I just got in the HC charger,and started it the standard way not remote, and it took a few seconds to fire up, seemed to have dry cranked, no mods all stock, what could this be?

Obviously slower than normal then? Any huge swing in ambient temperature? How old/good is the battery?

Battery is great ,it cranked very strong, I had a throttlebody cleaning done last service air filter good, seemed like a random thing because right after that I started it a few times and it was normal, it did this once before and it was sitting 10 hours that time also. No warning lights, just a very slight noticeable idle at times.i wish there was a light I would know what it is so I can correct it.

It seemed like a fuel starve issue

My 2015 does weird things at times, and I just chalk it up to the odd "glitch".

When my 2018 Hellcat was a bit reluctant to start this arose from lack of use. The battery runs down a bit. While it does crank the engine and the engine always started there is a big dip in voltage which upsets the car's electronics. Besides the slight reluctance to start often Performance Pages would refuse to load. A few times the LCD display wide vertical blue bars. Another symptom was the +paddle shifter would cause a down shift instead of an up shift.

When I took the car in for the shifter behavior the shop foreman found the car had logged several low voltage events. These were not OBD2 errors but proprietary errors.

The shop foreman had a tech apply a PCM and TCM update then when I got the car back I vowed to use it more often. The Hellcat doesn't like to sit unused for long.

Mine doesn't sit, it is my daily primary vehicle, the battery is less than 5 months old. I called dodge and they suggested installing sea foam.

How long do you drive the car after you start the engine? One of my cars was my daily driver but I only lived a mile from work...

It takes engine run time to replenish what the battery loses just sitting and what it uses to start the engine.

I had a new battery fail after 5 months. Time means everything and nothing when it comes to batteries. They can go bad after 5 months or 5 years or longer. I had one last 7 years.

Hard to believe given Dodge specifically in the manual to use no oil or fuel additives Sea Foam would be recommended by Dodge. I looked up the MSDS on Sea Foam. It is nothing special.

If you want to use a fuel additive that works use Techron. My experience is this works but the engine may not have any deposits to remove. I switched to Chevron gasoline after running Shell V-Power for a long time. One engine perked up after not even a tank of Chevron gasoline with Techron had been burned. The other engine didn't manifest any signs good or bad after switching to Chevron. The difference? The engine that perked up had several hundred thousand miles on it -- but still ran strong and didn't show any signs the miles had taken any toll -- and was N/A and used narrow band O2 sensors. The engine that didn't perk up had much lower miles, was turbo charged and used wide band O2 sensors for better fueling.

Based on my experience with my Hellcat -- which used wide band O2 sensors -- over nearly 28K miles I doubt the Charger Hellcat will benefit from Techron but you can try it.

Or just head down the freeway for 40+ miles. My experience is engines perk up noticeably from "prolonged" running at even just highway speeds. This gives the fuel detergents time to work and remove fuel system (mainly injector) and engine deposits.

Amsoil PI and upper cylinder lubricant the best you can get will keep her running clean and strong.

Very good advice

Thank you i will do that, I didn't get the seafoam, I heard its worthless. I drive 40miles 5 days a week, that is 20 miles each way to work. Everything so far is good, it just did that one time and hasn't repeated it again.
