Hello, new to forum
I don't really do small talk so straight down to a question
This will sound crazy, I know I know the answer to this, but car batteries scare the hell out of me ever since one exploded on me 6 years ago (father in law overcharged it).
I'm putting a new battery into my car, it's 12v 53Ah standard wet cell car battery.
To prevent me losing my radio (I don't have the security code), I was thinking about connecting a 12v 1.2Ah SLA battery from a little project i've been working on, in parallel with the old car battery before removing it, then connecting the new battery before removing the little SLA.
The other reason for this is that GM saw fit to have my car flash it's headlights when the battery is reconnected, which at 2x55w causes some serious sparkage whilst trying to twist and tighten the terminal clamps. So i'd be quite happy to trick the car into thinking nothing has happened.
12.8v car battery and a 12.68v SLA, both fully charged.
I strongly doubt anything is going to go bang, but i'm also wondering if I should play safe and wire in one of my 2.2ohm 100w resistors just to limit the current to/from the SLA to a maximum of around 5.5A.
What would you do?
