The 2022 Chevy Silverado HD and 2022 GMC Sierra HD are once again available to order with the optional 730 cold-cranking amps (CCA) battery after it was removed from the two trucks’ order books due to a supply constraint.
The 730 CCA auxiliary battery is offered in conjunction with the naturally aspirated 6.6L V8 L8T gas engine in the 2022 Chevy Silverado HD and GMC Sierra HD and requires either dual alternators (RPO code KHF), or the 220-amp alternator (RPO code KW5) to equip. Pricing for the feature is set at $135.
GM removed the 730 CCA battery from the Silverado HD’s and Sierra HD’s order books earlier this month due to a supply constraint, however it has remedied the supply issues rather quickly. This optional feature is intended to provide GM full-size trucks with extra cold-weather starting power. The battery can also supply electrical power to additional equipment (such as a trailer or slide-in camper) and help maintain adequate engine cranking power for the vehicle’s main battery.
As we already know, the 2022 Chevy Silverado HD and GMC Sierra HD are offered with two powertrain options. This includes the atmospheric 6.6L V8 L8T gasoline engine, which is rated at 401 horsepower at 5,200 rpm and 464 pound-feet of torque at 4,000 rpm, and the 6.6L V8 L5P turbodiesel Duramax engine, which is rated at 445 horsepower at 2,800 rpm and 910 pound-feet of torque at 1,600 rpm. The L8T engine pairs with the GM six-speed automatic transmission, while the L5P mates to the Allison-branded GM 10-speed automatic transmission. Both pickups tap the GM T1 platform and are produced at the GM Flint plant in Michigan. The Silverado HD is also now built at the GM Oshawa plant in Ontario, however this facility does not produce the Sierra HD.

The title and first line are confusing. The normal battery is 730 CCA. What was unavailable was the optional auxiliary battery.
Also, it was mentioned on the comments on the last article on this, the optional aux battery does not aid in starting, a relay disconnects it from the normal electrical system until the engine is running. This is unlike the non-optional second battery on the diesel which does aid in starting because it is permanently paralleled with the main battery.
I’m very, very disappointed with GM, they are rendered only dark colors. This is my third High Country, one blue and the last two cherry red. My saleswoman at Nicol Auto in La Sarre Québec told me that GM no longer made Cherry Gray and Red and also no Micro Ship (puse). So I said NO THANK YOU, I don’t want any other color than Cherry Red and I kept my Sylverado Hihg Country 2018, 6.2 L which I like BUT. Since 2011 I’ve been changing my trucks every three years but this time it’s a BIG NO. I looked at you at Ford and Dodge RAM for my Cherry Red color. To bad so sad GM, you will lose a good customer, very very disappointed with you other GM… You can look in your system and you will see that I am not a liar… I would like to have a followup on my comment and I ask you to answer me ASAP…
Je suis très très désappointé de GM, ils sont rendus qu’ils ne font que des couleurs foncés. C’est mon troisième High Country, un bleue et les deux derniers rouge cerise. Ma vendeuse chez Nicol Auto de La Sarre Québec m’a dit que GM ne faisait plus de Gris et Rouge Cerise et en plus pas de Micro Ship (puse ou fusible). Alors je lui ai dit NON MERCI, je ne veux pas d’autre couleur que le Rouge Cerise et que je gardais mon Sylverado Hihg Country 2018, 6.2 L que j’aime bien MAIS. Depuis 2011 que je changeais mes camions aux trois ans mais cette fois ç’y c’est un GROS NON. Je v’ais regardé chez Ford et Dodge RAM pour ma couleur Rouge Cerise. To bad so sad GM, vous allez perdre un bon client, très très déçu de vous autres GM… Vous pouvez regardé dans votre système et vous allez voir que je ne suis pas un menteur… J’aimerais avoir un suivi de mon commentaire à GM et je vous demandes de me répondre ASAP…

Pour quoi est-ce que GM v’ont fabriqué leur modèle de camion comme le Chevy nova Montana et camion Siera au Brésil… Est-ce que c’est moins cher pour les fabriquer dans ces Pays et qu’une fois arrivé au USA/Canada vous allez nous charger plus cher à nous les consommateurs… Et le GMC Sierra Denali Ultimate’s Paldao trime en Bois (paldao bois d’arbre d’Asie), Trime extérieur comme Vader Crome, Roues de 22 pouces et composite de Boîte Cargo Gm’s CarbonPro. V’a s’envolé au U.S. du Sud Est de l’Asie. Son Prix commence à $81,790.00 U.S…. Quelle mauvaise administration de GM… Vous devriez donner l’ouvrage à nos employeurs de nos deux Pays le USA et le Canada, vous n’aidez pas à notre économies GM… Vous êtes des incompétents… Jamais que je v’ais payé un camion à $81,000.00 et +… Je ne suis pas fâché mais plutôt déçu… ☹☹
Why did GM make you their truck model like the Chevy Nova Montana and Siera truck in Brazil… Is it cheaper to make them in this country’s and once in the USA / Canada you are going to charge us consumers more… And for the 2022 GMC Sierra Denali Ultimate’s Paldao Wood (wood from a Asia Tree), exterior Trim such as Vader Chrome, 22-inch Whells and GM’s CarbonPro composite Cargo Box, is flown into U.S. from Southeast Asia, pricing starts at $81,790.00 U.S.,. What a bad GM administration… You should give the work to our employers in our two countries USA and Canada, you are not helping our GM economies… You are incompetent…
