Electronics » Computer preset saver gadget

For bikes (or cars) that have a computer with presets that you want to save when your remove or replace a vehicle's battery, this 9V-powered "battery memory saver" looks useful. Not only is it cheap, but it also would make a good Christmas "stocking stuffier": https://www.amazon.com/dp/B07BLQ9WSS?ref..._asin_title_0_1

Of course you will need an SAE/car-cigarette lighter adapter, but those are easy enough to source. I think I have several in my collection of 12V electrical adapters.

This will only work if your outlet is hot all the time. It won't work on a BMW.

But it is good for your brain to periodically go through the process of re-configuring all your bikes set up in the menus.

Don’t know if that’s really needed. My truck is a 1998. I leave the battery disconnected when not in use. All I lose is the time setting and the radio turns on to AM, but all the presets are there. If those could eventually pass, I suspect it’s when a built in capacitor totally depletes and dumps the memory. Same deal with my Prius when I disconnected the batteries.

The BMW only has the time/date reset, and since it’s set to sync with the GPS, it’s easy to correct. All other settings are programmable non-volatile memory.

My 1999 Saturn looses the time and radio presets if I disconnect the battery for even a few seconds. I have no idea if it also looses the CPU's driving parameters, as I am not even sure if it has any. Anyway, this device does make a cheap gift for anyone who has had this sort of issue before with their car or motorcycle.

What brought this to my attention were complaints on the F800 forum that when the battery is removed for some reason, owners were loosing some of their display functions, such as the time, and were also getting the dreaded "service required" warning that you need a GS-911, Motoscan, or a trip to the dealer to reset.
