Battery Dead On Arrival : 2 solutions

Solution 1 (thanks to MR H)

The Mini PRO is under warranty

 

You put it in charge 24 hours

Why?

It is possible that the charger has gone into safety mode, so during its charging, it has micro-cuts.

So the charge will be very slow.

After one night, the battery will have received enough charge,

and normally the Mini and the charger could resume their normal cycle

 

solution 2 (thanks to smallexis)

The Mini PRO is not under warranty

 

If you have electrical knowledge

 

Check battery voltage

 

 

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

 


The Mini Pro are now too old to sell.

 

They came out in November 2015, then there were others made in June 2016, if the batteries are over a year old, without being recharged, they do not turn on anymore.

Mini Pro buyers in France and the United States testify that they can not turn on the Mini PRO.

 

Do not buy Mini PROs that have been stored for too long

Last week I saw a Mini Pro in a shop, it has not moved for a year, the tires are deflated, I imagine that the battery has never been recharged

 

But a Mini Pro buyer import from China has not had this problem, more recent manufactured in 2017 (see pictures below).

Since they were activated in China before being sent, they are therefore in working condition

 

Ask the seller the production date, tell him it's because of the batteries.

There is a sticker on the cardboard, the year appears.

If it's 2016: do not buy it

 


HOW TO VERIFY DATE OF MANUFACTURE (building date?)

Thanks to More4Mini

Exemple:

 

N3MTB1636T0738

 

16 = year

 

36 = week

 

T = rev code

 

0738 = serial number

 

If it's a Mini Pro or Mini build in 2016, please , forget it !
