Verstappen was also the victim of another Renault power unit battery failure, which occurred later in the day when his Red Bull stopped in turn one.
Ferrari only set their best time on Wednesday on the soft tyres - three "steps" below the hypersofts - but the sense that F1 could be braced for a three-way fight in 2018 between Mercedes, Red Bull and the Scuderia is gathering strength in the paddock. Bottas came out firing, quickly matching the pace of his team-mate on the hypersofts and pushing the Silver Arrows past 100 laps on the day. There are just two days of testing left - and only one day in the car for Alonso - but the two-time world champion is not concerned.
While the works team enjoyed a productive Tuesday, its new customer McLaren did not fare as well. Hamilton was 0.353s behind Ricciardo on the ultra-soft tyre, though Pirelli expects the teams to dip into the high 1:17s by the end of this test.
McLaren has switched to Renault in 2018 after terminating its difficult three-year relationship with Honda.
Asked if he will be ready for Australia with just one more day in the car during testing, Alonso replied: "Yeah, I think so".
"It's been a good day", Hamilton said.
Ferrari would have likely completed more mileage but had to change its driver line-up at late notice due to Raikkonen feeling unwell.
Alonso did get back out for the final few minutes of testing on Wednesday and Boullier believes McLaren's early teething problems are to be expected.
During a morning session marked by a number of quick lap times, Ricciardo set the pace with a 1m18.047s to register the fastest lap on the current circuit layout. "If they are, we can definitely find that quite soon and don't let them win five in a row!" Hamilton's teammate, Valtteri Bottas, finished with the third-fastest time.
Kimi Raikkonen and Lance Stroll completed the day's top ten. The American team had hoped to complete a full race simulation in the afternoon before detecting the issue, restricting Romain Grosjean to 75 laps overall.
However, long runs on the medium tyre helped the French manufacturer break for lunch with a reasonable tally of 48 laps.
Renault has blamed faulty batteries for electrical problems suffered in testing by McLaren and Red Bull, both teams who use its engines. So I remember from Monaco before Canada going to Paul Ricard, doing maybe a 20-lap day and there was no coverage. The 24-year-old Colombian driver was the team's development driver last season.
