Can I replace the lead acid battery in my car with a lithium battery?

My diesel engine is a 1990 unit, can I just replace the lead acid battery for a lithium battery

If your car is a 1990 model we would be very cautious about putting a lithium battery on it. The charging systems are designed for a lead acid battery and a lithium battery has a different requirement system. If fitted to a lead acid system this could result in problems with the charging system (i.e over or undercharging). Given the additional cost there may be no additional benefits of fitting a lithium battery.
