Okay, so now we have discussed how to charge any battery, let’s move on to Li-Ion batteries. All batteries are not designed to stand fast charging as a lot of heat is produced when you fast charge a battery. This is another very cheap alternative, but the quality is not outstanding.Ĭaution: Fast charging needs a proper BMS (Battery Management System) to avoid any mishap or explosion. These variable voltage sources are pretty expensive, but you can get this option from Amazon at a reasonable price.

Then, it is carefully reduced to the battery’s rated voltage when the battery approaches full charge. A higher voltage is applied than the rated voltage of the rechargeable battery at the beginning of the charge cycle. This same technique is also used in Fast Charging. If your battery has discharged to 6V and you have connected it with a 12V voltage source, it will start to charge quickly, and as it approaches 12V, the charging speed will drop significantly. (An expensive one by FLUKE for serious sh*t) Quick Tip: Get yourself this inexpensive voltage meter by Amazon Basics to properly check your battery voltages while you charge and discharge it. The charging rate is also directly proportional to the voltage difference.

This means that if a 12 V battery got discharged and went down to 6V, as soon as you connect a voltage source above 6, it will start charging. The charging starts as soon as the potential difference rises. Once the voltage goes up to 12 V, it starts charging. It will charge when the voltage surpasses the battery voltage. The battery will not charge at this voltage. How to charge any battery without a charger?Ī 12V battery is attached with a variable voltage source having Zero Volt Output. The science behind charging a Li-ion battery is the same as charging any rechargeable (this is important) battery. The science behind charging a cordless battery is the same as charging a Li-ion battery with a charger. You can also use a 12V solar panel to charge a battery without a charger.

You can also use a laptop charger for an 18V or 20V drill battery or AA cells attached in series or another drill battery or a balance lipo charger. Using a variable DC voltage source is also a very reliable way to charge any rechargeable battery. You can charge a battery without a charger using a car battery if both are rated at 12V. This blog post will discuss how to charge a cordless drill battery or any battery without its official charger. In a worst-case scenario, the battery charger can die for various reasons. Therefore, every manufacturer provides a dedicated charger for the batteries, often inside the package. A cordless drill is of no use with a juiceless battery.
