Reddit reviews Battery Tender Plus Charger and Maintainer: 12V, 1.25 Amp Powersport Battery Charger and Maintainer for Motorcycles, ATVs, UTVs, and More - Smart 12 Volt Automatic Float Chargers by Deltran - 021-0128

If there's a plug nearby, you might want to pick up a battery tender. This should monitor and keep a "float" charge on the battery.

Example: http://www.amazon.com/Deltran-Battery-Tender-021-0128-Charger/dp/B00068XCQU

There's a cheaper Jr version that might be more appropriate for you.

Also, your battery may need replacement anyway since deep discharges damage the battery chemistry.

If the battery is getting weak (especially in these colder temps), check the charging level of the alternator. If it's ok, pick up a battery charger that will automatically switch to float once reaching full charge. Throw the battery on there overnight.

Keep cold out of your gear. Like in hiking, being cold is worse than wet since it'll sap your energy. I wear a balaclava around my head and just picked up a fleece neck warmer to keep cold wind from entering my coat and helmet.

Pinlock visors are great at keeping your visor from fogging up if you wear a full face helmet.

Reflective tape on your helmet, bike and gear will add to your visibility.

Keep track of your tires and brakes. Give yourself 20 minutes to gear up and check the bike before you leave. You don't want to forget a piece of gear because you were in a rush.

Don't override your ability in lousy weather and know alternate, safer and slower routes if you need to get off the highway. It happened to me once in Skagit Valley when a rainstorm pushed me three lanes over (I shouldn't have been going so fast in the left lane) so I exited and took a really slow trip on some farming roads, then the old 99 highway all the way to Seattle.

Be aware and cautious, especially in the dark and wet around the unmindful cagers in this town, but have fun! These cold, sunny, dry days have been a blast to ride.

you got some good replies... just want to be a little more specific. something like a battery tender is good to leave connected. it will cycle on and off to keep the battery charged... Trickle chargers are manual and push a constant amount of amps until you turn them off.

the manual type are still not obsolite... for one you can charge a battery quicker because you can choose the amperage to charge at. Another benefit is if you have a very discharged battery, the newer battery tender types will not charge it because it's measuring too low of voltage and is programed to assume it's damaged... the manual type, sometimes you can set it very low and charge it up enough to switch to back to the battery tender type.

If it sits a lot then use a battery tender like this. You leave an adapter always connected to the battery then route it somewhere like the front grill. When you get home, plug it in if its going to sit a while into the adapter on the tender. That's it. It will keep it charged and ready to go. We use the smaller ones (not the one I linked) for the house generators out here and they work great. Still would be a good idea to start it and run it around the block every few months

I also have an AirSense 10 Autoset. The power "brick" provided with the unit is a conventional 120-240 VAC to DC converter. With the Ego Lawn Mower and Inverter you're converting electricity from DC to AC to DC. There will be substantial power-to-heat losses due to less-than-optimum efficiency of the power conversion.

Additionally, the AC output of the Ego Inverter (see manual, page 9) is limited to 150 Watts. At 120 Volts, this means that the current maximum it allows is 1.25 Amp. The maximum current demand that the AirSense 10 requires is 1.50 Amp. This is why the inverter's overheat is being triggered and it cuts power to your APAP; too much current is being demanded by the unit for the inverter's circuitry to handle.

I recommend following Resmed's Battery Guide using stand-alone, deep-cycle batteries.

I take my AirSense 10 camping and I recently purchased the following items, totaling to $205.56

1. $68.99 12V 35AH Group U1 Deep Cycle Scooter Battery
   
2. $11.36 Group U1 Snap-Top Battery Box
   
3. $45.03 Battery Tender Plus 1.25 Amp Battery Charger
   
4. $69.99 Rockpals DC Converter Compatible with S10 CPAP Series
   
5. $10.19 Battery Tender Female Cigarette Adaptor for Quick Disconnect
   
   12V 35AH batteries ship factory-charged. If used with tube heating and humidification switched off, and maximum IPAP pressure of 16 cm H2O then a single battery will last you for two 8-hour nights. See Page 7 of Resmed's Battery Guide for details of power consumption if using any of the heat settings.
   
   I hope this helps. Feel free to ask me questions.

Personally I’d consider selling it and get another when it’s time. Don’t you think it will sell for at least what you owe? Didn’t need payments or insurance when I helped raise my two boys, bought another later. But if you can’t decide and choose to store it, here’s an exhaustive checklist.

