DC definitely, all car batteries - all batteries.
The majority are all 12 volt.
There are a number of places where one can purchase a Harley Davidson battery. For instance, JP Cycles, Throttle Batteries, and Battery Mart all carry Harley Davidson batteries.
All Harley Davidson motorcycles have used a 12 volt battery since 1965. Prior to 1965 they used a 6 volt battery.
You cannot do this. If it were a 36 volt charger you could connect three 12 volt batteries in series and charge all 3 at the same time. But this is a 32 volt charger which I have never heard of.
All auto batteries are 12 volt except very old cars prior to the late 50s.
Charge the battery fully. That is all you can do.
To maintain the 12 volts using four batteries they have to be wired in parallel connections. This means that all of the positive posts are connected together and all of the negative posts are connected together. The total sum of all of the batteries will equal 12 volts.
All Batteries are DC or Direct Current.
How to hook up 6 8v batteries in searise <><><> Batteries connected in series have the negative (-) of one connected to the positive (+) of the next, until all 6 batteries are connected.
You do not need three 12 volt batteries to get 24 volts, all you need is two batteries. So I assume by using three batteries you want to increase the amperage. Wire two of the batteries in series and then wire the third battery to the second battery in parallel and you will have 24 bolts. Or you can just wire two 12 V batteries in series to get 24 V.
1.5 volt batteries come in a variety of sizes: AAA, AA, C, and D are the most common. Grocery stores, drug stores, electronic stores, and variety stores as well as many popular etailers sell these batteries.
