    Default Re: Switching between power source and battery

    I'm concerned with this wallwart made-in-china trickle charger. I wanted it for testing and maintaining my new 12V battery, but I wouldn't trust it in permanent service in a metal enclosure. I've read reports of them overheating.

    I'm googling LM317 app notes and such looking for a reliable 12V 7Ah automatic charger.

    The DSC1000 runs without a battery connected (I ran it over 1 year when the battery died). That's why I wanted to run off mains first, and battery during blackouts.

    This charger seems interesting:
