Solar garden lights are intended to provide light for about four to six hours in full sun, less in less sun. As an alkaline battery is charged in a completely different circuit than one used for NiCd or NiMH batteries, what is more likely happening is that your garden lights are simply running off the battery without the solar cell beingGet a Quote
They contain a diode for charging the single NiMh cell from the solar panel, but also use the voltage from the solar panel to detect when it's dark enough to turn the light on. The circuit pulses a small inductor at about 100kHz to step up the voltage to drive the LED in a similar style to a Joule Thief circuit.
