The slower you charge the battery the better it is for the battery life. If the battery went dead and there doesn't seem to be any reason have a local parts store load test it, it may have a dead or shorted cell and need to be replaced. The testing is free at Autozone and others like them. Please rate my help for Fixya. Thanks
I recommend using the slow (2amp) charge whenever possible. The slower the charge (in general) the better the results) I will recommend that when you are charging the battery, you remove it from the car or at least remove the cables so there is no drain on it. By removing it all together, you eliminate the possibility of damaging it (your car) from charging a damaged battery and all the nasty little things that can happen! I come from old school and although I have heard conflicting stories since, I always place the battery on a couple pieces of wood to keep it up off the ground and to avoid any damage that leaking acid can cause. Always wear rubber gloves and keep the battery away from your skin or anything else you don't want to damage. always wash thoroughly! Please let me know how you made out or if you have more questions. Thanks and good luck!

In general terms, the least amps the better. High amps causes heat and gassing but is a trade off in time.
2 amps, your battery will be nicely charged in 12 hours. 50 amps will charge in an hour, although a Booster is for jump starting a car. It is unlikely that it is charging at 50 amps. I have a good charger and it is a 2 amp / 12 amp charger. I put it on 12 amps for an hour and then 2 amps overnight.
Overcharging, or boost charging can cause over heating and buckling or the internal plates, but a short high amps charge does help to remove sulphate scale from the plates.
..
Batteries that have been left in an uncharged state will sulfate the plates and render them useless. Only by removal of the sulfate will they be useful again. This is a
very expensive process only accomplished commercially.
Replace battery and keep it fully charged to prevent sulfation. This can be done using a battery maintainer not
to be confused with a trickle charger. Maintainer only charges battery when needed not all the time like a trickle
charger. A trickle charger will also cause a battery to become dry which also damages the cells.
Most likely, Yes.
If you plan to leave your car or not to use it for a month, always remove the negative terminal of the battery. It also depends on the age of the battery, If you have an old battery then it should be 2 or 3 weeks instead of 1 month.
Maybe your battery was overfilled. You should be fine. Well, you may have to charge it again, lol. If you don't have a voltmeter to test it, just try starting. If it starts, the alternator should take care of charging it up after about 30 minutes of running. 10 amps in one hour is not too much. I thought all battery chargers sold today had an automatic function to reduce output down to a trickle charge (about 2 amps) after sensing battery was nearing full charge. My Sears charger is like that. Sure helps when you forget and leave it on all night! I've done that more than once and no ill effects.
I can't find any reference to a Homelite model 720 generator but most battery charging systems do not supply enough amps to run a car starter. Battery chargers usually work in the two (trickle) to ten amp range. Car starters need way more amps to have enough power to turn an engine over, depending on the size and number of cylinders in the motor. Some chargers have a switch with a 60 amp 'start' position to help the battery turn the motor over, but without that there is little chance the charger side of your generator will supply enough amps to help your battery.
if you are asking this because your vehicle is driven seldomly or in storage you should get a low amperage trickle charger. there are many different types but you need one with an automatic cutoff when the battery is fully charged and no more than 1 amp is necessary
If the battery is completely dead a trickle charge won't do much. These are designed to keep a good battery good. You need a regular battery charger set to 10 amps for a couple hours then 2 amps overnight. Be aware that sometimes if your battery has been completely killed it may not work for long, that is your car will start but within a few days or hours it will leave you stranded. You'll know because it will drag when you try to start it. Sometimes you get lucky and it works great for years.
Next time do use a trickle charger! Also if the charge you use is automatic then you can leave it hooked up in 2 amp mode when you are gone. Good luck!
How many amps does this charger put out????
A small trickle charger will take forever to fully recharge a dead battery, you'll need to have a battery charger that can put out enough amps to properly charge a dead battery.To clarify, the chargers sold at Sears, the large square types on wheels are the best for charging dead batteries and they also have an amp meter telling you how much the battery is accepting. After you charge your battery, you should be around 12.5 volts to 12.7 volts. DO NOT OVER CHARGE!!!
The 2 amp setting is a trickle charge, use this if you're going to let the battery charge overnight. The 6 amp is a little faster, anywhere from 4 to 8 hours depending on how low your battery is. Be careful not to overcharge if your charger does not have an automatic shutoff.
