Is it okay to use a 1.25A Battery Tender on this LiFePo battery during Winter storage of my motorcycle?

You will need to call Battery Tender for specific info. They will point you to the best Tender for the job. I have been using Battery Tenders for over 18 years. First one I had lasted 13 years. They are great. I own a Motorcycle Training Site and have 20 Motorcycles. These Tenders are the ONLY way to go.

Charge it before storage & charge it a couple days before use , this kind of battery doesn't require to be charged all winter long.

you will not need even with a small drain transponder key clock etc start 1 a month if ya cannot wait till about three days fore opening bike for season bring it up to green light and remove i drive in extreme cold and stored covered in carport in cold i put ceramic heater under cover switch for outlet is in kitchen i switch on heater 30 min before start time this brings under cover temps to just over 80 degrees . bike spins over like a 80 degree day

The main thing is to avoid using a charger with a desulfation mode, which can destroy a lithium battery. From the BT documentation:"As long as the battery charger does not have a desulfation mode and the peak voltage does not exceed 14.8V during the charge cycle it, can be used to charge a Battery Tender® Lithium Battery."I use a trickle charger to take the battery to a full charge, then immediately disconnect. Because of the low self-discharge rate of a lithium battery, there is no need to leave a Lithium ion battery on a trickle charger for an extended period of time. full charge.

Yes, but there is a specific charger that goes with it, and they are not interchangeable.

No, this type of battery prefers not to be trickle charged. it is a different chemical than the standard lead acid battery therefore trickle charging is not only not necessary, but it may damage this type of battery since it is lithium based. This battery will hold it's charge for at least a full year without trickle charging.

I keep my bike on a Battery Tender whenever my bike is not in use. I checked that lithium batteries were compatible with these kinds of chargers and what better compatibility then using a charger by the same company.

Should be no problem. I have the Battery Tender Junior .75A charger and the folks at BT said it would be fine. Since I live in Texas I get to ride a lot during the winter but those days or weeks when I can't, it works fine. If you want to be sure just call the folks at BT (Battery Tender).

Although there is some confusion in the information on LiFePo batteries, the instructions with this battery says you can use this kind of charger to charge battery. There is no information on using the charger for winter storage. Although the battery is supposed to retain a charge for a year w/o use, I have kept it plugged in to my battery tender w/o any apparent consequences. Some reviews say that this type of battery does not like "ghost voltage" which may drain the battery (my bike's computer does not seem to have enough draw to impact charge). Overall, the major problem with this battery is that it does not tolerate cold temperatures as well as a normal battery. It has been suggested to me by a service manager that I should warm the battery by turning the ignition and lights on prior to early morning start. It does seem sluggish when starting the first thing in the morning. This seems to help. Battery Tender makes a charger for the LiFePo but will not be available until early summer. Hope this helps.

I own 3 battery tender pluses for the cars I put in winter storage. These work so well I would hate to recommend battery tender junior. However, I am sure all battery tender products work great.

I live in northern NJ, where the winter temps range in the teens to low 20's. The tenders have kept my batteries fines for years. A college buddy lives near Fairbanks Alaska. He keeps his cars on tenders through each winter night to prevent the battery from freezing or going down. In the morning, he disconnects, drives to work, and then attaches again at their special parking lots. They are designed for heater and battery plug-ins.

No. Must use a non-desulfating type battery charger. I have a lithium battery on my bike - I use a standard Battery Tender - has been working great for almost a year.

the best way to get an answer to this question is to go to the battery tender site and they will be able to give you a correct answer

I am not sure that the Battery Tender Junior has the sophisticated electronics that the 4 up Battery Tender Plus does. I have been able to keep 4 ea. 27 size deep cycle batteries at maximum voltage and CCA for two years since I got my 4 up unit. I believe that the Battery Tender Juniors are designed more for smaller batteries. You would have to talk to the people at Deltran for a more detailed answer to your question as I am not an electrical engineer. I really like my 4 up unit.

Not sure, I would contact Battery Tender Company,I'm sure they could advise you.

