1) The battery has a maximum power it can provide. For example, if this power is P = 100 W, then since P = RI^2 the current will be I = (P/R)^0.5 = 31.6 amps and the voltage V = RI = 3.16 V. 2) The battery has a maximum current it can provide. For example, if this current is I = 5 A, then V = RI = 0.5 V.

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons. When a battery is connected to an external electric load
A swollen battery explosion is often caused by the buildup of gases inside the battery, which can lead to increased pressure and potentially cause the battery to rupture. This buildup of gases can be the result of a variety of factors, including overcharging, high temperatures, or physical damage to the battery.
Once thermal runaway begins, the battery''s temperature rises rapidly, often exceeding 700°C to 1000°C. This extreme heat causes the battery''s cells to break down, releasing flammable gases. If the battery is in an enclosed
