What The Ultima ZT Needs

The Ultima ZT1 from 2019 to 2021, the ZT2 from 2019 to 2020 and the 2021 ZT3 came with part 925-1707D: a Group U1 size battery, about 7.7 x 5.2 x 7.2 inches.

From 2022 to 2025 the ZT1, ZT2 and ZT3 came with part 725P17335: a compact 12-volt AGM battery rated at 210 cold cranking amps and about 11Ah, about 5.9 x 3.4 x 4.3 inches. The ZTS1 and ZTS2, 2022 to 2024, came with the same part.

The 2021 Ultima ZT2 was built with either battery. For a 2021 ZT2, look at the battery in your mower before you order.

Cub Cadet Ultima ZT Battery FAQ

What battery does the Cub Cadet Ultima ZT take?+
The year decides. The ZT1 from 2019 to 2021, the ZT2 from 2019 to 2020 and the 2021 ZT3 take a Group U1 size battery, about 7.7 x 5.2 x 7.2 inches (part 925-1707D). From 2022 to 2025 all three take the compact battery, about 5.9 x 3.4 x 4.3 inches (part 725P17335), and so do the ZTS1 and ZTS2 from 2022 to 2024.
Which battery does a 2021 Ultima ZT2 take?+
The 2021 ZT2 was built with either battery. Look at the one in your mower: a label that reads 925-1707D is the Group U1 size, about 7.7 x 5.2 x 7.2 inches; 725P17335 is the compact one, about 5.9 x 3.4 x 4.3 inches.
Do the ZTS1 and ZTS2 take the same battery as the ZT1 and ZT2?+
From 2022 to 2024, yes: the compact part 725P17335. The steering wheel does not change the battery.
How do I check before I order?+
Read the part number on the old battery’s label, or measure it. 925-1707D is the Group U1 size, about 7.7 x 5.2 x 7.2 inches. 725P17335 is the compact battery, about 5.9 x 3.4 x 4.3 inches.