It works just like the factory battery. No problems at and fits great. Plus you can't beat the price. Great buy. I don't know why it failed on you unless you kept it stored ina hot place or cold batteries need to be pretty stable temps because they take a lose of power when this happens and it can ruin the battery. I have had this happen to me with 3 batteries in my garage. I live in a cold climate and i decided to move my Makita kit to the basement my batteries last allot longer now, and I fixed the problem. I hope this helps you. same thing goes with my motorcycle. I have to keep a battery trickler on it to keep it warm and small amount of power going into it during the winter or I will loose it. K take care, and I hope I have helped you out.

no. you don't really need one on lifep04 because of the voltage vs.capacity curve. especially since it's meant for a starting application. I installed this batery on my 08 ninja 250, it works great and is incredibly light weight.

I read that a Battery Tender (brand) charger is compatible with Shorai batteries and have been using one on 3 different motorcycles that I have Shorai batteries in, and haven't had any problems; the batteries have worked great.

Any battery is going to lose capacity over time. Temperature will also affect it, although my OLPC XO-1 LFP battery pack allows exposure up to 140F (60C). Check WikiP for LiFePO4 batteries. I suspect, that consistent with eneloop rechargeables, you will still retain considerable capacity after an extended period - perhaps even a full year or more; if fully charged & then stored under reasonable conditions. I'm pretty sure my earlier S250 doesn't use Low Self Discharge NiMH rechargeables [like eneloops] but it still shows some capacity (2 Green flashes, & runs through all light levels) some 3 months after I last fully charged the battery pack. I imagine these new LFP rechargeables are better still. Perhaps buy an inexpensive LED lantern, with a fresh battery, for cheap insurance - say around $10. UPDATE: With d.light products now using LiFePO4 (LFP from WikiP) batteries, a fully charged S300 should still retain some capacity after storage for a year - based on details for the S20 lamp. I don't know whether, as with my NiMH rechargeables, it is better to work the battery hard - ie "Rust out, or wear out". WikiP suggesting between 2,000 - 7,000 full recharge cycles for LFP. On a daily basis, that could amount to decades - in which time improvements in LED efficiency might make this S300 Lantern redundant. PS: The fully charged NiMH battery pack from my older [Feb 2011] S250 has just lasted some 5 months (with monthly checking), before finally being run down - RED battery capacity displayed. So some 5 Winter/Spring months [in Oz] for battery capacity to completely run down. Stored capacity would run down faster in a hotter environment. With an older Lantern (non-tamperproof screws?) it might seem desirable to, at least, fully top up the battery on a monthly basis. Then if you miss one monthly battery top-up, there might still be some half the battery capacity retained after being left for a couple of months!

I've had mine 2 years so I can't give you an answer on how long it will last but I didn't have it on a battery tender last winter, (Arkansas winter - mostly ice) and after sitting for a few months it was still at 92%. So while it lost a bit over time, it still cranked my RoadStar 1700 without a problem.

If you have a 12 volt battery NO PROBLEM. I have it on a BMW and I plug it in if I'm not going to use it for days. I also have it on a Motorcycle. YOU MUST DISCONNECT BATTERY TENDER BEFORE STARTING UP.

In order to find the actual reserve capacity, I would need to run this battery from fully charged down to 'below spec". I wont be doing that to my battery. However, this battery is "Medicare approved" which basically means it can be used in devices that DO that very thing, like wheelchairs for example. It also claims to have heaver plates and to be able to withstand 800 deep cycle discharges. The bottom line here is that the reserve MUST be good or it wouldn't make the Medicare approval list. Mine is in a Yamaha Roadstar 1700 and its been nothing but awesome, even in bitter cold weather. I replaced my OEM Yousa battery with this one and its clearly a better battery. That's my 2 cents worth, I hope it helps. In order to find the actual reserve capacity, I would need to run this battery from fully charged down to 'below spec". I wont be doing that to my battery.

Battery Tender site indicates multiple batteries can be connected in parallel. They need to be the same type and voltage but do not need to be the same capacity. If the connectors fit or can be made to fit, I think this would work as long as total capacity is within limits stated on Battery Tenders web site. For storing batteries over the winter, I would probably charge all batteries separately and then connect them in parallel using this or direct connects. I plan on taking a closer look at purchasing the item :-).

Hi Elizabeth. I'm using an Exide MC-31 MEGACYCLE AGM-200 (AGM) Marine Battery. Fully charged, this battery can keep the refer at 38 degrees for several days (depending on outside temp). I would not recommend running this off of a car battery/alternator.

3100 mAh is the capacity of the battery not the output. So no it shouldn't hurt it, just make it last longer.
