Abstract

Figure 1 shows a typical rechargeable battery used to power a portable radio. The battery has a set of contacts, Ji and J2, through which the battery is charged, and a set of contacts, J3 and J4, through which power is supplied to the radio. Diode CR1 is used to prevent accidental shorting of the battery across Jl and J2 while the battery is attached to the radio. When the battery is removed from the radio it can still be shorted across J3 and J4.
