Lamp L1 will glow brightly and the LED will be out when the battery is low and being charged, but the LED will be bright and the light bulb dim when the battery is almost ready. L1 should be a light bulb rated for the current you want (usually the battery capacity divided by 10)．Diode Dl should be at least 1 A，and Z1is a 1 W zerLer diode with a voltage determinedby the full－charge battery voltage Π11nUS 1，5 V。After the battery IS fully charged， the circuit、vill float it at about battery capacity divided by100 mA．
