Christmas buy Segway Minipro 4 days eariler.

Open Xmas day and dead.

No lights.

Only the charger light on the power brick is green.

Call / e-mail / option 2 gets me an e-mail okay to break battery seals and take off Minipro.

Directions state charger battery directly OFF the segway.

Check to see if light on battery itself, is on and what color: nothing.

If I unplug the charger cord from the battery and then 15-30 seconds later plug it back into the battery I get four red flashes then no light ON the battery itself.

 

What are the 4 red blinks code for?

 

TIA !

@Suf. I'd assume the battery is dead (and was already dead at arrival) and by this is a warranty issue.

There isn't a piece of plastic between the battery terminals, is there? To make shipping safer.

Segway is sending something to us from Los Angeles.

Either a MiniPro or a battery.

I e-mailed support, and called them (option # 2) in NH.

When I separate the battery, and directly plug in the charger, nothing happens for 2+ hours.

In their service request form instructions they ask us to separate the battery and see the LED light ON the battery.

Ours did nothing.

IF I unplugged the charger from the battery wait a few seconds and plug the charger back into the battery ALONE, I get 4 red flashes.

I told Segway this and they are replacing something from the distributor.

I wait for a package.

:-)

Dear S,

 

Thank you for the information and sorry that the miniPRO battery is dead.

 

The unit will be replaced, and our distributor will be in touch with you today to make the arrangements.

 

Kind Regards, Gene

Process outlined in your tech support attachment does not work on this MiniPro.

When the battery removed from the MiniPro, is "charging" or was disconnected from the MiniPro, there is no light on as in figure # 4 of the service process.

 

WHEN the charger is unplugged from the battery alone, then reconnected; the battery "light" blinks four red flashes then nothing.

Charging 180 minutes provides no difference.

 

This battery pack is dead.

Charger cord brick shows green light.

Only light I've seen until separating the battery procedure described above.

Service request attached w/ sales receipt from Best Buy.

Please advise.

Sorry to hear you were having difficulty with your miniPRO not starting.

 

There is a chance the battery has gone into a hibernate state and the attached could resolve the issue.

 

If the attached does resolve the issue please complete the attached service request form and send it back so that I may update your service history for any remaining warranty on the unit to not be voided by cutting the tamper proof labels.(IMPORTANT!)

 

If it does not correct the issue please complete the attached service request form so that we may start a warranty claim.

 

Kind Regards, Shane

I purchased  my mini pro from a private seller and once I took it home and tried to charge...nothing no lights no charge of anytype...i followed instructions I saw here on this forum took battery off presumably because I had no warranty due to buying from private seller...once I plugged in charger...4 red flashes then nothing ....is there anything else I can do or am I just out of luck?

WHy didn't you contact the seller first ? what he said ?

I think it is time to ask for help to the international battery specialist !

@Jbrannen95, I have had a phone call with @jojo33 and he told me your problem

if the battery is detached from the mini, which voltage do you have here?

image.thumb.png.44dbdce01d7a0c1e21193779984fcc88.png

if the volatge is between 42 and 45V, it's possible to try this :

I have saved my battery with this method but I can't give you the guarantee it will be the same for your battery.

good luck

@smallexis, My son's NineBot minipro has been sitting idle all winter inside.  He went to charge it today and it won't respond, the charger brick stays green, the display on the minipro doesn't light up nor will it turn on.  I pulled the battery pack and the LED on the battery pack is just blinking red.  I got a voltage reading of 24.6 to 25.0 volts at the battery terminals.  I am interested in your above mentioned method of possibly directly charging the battery with the home made connector.  However, are my seemingly low readings of 24.x volts too low to attempt this safely since it is far off from your suggested 42 to 45 volts?  Kind of disappointed that this battery may be trashed since it's not that old and it's $300 USD before shipping for a new one.  Thanks for any information.

Presumaby the battery is just dead and has to be replaced. Liion cells are very sensible to low voltage conditions. Theoretically there could be ways to revive the pack on cell by cell basis if the single cells have protection cuircits inside, but most likely they are just dead (internal short cuircits which makes them quite dangerous if one tries to recharge them again!)

Never let them on low charge for longer periods... Second worst thing for liion is high temperatures at full charge for longer periods.

Yeah I figured. Thanks.  This was my son's device, not mine so I was out of the loop.  I told him before to manage that battery like I have to with the LiPos I use on the drones.

I let mine sit too long and found it to be completely dead. I contacted Segway and they provided me with the same instruction as listed on here. (waking the battery up from hibernation)

It did not work. The red light flashed 4 times and stopped. The battery is only warrantied for 180 days and I was out of that period. I ended up ordering a refurbished battery from Segway ($130 vs $299 new). It is now up and running again.

I checked with Battery Specialist to see if they can restart the dead battery and they advised that it would be dangerous. The only suggestion I have so far is to take it to a recycling center.

This damn thing is costing me way more than it should. Lesson learned.

This has worked perfectly for me. I left the Segway unused for 5 months and it did not turn on.

I have opened the battery pack and wired it directly to the original charger for 20 min , after that i have seen the little green led flashing on the battery and i have mounted it back to the mini bot and recharged it normally.
