Yes it can.
Especially if the battery has a low charge to begin with or it is an old battery.
Cold weather puts more strain on a battery than hot weather.
Check the battery and alternator. In hot weather we tend to use more juice from the battery because we run a stereo and the A/C.
No, that will have no effect on the battery.
sounds like the battery short-circuited.
your car ac will only blow hot air when there coolannt in the car is finished or the car is oveerheated.
Hot enought to kill you.
Depends on what you plan on doing with it. For power use while you're parked I suggest taking it directly from the battery (or running that to a splitter [for a separate trailer battery] - relay preferred - so that you don't kill the car battery overnight).
poss alternator fault
Well keep it simple, start with battery terminal connections,then go to ( I guess you are talking about Kia Sportages here ) start and fuel pump relays. Of course have battery tested.
Maybe, Hot weather kills batteries. In cold weather a battery that has a low state of charge can freeze and be damaged. Cold weather makes the power required to start the engine increase dramatically so a battery in a low state of charge cannot deliver the amps required to start the unit. When I lived in New Jersey I used a battery charger on the battery at low amps (cheap Sears charger) overnight in the fall to make sure the battery was fully charged at the onset of cold weather. Late in December I'd top it up again. At the same time make sure the alternator belt is tight enough. With engine off and cold grab the alternator fa/pulley and try to turn it. If it spins/slips on the belt without turning over the engine it's too loose and a full battery will become a low battery. This technique was easy and way cheaper than a stalled car call in a blizzard.
To hot wir a car you need jump leads. You need to connect the battery in your car to the battery in another car that is working using the jump leads. Then when you start up car #2 it will give car#1 enough electricity to start itself. From there, it will recharge itself as you drive.
Pouring hot water on a car battery may temporarily help dissolve some of the corrosion, but it is not a recommended method as it can potentially damage the battery. It's best to use a mixture of baking soda and water to clean corrosion from a car battery.
