I doubt the charger is putting out 30 Amps on a slow charge. need more info on battery and charger.
No.
There are a few variables to take into account here. The discharged state of the battery and the current produced by the battery charger on the slow charge position are two of the most important. The amp/hour size of the battery is another governing factor.
Not sure if the question is what to charge the battery with or how to charge the battery. So, I will address both: A regular battery charger can be used. IF you are going to purchase one, you really don't need a top-of-the-line, expensive charger. A simple 2 to 6 amp slow-trickle charger will do the job. To charge the battery, connect the red charger cable to the positive battery post and the black charger cable to the negative battery post, then turn on the charger until the battery is charged. If necessary, clean the battery posts and cables before charging. The battery charger will have more complete details for charging the battery.
I would recommend a slow charge of 10 amps at 12 volts.
Disconnect the positive battery cable and charge it with a slow charger. Clean and reconnect the cable once the battery is fully charged.
Fully charge the battery with a slow charge battery charger. Then take the battery to an auto parts store and have it tested. If it is over 4 years old it is probably in need of replacement.
of course, you can do it. Sometimes, when the car battery is dead, we will use the battery booster to connect another car battery to charge it. This process needs a cable. Be careful, if you plan to do it on your own. My booster is also a charger. it has different settings for slow charge, fast charge, and boost.
turn off the ds before it runs out of battery and it charges extremly slow but it charges
A twelve volt charger will charge twelve volt batteries only unless it has a feature that allows you to change the chargers voltage. But on fast or slow charge 12 volts is 12 volts so most 12 volt chargers are only good for 12 volt batteries.
Many times a battery that was allowed to "go dead" by sitting will end up being non-usable. If you have access to a simple charger, connect it to the battery to see if it will take a charge. If not, don't fight it, just remove the battery, take it to an auto parts retailer and see if they can charge it. If not, just replace the battery. Charge it with a slow charger of around 10 amps. Make sure to use an automatic charger as not to over charge. Clean the post connections, and if if is not a maintenance free battery make sure the cells are not dry. Only add distilled water.
is your battery Low or poor?? Charge your battery on slow charge for 8hrs to give it a good deep charge, Installing an alternator on a low or dead battery will ruin it and also not charge your battery properly.. An alternator is not a battery charger its a battery maintainer!!
pick up a trickle charger from your local motorcycle shop. i leave it on overnight and it is charged in the morning.
