I just put a brand new motobatt battery in my 650 about 3 weeks ago. I have a shark 600 watt system on the scoot.
Without any lights on, or trunk light on, I went out to take the scoot to work the other day and the battery was totally dead. I mean totally.
I haven't ridden the scoot since I put the new battery in, but I've started it a few times.
Now, in wondering, is the shark system drawing power from the battery, enough to drain it, even when it is off and the bike sits for weeks at a time?
I put the charger on it last night, and after about three hours on the charger, there finally was enough juice in the battery to start the bike.
Anyone else experience this issue?
I had this dead battery issue last fall, but at that time I chalked it up to the battery being old and tired.

Yes.
My MotoBatt was dying from me LED Key fob sensor (low amp drain) after a week of being idol.
As long as you crank it up every 3-4 days and let it run for 10 minutes or tender it then it should be fine.
My OEM never did that to me over the 8 years I had it.

I have had an AM/FM/CD player automotive stereo package
on my '05-400 since 2 months after I got it in June of '05.
The memory circuit of the stereo has a constant trickle
drain in the battery, to maintain the memory.
Since we only have a 10AH battery to start with, any
continuous current draw will run down a battery soon.
How soon ?? In my case, about 4 days...dash display
will still read, but it won't start. By 7 days...there's nothing.
So....since the other side of the glove box has a space
big enough for a half gallon of milk, or a 2 liter soda
bottle, it's also big enough for a second battery...mine
is wired in parallel. Slightly longer bolts in the terminals
of the original battery give enough space for a second
set of lugs for the additional wiring. The second battery
has the polarized pigtail wire for my Battery Tender...
it charges both batteries at the same time.
My pair of batteries are a matched pair...purchased
& installed the same day....the factory original battery
was failing at 10 months..the dealer replaced it...
I paid for the second battery. No issues since then.

it just seems funny that when I don't have the shark unit plugged in, the battery will hold power for months.
I hate to keep it unplugged when not in use as it loses it's memory of what song I was listening to.

 

[cactuspwr]

Yep That's a fact. Same problem can happen on a modern car. You have to run the engine every 3-4 days to keep the battery charged.

On my side I use a relay to cut the power to my shark system.

I have had 2 shark audio units and have hooked both to an aux power so it will only turn on when I have the switch on... no drain... works for me...

 

[wilder days]

Great idea Russl. I may do that hookup. I just hate the thought of losing the "memory" every time I power down the scoot. Then have to jump to new songs each time I ride again or listen to the same ones over and over ...:-(...aarrggg
If the **** radio got better reception, I'd use that more often instead of my usb stick with all my favorites.

I have a regular car radio in mine and I just hook the Burgman to the battery tender when its in the garage, never had a problem.

I just hate the thought of losing the "memory" every time I power down the scoot.

The only thing that keeps that 'memory' working,
is constant voltage from the battery.
