| Some manufacturers attempt to get around the [[electrical:12v:psoc|Partial State of Charge]] limitations of lead chemistries by using carbon in some form.

The idea is that the addition of carbon increases the internal conductivity of the negative plate under challenging conditions, minimizing hard sulfation that can form in PSOC scenarios. |

| In the milder form, carbon is added to the negative plates. Trojan claims up to 15% more cycles from the RE(("Renewable Energy")) line than non-carbon FLA in PSOC use.((http://www.trojanbattery.com/new-products/smart-carbon/)) At this writing the cost premium for this <=15% increase in cycles is 21%.(($175 for T-105RE vs $145 for T-105)) | In the milder form, carbon is added to the negative plates: |

| | > Battery manufacturers have begun including high purity conductive graphite in the negative active material of their batteries. They have found that this type of carbon helps to maintain the essential active material conductivity that helps to control sulfation.((https://batteryvitamin.net/sulfation_remedies_demystified)) |

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.

| | It's not foolproof, but seeing a CCA (Cold Cranking Amps) spec listed on the battery suggests it is //not// a deep cycle battery: |

| 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]].
