Michael Pepper, 67, from Glasgow, raped the woman on various occasions between 1986 and 2001.
He also hit her with a baseball bat and bottle, cut off her clothes, struck her with a knife, kicked her on the body and caused her to fall downstairs.
Pepper was also placed on the sex offenders register.
Jailing him at the High Court in Glasgow, judge Johanna Johnston QC told Pepper: "Your actions blighted this woman's life. You now accept your guilty, albeit at a late stage.
"However, this woman had to come to court and give evidence of a very private nature.
"This was a horrendous catalogue of offending."

After thunderstorms ended play prematurely on Friday, Poulter completed the remaining four holes of his second round in one under.
That gave him a six-under round of 66 and a halfway total of 14-under-par.
Veteran Spaniard Miguel Angel Jimenez parred the four holes he had to finish, adding a 73 to his opening 63, to leave him in a six-way share of second place.
Poulter, who birdied five of the first 11 holes on Friday, tweeted that evening: "Now that was a close call. On 14th green when lightning struck very close by."
After three-putting the 12th to drop a shot, the world number 40, aided by a strengthening wind, reached the par-five 13th green in two shots to set up a simple birdie.
And on Saturday he birdied his first hole of the day, the 15th, to boost his chances of a first European Tour victory in two years.
The 38-year-old is now 33-under-par for his last six rounds at the Colin Montgomerie-designed Maxx Royal course.
"I played exactly the same last week but didn't hole my putts," said Poulter, who finished joint sixth in the WGC-HSBC Champions last Sunday, the tournament which provided his last win in 2012.
Ryder Cup player Victor Dubuisson, who won the inaugural tournament last year, was 13 shots off the pace and one over.
The Frenchman, who played with a persistent nose bleed in round two on Friday, birdied the last for a round of 68.
World number four Sergio Garcia, the highest ranked player in the field, is two over after recording triple bogey sevens at different holes in both of his opening rounds.
The tournament is the third event of the European Tour's Race to Dubai Final Series, which culminates with the World Tour Championship in Dubai from 20 to 23 November.

A Scottish Canals team used Google Street View's Trekker camera backpack to capture attractions including the Crinan Canal and the Falkirk Wheel.
The camera is designed to allow easier access to narrow footpaths and bridges.
Neptune's Staircase on the Caledonian Canal and Stockingfield Bridge have also been captured.
The 4ft-high backpack, which weighs 40lbs, is fitted with a 15-angle-lens camera which takes 360 pictures every 2.5 seconds.
Scottish Canals' head of information and communication technologies Andrew McSherry said: "When Scotland's canals were first carved through the heart and highlands of the nation during the Industrial Revolution, they were considered at the cutting edge of engineering and design.
"It's been incredible to see every nook, cranny, and lock captured using this 21st Century equipment.
"The Trekker has been ideal for the narrower towpaths and bridges of Scotland's canals and allows us to show off some of the more hard-to-reach places along the canal network as well as the sights known the world over."
A Google spokesman said "We believe the world is better explored than explained.
"The Trekker enables you to travel to some of the most beautiful places on Earth, such as the Scottish canals, from the comfort of your own home."
