 +It's not foolproof, but seeing a CCA (Cold Cranking Amps) spec listed on the battery suggests it is //not// a deep cycle battery: 
 +
 +> While it might be tempting to estimate the AH rating of a battery from its CCA rating, there is not a simple relationship between these two battery parameters.((https://www.mathscinotes.com/2016/12/relationship-between-battery-cold-cranking-amps-versus-capacity/))

 Having said that, if one is aware of the limitations of the battery it can play a role in the campervan, particularly as a "learner battery" that the [[electrical:batterycide|beginner often murders]].  Lifespan on these batteries can be maximized by cycling lightly, perhaps 20% [[electrical:depth_of_discharge|depth of discharge]]. Having said that, if one is aware of the limitations of the battery it can play a role in the campervan, particularly as a "learner battery" that the [[electrical:batterycide|beginner often murders]].  Lifespan on these batteries can be maximized by cycling lightly, perhaps 20% [[electrical:depth_of_discharge|depth of discharge]].
