A good comparison is to space rockets... For example the recent SLS that flew for the first time last year, which had been delayed, and delayed more, and more... AFTER it had been slated to launch, where the Solid Rocket boosters had been poured years prior. They watched as the time span for their shelf "Best Used By" date elapsed, and NASA had to assess and recertify that they'd be OK... three times! (or was it more; hard to keep track)
THEN after it finally got stacked, they're were more delays, totaling WELL over a month... It had a dozen+ payloads which had batteries, none of which had any way to recharge them without de-stacking the thing. Some were just NASA payloads (the Artemis module), but others were this party customers.
It finally launched and while the solid rocket boosters did just fine, and Artemis did its thing... half of more of those other payloads either failed completely, or partially, due to batteries. And these weren't sitting on shelfs for a decade! Only that time since it was stacked!
But yea, batteries are the easy things to replace. Solid rocket motors might be as well, but, they're much more expensive...
