Not sure I follow your story.
Have you checked the output of the alternator while it is on the engine, and is it between 13 and 14 volts ? Does the battery lose power while the engine is running or after you turn the engine off ?
Is the alternator output normal but not reaching the battery ?

SOURCE: my honda civic start normaly, but after few minute start losing power

Several causes possible.
Carburattor or injection type?
Carburator >> auto choke faulty.
Carburator >> mixture very wrong adjusted
Drawning carburator (needle/floater)
Distributor weights cannot move (dirt/rust spring broken)
Very dirty airfilter, or clogged airfilter
Faulty ignition cap. Check contacts, especially middle one if oldfashioned and nonelectronical.
Ignition timing set incorrectly.
Fuel pump broken.
Fuel filter blocked almost.
Vacuum line damaged.
Exhaust internally clogged by loose plate (corrossion) (potato in tailpipe effect).
And very seldom, water or diesel.

And a list of a lot of other things.

SOURCE: Headlights causing battery drain while driving?

Though your car seems fine without using the headlights, you have a charging problem, and need to get a couple things checked out. First make sure your battery connections are clean and tight. Your alternator belt should also be checked to make sure it is serviceable and properly tightened too. Your alternator should be checked under load, and lastly, your battery too. Most auto parts stores, such as auto zone,will check your parts for free,so you should only be spending money on what is broken!

Something is draining the battery on my Honda civic, had 3 batteries all checks done any ideas ???

How I would address it...

* Shut down the car and pull the keys.
* Disconnect a battery ground, and connect ampere meter in the break.
* See how much is "drain" on the battery.
* Start pulling fuses, one-by-one, and see, when "drain" stops.
* When you find, which fuse stops the drain, you start digging, what is on that circuit.

Alternatively you may keep battery connectors on, but when you pull the fuse, connect ampere meter to both terminals to see what is the power consumption on that particular circuit.

PS. Another thought... It could be not a "drain when car is off", but rather "incorrect charging" while car is on. For example, if alternator produces too high or too low charge voltage, it may "kill" the battery, and it cannot hold "normal drain".

Why does my 1990 lose power and backfire

its probably your alternator i would start by testing that im pretty sure advanced can test it for you. also test your battery because when the alternator goes it will run off of your battery and drain it if that doesnt work out for you then your going to have to provide me with further symptoms

95 honda civic dx civic has good battery but still won't start sometimes its enought to start

If your car starts after you charge the battery overnight or with a jump start then the most likely problem is that your alternator is not charging the battery when the car is running. If you take it to an auto parts stores many of them will test your alternator (for free) to verify that is the problem.

If that isn't what is causing your problem you need to look for a short that is draining your battery and you would need a clamp on ampmeter to find that.

I have a 1991 Honda civic and the car will start but it will not

Have you changed the fuel filter? If your battery has power in it it is not the alternator. If the alternator is not charging the engine will become slugish as the battery power nears zero and the light will become dimmer and dimmer until they go out.

Car is losing power and speedometer not working

The alternator is dying...
It is not charging your battery. Don't use your headlights (big power drain) until you have the electrical checked.
AutoZone will analyze (free) w/o removing alternator (IN-CAR test)

Hope this helps, soon!

The battery light is on what does that mean

generally, the battery lite will come on due to a charging problem. 1st ck to make sure belt is on and tight. 2nd if you have volt meter, with vehicle running, ck voltage at battery terminals. should be over 13.5 volts, if not, verify there is 12 volt supply to large red wire at alternator. if there is voltage at alternator, but less than 13.5 across battery with it running, replace alternator
