Vince8282 Posted September 29, 2015 Share Posted September 29, 2015 Yeah! batteries are a "specialist" subject on their own and of course good old ohm's law ends with "provided the temperature remains constant" (which it doesn't). The other situation comes into being too when you have a detector covering a high traffic area and comparing the life of it to the life of one stuffed (technical term) in a store room that is hardly ever entered. Quote Practice in the morning, practice at night. Practice in the evening, until you get it right. Only make sure you are practising in the right way at the right time for it.

secureiam Posted October 1, 2015 Share Posted October 1, 2015 need some temperature curves and discharges for each battery to help may be? Quote Link to comment Share on other sites More sharing options...
Vince8282 Posted October 1, 2015 Share Posted October 1, 2015 Not much point really as the weather men can't accurately predict the temperatures so we have no chance to do so.

secureiam Posted October 2, 2015 Share Posted October 2, 2015 temperatures externally are more random than internally, but batteries that do well regardless of the changes in temperature are better than those that vary significantly its all relative?

james.wilson Posted October 2, 2015 Share Posted October 2, 2015 tis but the temp is less relevant to life than it is with sla. High temp does affect primary cells but not as much as sla Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

WDT Posted October 3, 2015 Share Posted October 3, 2015 Pretty much the only way, I notice the once-available ACT Lithium Tester is long discontinued... They might have brought out a new one http://www.actmeters.co.uk/battery-testing/336l-3v-and-36v-lithium-battery-tester Quote Link to comment Share on other sites More sharing options...
