Don't be misled by the A-Hr ratings. Battery construction for short-term high-amperage discharge (such as car starting) is radically different from that for long-duration low-amperage loads such as proposed. Ditto for deep-discharge and float charge capabilities as well as battery chemistry. We run across these questions frequently in design of communication site standby power. I would examine the specs very carefully. ---- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 >From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
