My final set of batteries with the gen 2 battery cover lasted 65 hours. I got around to installing the gen 3 covers and the 1st set of batteries for V3 lasted 7 hours before low battery warning. 2nd set lasted 10 hours. I got out a multimeter and found the left pedal battery voltages were 1.294/1.287V and the right were 1.591/1.590V. The previous batteries I removed were 1.281/1.287V on left and 1.590V for both on the right. I cleaned the terminals and put the old right batteries back on the right side and fresh (1.642/1.643V) batteries on the left. We shall see if maybe I have an issue on the left side or if I may have put weak batteries on the left. I store my spare batteries in the freezer. I have been using Energizer 357 batteries. Rides have all been indoors, and pedals are connected to an Edge 1030.
Did you buy the batteries from a reputable supplier that has plenty of turnover so the batteries are fresh. Worst mistake i made was to buy some from the internet that didn’t last long and turned out to be fake. If they are cheap there is a reason. I store mine at room temperature and they are fine.

I bought them at a local Walmart or Walgreens. Not sure which, as I have bought from both. I'm going to be keeping track of the voltage for my new batteries from now on and the voltage of the used ones.
Should be ok.
I get about 140 to 150hrs but I use Duracell 1/3N batteries which are Lithium rather than the LR44.

Lithium primary cells have very low self-discharge and thus very long shelf life. And they come with an “expiration” or “best-by” date. At least the name brands (non-counterfeit) do.
E.g., in early Aug this year (2020), I restocked my 1/3N cells. Every one bore the “best before” date of Mar, 2029.
So, yeah, counterfeit cells will likely die young. But the real thing last literally years and years on the shelf. I can’t imagine a reputable distributor or reseller that would maintain inventory for the better part of a decade.
That’s why I stock up rather than buy strictly as-needed.
The big Varta CR1/3N are the Hammer, more then a half year to replace the batteries and never had a prob during my rides with them!
I put new Maxell LR44's into my Vector 3 pedals in November, 2020. I upgraded the battery doors at that time. Cycling dynamics is always on.
I rode a bit over 34 hours with them before the bike went for a checkup. The local bike shop is quite busy, so I only got the bike back this February. I rode another 52+ hours, including 9 - 10 hours after the first low battery warning, for a total of 87 hours. That's the best I've done on these pedals so far.
I still have more than 30 of this batch of LR44 batteries left, so I won't be able to try the high capacity batteries for a while.
