because there are cells shorting in the battery
if you keep a phone on the charger for too long, (for instance, all night,) then the battery will actually not last as long
If they're of the same chemistry and voltage - probably. But if they are too different in size the charge current can be too big for the smaller battery.
You need a 6 volt charger. When you buy a charger look for one that monitors the voltage level of the battery while it is charging and when the battery is fully charged it will turn off. Indiscriminate charging of a small battery can easily destroy it. Being left on the charger too long can boil the electrolyte out of the battery. A battery can not recover from this action and it will need to be replaced.
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.
Either the charger is too powerful for your battery, like when using a 24 V truck/tractor charger on a 12 V battery. Or there's something seriously wrong with your battery, like too low fluid level.
Yes. It comes with a charger too
No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.
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.
with the supplied charger light stays red you have to read manual its about 8 to 16 hours that I rember but i too don't have the manual anyone out there have it?
A car battery charger is too powerful for that size battery and will damage it. Check out this charger http://www.replacementupsbattery.com/Product_pages/wka12v1000.html Hope that helps!
No. The battery will be charged at a rate which is 2* the normal rate. This will cause the battery to overheat which might cause it to explode.
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.
