You might have loose connections or low cells on your battery. Check the cells on the battery and if they are low fill them with distilled water only. Also make sure your alternator is giving the battery a good charge.
distilled water
bad cells usally the water in the battery gets low damaging the cell
You can refill you ink cardridge by taking it to various stores that refill cartridges. Wal-Greens offers to refill ink cartridges for a reasonably low price.
You can refill your air conditioning system from the low pressure port on the air conditioner compressor. The low pressure port will be labeled as such.
Your car battery is a "lead-acid" battery. I'm not sure where you might haveheard about Epsom salt, but that's an easy and effective way to completelyruin the battery for good. If the battery is not sealed and you have accessto the cells, then when a cell gets low ... meaning the tops of the plates aresticking out above the surface of the liquid ... then you add distilled waterONLY to bring it up just over the top of the plates, and nothing else.
The meter shows low because when the batt. is all charged up the currant is very low because the batt. does not need to draw any more currant. When the batt. is low the batt. draws currant becaus the cells in the batt. need currant to charge.
A battery is simply two or more cells connected together.
Just replace the battery if you suspect it is low.
Check the specific gravity of each of the cells in the battery. If one is low then put a rapid charge on the battery. If the cell comes back to normal then wait about 10 hours and check the specific gravity again. If the reading is low again you have a cell that is shorting out inside the battery case. Time to think about buying a new one.
Either wet or dry cells are used to make a battery.
Its old and the electrolyte level must've been low in turn causing the lead to fall off the plates in the cells which caused them to no longer work.
