Just a little under an hour for 1100mAh-2200mAh batteries but probably 2 hours and up for bigger batteries. I charged 2 1600mAh batteries (1 being 8.4v an the other being a 9.6v) in under 2 hours.
There is no only one way to charge it and that is with a battery charger. A 15 amp battery charger will charge it about as fast as it needs to be charged.
Yes, the only difference is one will charge twice as fast as the other! -Dale
A smart charger is a lot better for your airsoft batteries. It charges your batteries in less than half the time it would take for your batteries on a wall charger. They are also a lot better for your batteries because batteries have memory. Say you have 2000 mAh of energy inside your battery. You use it until it has 1500 mAh left. If you plug it into a standard wall charger, by the time it's done charging, you won't have 2000 mAh of energy, you will have 1500 mAh. A smart charger prevents this. A smart charger also goes on trickle charge when your battery is done charging, so your battery doesn't overcharge or overheat. Trickle charge is when the smart charger creates a equillibrium of battery to charger, so that the charger charges the battery at the same rate that the battery uses energy. To sum it all up: A smart charger is better for your batteries and charges them faster, without damaging them. I personally have one, and it is well worth the money. Also: mAh stands for milliamps. This is the amount of energy storage the battery has. The higher the mAh, the longer the shooting time.
A long low charge is best for the battery. A fast high charge can lead to battery damage/explosion. Purchase a small battery charger and follow directions.
depending on what charger you use it could be from 4hrs with a wall charger to 10 minutes on a smart charger
Use a battery charger with a 2amp charge. Takes a few days. These small batteries don't like to be charged too fast with high amps.
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.
Connect a battery charger to the battery and let it fully charge. Do not charge it with the cars alternator. If it will not accept a charge the battery needs replacing. Connect positive (+) red cable to positive post and black negative (-) cable to negative post. Trickle charge the battery do not fast charge it as the charge won't take. Sure it will start the car a few times but a good charge to a battery is one that is done slowly
This can depend on the charger and the battery. I'll go off what most people i know use commonly. If you have a fast charger and a 1800mAh 7.2V battery, then it should take a little over an hour. Obviously bigger mAh batteries take longer to charge as they last longer.
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.
I think you will find that this is not at all recommended. Different battery types have different ratings for charging current, voltage when charge is complete, trickle charge current and also temperature they can handle. Using a charger that is not designed specifically for the battery type you have can cause the battery to be charged too fast or too long, which can shorten the life and capacity of the battery - and worse, could cause unsafe pressure buildup.
The answer depends upon the construction of the 6 volt battery. If you can treat it as two 3 volt batteries then the answer is YES otherwise NO. Charge each section separately inserting a low wattage torch bulb between the charger and battery cell to limit the current. Choose the bulb to prevent execissive charging rate; an ammeter would come in handy. The main risk is EXPOSION if you charge too fast! Put the battery to be charged inside a strong box for safety. If in doubt buy a new battery charger, they are cheap.
