It is important the Ecomatic is fitted with a large and good quality battery with good CCA (cold cranking amps) to ensure the [[Reinforced starter motor|starter motor] restarts the engine quickly, and reduce strain on the alternator and electrical consumers, the cost of replacing electronics damaged by voltage fluctuation far exceeds the extra for a good battery, the battery should also be able to take the strain from the large amount of engine starts.
A poorly performing battery can result in oddities with the engine restarting procedure, such as, if the engine has been off for a while, a restart can be unsuccessful or take more than one attempt.
The Ecomatic can be push started.
