Which EGO batteries fit which mowers?

EGO says its 56V ARC Lithium batteries work across EGO tools and chargers. The battery supplied with a mower kit is a separate question: here is the pack EGO lists for each model.

Compatibility matrix

Battery fit and the pack included with each mower kit

“Compatible pack” follows EGO’s 56V ARC Lithium platform statement. “Included” identifies the battery configuration EGO lists for the named SKU, not a minimum pack size for every lawn.

What compatibility does not tell you

Fit is not the same as a good runtime or weight match

A 5Ah pack is platform-compatible with the LM2135SP, but EGO lists a 7.5Ah battery in that kit and bases its up-to-60-minute claim on the recommended 7.5Ah pack. A smaller or larger battery changes capacity and weight; it does not guarantee a fixed mowing time. Grass condition, blade mode, battery charge, and use affect the result.

For kit contents, use the model-by-model kit table. For charging time by battery and charger, see the EGO charging chart. Compare deck and cut system in the EGO mower model comparison.
