2 days is a suspect, I have no issues as long as the vehicle is driven at least one a week. However, it should be known that a race battery cannot simply be held up to the same expectations as OEM on CCA/reserve capacity.
My situation is not saying one or the other is wrong or right - just simple reference. Hope this helps.
Of course your experience is very useful. Nonetheless very strange. We have markedly different experiences with nearly identical hardware. Do you know a real expert at Braille I can ping on this? I'd like to keep the battery but not with the annoying little bugs I am experiencing.
