Assuming it is like any typical lead acid battery charging voltage of a six cell lead-acid battery, to fully charge the battery, is over 13.8 volts. It has to under 14.7 volts to prevent excessive gassing, 14.4 volts is generally the gassing threshold.
Most of the stuff here that includes a voltage chart at the end, although geared for cars and drag racing, is applicable to most lead-acid batteries: http://www.w8ji.com/battery_and_charging_system.htm 73 Tom ----- Original Message ----- From: <[email protected]> To: "Elecraft Reflector" <[email protected]> Sent: Monday, May 31, 2010 10:42 AM Subject: [Elecraft] K1 OT lead acid battery charging > Ok, I have a 12vdc 5ah lead acid battery.
