🔋 The battery still has fire, but why is the device unpowered?
Many people may have encountered the problem of "batteries are still on fire, but the restarter is not stuck," or it is not used for long, it seems that batteries still have capacity left. In fact, the problem may not be caused by "battery capacity" alone, but may be caused by higher "internal resistance" with service life.
A new battery with a low internal resistance value will be able to supply the current at full capacity, allowing the device to run strong, low-power and low-heat, suitable for high-current devices such as electric drills, cars or high-power appliances.
On the other hand, when the battery starts to deteriorate, the internal resistance will increase, resulting in a rapid voltage drop, not fully current supply, so the device is sluggish, falling or sometimes not on, and produces more heat and shorter operation.
A simple summary is that "capacity" tells how long the battery lasts, but "internal resistance" determines whether the battery will have enough force to drive the device.
So when checking batteries, don't just look at Ah or Battery Percentage, because batteries with lights may no longer be able to supply full power.