Here’s a great battery tender.

Congratulations and a hope all goes as planned, take care!

You should be fine. Hook it up to a battery charger though. http://www.amazon.com/Deltran-Battery-Tender-021-0128-Charger/dp/B00068XCQU/ref=sr_1_2?ie=UTF8&qid=1422682919&sr=8-2&keywords=battery+tender

Those are great to own. Really helps prolong the life of the battery.

https://www.amazon.com/Deltran-Battery-Tender-021-0128-Charger/dp/B00068XCQU

You don't need a special thing. It's just a trickle charger with constant voltage charging.

You pretty much have your question answered but I wanted to show some winter car accessories that I use and they have made life easier.

When my car is parked overnight I use a cover like this and it keeps ice and frost off your windshield. There are various types and sizes of these. Mine had side mirror pockets to hold it on and covers the wipers too. Putting in on and taking it off is much easier/quicker than defrosting and scraping.

Very cold temps can result in a dead battery, or one too weak to start the car. This happened to me yesterday and I used one of these to jump start it. I have jumper cables too, but with this I didn't need anyone's help.

When I got home, I trickle charged my battery with this. I just parked in my driveway and ran the charger's 25 foot cord under the garage door and clamped them onto the terminals under the hood. Started nicely today.

I also keep an air compressor in my car all the time. If I'm out on the road and my tire pressure sensors start beeping I can pull over anywhere and top them off.

Been using this one for a few years, I like it.

Shouldn't be a problem at all, batteries are made to be charged and discharged. Everyone should invest in a Battery Tender, they're really great chargers (and great for intelligently keeping a battery topped up for cars in storage). Not too much more expensive than shitty harbor freight ones, and they work and will last a long time.

I use this one:

But this one would probably also do the trick:

https://www.amazon.com/Battery-Tender-021-0123-Junior-Charger/dp/B000CITK8S/

Should be able to find them at your local auto parts store, or even Walmart or someplace like that.

for years.

here ya go: $30 bills

The optima suggestion isn't going to solve the battery drain issue. Yes, it's a heavier duty battery. But if you keep pouring out 1/2 cup of water out of a jug and only replace it with 1/3 cup of water, you'll eventually run out of water.

Really needs to do a battery tender and get in the habit of plugging it in when they get home. A setup like this would be a good idea. http://s279.photobucket.com/user/NotMoneyGuy/media/IMG_3749_zps1edf0d2c.jpg.html

Have a quick disconnect say dangle through the grill of the car and plug the charger in nightly.

Edit: I like the Battery Tender brand myself.

There are stupidly simple, just plug/connect them to the battery and they're automatic.

Do you have a battery trickle charger at home? I would charge the battery for ~24 hours. I have one of these, and plug my battery in once a week.

I use this one for dual batts on a Ford F350. It does very well throughout the winter.

A good battery will bounce back and give you enough juice to start. Do that enough times and the battery says "F this. I quit."

Get yourself a battery tender and leave it plugged in when not riding.

So the solution for camping and common power outages are pretty close to the same.

If you live somewhere where the power goes out often, get yourself a 12v adapter for your machine (varies by machine), buy a AGM deep cycle trolling motor battery (~$100) and a Battery Tender. Plug the battery tender to the wall, hook it to the battery, then hook the 12v adapter to your machine. Congratulations: the battery tender keeps the battery topped off, the CPAP runs off the battery, and you never miss a beat when the power goes out. If you're looking to lose power for more than one night (say you regularly have to wait out hurricanes) you'll want a bigger capacity deep cycle battery if you want to run the humidifier.

For car camping just leave the battery tender at home and turn off the humidifier. Fully charged battery should easily last you 5 nights.

If you're more of a backpacker/rough camper pick up a large USB battery pack that supports 12V out. People with Philips Respironics machines report that pack gives them 2 nights without humidifier. If you have a Philips machine it actually comes with the right size barrel plug, so no 12v adapter needed.

If you know you are going to park the bike for over a week, put the battery on a tender. If you are parking for a week, usually it ends up longer.

This may be a bad idea, but off the top of my head, maybe you could use a small inverter plus a battery tender to recreate a setup similar to your old one.

Edit: Also these are not cheap but there is a company called All In Charge that makes setups for charging your boat or RV battery while you tow.

Edit2: If these guys are still in business, they offer a solution that some people really like. Their website really needs some work though, I would bet its best to just email them.

Edit 3: Found one more solution for you from PowerStream.

