I have a 2007 GSXR 750 that I've stored for the winter and now that winter is over, I wanted to take out out.

I went to start the bike today and it sorta shuttered but didn't seem to start. It appears the battery is fading cause the lights still come on but are extremely dim and the dash looks like its all reset and confused.

Curious, any advice on what I should do? Its a stock bike - should I replace the battery or get a charger for? If i recharge, what should I use??

Thanks

Awesome, sounds like a plan!

Does anyone happen to have an advise on what brands that they've use/trust? From what I've read so far, sounds like tender would be a safer over the trickle

I'm assuming I need 12v battery tender?

Thanks for the advice!

If you have an alarm like a scorpio or such that draws power all the time for giving a status out then you definatley need a trickle charger or disconnect the battery when stored. If the battery is anywhere near the manufacturers date of end of life you are best to just buy another battery. They don't go past the amount of months they are made for. It works like clock work. 12 months periods normally and its not much past the time if you are ever lucky. it's a science of how long the acid takes to eat through the plates where heat doesn't help matters.

Just buy the charger from Walmart. Its only $20 and works just fine. If you keep going dead then change out the battery. Plus the charger at walmart works well on my car.

PO had left the key on in my 07 750 and battery was dead.
Put it on a Battery Tender Plus for a day or two and now it's fine.
I'm keeping it plugged in whenever not riding. The battery on my SV lasted 5 years doing just that.

One thing to look for when buying a battery tender would be to make sure that brand comes with a set of pigtails that you can route from your battery to under the rear seat so it is easier to plug and unplug. They make battery tenders so small they just hang on the receptical like an old school phone charger, makes for very simple battery maint.

best way to do it is to check for bulging due to freezing and then trickle charge it and do a load capacity test, if it froze it will still have 12v but will only have about half the current load capacity.
the best way is to pull your battery for winter and store it fully charged somewhere it won't freeze and trickle charge it occasionally to keep it fresh.

unless you live in an area that doesn't see -30 celsius. in that case i'd charge it and check load capacity, replace if voltage drops too low during test.

push starting your bike because the battery is toast gets embarasing. lol

ill bet that your battery is dead. there is a reason why most motorcycle batteries come without the acid in it. if you let them sit for a while they can go dead. so even if you recharged it, the cells are weak and wont hold it for very long anyways. you need to get a new battery and by a battery tender. when youre not riding your bike, plug the battery into the tender. if you do that your battery can last years.

Plus 1. Wire the pig tails up and if you didn't do so get wire an inline switch so you don't have to do the paperclip trick. You can just flit the switch and its in dealer mode instantly.

Any tender you buy from a bike shop should be a smart charger and trickle it. Plus, if your feeling cheap. Why not just start the bike once every few weeks and let it run for 10 minutes.
