Starting aid and reserve light for vehicles
First Claim
1. A starting aid for motors having a starting battery comprisinga. starting aid terminals connected to corresponding terminals of the starter battery;
- b. at least two secondary batteries normally connected in parallel between said starting aid terminals, the positive terminals of said secondary batteries being connected to the positive terminal of the starter battery and the negative terminals of said secondary batteries being connected to the negative terminal of the starter battery, said secondary batteries being sealed, at least partially rechargeable batteries having a current capability substantially smaller than the starter battery;
c. a change-over switch for interrupting the parallel connection of said secondary batteries and connecting said secondary batteries in series between said starting aid terminals;
d. discharge preventing means for preventing said secondary batteries, when connected in parallel, from discharging through said starting aid terminals; and
e. discharge allowing means connecting said secondary batteries, when connected in series, with said starting aid terminals.

Abstract
A starting aid and reserve light for vehicles, especially cars. The starting aid comprises at least two identical secondary batteries normally connected in parallel and charged together with the starter battery, when the car is in use. However, a solid state diode prevents the discharge of these batteries together with the starter battery. In case the starter battery is exhausted, being not capable of starting the motor, it can be sufficiently recharged by the starting aid. This is done by means of a switch disconnecting the diode, connecting said secondary batteries in series and simultaneously the resulting double voltage battery in parallel with the starter battery. The starting aid includes a lamp, providing a powerful, portable reserve light.
