It doesn't completely stop. Instead it automatically drops the the charge rate to a trickle charge to maintain the battery at full charge.

answer 6
This charger is fully automatic, it will turn on when the battery needs to be charged, then turn off when it is charged.
The charger comes with a 18" pigtail that connects directly to the battery, that pigtail then quick connects to the charger. This is an excellent set-up, since most motorcycle batteries (mine included) are buried in the motorcycle. Only a quick connect to connect and you can (Pardon the pun) set it, and forget it. Leave it connected all winter, and it will keep your battery charged safely.

Schumacher does not recommend this charger to charge a large dead battery. From the manual "However, if you use the battery charger to charge a large battery, such as a marine deep cycle battery, that was not fully charged, you may lose some of the battery’s capacity. This would cause the large battery to be unable to hold a charge and become useless. Therefore, we do not recommend charging a large battery with this unit."

It depends greatly on the type of battery charger you are using. Typically the more amps the charger is capable of the quicker the charge time. If you goal is to just crack the vehicle, there are special charges that can do that immediately. A 10 amp battery charge can fully charge a dead car battery in about 6 to 8 hours. 1.5 amp charger would take a good bit longer.

answer 1
typically 3 to 4 hours will produce a sufficient charge if its a good battery. If not, it will not hold a charge and the automatic voltage adjuster will put out an error signal. The lighted indicators will let you know if the battery is fully charged, charging, or aborted due to a more significant battery issue in which case replacement is recommended.

It's not really a charger. It's more for a battery that doesnt get used much. Like a motorcycle parked for the winter, or a car that sits more than it gets driven. It's to maintain a full charge at all times while it sits so the battery doesnt eventually run dead and go bad. Lead batteries are ment to have a full charge at all times.

Depends whether you're just looking to maintain the battery in storage, or actually recharge it after discharging it. This charger will maintain an already charged battery of that size, but will recharge a discharged battery slowly enough that the battery will start to sulphate. If you intend to recharge after use, buy a bigger charger.

No. This rectifier is designed for 120v. So 240v when stepped down will double the voltage through the diodes and burn them up.

You could connect multiple 6 or 12V batteries in parallel. The batteries would equalize to the same voltage as the charger is charging them. It's less than ideal though.

I have a boat with a two 12 volt battery bank so I can select either one or both. They are in parallel. One is an engine run type battery for starting, etc. The other is a house battery deep cycle for when we are at anchor at night, etc. Can I hook up the single Maintainer to both batteries at once when we are gone to maintain them?

answer 3
From Schumacher FAQ's. "To charge both batteries at the same time you need to make sure they are wired in parallel. The two batteries should be connected to each other positive to positive and negative to negative. Then attach the charger positive to the positive on one battery and the negative to the negative of the OTHER battery. Do not hook both leads up to one battery." Make sure the batteries are charged and not completely dead before you use a maintainer. Also, I would recommend the 2 amp maintainer for two batteries.

Absolutely. I used it to maintain three 1300aH batteries used to start my semi. The first time I hooked it up to charge the red "Connected" light began to flash after being left overnight. There is no mention what this means in the manual so I unplugged the unit then plugged it back in. It began to charge normally again. The next day I checked on it and it was now in "Maintain" mode. I believe that the 3 batteries collectively took longer to charge than the charger is designed for and it "timed out". Once it was plugged back in it didn't take as long to charge so it went in to "Maintain" mode and worked as it should.
