Then I did a load test recomended by Mex, 20 seconds at 230A and record battery voltage. Some good and bad news from the load test. The "good" side is the Duracell only dropped to 5.75V while the Trojan's dropped to 5.48V. so it would appear that the Duracell has less internal resistance, and internal resistance is a big drawback to GC batteries. But that may also be the bad news. Since both weigh virtually the same and the same AH, what magic was done to reduce internal resistance??? first thing that comes to mind is maybe thinner plates but more of them. Drops resistance, but also is a drawback to long cycle life. The battery load cell was the same as used 12years ago with the Trojans as was the NIST traceable DMM.
Time will tell
Sounds like we all have the VEC1093DBD. BFL used to have a couple of lower amp Vectors back in the day... if he doesn't still have them. And my 25A version gave up the ghost several years back.
Is that 230A at 6V or 12?
And what load tester?
