How the heck do I replace the battery!

Ctek is a very good product. I have converted to the complete Noco Genius line and on the 5BW I have use their direct mount on board battery charger. It's permanently mounted under hood (it's designed specifically for this) so while storing I just open the hood and plug in. Its a good time to check the oil when I unplug the the cord, so I think its ideal.

Tens of thousands of Corvette owners are using the OEM maintainers

Are you saying that Blackwings are coming from the factory with built in chargers? Don

@DonD ...No, it's an option to buy the battery charger from GM, at an attractive mark up.

Built-in? No.

But you can option RPO 5WF, Battery Protection Package, which gets you a Cadillac-branded CTEK charger (Corvette has a similar option). It's expensive compared to retail prices.

I've always used the (Deltran) battery tender. I've had various models and am currently using two of the 1.25A battery tender plus units.

I have a Deltran Battery Tender Plus. Since it only provides 1.25 amps, it can take days to charge a battery enough to start the car if the battery is close to or fully drained. I know this from personal experience over the past weekend—my battery was registering 6 volts. After two days of charging with the Deltran, it still didn’t have enough juice to start the car. I ended up buying a NOCO Genius 10 from Amazon. https://www.amazon.com/dp/B07W3QT226?ref=ppx_yo2ov_dt_b_fed_asin_title

The Noco Charged the battery enough to start the car in about 2 hours. So far I'm impressed with the unit.

I just bought one of these. It's useless if the battery is close to or fully drained. It is more of a conditioner/trickle charger than a full-on battery charger. Plus the thing gets hot as hell when it's charging for an extended period of time. At $195 it is no bargain. I'm returning mine to the dealer.

I just bought the Genious 10. Very impressed with the product.

Have a 5 amp Noco coming, thanks to this thread. Don

I would install a battery tender under the hood using the remote terminal.

Can you post a picture next time you have it hooked up under the hood? I connected my NOCO smart trickle charger under the hood, using the alligator clips, checked a couple months later, and the battery was down to 50%. I then connected the NOCO directly to the battery in the trunk (that was a pain to access) and it quickly took the battery back up to 100%.... so obviously I connected something incorrectly under the hood.

I believe it's used so that your battery doesn't become "close to or fully drained". I don't know. Maybe I'm missing something?

That’s the idea, but shit happens. I’ve had the CTEKs and they work until they don’t. Now I use real equipment designed to supply the needed current. 30A for my Jeep and 15A for the 5BW. All the Amazon stuff are toys.

I agree....getting access to the trunk battery is very tight. When hooking up the quick-connect plug that came with my Schumacher, I needed to wedge a paint brush handle to keep from cutting my hands.

That clearly is its intended purpose. The problem is when the battery completely runs down after the vehicle has not been driven for 12 days, not several months of storage. That's when the thing becomes useless.

You have a different issue if the battery drains that much in 12 days.

After 4 months in storage my battery was still above 50% charge, so if yours dies after 12 days you have a parasitic draw somewhere.

Did you put the car in transport mode. Good idea for that long.

This is why my BW is currently at the dealer undergoing the 2-hour battery test.

Never heard of transport mode. Does this work for our (manual transmission) cars?:

To turn Transport Mode On/Off, start the vehicle, press the brake pedal, activate the hazard flashers, hold the start button for at least 15 seconds. Transport Mode On/Off message will display on the DIC and the Battery Warning light will flash.

Wasn't a parasitic draw. The battery had a bad cell. The dealer replaced the battery under warranty.

Just so everyone knows, the latest Cadillac battery test performed by the dealer takes 2 hours to run. I took my car in yesterday for a battery test expecting it to take under an hour. I was a bit surprised to learn it was a two-hour procedure.

I just picked up my car after being at the detailer for a week and while it started up fine, it's telling me features are reduced to save power. I guess a battery tender is in my future.
