Alpha Centauri B is a star similar to our Sun and is estimated to have a lifespan of around 6-7 billion years. It is currently around 6 billion years old, so it still has several billion years left before it exhausts its nuclear fuel and reaches the end of its life cycle.
Alpha Centauri is a binary star system, andpossibly a triple star system.
Alpha Centauri A is a G2V star similar to our own Sun.
Alpha Centauri B is a K1V star
Alpha Centauri C (Proxima Centauri) is a M5 star.
A will end it's life, similar to our Sun, by first expanding as a red giant and them shed it's our layers before becoming a white dwarf.
B will end it's life the same as above.
C will end it's life, eventually, after about four trillion years, by just fading away.
However, there is a possible chance that if B becomes a white dwarf before A, then it might be able to accrete mass from A and become a nova.
Dating the demise of a star is very difficult. We know that Alpha Centauri A is very similar to our own Sun - albeit a bit larger - and they formed around the same time, so A will probably end it's life a little earlier than our own Sun (Approximately 4 billion years time). Alpha Centauri B is a much cooler star than A, so will probably out live it.
However, because they are a binary pair and their close approach to each other (11 AU) it is possible that when A becomes a white dwarf, it may be able to accrete hydrogen off of B to produce a nova explosion. However, because of the highly eccentric orbit, this seems unlikely.
In that case B will continue as a orange dwarf for billions more years.

What does the double star Alpha Centauri A and Alpha Centauri B form with Proxima Centauri?
Alpha Centauri A and Alpha Centauri B form a binary star system, while Proxima Centauri is a red dwarf star that is located further away from the binary system. Together, these three stars make up the Alpha Centauri system, which is the closest star system to the Sun.
What is the closest system to your sun?
The closest star system to our Sun is Alpha Centauri, which consists of three stars: Alpha Centauri A, Alpha Centauri B, and Proxima Centauri. Proxima Centauri is the closest to the Sun at a distance of about 4.24 light-years.
What is the difference between Alpha Centauri A and Alpha Centauri B?
Alpha Centauri A is a main-sequence star slightly larger and brighter than the Sun, while Alpha Centauri B is a smaller and cooler main-sequence star. Both stars are part of the Alpha Centauri star system and are in close proximity to each other, orbiting around a common center of mass.
What is the nearest star to the celestial equator?

Which star is actually composed of 3 stars forming a triple star system?
Polaris (the North star - Alpha Ursae Minoris) is a triple star system, but appears to us as a single star. Alpha Centauri is also another triple star system. And there are many more.
What are the 3 nearest stars to OUR sun?
The three nearest stars to our Sun are Proxima Centauri, Alpha Centauri A, and Alpha Centauri B. They are part of the Alpha Centauri star system, located about 4.37 light years away from us.
Virgo is the nearest star system to ours?
Alpha Centauri is the nearest star system. Its a binary star system of Alpha Centauri A and Alpha Centauri B. If someone asks you what is the nearest star ? then the answer will be "proxima centauri" in my opinion. nearest star: proxima centauri nearest star system: Alpha centauri A and B. Some people believe that its a triple star system of Prixma, Alpha A and Alpha B. centauri.
Which star is bigger the alpha centauri or the sun?
