I have purchased a Biddle M-BITE impedance tester. After I have learned to operate this multi-buck unit, I'll give a report on how useful I think it is for RE system batteries.<div><div><br></div><div>I also use a West Mountain Radio CBA II with the 10X amplifier that let's us do temperature compensated discharge tests up to 500 watts to verify the actual AH capacity of a battery. The impedance test should only take seconds per cell so I hope it replaces this discharge method of testing.<div><div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Sans'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Sans'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Sans'; font-size: 14px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; "><div><div>Kindest Regards,</div><div><br></div><div>Larry Crutcher</div><div>Starlight Solar</div><div>(928) 941-1660</div><div>Renewable Energy Products, Service and Installation</div><div><br></div><div>Mailing Address (NO SHIPPING):</div><div>11881 S Fortuna Rd.</div><div>#210</div><div>Yuma, AZ 85367</div><div><br></div></div><div>Shipping and retail store (NO MAIL):</div><div>2998 Shari Ave </div><div>Yuma, AZ 85365</div></span></div></span></div></span></div></span> </div><br><div><div>On Mar 30, 2009, at 9:07 AM, Tump wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: 'Lucida Sans'; font-size: 15px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div lang="EN-US" vlink="purple" link="blue"><div><span lang="EN"><p><span class="140460216-30032009"><font face="Arial" color="#0000ff" size="2">This comes from Jeff Skelski a guy that has been involved for quite a few years w/ batteries, EVs & Jeff also works w/ a hi freq battery desulphator group. this is his response & contact info FMI.</font></span></p><p><span class="140460216-30032009"><font face="Arial" color="#0000ff" size="2"><a href="mailto:jeffski@the-spa.com" style="color: blue; text-decoration: underline; ">jeffski@the-spa.com</a></font></span></p><p>I have been using conductance technology for 10+ years and it is a great tool. I can test a bank of 24(up to 100) batteries is less than ten minutes and get a print-out. It is only a very good guide that has the advantage to be used without disconnecting anything. The more you use a conductance tester the easier it is to learn the short-comings. It has the ability to test a battery, or a bank that is not fully charged. It is also great for matching a used battery to an aged bank. It I have a question and suspect a particular battery, I still will use my carbon-pile or load bank along with other indicators. I have been using the Midtronics and am currently testing the Auto Meter.</p><p>I use both Automotive and SLA(ah)units of different sizes. The prices do very but as the old adage goes you get what you pay for, my regular unit is an $800 Midtronics plus a $400 printer. I am not a part of the wrenches group, nor am I very good with email. I would love to join but probably can't as I am only a battery / energy guy. Jeff</p><p><br></p></span></div></div></span></blockquote></div></div></div></div></div></body></html>
