Joe Rankin-Costello opened his goal account for Charlton as they drew 1-1 with Championship leaders Coventry at The Valley.
The Sky Blues had the perfect start to the match with just over two minutes on the clock when Ellis Simms, who scored twice in the reverse fixture between the two clubs at the end of November, produced a clinical finish.
Former Everton striker Simms ended a six-match run without hitting the back of the net. He collected his ninth goal of the campaign as he converted first time from Milan van Ewijk's cross.
Charlton were the next to threaten and Sky Blues goalkeeper Carl Rushworth saved from Miles Leaburn after the striker ran on to Charlie Kelman's lofted pass.
Coventry striker Haji Wright sent a left-footed shot from the edge of the box wide of Thomas Kaminski's right-hand post with the hosts slow to close down the danger.
City's Joel Latibeaudiere cut in from the left flank to rifle over the crossbar in the 34th minute.
Referee Josh Smith waved away appeals for a penalty in the 36th minute when Kelman's shot struck the left arm of Latibeaudiere.
Coventry were content to slow play down with Van Ewijk booked for time-wasting after delaying taking a long throw in the 42nd minute.
Charlton had one final opening before the interval - once again Kelman produced a flick to send Luke Berry scampering into the penalty area. The attacking midfielder's decision to take an extra touch backfired as Latibeaudiere managed to nick the ball away.
Charlton ramped up the pressure at the start of the second half - but only after a double save from Kaminski to frustrate Wright and Jamie Allen in the 47th minute.
Kelman was close to getting on the end of Tyreece Campbell's excellent cross before the Addicks deservedly levelled in the 69th minute through Rankin-Costello.
The midfielder, hugely impressive in only his second league start of the season, tapped in from close range after Rushworth parried Kelman's attempt.
Soon after Kaminski produced an instinctive close-range save to frustrate Liam Kitching.
Charlton's number one came to the rescue again in the 81st minute to push away centre-back Kitching's 20-yard shot as the Sky Blues pushed to regain the lead.
Wright's last contribution before being replaced was to smash into the side-netting from Allen's pass.
