The best time to think about your car battery is before it goes dead and leaves you stranded. So, we’re here to test your battery regularly and replace it when its voltage is low… but not too low.
The charging control electronics BMS is disabled, if you recharge the cells, the repair works. An example is the hoverboard accumulator, for which there are several videos on YouTube. look at them and you will understand too.

If your vehicle won’t start with a fully-charged and healthy battery, the usual suspects are problems with your starter, your alternator, your ignition switch, your spark plugs or your fuses. It’s also worthwhile to clean your battery terminals and connectors if they’re dirty or corroded and see if your car will start. But the only way to be sure your battery is healthy is to test it with a voltmeter. When you have your vehicle towed to Midas, it’s the first thing we’ll check.
After cleaning battery acid from the battery, you have to recondition it. For that purpose, fill the cell with electrolytes again. The electrolyte is usually made of distilled water and Epsom salt. This allows the battery to charge quickly by avoiding sulfates. Then, pour it in the battery.

Hi battery doctor, I bought a car battery 38Ah for my Nissan Cube and used for 7 months and there after parcked it after noticing a knockin sound. Later after 4 months, I have attended to the knocking sound but now the battery is not holding the charge. I have just noticed the battery acid is a little below the cells level. Do I need to just add distilled water or follow your dead battery reconditioning process, or if better still, drain the battery and refill with fresh battery acid? Please help and thank you most sincerely in advance.
Description: it comes in handy in case you need to cut battery housing and take out internal elements. A simple knife with thin blade and handle would do as well.
Step 4: Replace the bad cell groups that you find with the closest possible match in terms of capacity and internal resistance.
There's a hidden screw under a piece of plastic. You need to pry the plastic off to get at the screw underneath. I used a very thin screwdriver to pry it off.

A car battery should be replaced when its capacity has dropped below 12 volts -- which happens to most batteries after three to seven years of use. Here are some signs that your battery is running critically low:
I've had problems with my Ryobi batteries before, even brand new ones. I find the 4ah to be more dependable than the lower rated ones. I've never owned a bigger on, no need for it. Seen a lot of different recovery techniques and this one is the simplest and makes the most sense.

The power meter reported a range in power between 2 and 93.6 watts during the charging period, consuming 0.946 kWh in total. From my utility company, that represents around $0.11 worth of electricity.
This was the second time visiting Peter's Auto, and both times I had a relatively serious problem (wheel broken off the axle and cracked fuel pump). Peter and his team fixed my car both times promptly and skillfully for a…
So if one goes bad, it's more than likely going to negatively impact the surrounding cells. If left unchecked, a bad lithium-ion battery can overheat and go into thermal runaway, which is never a good thing.
