BATTERY CHARGERS AS POWER SUPPLIES. There are situations where a battery charger may need to function as a power supply, as well as maintain batteries. This can be when designed into a UPS (Uninterruptible Power Supply), or when testing or operating a DC system powered by batteries. Not all chargers are suitable for power supply operation.
A "switching" power supply (like virtually all modern computer power supplies) works by "rectifying" the incoming 120V 60Hz (in the US) AC power into DC (at around 170 volts), "filtering" with capacitors, then using a semiconductor circuit to "chop" the DC voltage around 1000 times a second to turn it back into crude AC.
And you''re flatly not supposed to trickle-charge a li-ion to keep it at 100%. You''re supposed to STOP, as in 0 mA, charging once the battery is fully charged. If the terminal voltage drops far enough the laptop will start charging again, but not "trickle-charging". –

Finally, make sure that the polarity of the power supply is correct for the type of battery you are using. Can You Charge Battery Through 12V Outlet? There are a few ways to charge a battery using a 12V outlet. One way is to use a 12V charger that plugs into the outlet.
Why isn''t any 13.8V power supply already a 12V battery charger? Even the smallest lead acid, or sealed-lead-acid battery can draw an enormous number of amps when it is fully discharged and you apply voltage to it. Few power supplies are big enough to do this, and those are expensive.
Connect the charge controller to battery adapter cables to the battery terminals on the charge controller. The positive cable should have a fuse. Don''t connect them to the battery just yet. Connect the charge controller AND 12V to 5V converter to the battery. Your charge controller should turn on.
A regulated 12 volt power supply can not fully charge a discharged 12 volt battery, but it makes a good float charger if the output voltage is correct (again, 13.5-13.8 volts for a 12 volt system). Check the water level in the cells often, and replenish as needed with distilled water.

Whether or not your battery will be able to fully recharge things like larger battery packs for tools, however, will depend on the total size and battery capacity of the power supply you choose. My Yeti 200X, for example, fully charges my Milwaukee M18 Battery in under an hour and still has more than 50% of its capacity remaining.
Charging a 12 V lead–acid car battery A mobile phone plugged in to an AC adapter for charging. A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it.
