A covered bay keeps the worst heat off the battery, so cars in The Views often get a little more life than cars parked in the open. They still fail, for a different reason. Many residents work nearby in Dubai Internet City or Media City, and a commute that short never fully recharges the battery.
Newer cars add to it. Keyless entry, alarm, tracker and dash cam all draw a small current while the car is parked. Over a long weekend that is nothing. Over three weeks of leave it can empty a battery that was already half charged from short trips.
