battery tender?
4 moto batteries wired in parallel,


sound legit to use one tender?

nope you'll want them in parallel, though not sure how your tender will deal with four batteries with varying needs

Not necessarily.

What will happen is the batteries will equalize, and if you've one weak/bad cell in one battery, it could well ruin the other three.

And I don't know if 900ma/4=225mA will be enough to float charge the batteries.

And just ignore anything FFF says about battery tenders

One needs chargers for the specific batteries. IE Lithium, Gel Cell, Wet Acid Cell, AGM. There are chargers designed to charge mulitple batteries at once. I use two different versions of the "BatteryMINDer." For the car which will soon sit until spring, and the PU, I use Model 12248, which has a temperature sensor attached to the terminal to shut down the charger in case of overcharging. It also has selections for Acid-Flooded, AGM and Gel Cell. With charging selections of 2-4-8 amp; With auto Desulphator-Conditioner. For the tractor, bike and boat I use the less expensive 2amp BatteryMINDer Desulphator. (about $39.00) I got 11 years service from the tractor battery and the truck's are past 7 and still going...AJ

Yeah it's the varying needs part that I wasn't sure about
So it's separate Battery Tenders for all...

like you, i tihnk this may be my only option.


2 of which i think i can get away with as both are new gel cells jobs, the other 2 not so much.

It would be a Bad Idea to mix different types (wet, gel, AGM, etc.) of batteries in any configuration, as the chemistry, and thus the voltages, are a wee bit different in each.

I've had great luck with the Yuasa SmartShot trickle charger maintainers.

Watch the cheapo HF maintainers: they're not rated for AGM or gelcell batteries. They seem OK for a normal wet cell.

I dont see a need for a tender if you ride the bike often, but...

...if I were in your shoes I would go with a NOCO Genius over a Deltran Battery Tender. They have a whole lot more technology packed in their systems. A NOCO Genius G4 will support four different batteries at one time.

As was stated earlier, running unequal batteries in parallel may cause the life to be shortened.

i wouldnt say 230.00 is cheap when considering will keep moto batteris, and vehicle batteries charged up.

but it seems to be the answer

Traditional/correct battery storage will save you a bunch and be better for the batteries. Fully charge, disconnect, cover terminals, clean the casing with a damp cloth, dry, place on wooden floor or board and store in a cool (not cold) dry place. Check condition of batteries at least on a monthly basis and recharge every 3-6 months or as and when charge drops below 80%.

There are occasions when tenders are hugely convenient but batteries do best if they are either in use or disconnected and stored correctly.

Not necessary, old wives tale. Proven this wrong time and time again. Used to be true when battery cases were made from hard rubber, as they were somewhat porous and had a high-carbon content. An electrical current could be conducted through it when placed on a concrete floor, causing a weak short circuit.

But today's batteries cases are ABS plastic and can sit on concrete indefinitely.

Batteries discharge slowly all the time. . . so regardless of where you leave one, if it sits long enough without being recharged, it will go dead.

I can't remember the name of the product. It is designed to use with a single 'smart charger' I'll try and find it. It looks like a spyder.
Your smart charger plugs into the unit. The unit has 4-5 leads coming off it going to 4-5 batteries. The unit has its own 'smartness'. it monitors each battery and charges as needed. Now you can have one smart charger doing the work of up to 5.
Retail for the unit is $90.00. I'll keep looking for the info.

It is best practice (not necessary) to have a cheap disposable material (like wood) that forms a physical barrier between the battery and the structure it is temporarily stored on. Should the battery leak or suffer charging damage acid will not damage your shelves or garage flooring. The nice thing about wood, for concrete floors, is it helps prevent the floor cooling the battery below ambient air temperature which you intended the battery to be stored at.

Temperature of the stored battery will have a much greater significance on self-discharge rates than any possible/theoretical capacitive discharge effects of storing on concrete. Worrying about lime leaching into the battery is very old news indeed and not relevant in todays POLYPROPYLENE cased batteries.

Since my wife sees fit to mention how cold the floor is and why I don't use something to stop dirt getting on the garage floor I'm going to have to agree with you that the origins are most likely from a wife.

Best thing you can do for your batteries is keep them charged, no matter what method you use, and no matter what they are on. Keep them charged by running the bike often or monitor them on a charging system.

It is when they are discharged that they become highly susceptible to irreparable damage.

If you want to be a real cheap ass, just use one tender and swap it to a new battery every morning. Added bonus is that it gives you an excuse to go out to the garage every day.

going out to the garage every morning wont help anything, needs to be every night.
