dewalt 18 volt battery positive and negative

In short, It may partially or fully damage the charger circuit. The current flowing to the battery through the charger may burn out the electronic components inside the charger (if there is no reverse protection is provided by the manufacturer).the charger negative and positive connected to the battery positive and negative terminals respectively, the following may occurs: If by chance, accidentally or intentionally the battery charger (or solar panel, Inverter etc) connected to the wrong way around i.e. Connecting a battery to another battery with reverse polarityĬonnecting a Battery to the Charger with Reverse Polarity.Connecting Battery to the load with reverse polarity.Connecting a battery to the charger with reverse polarity.what happens to a battery if you recharge it the wrong way around? or what happens when charging a battery using reverse polarity with a charger? Due to the wrong connection, a current may start to flow in the circuit and may cause some serious injuries and damage to the equipment.Įnough the basic, now come to the point i.e. source or load Negative to the Positive of battery and source or load Positive to the Negative terminal of the battery. Battery Reverse Polarityīattery reverse polarity is the case when the source (for charging) or load cables are connected incorrectly i.e. from positive electrode the negative electrode. The electrical (conventional) current flows in the opposite direction i.e. In other words, the electrons (electronic current will start to flow from the -Ve terminal to the +Ve terminal. If we connect these both terminals through a conductor having a resistance, the current will start to flow due to the potential difference on both points. Positive Plate Negative Plate Electrolyte Discharge Positive Plate Negative Plate Water The combined chemical reaction in the battery can be written as follows during the charging and discharging (or discharged and charged cell) of lead acid battery: A light sulfuric acid (H 2SO 4) is used as an electrolytic solution in the battery for proper chemical reaction. For example, the positive plate is Lead per oxide (PbO 2) and the negative plate is sponge lead (Pb). There are internal plates in the batteries (lead acid, alkaline etc) known as cathode (positive “+”) and anode (negative “-“).

The flow of current in discharging mode (battery supply power to the connected devices) is opposite in case of charging (external source provides energy to) the storage battery. In other words, the chemical components in the battery can be reversed (to the original and prior shape) by changing the direction of flow of current in the battery. The chemical reactions in secondary cells are reversible in case of proper battery polarity connection instead of reverse polarity. We know that a secondary battery (also known as an accumulator) is a device that converts the chemical energy into electrical energy and stores in it for later usage.
