This list compares lithium and AGM batteries on cranking amps, capacity, weight and warranty, so you can match the battery to the mower and the winter.

Read the full review

12V 280CCA U1 battery with the longest stated warranty here at 15 months.
Who it's for: owners who want the longest stated warranty and full fit dimensions on the listing.
Who should skip it: anyone bothered by the 280 vs 250 CCA mismatch inside the listing.
Read the full review
The MARXON U1-280 lists 280 CCA in its title and bullets, but its spec table says 250A and names the item type u1 battery 250cca, a contradiction inside the listing; we go with the title and bullets at 280 CCA. It states dimensions of 7.68 x 4.92 x 6.14 inches, 14.1 pounds, polarity positive on the left, and a 15-month warranty, the longest stated here.

- Full fit details: dimensions, weight and polarity stated
- Maintenance-free AGM, no acid or water to add
- Names John Deere, Troy-Bilt, Toro, Cub Cadet and Craftsman fitment

Buying guide: choosing the best lawn mower battery for cold weather
Cranking amps and capacity
Cranking amps and capacity measure different things. The Mighty Max lists 400 CCA with 8 Ah, the UPLUS lists 330CCA with 25Ah, and the TYKOOL lists 140CCA with 3Ah. A high CCA figure helps turnover on a cold morning, while capacity matters for reserve power. Do not compare the two figures directly; match both to what the mower needs. For the lithium or AGM choice, see AGM vs lithium mower battery.
Lithium or AGM
Two batteries here are LiFePO4 lithium and one is sealed AGM. Lithium brings lighter weight and longer cycle life claims, while AGM brings wide tractor fit and a sealed, maintenance-free build. The TYKOOL needs a dedicated LiFePO4 charger and a qualified regulator under 15.0V, and lead-acid chargers with desulfurization or pulse modes must not be used with it. Check the charger before buying lithium.
Cold starts and winter storage
Only the UPLUS lists a cold start figure: a stated start at -22°F. The other batteries state no temperature figure, so do not assume a cold rating from the chemistry alone. For winter storage, sealed maintenance-free batteries need no water checks, and the TYKOOL listing says it maintains charge longer than a standard lead-acid battery during off-seasons. For storage help, see best battery maintainer for winter storage.
Fit, terminals and group size
Four batteries here are U1 group size, and the TYKOOL is a compact 4L-BS size for smaller equipment. Dimensions differ: the Mighty Max measures 7.75 x 5.25 x 7.25 inches and the UPLUS measures 7.68 x 4.92 x 6.93 inches, so measure the tray before ordering. Both the Mighty Max and the UPLUS list the positive terminal on the left and the negative on the right. Check polarity, group size and tray dimensions against the old battery.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- For cold starts, favor the UPLUS with its stated start at -22°F.
- For winter storage, favor sealed maintenance-free batteries and check the charge before the season.
- For small equipment, the compact TYKOOL fits where a U1 battery does not.
- For lithium, confirm a dedicated LiFePO4 charger and a qualified regulator under 15.0V.
- For fit, measure the tray and check group size, dimensions and terminal positions.
The Acre Score explained
The Acre Score weighs performance, build quality, value, safety and warranty. No listing here states a safety feature, so every battery scores zero on safety. Warranty scores reflect stated terms only.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Mighty Max ML-U1-CCALI | 9.6 | 32 | 21 | 21 | 0 | 4 |
| TYKOOL LFP4L-BS-STD | 9.4 | 26 | 20 | 19 | 0 | 2 |
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
What battery is best for cold weather starts?
The UPLUS is the only pick here with a stated cold start figure, at -22°F. The other batteries state no temperature figure, so match the CCA figure to the mower and check the manual for cold weather guidance.
Can I use a lithium battery in place of an AGM battery?
Only if the fit, voltage and charger match. The TYKOOL needs a dedicated LiFePO4 charger and a qualified regulator under 15.0V, and lead-acid chargers with desulfurization or pulse modes must not be used. Check the mower manual and the battery listing before swapping types.
What does CCA mean?
CCA is the cranking amps figure the listing states for starting power. Figures here run 140CCA, 280CCA, 320CCA, 330CCA and 400 CCA. A higher figure means stronger turnover, but match the group size and capacity to the mower as well.
How do I store a mower battery over winter?
Keep a sealed maintenance-free battery charged and stored per the listing, and check the charge before the season. For more storage help, see how to store a riding mower for winter.
What warranty do these batteries state?
The Mighty Max states a 5 Year warranty in its bullets, the UPLUS states a 15 Month Warranty, and the TYKOOL states a 1 year warranty. The two limited-data picks state no warranty term. Note the Mighty Max spec table lists 1 Year, against 5 Year in the bullets; the bullets are trusted here.
