The 56 V2A charger cannot replace the 42 V2A charger.
It is dangerous to use an unmatched charger to charge the battery. This can easily cause irreversible damage to the battery, significantly affect battery life, and even cause spontaneous combustion. or explosion safety accident. It is therefore recommended to use a suitable charger to charge the battery.
The 42V2A battery charger is an electronic product with a rated voltage of 100-240Vac.
1. The dangers of charging high voltage batteries with low voltage chargers
First, we need to clarify one principle. High voltage batteries charged with low voltage chargers. will discharge due to the pressure difference. The situation is as follows:
(1) Once the lithium battery is charged to a certain level, it can no longer be charged, i.e.say that it is still not fully charged. In this case, the battery will deteriorate quickly during use. Consumption of all power will affect the long-term use effect, battery life will be shortened.
(2) The battery cannot be charged and the battery remains discharged, that is, the output voltage of the charger is the same or very different from the voltage of the lithium battery after discharge.
(3) The output voltage of the charger is lower than the termination voltage of the lithium battery after discharge. Not only will it fail to charge, but the lithium battery will continue to be deeply discharged, causing the problem. the battery will be over-discharged, and even lithium precipitation will damage the battery, shortening its service life.
2. The dangers of charging high voltage batteries with a high voltage charger
Charging voltageThe output of the high voltage charger is the overload protection voltage of the high voltage battery. In this case, we often speak of overload. What exactly are the risks? It is generally accepted that high voltage charging can increase charging speed and shorten battery charging time. This is only achievable within the battery's permitted charging rate range. Otherwise, the battery will heat up too quickly, causing the chemical activity inside the battery to be too high, making the battery internally unstable and prone to spontaneous combustion or explosion accidents. Of course, if the quality of the battery is reliable and does not ignite or explode spontaneously, the battery may swell and be discarded.
Of course, if the charger output voltage is only slightly higher than the battery overcharge protection voltage, there may be no problem ina short period of time. However, if the charger is used frequently, the lithium battery. will swell due to lithium precipitation and will be discarded.
