Check it out
I know somepeople might argue with me about it but you might want to check the water level in your battery, Most places will tell you its Maintenence free, but there is no such thing. Ever wonder why there are two caps on the battery where you can conveiniently place a flat tip screw driver under. Just flip them off, be careful to not get the water on you , Use Only Distilled water , or Ionized Water when you do this, use a funnel or paper cup and pour slowly. you know its low if you see the water level below the top of the slots on the walls of the 3 tubes under the two caps, it should be filled, to the top of the groove.
The battery relies on a chemical reaction between the water and acid, to charge properly, if there is no water you get a week charge, and we dont have battery meters so you need to check it once a year.
doing this on all of our cars will help us start our cars faster, get a better spark and help the wear and tear on our batteries,if you drive to long with out water your battery might not ever charge.
Everyone should check this now. especialy if your battery is OEM, and Half Empty like mine was, Mine is a 99 too.
