Why remove Battery for storage?

[FrozenTows4]

Manual says to remove battery, during off season, and charge once a month. While In Season, mine is on a Deltran battery tender continually.

Since the quick connect leads are mounted permanently, why not leave the battery installed, and the tender plugged in while in storage?

I have done it both ways over the years and found no diff. My 2014 XTX spent most of the 1st season being built then rebuilt after blowup and then in for 4 warranty issues. At the end of the season I pulled it and stored it in heated shop on tender. I still had to replace it 2nd ride of this season when temp dropped to - 20 F and it froze solid!!!

I have battery tenders on all my sleds, wave runners, motorcycle and lawnmower.
I have the tenders on all year except when they are being used.
Have done this for years, and have never had to replace a battery, or not have any of them not start yet.

I never remove my batteries or charge them during the off season. But I but put them on a slow charge prior to their first start the following year. I never have battery trouble. I have a 2009 Nytro with 9500 miles on the original battery.

Same here. But I also do a deep cycle 6amp charge for about 20 min before the first ride of the season.

I also did this before a weekend ride where I knew it was going to be very cold. It was -29 deg in the morning.

I had three 4 strokes in my trailer. Mine was the only one that started. The other two had to be jumped.
And the one guy had just installed a new battery before this trip. One 1100 Cat, one 1200 doo.

If you keep a battery tender on it all summer you don't have to but you aren't then you should pull it out because the clock will drain battery down if you never charge it all summer ... It's not good on a battery if you completely discharge and leave it set ....

Same here but 2008 nytro and 15000.....just charge before the first ride and never an issue. Can't recall the battery ever out of the sled!!

I have had 4-stroke Yamahas since 2004, and have never touched a battery, except to take it out to change the oil filter. I leave the batteries in year round, and have never charged one yet. I have never had a sled not start, and that includes -35° F in canada. I have never had to replace a battery either. I think everyone us going overboard on charging your batteries.

As stated above I never pull my battery or charge it during the off season. The clock in my Viper didn't drain the battery.

Consider yourself lucky. I wouldn't say that charging batteries in the off-season on something that might only be used a few months out of the year is overkill. I don't remove my batteries but I do throw a ctec charger on overnight about once a month on any of the toys in the off season. I don't like leaving any charger hooked up all the time. I put the plug pigtails on most of the toys so it's a quick one click hookup to charge with no pulling of seats and whatnot. I've noticed since I started doing this years ago that my battery life on Motorcycles, snowmobiles, seasonal vehicles has improved a lot compared to when I would just disconnect them and charge them before the season starts. Battery's aren't cheap anymore. If I prolong the battery life another year or years doing this, then why the hell not do it. It's not time consuming.

Buddy of mine just had his shop burn about a month ago. Stored his Harley and for some reason battery shorted and caught bike on fire severely wrecked everything in there including a nice Firebird. Extremely rare I would think and even with batt out where to put battery that's safer? Something to think about though. Sure felt sorry for him.
