McLaren suffered two problems on Tuesday, with Stoffel Vandoorne not being able to even get back to the team’s garage under his own power.

Red Bull then lost some track time as Max Verstappen brought out the red flag. All this problems were as a result of the battery problems.

“The issues that we’ve had I don’t think have any relationship to the installation of the battery at all,” said Renault chief technical officer Bob Bell- “We haven’t had any problem, but what we do ahead of Melbourne is that we try and shakedown all of the battery systems to make sure all of the stock that are going racing are in good shape. That’s why we test them here. We revolve them around the customer teams and ourselves to make sure they are all tested ahead of Melbourne. So it’s not unusual to find issues. Those problems could have affected any of the three teams, so of course it’s an issue for us but the reason we do this testing of those components before going to Melbourne is to find the ones that have got problems,” he said. “It’s the right thing to do, we have found some that are not fit for purpose and that’s great. By regulation, each driver gets two units per year, so that’s what they are designed to do. That’s a pretty heavy duty cycle for them, and the importance of making sure they are completely fault-free is critical, which is why we test them ahead of Melbourne.”
