<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;"><div>We got one shipment of thick plate 2V that apparently had been mistakenly shipped with the wrong electrolyte mix.. the Battery folks were pretty good about ponying up.. they sent me everything I needed to get things straightened out.. (Including $$ for the hassle).. Basically they had me set the Charge Controllers a Little Hot to burn off Water, then charge the snot out of them (like on EQ all week end). after the return amps dropped below like 3-5% of the normal charge rate, we'd let things rest for a while and then check SG (temp compensated).. My take away was the notion that the batteries were designed to be "fully charged" when the regulated charge rate dropped below 3-5% and the SG averaged 1.28.. The Tech guy also told me that they used a constant current of like 80A for days for their commissioning charge... The biggest problem I've been having is getting folks head around the scale of the difference between thick plate technology and their old UL16s.. They sure can take a whole lot more to charge when they're down... Good Luck.. db<br></div><div><br></div><div><br>Dan Brown<br>Foxfire Energy Corp.<br>Renewable Energy Systems<br>(802)-483-2564<br><a href="http://www.Foxfire-Energy.com">www.Foxfire-Energy.com</a><br>NABCEP #092907-44</div><div><br><br></div>

Generally speaking, if you find that the batteries test reading are a little low, they are probably just a little discharged. After recharging the batteries, test them again. If those readings are low, then contact the manufacturer with the data.

I'm not talking about load testing, i mean just basics...voltage, specific gravity and electrolyte level.<o:p></o:p></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;"><o:p> </o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;">I recently received some batteries (24 x 2V) and before putting them to work i tested all the voltages, SG's and levels. Voltages were all with-in 0.016 V (2.1-2.084). The SG's were within 0.037 (1.281-1.244). Yes, the one with the lowest SG also had the lowest V. <o:p></o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;"><o:p> </o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;">What concerns me a bit more than the few cells with lower SG is the consistent low levels of electrolyte. All cells were between 3/4" and 1-1/2" below full, which is 1/4" below the bottom of the vent well tube.... with one exception that was bang-on full. Interestingly, the one full battery was the only one with a different date code than the rest. <o:p></o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;"><o:p> </o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;">Should the various levels of electrolyte mentioned be acceptable when a battery is brand new, straight from the mfgr? How bout the SG's?<o:p></o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;"><o:p> </o:p></div></div><div><div class="MsoNormal" style="font-size:12pt;margin-left: 0.5in;">I'm considering adding electrolyte from a local battery shop instead of distilled water to top up all the batteries.
