Have a Suzuki Baleno Kombi Bj 1998 petroler. It’s already longer time, but I start the car in the month 1x. and always sprung on The battery indicates over the multimeter 12.5 / 12.6 volts. petrol is enough in the car.The battery is now 4.5 years old. The car has always started up to now, now it doesn’t like any more. Who I turn on the ignition is also shown everything. But as soon as I want to start the car the car does not jump on. e is,possibly too old or too age-weak? Can it help me buy such a carbooster that uses the battery when starting.Thank you for your help
