BAT­TER­IES MAKE OR BREAK THE MOD­ERN CAR

Torque (Singapore) - - POST BOX - CHRISTO­PHER CHOW 

The cur­rent age of motoring has brought a lot of mod­ern con­ve­niences, with plenty of cool elec­tronic fea­tures. How­ever, th­ese fea­tures – such as cam­eras, USB charg­ing, phone-link­ing to our au­dio sys­tem, GPS, etc – have also re­sulted in greater de­mands on our car bat­ter­ies. Th­ese, and the stop-start func­tion.

Said func­tion im­proves the car’s fuel con­sump­tion sig­nif­i­cantly by killing the en­gine. How­ever, this re­quires more cy­cles from our bat­ter­ies, and more driv­ers are com­plain­ing that the bat­tery has to be re­placed an­nu­ally in­stead of ev­ery two or three years. Even worse, some cars sim­ply died in the mid­dle of the road. With a new bat­tery cost­ing up to a few hun­dred dol­lars, the ques­tion is whether we are penny wise and pound fool­ish. The fuel sav­ings and en­vi­ron­men­tal ad­van­tages may be far out­weighed by the cost and in­con­ve­nience of fre­quent bat­tery changes.

Torque Thanks for shar­ing your in­ter­est­ing thoughts on car bat­ter­ies. Turn to pg 84 for our an­swers (by our me­chan­i­cal en­gi­neer Shree­jit Changaroth) to a few bat­tery-re­lated ques­tions, in­clud­ing stop-start sys­tems.
