Got a 1998 Toyota Camry that has an empty battery and am wondering what the best course of action is. Why is it empty? Is it empty because the battery is old and dying and won't hold capacity? Or is it empty because you yesterday forgot the lights on? The correct course of action depends on the reason for it being empty. If the battery is good but you just ...

If the battery is completely flat, then it will have been severely degraded in capacity. Lead acid batteries don’t hold their full charge after going completely flat, so it would be best to replace the battery and make sure this doesn’t happen again. However if you want to try to charge it, it will be less stressful for the battery to be slowly charged by a ...

A better solution is to fix these two problems and correct a few other common faults. Use a voltmeter or a test light to confirm if the switch is receiving and outputing 12 volt power. Then go to the bulb and see if it is receiving power. Even with power, the bulb would not work if the ground side is poor, or the bulb is open circuit. Also, look for ...

You have it backwards, battery insulators are used to protect batteries from excess engine heat rather than protect them from cold, as extreme heat is worse for batteries than cold. Car batteries have no heat source, so an insulating blanket is only going to slow heat loss, a car battery sitting overnight will still reach ambient air temperature.

The "classic" warning light was connected between battery positive and the alternator output. This would then exhibit various states of illumination, which with experience, would tell one what was wrong without having to do all the tests stated in the workshop manual. So, if the light was on solid bright then the alternator was not charging and ...

The short of this is yes, you MAY have damaged your rear brakes. The only way to tell for sure is to have them inspected by a mechanic (or if you know what you are doing, inspect them yourself) and determine if there has been damage, what is the extent of it, and what (if anything) needs to be fixed. In some cases the damage is just premature wear of the ...

Modern fuel injection ,electronic ignition ,should start easily down to about 0 F (outside). So I would not bother with insulation. Insulation will slow cooling but overnight in wind it will cool to about the same temperature ;so, no real difference in battery temperature / voltage. Long ago ,with carburetor and points ignition, I took the battery out and ...

and there is more: These days some cars will have an extra battery if they're running stupidly powerful stereos, winches or other high power devices without draining the starter battery. These will generally be “deep cycle” batteries, capable of surviving more drain and lower voltages than a typical starter battery. Mercedes (I don't know about any others) ...

the 1 at the engine is for starting. the other (called deep cycle), is for supporting all the electronic components that draw a lot of current even if the engine is not running, and otherwise drains the starter battery faster. the starter has more thinner plates, and is more effective for it purpose. the other has less, thicker, and does better for keeping ...
