The current CAT745 deal is on the low $$$ side for a lost certificate. The battery scheme was such that one had a better than 50/50 shot of losing the certificate using the prescribed method (even Dolby techs, in a controlled environment didn't do so well). As such, part of the fee includes a 10-year soldered in battery. Anyone thinking that they are going to get 17-25 years on a server isn't realistic to begin with...they have computer lifecycles.
I'll tell you, I'm really starting to favor the super-cap method of certificate storage. That is what has kept Enigmas and Dolby CAT862s going for a long time now. The only downside is that they presume that you actually USE your equipment. So that has to be factored into any seasonal operation (e.g. Drive Ins or Beach locations...etc.) or even the every-century pandemic. You need to get power to these devices in a regular fashion such that they run the equivalent of 3-5 days straight over 6-months.
Part of the problem I see with batteries, now that we have some long-term experience with them is, if you are a non-conventional theatre (and it has been magnified by C19), you are consuming battery life at a greater rate than the manufacturers anticipated. So you don't get your 3 or 5 or 7 years (whatever they quoted). Every hour that projector/server is off, you have consumed a portion of your battery life. So you need to have a greater frequency of battery changes. Conversely, a super-cap, it recharges up once you return to "normal" operation.
