 > Each manufacturer also has their own in-house brand, e.g. Delco for Johnson Controls and Deka for East Penn. Exide and US Battery use their corporate name for their battery brand as well. Trojan sells under the Trojan, Trillium, Reliant and Ranger brand names and Concorde sells under the Concorde and Lifeline brand names.... [Interstate is a label, not a manufacturer]... ​ The 4 big US battery makers offer a couple price and quality tiers for their customers to choose from, but generally batteries with the same specs (AH/RC, CCA, and BCI case size) will be essentially identical. Warranty, MSRP, etc. is set by the selling brand and may differ, but the physical product is the same. -- Gary RVRoamer((https://​www.irv2.com/​forums/​f59/​trojan-t-105-or-interstate-again-486470-2.html#​post5246144)) > Each manufacturer also has their own in-house brand, e.g. Delco for Johnson Controls and Deka for East Penn.

 +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]].
