Battery Tender to charge Battery

[pickelhead]

How long would it take to charge a dead battery with a battery tender. Somehow a gremlin got into my garage and turned the key on for my spyder. (stupid gremlins!) pps::dontknow::gaah::banghead::trike::trike:

4/5 Hours minimum, Less if the battery is relatively new, Sometimes if you just want to get the Spyder started
and go for a long ride than maybe in an hour .:dontknow:

A 2 amp charge will take between 20 and 40 hours if the battery dead. If you run a Spyder with the battery to low you may get fault codes.

It is not an exact science, since tenders taper off as the battery voltage rises. A completely dead battery should take at least 35-45 hours or more with a Battery Tender Junior (0.75 amps), and 20-30 with a Battery Tender Plus (1.25 amps). Unfortunately, these chargers cannot begin to charge a fully depleted battery. They need to sense a certain amount of voltage before they can function. You won't know until you try. Best to use an alternate charger, or remove the battery and take it to the shop to be charged. You could jump start the Spyder and let it charge itself, but that leads to all kinds of problems, including overheating, limp mode before the battery charge is sufficient, stalling at idle, loss of power steering, etc. I don't recommend it.

Thanks Scotty!
I was wondering just how dead it must be, before it's non-reviveable? :shocked:

this may be the problem with my battery. I did not know this thanks guys teh more I troll on here the more I learn and the better my spyder owner I become.

Is your arm/shoulder all healed yet?

It is not a matter of whether or not it is reviveable, it is just whether or not a Battery Tender or its kin will charge it. Sometimes they have to be put onto a conventional charger (like a cheap trickle charger) to get some life into them before you can switch to the maintainers. The maintainers will not attempt a charge if the battery voltage is too low. How low varies from manufacturer to manufacturer.

So they kind of need a kick in the pants before you can nurse them back to health?? (If possible...)

Conventional 5-10amp charger ought to fully charge it in 4hrs or so. Or if yours has a 50amp start mode to get the Spyder started.

FWIW I sometimes let the charger start my other bikes in winter and then ride them to fully charge it in an hour. I think sometimes BRP designed the nanny to be too good, not allowing any shortcuts to let us ride.

With Product liability lawsuits costing what they do; can you really blame them?

Dead battery need a good CPR and EMT and DR to pronounce dead. To come back alive from dead is a miracle good luck:yes::yes::yes:

You should never use a conventional charger this large to charge a motorcycle battery. Not only will it damage the battery by driving the lead out of the cells or mats, but it can explode a small gel cell or AGM battery. nojoke

If the battery does survive this treatment, its life will be significantly reduced.

:yikes: Too high of a charging rate; right?

tender

it took about 48 hours for my 1 amp tender when the same gremlin got in my garage and low and behold turned my key on ...lolol ...it was so low that the bike would not turn over at all and the tender charged it to full capacity in that time span..but i would never put a full sized charger over about 2 maybe 4 amps on it. batteries are way to small for this..

 

[Bob Denman]

That's pretty close to Scotty's estimate of up to 45 hours... :thumbup:
