Eish boss bateries have been sky rocketing for the past couple of years! Please, whatever you do, don't buy those cheap R300 knock-off's...go with willard or something. Bateries have an expectant life cycle of 5-6 years tops...I replaced mine 2 months ago after it left me stranded at the car wash...I coughed up R800 + my old weak Probe batery and the guy gave me a 5% discount...so its realy expensive! But do the right thing...buy a good batery!
