Every time your battery falls below the voltage range that it was designed to work at, there is permanent damage done to the battery cells. This, itself, is not dangerous but it is very bad for the battery.
After a visual inspection to make sure there are no burns anywhere, check to make sure the voltage of the battery is within spec. Also, check to make sure it's holding a charge by checking its voltage with a multimeter right after you charge it. Another thing you can do is feel the battery to see if any particular spot is producing more heat than other areas of the battery pack. If after doing those things you feel like your battery might be bad, then you will have to tear it down enough to be able to measure the voltage of each cell group. Find the group or groups that have a lower voltage than the rest of the cells and remove it from the pack. After that, those cells just need to be replaced.

Yes. A battery pack contains many battery cells. Not all of them are going to be bad. Depending on the battery pack's construction, it can range anywhere from extremely easy to excruciatingly difficult to open the battery and remove the bad cells. As long as you can identify the bad cells and remove them from the battery pack, you will be able to repair the battery. It also may be as simple as balancing the series groups that are out of balance from the rest of the pack. It could even be as simple as the BMS went into safe mode and needs to be woken up.
The 12V/10A and 24V 7Amp smart battery charger is a helpful tool for users to charge the battery of car and motorcycle safety.
If you still only get a red flashing light and the battery won't charge, boost the battery some more. I find the battery charger will recognize that the battery is good again when you boost it to between 10 and 14 volts.

As technically-advanced as iPhones may seem, they tend to have a mind of their own. This can come in the form of unexpectedly powering down in the middle of writing an email, while sending an invoice to a client, or when looking at the pictures your uncle sent of the family reunion.
I use an ASUS F200 LA computer. The battery was not charging. When plugged in, it will display charging, but it won't leave 0%, and it switches off immediately when it is not on an external source of power, so an engineer helped me in boosting it by charging it through its positive and negative terminals after loosing the battery, then it charged to 58%, but it will still not increase when charged with the laptops charger, and when the power adapter is unplugged, it switches off immediately. Please what can u do.

To assure continued operation when changing the cells, supply a secondary voltage of same voltage level through a 100-Ohm resistor to the circuit before disconnection. Remove the outside supply only after the circuit receives voltage again from the new cells. Furthermore, some fuel gauge chips run wires to each cell. These must be reassembled in the correct sequence beginning with cell one, then two, three and so forth.
