Replacing the Accessory Battery on my Mercedes SL500 R230 wasn't Cheap, but it was EASY

I was getting the "Electric Consumers Offline" error on my dashboard, which usually goes away after driving for a few minutes. This time, it persisted after 30 minutes of cruising. That usually only means one thing - the accessory battery is dead.
At over $250, it's an expensive battery, but it is very easy to replace on your own.

Great video. I like your demonstrations. Often it's quicker to comprehend visually in 4k video than by text in a forum.

I agree. If it weren't for RUclips, I wouldn't know how to do most of this myself.

[@peterstokes4763]

Simple and straightforward explanation thanks.

[@rollingstocks]

Glad it helped!

Thank you 🙂 Hopefully it's helpful to other SL owners out there.

Thank-you for covering "Normalizing" the seats steering wheel and windows

Hi CJ, I keep my SL500 on a decent trickle charge.
I can run the car as normal for about a week, then simply plug in the trickle charger for a night or two (literally takes 1 minute to do).
I haven’t had one single battery problem since doing this from about 6 years ago.
Thanks for your videos 😊

There ya go! Another commentator mentioned that he has the ORIGINAL solid state accessory battery because he keeps his on a fancy trickle charger. Amazing that these batteries can last that much longer with proper care. Keep doing what you're doing!

My consumer is dying too. Think I'm going to try one of those interstate batteries also! 🤘

[@rollingstocks]

Mine is still going strong. Haven't had a consumer offline error for 3 months now, even with the car sitting for a few days every now and then.

[@sluggosloan]

@@rollingstocks I installed the same battery in mine and all good so far 👍

[@paulc9739]

Great video. Mine doesn’t say AGM.. mines a 2005… does it have to be a AGM battery

[@jgonzalesm6]

My 2009 SL550 has the original accessory battery because I have that battery on a CTEK 5.0 MXS battery tender. Car has 18k miles on it.

[@rollingstocks]

Whoa, that's gnarly! Sounds like that battery tender has got some good tech in it.
