AirTag Hardware Options: Pick the Right Form Factor

Standard tag

The Standard TagLogger tag: $15 one-time hardware. Small coin-sized disk, about 1.26 inches across, around 0.4 ounces. Runs a user-replaceable CR2032 coin cell for roughly a year. IP67-rated, so dust-tight and splash-safe but not built to live underwater or get pressure-washed. Uses the Find My network for location reporting — no cellular SIM, no per-device connectivity fees.

Best for: indoor or protected placements where the small footprint matters more than weather-hardening. Tool cases. Gangboxes. IT hardware. Shared shop equipment. Flight cases with an internal mount. Basically anything where the tag lives inside another container that's already doing the protecting.

Not ideal for: direct outdoor mounting in sustained weather, anything with constant heavy vibration, or fleets large enough that annual battery swaps across every tag would eat real time.

Magnetic holder tag

The Magnetic Holder option: $21 one-time hardware for the tag-in-holder bundle. Standard TagLogger tag inside a weatherproof magnetic holder that adds a strong neodymium magnet for attaching to any clean steel surface, additional weather protection for outdoor use, and impact protection beyond the bare tag.

Best for: outdoor mounting on vehicles, trailers, containers, and steel equipment. Quick to install (no screws, no adhesive curing time), and easy to relocate when an asset changes purpose.

Not ideal for: non-magnetic surfaces (plastic, aluminum, wood) where the holder has nothing to attach to, or for fleet-wide deployments where annual CR2032 swaps are too much maintenance.

Extended Battery Case tag

The Extended Battery Case option: $45 one-time hardware. Tag circuitry mounted inside a ruggedized case powered by two installed AA lithium batteries instead of a CR2032. Rated for up to ~10 years of battery life.

Best for: fleet assets where battery maintenance is the limiting factor — trailers, containers, rental fleets, outdoor equipment, remote monitoring. Also the right choice for cold-climate deployments where CR2032 chemistry struggles but AA cells perform better.

Not ideal for: assets where a compact form factor matters (the case is larger than the bare tag) or where the asset's value doesn't justify the higher per-unit hardware cost versus the Standard or Magnetic options.

Picking the right hardware per asset category

Cost comparison across form factors

Standard tag: $15 one-time hardware. Annual CR2032 replacement: ~$1–$5 per tag per year. Service runs $10/tag/mo at entry, falling to $7.50/tag/mo at 80+ tags (5% annual-billing discount on top).

Magnetic Holder tag: $21 one-time hardware for the tag-in-holder bundle. Same CR2032 battery cycle and same per-tag monthly service as the Standard.

Extended Battery Case tag: $45 one-time hardware. No CR2032 replacement for up to ~10 years (only periodic AA checks). Same per-tag monthly service tier as every other tag.

At fleet scale, the Extended Battery Case often works out cheaper over 5 years than the Standard due to eliminated battery-swap labor cost — for 200 outdoor tags, eliminating 200 annual battery swaps saves significant maintenance time. Service pricing is tier-based on total tag count, so the form-factor mix does not change the monthly service rate. See /#pricing for the live volume tiers and annual discount.

Battery chemistry differences

CR2032 (Standard AirTag): Lithium coin-cell. Widely available, inexpensive, short installation cycle. Capacity drops in extreme cold. Best for temperate indoor and moderate outdoor use.

AA Lithium (Extended Battery Case): Higher capacity than CR2032, better cold-weather performance, longer shelf life. More expensive per cell but replaced 10x less often.

For cold-climate fleets (construction in winter, outdoor storage in cold regions, refrigeration tracking), Extended Battery Case is often a significantly more reliable choice even before counting the fleet-scale labor savings.

Mixed-hardware deployments are normal

Most TagLogger deployments use a mix of hardware options — not a single form factor across the whole fleet. A common pattern:

• Standard AirTags for the indoor/protected tools and equipment (the majority of asset count).
• Magnetic Holders for vehicles and trailers that need quick outdoor mounts.
• Extended Battery Cases for the 20–30% of outdoor or long-cycle assets where 10-year battery life saves maintenance overhead.

TagLogger's platform handles mixed hardware seamlessly — every tagged asset shows up the same way in the map and history, regardless of which physical form factor the AirTag is in.
