vehicle_newhealth > 550 && vehicle_newhealth < 649)
        {
            format(myArray, sizeof(myArray), "damage @ vehicleID:%i, newhealth:%.3f, oldhealth:%.3f, difference:%.3f, BatteryL: %d EngineL:%d", vehicleid, vehicle_newhealth, vehicle_oldhealth, (vehicle_oldhealth - vehicle_newhealth), VehicleInfo[vehicleid][carBatteryL], VehicleInfo[vehicleid][carEngineL]);
            SendClientMessage(u, 0xFFFFFFFF, myArray);
            VehicleInfo[vehicleid][carBatteryL] -= ((vehicle_health_loss - vehicle_newhealth)/125.0);
            VehicleInfo[vehicleid][carEngineL] -= ((vehicle_health_loss - vehicle_newhealth)/150.0);
        }
        else if(vehicle_newhealth > 390 && vehicle_newhealth < 549)
        {
            format(myArray, sizeof(myArray), "damage @ vehicleID:%i, newhealth:%.3f, oldhealth:%.3f, difference:%.3f, BatteryL: %d EngineL:%d", vehicleid, vehicle_newhealth, vehicle_oldhealth, (vehicle_oldhealth - vehicle_newhealth), VehicleInfo[vehicleid][carBatteryL], VehicleInfo[vehicleid][carEngineL]);
            SendClientMessage(u, 0xFFFFFFFF, myArray);
              VehicleInfo[vehicleid][carBatteryL] -= ((vehicle_health_loss - vehicle_newhealth)/100.0);
               VehicleInfo[vehicleid][carEngineL] -= ((vehicle_health_loss - vehicle_newhealth)/125.0);
        }
        else if(vehicle_newhealth > 250 && vehicle_newhealth < 389)
        {
            format(myArray, sizeof(myArray), "damage @ vehicleID:%i, newhealth:%.3f, oldhealth:%.3f, difference:%.3f, BatteryL: %d EngineL:%d", vehicleid, vehicle_newhealth, vehicle_oldhealth, (vehicle_oldhealth - vehicle_newhealth), VehicleInfo[vehicleid][carBatteryL], VehicleInfo[vehicleid][carEngineL]);
            SendClientMessage(u, 0xFFFFFFFF, myArray);
            VehicleInfo[vehicleid][carBatteryL] -= ((vehicle_health_loss - vehicle_newhealth)/75.0);
            VehicleInfo[vehicleid][carEngineL] -= ((vehicle_health_loss - vehicle_newhealth)/100.0);
            VehicleInfo[vehicleid][carBroken] = 1;
        }
        break;
      }
    }
  }
  return true;
}

Try to set the random values when gamemode is connected or when the car is spawned for example:

Code:

public OnGameModeInit()
{
	for(new i;i < MAX_VEHICLEs;i++)
	{
		VehicleInfo[vehicleid][BatteryLife] = random(500);
		VehicleInfo[vehicleid][EngineLife] = random(500);
	}
	return 1;
}
