How many days until battery discharge when rocket3R is not in use

[Mighty Mouse]

I have always used a battery tender. If I ride my Rocket one day the next morning it's on a tender until I ride it again. Even if I ride it later in the week I use the tender in between. I mean, why not?

I go buy the recommendations I've known from battery manufacturers for the past 45 some odd years, every month if I don't use it, but over the winter I use a trickle charge, be careful of overcharging too, most chargers are automatic today. If the battery was dead, totally discharged for a month, forget it get a new one, it's toast.
Charge more often in extreme high or low temperature.
How many amps is your bike drawing just sitting key off, no lights on?? Shouldn't even be an amp, should be about 250ma. For the clock.
If it's over that something is shorting out, read how to find shorts, I would start by ungrounding the starter, then the alternator, if you don't know anything about electricity, it will be cheaper to have someone who knows what they are doing, you can really do some damage just by not disconnecting the battery before doing anything.

I try not to go more than a couple of months between charges in the winter, never had issues with the battery and it always starts when I need it. They can go a long time before they need charged.

My experience , even with a new battery is 30 to 45 days .

I don't see why you would not put a bike on a tender if not used over a winter season. I keep all mine connected if not riding weekly. Since I have a few bikes it might be a couple of weeks to a month before one gets riding time. All the new machines, cars, trucks and bike have parasitic draw for various functions. Some models fare worse than others.

My 221 came with the standard pigtail for a battery tender attached (see below). I connect the tender whenever I know that I won’t be riding for a few days or longer due to weather. I’ve done that with all of my bikes.

You probably already know this Ice but like you I have my 'pigtail' go under the seat. I have it come up under the passenger peg and is hidden when the pegs are up. I give it just enough room that when the pegs are down it won't leave the area and interfere with the passengers feet. I give it just enough room to stay in place but easy to charge. Cheers.

Good idea, I moved mine under the passenger peg so it’s hidden now.
My first spray wash after 1,700-miles. I put a plastic bag over the TFT before spraying. Then I avoided the handlebar switches and air intakes.

Hi,

can someone tell me how long it takes until battery discharges to the point where it only turns on INSTRUMENT DASH but does not kick the starter motor ( battery voltage goes around 8V as compare to 13V ) when the bike is not in use at all?

10days? 20days? 40days?

Thankyou

I did electronics measurement and battery drain calculation for rocket3R 2022 - Battery, Turn signals

Hello All, Hope it helps someone - Stock blinkers are 2watts 12V LED Array in each blinker/turn signal so they are consuming 167Milliamps per blinker. - When bike is completely OFF and Key Fob is ON and in range then motorcycle drains battery at 80Milliamps. - When bike is completely OFF and...

Buy a battery tender and leave the bike hooked up to it when you're not using it. They come with a lead that you bolt to the battery terminals, leaving a tail hanging out the side of the seat or wherever. You plug easily into that. You'll double or more your battery life doing this. You'll kill your battery letting it go flat often.
