i have recently bought a 90 crx and i have had a problem with the battery
it wont keep its charge...

like each time i would start it it would be keinda slow cranking
then last night it just wouldnt
so i bump started it and it was fine
but now it has noooo juice

but get this after running around town i come back and turn off the car
then i try top start it and it starts fine
the next day i come out and not juice....and the lights werent left on
WTF?

so its on the charger right now

if theres juice after running it the alternator should be good right?
oh and the battery makes noise like kind of a steam noise

do i need a new battery or just a clue

thanks