Also recommend getting a Battery Tender. They're good if you leave vehicles sitting for a while, to prevent the battery from slowly discharging over time.

https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU

Here is the tender I'm using, which says it's also a charger: https://smile.amazon.com/gp/product/B00068XCQU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Should this be sufficient to charge the battery, or do you still think I should get a separate charger?

What should I be checking with a digital meter?

Here's the one I use:

"Fully Charge and Maintain a Battery at Proper Storage Voltage without the Damaging Effects Caused by Trickle Chargers"

https://www.amazon.ca/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU

Sorry to bother again... This looks reasonably convenient, is it more or less what we want?

https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU

Yeah, everyone who wants to maintain their battery (especially for storage and through cold weather) should put it on a battery tender. $40 will save you a new battery and many headaches.

Plus, you can get a usb adapter for the quick-disconenct that comes off your battery, or a voltage meter to check your battery status.

How long had it been since you last started it up?

If you're leaving it to sit for weeks at a time I would either disconnect the negative battery cable or, better yet, put a battery tinder on it to maintain the battery charge.

If the battery is running down when you leave to sit a few days then you have a parasitic draw. You can test for this but unless you are up on your electrical troubleshooting and automotive wiring it's often easier to just have an auto electric shop diagnose it for you. Old Chrysler products can be a pain in the butt when it comes to parasitic draws.

Deltran Battery Tender, that's all you need.

Verify your stator is healthy before you throw a new battery on your bike.

Do you keep the bike on a battery tender when you aren't riding it? You definitely should.

As for batteries, any AGM battery will do fine. The very best batteries are the Lithium Ion models from Shorai, but they are VERY expensive (about $150-$250), but they deliver massive cold crank amps which is exactly what you need, especially if you are trying to start a 1200 conversion with the 883 starter/gearing.

1. Verify your stator is putting out the correct volts across the entire RPM range. Your service manual will have the correct voltage values for various points in the RPM spectrum.
   
   
2. Start using a battery tender.
   
   
3. If you decide to buy a new battery, any AGM battery will be fine, but you really should consider saving up for a Shorai Lithium Ion battery, as it will meet your needs and then some. Here is a direct link to the Shorai battery for your bike: http://shoraipower.com/products?action=vehicle&type=175&make=941&model=7529&year=7529 It is $250, which I know is a lot to spend on a battery. It also puts out THREE HUNDRED AND SIXTY cold crank amps which is enough to start a big block V8.
   
   
4. Also verify the resistance of your plug wires and the health of the plug boots and the connections between the boots and the coil and the boots and the spark plugs. I doubt a hotter ignition module will do much good for you, but its possible that your current plug wires are not as good as they used to be and if the resistance is higher due to internal corrosion...that can suck away juice that should be getting to your plugs.
   
   
5. Verify your carb is healthy and in good working order. When was it last cleaned?
   
   
6. Inspect and gap your plugs, or just straight up replace them if its been more than a few years.
   
   

This so what I have: https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU/ref=mp_s_a_1_4?ie=UTF8&qid=1539529909&sr=8-4&pi=AC_SX236_SY340_QL65&keywords=battery+tender&dpPl=1&dpID=41GJoSjcVrL&ref=plSrch

Paired with this pigtail lead which sits in my glovebox: https://www.amazon.com/Battery-Tender-081-0069-6-Terminal-Disconnect/dp/B000NCOKZQ

Get yourself a Deltran battery tender

If you want to keep it permanently mounted, I would adapt influx's idea to a 120v signaling relay, that connects the wire between the tender and the battery. Plug it in, relay closes, tender gets connected. Unplug it, relay opens, tender can't pull juice.

Also, I don't know how many places you plan on charging your bike up but the Delran tenders have detachable cables. When I want to put it on the tender, I untuck the cable from the storage compartment, plug it in, and when I'm done, unplug and tuck again.

Nah it's just a standard 12V battery. You don't need a fancy tender. Anything that connects to your connector will work. And all the ones I've seen come with the pigtail so you can yank yours and install it.

I like this one because it has a few more amps for quicker charging if I'm in more of a hurry:

https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU

But any tender will do.

just put the stablizer in, close the cap, the pump your front forks up and down to mix it.

Also, buy a Batter Tender and keep it hooked up all winter (they are pretty cheap). For example: https://www.amazon.com/Battery-Tender-021-0128-Maintain-Damaging/dp/B00068XCQU/

And go out and start it up and let it run occasionally if you won't be riding it.
