Should i expect lithium boost pack to open hood?

Battery died in the condo parking garage... think it's been a while so probably really dead. I haven't had any luck popping the hood with the fuse terminal using a Noco GB70 lithium boost pack. The lights on the boost pack say it's ready to go... nothing happens. I have what looks like a good ground connection at the door hinge, not the latch because the cables are too short. The jump pack has a manual mode that let's you jump batteries below 2v... I tried it in that mode too but nope. Should I expect this battery pack to open the hood? https://no.co/gb70 Do i have to leave it connected for a while before trying? I've tried the fob and the switch... i don't have to click the fob while it's in the door or something like that do i? Unfortunately there aren't any outlets in the parking garage for a trickle charge via the cigarette lighter. I tried a friends car battery pulled up along side to power the switch at the fuse... nothing still. I've since purchased a new Interstate 850CCA but don't have jumper cables to use it to power the switch. I thought the lithium pack would solve that problem but it's not working. =\ edit: have searched for cable pulls from previous owner in front right/rear left but didn't see any. Forgot to look to see if my wheel locks are on, trying to avoid pulling the right wheel well.

I latch directly to the bolt that holds the door hinge to the chassis. Have found ground placement to be little tricky...

My advice... don't waste more money on the fancy jump box since you have a brand new Interstate battery. Get some cheap jumper cables. Sit the new battery next to the door and then using the jumper cables, connect to the positive to the fuse box terminal and then the negative to the proper door hinge. And try unlocking the frunk. If that doesn't work, then no fancy jump box will. The only other option is locating the manual release cables. You could always locate the rear cable and jump from the engine compartiment.

The RAVpower lithium jump starter I bought back in 2017 is not able to open the frunk. Works great for jump starting, but something about the "smart" functionality isn't so smart.

After attaching either new battery or jump battery to fuse box posts, what method did you use to open frunk, key fob or frunk release beside seat?

Hmm, seems I can’t read today. Sorry for question. I’m no help.

Well, i hooked the new battery up to the fuse terminal with proper jumpers as suggested and as soon as i touched the latch the alarm went off and the hood popped with the fob. There was no messing around with the leads, just bang on immediately. Out of curiosity I tried jumping the dead battery with the litium pack. At first it wouldn't go because of the shut-off feature when the battery is below 2v, but when I bypassed that she fired right up on the first crank. Love this car haha. So, it looks like the lithium packs cannot be trusted to open the hood... but they work fine for to start the car (the Noco GB70 at least). So i'll keep it under the seat. Now it's just a simple matter of avoiding this in the future by keeping the battery charged when i go away. I don't suppose letting it go dead and jumping it everytime i get back is too healthy for the battery. Antigravity kinda pricey. Parking garage = no solar charger. Maybe i just pull the battery and trickle charge where there's an outlet (ie. up in my unit)... seems like the remaining option. Or i could just move, anyone notice downtowns are kinda empty these days? =] thanks for all the helps

First and foremost you need to locate the frunk lid emergency release cable and relocate it to just inside the tow hook plug. Think of how simple this would have been, dead battery, pop out the tow hook plug and easily open the frunk lid by one simple pull. Full access to battery. Also, when parking for an extended period of time in your condo garage, pop the frunk and leave it.

I have opened my frunk with my Noco GB40 before to see if it would work. Actually the frunk was opened at the time, but I closed the latch and it reopened. I put the instructions on my Noco so I’d remember the correct sequence:

I have a DBPower jump start battery, and the only intelligence it seems to have is a button you must press that activates the battery for 10-seconds. I used it to power an electric motor, so I know it doesn�t check existing battery health, and instead, just works. Amazon Amazon

Hmmmmm, interesting. I did that exact process written in your note... maybe it really is super sensitive to the clamp. For interest's sake maybe I'll clean the hinge nut and fuse terminal and try the lithium pack again just to see what happens. If it works for yours... Thanks for the feedback, and good idea with the note!

Yay! You took my advice and used the new Interstate battery. IMHO, alot of those fancy little jump boxes don't provide the necessary current to do the job right. Anyway, congrats and hope you enjoy that car!

Damn, Tex, you made my day! With the passage of time, I find it increasingly useful to snap pictures and make notes of stuff. The wife pitches in on more involved projects by bagging & labeling bolts, screws and small bits. The neighbors' cat usually cruises by and handles inspection and quality control. It's all good.

I could not get a good ground on the door latch. But getting into the engine bay for a jump worked like a charm.

What is the manual override button?

The manual override is the button on the front.

Oh, the button on the jump battery, got it!

You guys should also realize the NOCO GB40 has a very small Battery in it... But our Antigravity XP-10 would do it with no sweat at all. We actually make a kit for allowing you to open your frunk of Jump Start your car if you get locked out. Its compromised of a harness kit you plug the Jump Starter into.... But then again we make a Battery with Built-In Wireless Jump Starting so you would never need to Jump Start your Car again. This is the wiring Harness... you can use it with most Jump Starters like our MICRO-START Model XP10 or other brands. https://antigravitybatteries.com/pro...s-msa10b-long/ XP-10 Antigravity Jump Starter- " Consumer Report "Best Rated Jump Starter..." https://antigravitybatteries.com/pro...s-msa10b-long/ Anyway it give power directly to the battery terminals so you have the energy to pop the hood easy or jump start it. And yes the depending on the model of Mini Jump Starters and the internal Battery size they will easily supply enough current to pop the hood on a Porsche. But it is often harder to get a good connection on fuse panel and a good ground. Also several of the MIni Jump Starters won't turn on if they don't see voltage as a safety precaution.
