Dead Motorcycle Battery: Recharge or Replace?

My battery became 17V. Is it still okay to use it with my motorcycle?

Very educational, thanks for this video!

All great tests! I keep my bikes on a tender when not riding because some have electronics with a constant slight drain. If it sits to long those parasitic drains can ruin the battery. This should be considered for any vehicle.

Don’t buy cheap or unknown manufactured batteries, just buy a Yuasa, and know it’s going to last, especially if you use a battery conditioner like the OptiMate 3 Motorcycle Battery Charger & Tester.

This is brilliant! Great explanation. Thank you!

how about replacing acid or cleaning batt cells & adding acid back.

did several times and batts leasted more when 6-8 years

Something else your test showed is that the voltage didn't drop below 10 volts while starting the engine which indicates a good battery. Also you don't need a meter to tell the charging system is working - just watch the headlights brighten as you rev the motor! Great videos, very clear and fun to watch!

Thanks

Lol BS battery, that's funny. I actually have the same one. At least they labeled it accurately.😂 Thanks dude

Mine is at 9.3V , what should i do

Hi there @YouMotorcycle thanks so much for this video! I had a dead battery, I charged it fully, let it sit for 2 days, then used the multimeter and it read a solid 12.6v, after turning the key lighting up the dash etc. the multimeter read 10.4v and then hitting the starter, the engine turned over a couple times but didn't turn on at all. Does this mean my battery is actually totally shot? I'm just a little confused because it read 12.6v. Thanks in advance.

I bought a new yuasa battery 3 days ago for my motorcycle and it charged for 1 hour before plugging it in and I drove it on the highway for 2 hours and then I rested it for a day when I checked the next day its voltage is always in 12.4v and then dropping to 12.3 engine start at 14.2v does my battery needs more chrage or is it normal for new battery? hope you can help.

Version 1 e version 2 video are very helpful. Thank you

Hey man! I failed the second grade!

I like your videos

Thank you for the informative content. I am purchasing a multi-tester tomorrow.

I’ve got my bike in 2018 brand new done 60k miles on it and battery is still the one it came with

But I’m being told I need to buy a new battery for £100 for my 2022 mt09 Because I made the mistake of leaving the battery in the bike for a whopping 8 months without any use. Now, when I turn the key, only the ABS light flickers for a few seconds, and nothing else happens.

My yuasa read 10.70 -.- whyyy it’s only been 6 months total

On my 3rd battery. I didn't know if it was the battery or my charging system. I got the first 2 where u add the acid but they both failed no sure if it was because the store added the acid and didn't wait the 30 minutes before putting the caps in. Every time it went dead the caps were coming out of the holes. I got a new sealed battery today and so far so good but I will be going to get a multimeter tomorrow to check my charging system. Anybody have any other suggestions?

i will get my multi meter out

Thanks. Awesome video

What if you are charging it off the bike and its not fully charged but reading mid 13s or higher ?

Thanks for the video it’s stuff like this that if you jus5 take the time to watch the video you’ll actually learn something that will stick with you forever.

very useful video - saving it

Thanks bro! Yup my Gsxr charging system sucked wasn’t sure if it was the case but your video helped

Thank you

Awesome.

The battery you test is drained?

thanks for this video. it really helped me sort some crap out with these batteries. wanting to be self-sufficient with this kind of stuff but not knowing how is a real pain in my bean-bag. Sincere-iously, it's the emotional equivalent of having a chaffed scranus. so thanks again for the salve.

Thanks for the very informative video. My pigtail is connected to what's called an 'output terminal' on my fusebox for attaching electrical accessories. Could I still use that pigtail connection to check with a multimeter as you instructed in the video? It's a pain to access the actual battery connections.

Excellent Simple Video!!! 5 Stars- Thank You!

Great

Thank you for that information. I'm going to go check mine now b/c I'm not sure if my issue is the battery, my tender, or the bikes charging system. Ride Often and Ride Safe ✌️

Very informative! Literally never seen this covered and been watching a plethora of YT videos on bikes since the platform started.

Hey Adrian, great videos and a great learning tool for people getting into motorbiking. I just wanted to check something. I don't have the battery tender connector that you have in the video (CTEK one is on order with a full tender system) so would I be ok to check the motorbike charing system to put my multimeter on the terminals on the battery when checking this? Or should this only be done once I have the connector? Thanks in advance :)

Thank you!

Good vid. Waiting a couple of hours after charging to test the battery voltage was a new idea to me.

I think you mentioned something else briefly but another charging system problem to look out for is too much voltage when the motor is running. My Suzuki started having brighter than normal dash lights a while back. I thought maybe I was imagining it but I checked with a multimeter hooked up to the battery terminals while it was running and it was over 18 volts! I stopped riding it around before I fried anything and got a new regulator/rectifier. With the new reg/rec installed it went right back to about 14.3 volts.

Absolutely awesome video!!! PLEASE KEEP DOING THESE THEYRE AWESOME!!!!

Nice🐕

Hi Adrian - Another great video. I have always kept my bikes on a trickle charger and haven't had any battery problems, yet. I'm going to get a Load Tester and start checking a few times a year. And good to know you can use the pigtail instead of taking things apart to get on the battery terminals.Definitely worth it not to get stranded. Thanks!

This video is exactly what I was looking for. I have the same load tester which I got at Harbor Freight a while ago. I wasn't sure if the 100 amp load of the tester would be too much for the battery. I feel more confident now to use it on my 28AH motorcycle battery. Thanks for the great video.

Thank you for this...glad I chose this video to start with...my battery is going on 4 years old and is on a tender for the winter...it's the original battery so I'm not sure what the brand is. But I don't want to be stranded so I will test my battery for sure before spring riding season. I do have the battery tender pigtail so yay me!! And by the way, Eric from Kraken's Garage sent me your way. He's got some great content. 🏍💜💯

One additional tip might be to ensure the connections are well cleaned and tight.

Adrian, a very useful solid video on helping good folks with the care and maintenance of their bikes. Eric

Good video Adrian. I keep my battery from my Spyder on a tender indoors for the winter. But, I have never thought of checking the charging system after I reinstall it in the spring and periodically through the season.... good tip, Thanks.
