Message-ID: <1900@eastman.UUCP> Date: 6 May 91 19:55:26 GMT Sender: news@eastman.UUCP Reply-To: levi@kodak.com (Ilia Levi) Distribution: na Organization: Eastman Kodak Lines: 11 How can you tell when a lead-acid (car) battery is fully charged? I want to build a charger for the backup sump pump system in the basement, and don't want to overcharge the battery (heard it was bad). How much voltage should a charger put across the terminals? While we are at it, what about the Ni-Cads? Tired of wet basement :-) levi@kodak.com
