Battery Backup Circuit. Given the presence of diode D1, the backup battery sees approx. 13.3 volts, which as it turns out is not sufficient to charge the backup battery. Have you found your backup battery actually charges with this circuit? BTW, your assertion that R2 will charge the backup battery with 90 ma is not correct, as the only way 90 ma would flow through R2
BATTERY_BACKUP_1_Circuit Diagram World. Four nickel-cadmium batteries connected in series provide automatic backup for 5-V supply of digital clock. Under normal AC line operation, battery is continually being recharged with half-wave rectified and unfiltered supply that allows internal chemical reactions to settle between pulses of charging energy.

Electronics Forum (Circuits. The circuit posted by Colin has no current limiting other than what MAY be intrinsic in the wall-wart. It is an extremely poor lead-acid battery charger. 1. No current-limiting (likely to blow-up or overheat the wall-wart) 2. Very primitive voltage regulation (using Vbe of transistor, which has very soft knee) 3. Extremely temperature sensitive
