I use Don's system described below in #2) with the A&A charger and recommend it. It keeps the K2's battery healthy, and I also use it for other gel-cell batteries around the shack. Plus, when out in the field, the added power jack on the back of tyhe K2 makes a convenient spot to connect an analog expanded-scale DC voltmeter to monitor the state of charge (even though the K2 can also monitor its own voltage). The meter I use is a Zantum Technologies model ZAPV15 "12 Volt Lead Acid Battery Capacity Charge Meter" with a nice multi-colored scale.

See my website www.w3fpr.com for information related to 2) above. -- View this message in context: http://n2.nabble.com/K2-Battery-Charging-System-With-out-Mods--tp1120435p1122331.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
