Question about 1993 Honda Civic 4 Door
What is the right sized battery because i brought one that might be too small and only starts once then needs recharging it does'nt even turn the starter motor over just clicks but when charged no worries
Almost any generic 12V automotive battery should work. Any automotive shop will be glad to make recommendations as to the battery capacity. As long as it's at least a passenger car style/size battery it should definitely last more than one "start".
I'm suspecting couple of things. First the battery is defective, or second, your car's charging system is shot. Hook up a volt meter across your battery and while someone is reving the engine above 4000RPM measure the charging voltage - it should be at least 14V, and about 13V at idle - if you don't get that, disconnect the battery after you start the engine(very carefully-don't short it out), and measure again across the charging connectors. If you don't get those voltages then you probably have a defective alternator, rectifier/regulator module, or both. Sometimes those modules are built right into the alternator. You might also have a bad or intermittent connection on one of the charging cables.
Only after you've verified the charging voltage do the next few checks:
Run the engine for at least 20 minutes, then turn it OFF.
What's the battery's voltage when the car is OFF? If it's only 12V or lower replace the battery? How low does the voltage drop during cranking? If it's less than 11V replace the battery.
