Verdict: Choose AGM if you want a sealed lead-acid battery; the Mighty Max 320 example offers a long compatibility list, while the Mighty Max 200 example offers 35 amp_hours. Choose lithium if you want the higher CCA example, a stated cycle-life rating and a built-in display, and your charging system stays within the stated range.
A mower that will not start usually points at the battery, and agm vs lithium mower battery comes down to chemistry, cranking power and what each listing actually states. This comparison covers the differences, then examples of each side from the listings.

Figures are manufacturer stated for the example models, collected 25 October 2026.
Cranking power: CCA on both sides
CCA figures are stated on all three listings. The Mighty Max 320 example states 320 CCA, the Mighty Max 200 example states 200 CCA, and the TYKOOL lithium example states 480A CCA. The TYKOOL example states the highest CCA figure of the three, while the two AGM examples cover a lower and a mid-range CCA figure for different mower needs.
Capacity and cycle life
Capacity is stated clearly on two listings. The Mighty Max 200 listing states 35 amp_hours, and the TYKOOL listing states 12 amp_hours. The Mighty Max 320 spec table lists battery capacity as 320 amp_hours, the same figure as the 320 CCA in its title, so that listing leaves capacity unclear rather than stating it. Cycle life is stated only on the TYKOOL listing, at over 3,000 cycles, while neither AGM listing states a cycle count, so the AGM side leaves cycle life unclear rather than losing on it.
Weight and size
Weights are stated in different units, so compare the listing figures as stated. The Mighty Max 320 example weighs 14.1 pounds, the Mighty Max 200 example weighs 12.9 pounds, and the TYKOOL example weighs 2300 g. Sizes are close: both AGM examples measure 7.75 x 5.11 x 6.25 inches, and the TYKOOL example measures 7.6 x 4.8 x 6.9 inches, with a tray check of approximately 7.6 x 4.8 inches stated on its listing.
Protection and upkeep
Protection claims differ by side. The Mighty Max 320 listing describes a spill-proof SLA/AGM battery that mounts in any position and resists shocks and vibration, with high discharge rate and deep discharge recovery. The TYKOOL listing describes a Smart BMS with 5-layer protection, an IP66-rated waterproof housing, a V0-rated enclosure and a built-in display showing voltage and energy levels, with zero maintenance described. The Mighty Max 200 listing states no protection features.
Fit and compatibility
Compatibility differs by listing. The Mighty Max 320 listing names Craftsman, Cub Cadet, Husqvarna, Toro, John Deere and other ride-on mowers. The Mighty Max 200 listing states no compatibility list. The TYKOOL listing states a drop-in replacement for 725-1707D and BCI Group U1, replaces U1-9, U1-7 and U1-5, and is not suitable for 725-17335. The TYKOOL listing also states a charging requirement: mowers with regulated charging systems with alternator output between 13.8V and 14.6V.

The Acre Score explained
The Acre Score weighs five factors: performance (CCA, capacity and starting power), build quality (housing, terminals and protection), value (what comes in the box), safety (certifications or operator controls the listing states) and warranty (years and coverage). A factor the listing does not state scores zero, which is why the Mighty Max 200 example scores zero for safety.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| TYKOOL 480 Lithium | 9.7 | 32 | 21 | 20 | 8 | 3 |
| Mighty Max 320 AGM | 9.6 | 29 | 20 | 20 | 5 | 3 |
| Mighty Max 200 AGM | 9.4 | 26 | 19 | 20 | 0 | 3 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

FAQ: mowing large lots
Can a lithium battery replace an AGM battery in a mower?
The TYKOOL listing states a drop-in replacement for 725-1707D and BCI Group U1, but not for 725-17335. Check the battery tray size of approximately 7.6 x 4.8 inches and an alternator output between 13.8V and 14.6V before buying.
What does CCA mean on these listings?
CCA stands for Cold Cranking Amps, the starting-power figure each listing states. The examples state 320 CCA, 200 CCA and 480A CCA, so compare the stated figure for the mower, not a category rule.
Do AGM batteries need maintenance?
The Mighty Max 320 listing describes a spill-proof battery that mounts in any position and resists shocks and vibration, and both AGM listings state rechargeable batteries. Neither AGM listing states a maintenance schedule, while the TYKOOL listing describes zero maintenance.
How long does the lithium example last?
The TYKOOL listing rates the battery at over 3,000 cycles. Neither AGM listing states a cycle count, so the AGM side leaves cycle life unclear.
Does the lithium battery need a special charger?
The TYKOOL listing states it maintains charge for months without a battery tender, and requires a regulated charging system with alternator output between 13.8V and 14.6V for BMS compatibility.
