It seems like you're talking about a battery or accumulator that doesn't hold charge as well as it used to. If the battery drains quickly, it's likely that its performance has degraded due to age or internal cell damage. Possible causes: Battery age: Batteries and accumulators have a limited lifespan, and over time, their performance will decrease. Charging issues: If not charged correctly or if it has been overcharged, the battery might not function properly. Battery technology: Some types of batteries have shorter lifespans, particularly lithium or ni-cd batteries. Solution: Consider replacing the old battery with a new one for better performance. If you still want to use the old one, you can try "reconditioning" for some types, though it's not always effective. Feel free to ask if you need more details!
You're absolutely right. The battery's performance depends heavily on the load current. When only a small current is drawn, like a few milliamps, the battery can still last longer without performance issues. This explains why the battery might still function well under light loads, but drains quickly when exposed to heavier currents. Each battery has different performance characteristics based on the amount of current it needs to supply. Thanks again for the clarification!
Приходилось не раз оживлять такие батареи. Но как это в вашем случае она не взорвалась при ТРЁХКРАТНОМ превышении напряжения? И почему обратная полярность? Заряжала от щупов авометра в режиме измерения сопротивления. Время буквально пару - тройку минут, иначе раздувается!
Yes, charging batteries in this manner, as described in the video, can indeed be very dangerous. Overvoltage and reversed polarity can lead to explosion or overheating, especially with lithium batteries. Lithium batteries are sensitive to improper handling, and if they are charged or discharged incorrectly, it can lead to serious consequences. In your case, when the voltage exceeds the norm several times, and charging is done through the multimeter in resistance measurement mode, it can severely affect safety, as the multimeter is not designed for such use. Ideally, a proper charger designed for the battery type should be used, with protection against overvoltage and reverse polarity.
@@Alotipsalo Нет, Вы не поняли суть моего ответа! На щупах авометра в режиме измерения *СОПРОТИВЛЕНИЯ* есть напряжение от его СОБСТВЕННОЙ батареи. По сути авометр превращается в "источник тока" в отличии от "источник напряжения" ток у него стабилен и не меняется от сопротивления нагрузки! Всё это есть в учебнике "Теоретической электротехники" Авометр я пишу, а не мультиметр, подразумевая - стрелочный прибор. У него ток побольше! Скорее всего Вы таких не застали 😁😁😁

Moze to ali baterija kratko radi brzo se isprazni nije kao nova
зависит от тока нагрузки, в данном случае всего пару миллиАмпер!
