Elevation Lab just launched a compact version of its popular TimeCapsule case that extends Apple's AirTag battery life to five years using AAA batteries instead of the standard coin cell. The $19.99 accessory addresses one of the tracking device's biggest limitations while maintaining full waterproof protection and wireless functionality.
Elevation Lab is solving one of Apple's AirTag's most annoying problems with a clever battery hack that just got more portable. The company's new compact TimeCapsule case extends your AirTag's battery life to five years - a massive improvement over the standard one-year lifespan that has users constantly swapping CR2032 coin cells.
The timing couldn't be better. As AirTags become standard gear for travelers and anyone prone to losing keys, wallets, or luggage, that annual battery replacement has become a real pain point. Elevation Lab's original TimeCapsule solved this with a bulkier design offering 10-year battery life, but the new compact version strikes a middle ground that many users will find more practical.
The engineering is straightforward but effective. Instead of relying on Apple's CR2032 coin cell, the TimeCapsule replaces it entirely with an electrical contact system that draws power from two AAA batteries housed in the case. Elevation Lab specifically recommends Energizer Ultimate Lithium AAAs to maximize that five-year lifespan while avoiding the corrosive leaks that could destroy the device after years of storage.
What makes this particularly smart is the robust build quality. The compact TimeCapsule carries forward the original's IP69 rating - that's protection against high-pressure water jets and dust ingress that goes well beyond typical waterproof claims. The fiber-reinforced polycarbonate construction ensures that Bluetooth and Ultra Wideband signals pass through unimpeded, so you won't sacrifice tracking accuracy for extended battery life.
Of course, there are trade-offs. The case increases the AirTag's weight from 0.39 ounces to 1.9 ounces with batteries installed - nearly five times heavier. That might matter if you're attaching it to keys or slipping it into a wallet. The case also muffles the AirTag's audio alerts by about one-third, which could make it harder to locate by sound in noisy environments.
But for luggage tracking, car monitoring, or any application where the AirTag will sit undisturbed for long periods, those compromises are worth it. The pricing makes the math even more compelling: at $19.99 for a single unit or $39.99 for a four-pack, you're looking at roughly $4 per year of battery life. Compare that to the hassle and cost of annual CR2032 replacements, especially when your AirTag is buried inside checked luggage or attached to gear you don't access regularly.
