Question Alarm Back-Up Battery 2006 LT

Anyone have any information on this little critter ?

A little background.
Have extended periods away from our bike between riding seasons. Around 8 months longest so far.
Do the long term storage preparations including disconnecting the battery earth ( No mains power available )
Alarm has always remembered previous mode. Which is good. :-)
Central locking and alarm NOT SET during storage, prior to battery disconnect.

Very long absence this time, over 2 years. :-( Got me thinking about the back-up battery in the alarm.
Maybe it's kept charged when connected to the bikes battery as in normal operations.
Or perhaps it's independent from the bikes electrics, just there to hold the mode setting in memory between battery changes.
As above, was fine even after 8 months, but it's getting older and as we know batteries don't last for ever.

Just wondering.

Cheers

Hilton, you should see a number of settings on your LCD display that are maintained after the battery is disconnected.

The on-board computer retains various settings just like a flash drive, which doesn't require power either for long term memory storage.

Thanks Bob.

I can understand the similarities to flash drives for ECU 's etc.

But the alarm system is available as an accessory and IIRC
when armed, will power its own horn when activated - even if the bike battery is disconnected.
That means it would probably have its own battery within the module.
Even after lengthy storage my alarm has retained a memory of the mode setting. That could be similar to the flash drive, i.e. a non-volatile memory: but to power a horn will require a battery.
That's the battery I'm looking for information on.
Thanks for your input.

Cheers

Yes the alarm has only one internal independent battery. This battery charges from the bikes system and a 2 year period with the bike battery disconnected could result in a dead alarm battery. But the best case would be a default to immobilizer on when you hook up the battery. Worst case would be a non functioning alarm, and in that case you would need to bypass it with two jumpers.

Re: Alarm Back-Up Battery 2006 LT

Thanks John.
As I thought, charged up by the bikes system.
May alter my initial maintenance actions.
Before replacing the bikes battery to bleed the wheel circuits using the ABS,
might be a good idea to have easy access to the multi pin connector for the alarm. If it starts screeching after I connect I can disconnect quickly.
Oh and I can have the bypass proceedure handy too.
Thanks for that info.
Cheers
