But it''s not copper, it''s steel, and probably an alloy. After a quick rush around Wikipedia, let''s assume it''s 50x more resistive than copper, so has a resistance of about 5mohm. 12v dropped across 5mohm would give a current of 2400A. The CCA of the battery is way below that, so the wrench is not limiting the current, the battery is.

I am not asking how the battery gets damaged, because that answer is straightfoward.. What I am asking is why lithium-ion chargers allow batteries to be damaged by excessive charge current in the first place. My understanding is that all lithium-ion chargers already support current limiting features in response to battery temperature (e.g. as part of "JEITA compliance"):

Does amperage matter when charging a battery? (Solved).

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.

What is More Important: Volts or Amps for Charging [Solved]

Are amps crucial for charging a battery? Amps are important for charging a battery. They determine the flow of current from the charger to the battery. A higher amperage results in a faster charging speed. But, batteries can only handle a certain amount of current. Going over this limit can harm the battery. How do I calculate charger watts?

Battery Amps vs Volts: What''s the Difference and How They Affect

Current rating refers to how much current a battery can supply or deliver, measured in amperes or amps. Voltage, on the other hand, refers to the electrical potential difference between two points in the battery, measured in volts. Current rating determines the battery''s capacity to supply power, while voltage determines the battery''s potential to deliver

Can I Use a Charger With the Same Voltage but Different

I could agree with your definition of Voltage – the ''push'' on the electrons that tries to make them move and make a current, but not your definition of Current. The load / laptop / whatever does NOT pull – it lets the current through; faster if the resistance is low, slower if it''s high. Current is how fast the electrons (that carry the charge) are moving.

Does amperage matter when charging a battery? (Solved).

For example, if you have a device that can utilize 2 amperes and you''re using a charger that supplies 3 or 4 amps, then the device will only use 2 amp and the rest will have no effect. How does amperage affect battery charging? As we all know, battery capacity is measured in mAh (milliampere-hour) which is amperage over time.

Why does a battery have a limit for current in amperes?

With the over 600 cold cranking amps inside a car battery, there isn''t a noticeable ''limit'' when something goes wrong. The electrochemical reactions in the battery can only take place so fast.

Why is amperage important when charging a battery?

What if I charge a battery with low ampere?

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.

Can I charge a battery with more amps?

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.

Can You charge a battery with less current?

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.

Can You charge a lithium battery with a high current?

The battery charging current generally uses ICC. In order to protect the battery cell, it is not recommended to charge the lithium battery with a high current. If the battery is charged with a low current and a large current, it will heat up quickly and damage the battery. If you want to prolong the life, you can charge it at 0.3C.

Why does a high amperage charge a battery faster?

A higher amperage means the battery charges faster because it gets more energy in less time. Fast charging technologies often focus on increasing the amperage to reduce charging duration. This is handy when you need a charge in a hurry. But remember, each device has a limit. Exceeding it can cause overheating and battery damage in some cases.
