Freddie Ladapo’s second-half equaliser ensured that Nathan Jones picked up his first point since being appointed Charlton manager.
However, a 1-1 draw against Lincoln at The Valley stretched the relegation-threatened Addicks’ winless run in Sky Bet League One to 14 matches.
The first half lacked quality until Reeco Hackett struck in the 37th minute. The Imps winger was first to latch on to George Dobson’s clearing header and drove a low finish past Harry Isted at his near post.
Ted Bishop put an early effort from a Lasse Sorensen shot wide, while Charlton struggled to fashion openings in a scrappy opening.
Tyreeq Bakinson produced a tame effort from Daniel Kanu’s lay-off inside the penalty area.
Lincoln’s Danny Mandroiu saw a 25-yard attempt crash back off the right upright in the 67th minute after Hackett nudged a short free-kick into his path.
Substitute Ladapo, on loan from Ipswich, had only been on the pitch for a couple of minutes when he levelled, striking the ball beyond Lukas Jensen from the edge of the box.
Lincoln keeper Jensen made a vital late stop to deny Tayo Edun as the visitors extended their unbeaten run to six matches, with this their fourth draw in that sequence.
