I have two Segways that we sadly haven't used this past year, and they weren't starting up, and one charging light on each was solid red.

This guide led me to buy a power supply, . . . and both Segways are up and running now!

I'm hoping this will work on my i2SE batteries.

I have the LiIon batteries trickle-charged to 60 V at 100mA, but the amperage is taking a while to reach 0; one pack is now hovering at 0.019A about an hour after reaching 60V. Wondering if it's okay to go ahead and re-connect them to the Segway and try to effect the charging there?

What is the result of installing on the base?

Thanks for pdf ,Instead of using nails I just clipped my power supply clips
to my multimeter jumpers instead and used the multimeter probes. It took about 5 minutes to charge to 60vdc..

I realize that this post suggested using 60v, but wouldn't it be ideal to use the 73.6v? Or is the idea to get it just high enough to let the onboard take over? Thanks

Yes. The goal is to give it enough of a float charge so the segway charger can detect the battery and start charging it. I've read posts that say 48v should be enough to do that although I haven't tested it out.

Should be good enough to try letting the segway charger do its thing.
Sorry for the super delayed post

Hi guys! we have the DGB International Battery Super Reviver. Does this process provide any additional benefit? In other words, is it worth testing batteries that the reviver has failed to revive?

Hi, I have try your battery reviving method on my dead X2 battery and its seem to be taking a long time to charge up. I am using a Wanptek 60V 5A dc power supply from Amazon. My batteries are showing 0 volts at the start. I set it at 60V and current at .1 the battery been charging for 3 days and only at 29volts current still at .018. In this case is the battery bad or do I need a better DC power supply charger?

I am posting this here in case It helps anyone else. This is for the original Gen 1 and Gen 2 Segway units. I do not own a Ninebot.
