I just looked at the north star site. Can you tell me which battery fits our trucks? 22PB. They don’t have a vehicle drop down unless I missed it.I saw some of that info, but 12.7V is 100% full. 12.6V is 95% full (roughly) and the trucks do a fine job keeping the voltage above this limit if used regularly.
(All lead batteries need to be above 90% SOC (state of charge) to prevent sulfating.)
The three main selling points of Northstar batteries:
1: They have very little resistance- similar to Lithium, so they recharge extremely fast, which decreases the number of cycles you use, which increases its life even more.
2: These are the only Lead batteries that will provide roughly 500 CCA at 5% SOC. To put this in comparison, most Flooded/AGMs will not start anything at 60% SOC or less.
3: They are exceptional at holding their voltage under a load-
Example: I ran 25A discharge tests on about a dozen different AGM batteries sold in the USA and Northstar smoked every other option:
25A discharge basic results:
Northstar: Held 12.65-12.70 volts for 30+ min. And was the only brand that was reserve capacity was underrated on the label.
Odyssey: Held 12.65-12.70V for 7-10 min.
Was close to meeting its reserve capacity rating.
EVERY other brand failed by 10-60% (including Optima, which was one of the worst options)
