Britax B-Safe 35 Elite — expiration
Infant car seat.
Britax ties the B-Safe 35 Elite to a 6-year useful life — the B-Safe 35 and B-Safe 35 Elite infant car seats and bases, read from their own Britax user guid.
To prevent injury due to deterioration or hidden damage, DO NOT use this infant car seat and base if it is older than six years or has been in a moderate or severe crash.

Read your label against the formula
Find the date of manufacture on the seat's label, then add 6 years — the same month. As Britax applies it:
| Manufactured in | Reaches its stated life in |
|---|---|
| 2019 | 2025 (same month as your label) |
| 2020 | 2026 (same month as your label) |
| 2021 | 2027 (same month as your label) |
| 2022 | 2028 (same month as your label) |
| 2023 | 2029 (same month as your label) |
| 2024 | 2030 (same month as your label) |
| 2025 | 2031 (same month as your label) |
| 2026 | 2032 (same month as your label) |
Where the date is on this seat
Two labels. The base carries one on its underside. The carrier carries one too — the parts diagram names it (item 19) but gives no position wording for the carrier, so only the base position is stated by Britax. The warning bullet says: "See date of manufacture located on the infant car seat and base."
