You can always charge a battery with less current. Heck you can even not charge it (no current). But if the battery wants to charge with more current than the adapter can handle, the adapter might overload. If it's a good adapter it will just switch off. If it's a crappy one it might catch fire. So your choice.
Even the modern charger that comes with the devices these days also control the output amperage. You can not supply the device with more amps than it can accept the only way this is possible is if you use a charger supplying high voltage which will cause too many amps to flow and can result in heating and damage to the battery.
Amperage is the measure of electrical current, and it is critical to understand when charging a battery. A higher amperage will result in a cooler, steady power supply and shorter charge time, while a lower amperage can cause the charger to overheat.
Electrical Engineering Stack Exchange What if i charge a battery with low ampere.? Assuming we have a mobile-phone LiIon battery and a charger which is only able to supply less ampere than the original one, will it damage the battery if i charge with less ampere charger than the original one.
(Solved). There are a lot of factors that go into charging a battery, and amperage is one of the most important. Amperage is the measure of electrical current, and it is critical to understand when charging a battery.
Charging is the process of replenishing the battery energy in a controlled manner. To charge a battery, a DC power source with a voltage higher than the battery, along with a current regulation mechanism, is required. To ensure the efficient and safe charging of batteries, it is crucial to understand the various charging modes.
How Much Current is Required to Charge a 12V Battery?
The rule of thumb is that a battery''s charging current should be about 10% of its capacity for lead-acid batteries and up to the full capacity (1C) for lithium-ion batteries. In simpler terms, if you''ve got a 100Ah lead-acid battery, you should be …

Debunking Lithium-Ion Battery Charging Myths: Best Practices …
The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete.

Dead Battery? How To Charge a Car Battery Yourself
How Long Does It Take To Charge a Car Battery? Charge time depends on the battery charger you use. A higher amperage battery charger will result in a faster charging time, but it can damage your battery and result in a shorter lifespan. A lower amperage (between 2-6 amps) will give you a full charge in a few hours and is healthier for your battery.
