It's a lead/acid (maintenace free), 12 volt 3 amp hour battery.a 1. How 'bout some suggestions on charging it. -- I have an extra PC power supply that puts out 12v DC. Can/should I use this? -- I can cobble together a 14v transformer (from Radio S.....) along with a rectifer & a couple of resisters..... Is this any better or worse? 2. What's the best way of telling when the battery has a full charge? Thanks, Mike Hatalski mikehat@locus.com
