Can a battery tender charge a dead battery?

A battery tender is a device that optimizes the life of your car or motorcycle battery. It does this by charging it when it senses that the charge has dropped below optimum levels, and then maintaining it at optimum level during idle periods. But can a battery tender charge a dead battery?

It’s true that a drained battery won’t charge if you try to give it power from an empty cell. The polarity sensor inside the charger lets out just enough voltage (2 volts) in order for your gadget or phone screen not turn on by mistake because of how sensitive they are when detecting whether something is positive or negative facing up at them and would result with damage both ways!

Then, can a completely dead battery be recharged?

A dead car battery can be restored to full charge by gently heating the plates inside of it with a soldering iron. The solution is made from water and baking soda which releases oxygen when heated, this causes acid Rainer cells contain an 1800 volt positive electrode (anode) connected through wires or contacts that make them capable enough for recharging zinc-based batteries such as those found in cars, trucks etc..

The metal within these types may rust if not charged up occasionally so you’ll need something like an old propane torch welder’s tip because they are really just large versions H2Ofire welding rods specially designed.
