PSA: Issues with Some EV3 Battery Packs
Over the past few days I’ve seen stories regarding the LEGO Education EV3 Battery Pack circulating on the various forums and FB groups. Yesterday LEGO Education released a statement to customers and partners who are affected by this issue, confirming the problem. I’ve put a small excerpt of the statement below. You can download the full text here (zip file with two PDFs): [LINK].

Dear Customer , The LEGO Group prides itself in delivering high quality products and regrets to inform customers of an issue related to the LEGO? MINDSTORMS? Education EV3rechargeable battery . LEGO Education has identified a circuit error in the LEGO MINDSTORMS Education EV3 rechargeable battery . The error does not in any way relate to, or impact the EV3 programmable brick or the charger/transformer. The majority of the batteries that have been distributed do not have this error, but every battery in stock is now being retested to ensure it charges properly before shipping to customers, and new supplies are being sourced.


So in short, the issue is with the pack, not the brick. So for now, just use AA batteries until you can have the pack replaced (read the full letter how-to). Thank you Xander for posting this.

顺便，第一次发时，结果发时说没权限发URL，直接给我清空表单了，希望管理员帖子草稿能稍微做下，谢谢。

声明是发表在一分blog上的，附带LEGO发表的面向客户和家长的公告。

本人没有细读，可能写的消息出错，请见谅。大意是LEGO EV3教育版带的电池包可能没法充电，因为Set内的电池包预先充有电，客户只能在用完电充电后用EV3砖检测是否有毛病。
老实说看到这消息挺蛋疼的，下面附PDF原文。官方的说法是不影响智能砖的使用，发现有这个毛病的用户先使用标准AA电池，并联系客服。（国内情况就……）

Dear Customer,
The LEGO Group prides itself in delivering high quality products and regrets to inform
customers of an issue related to the LEGO? MINDSTORMS? Education EV3
rechargeable battery.
LEGO Education has identified a circuit error in the LEGO MINDSTORMS Education EV3
rechargeable battery.
The error does not in any way relate to, or impact the EV3 programmable brick or the
charger/transformer. The majority of the batteries that have been distributed do not have
this error, but every battery in stock is now being retested to ensure it charges properly
before shipping to customers, and new supplies are being sourced.
Customers who have received a rechargeable battery with this error will be provided a
replacement free of charge.
What to do if you have purchased a LEGO MINDSTORMS Education EV3:

1.When you receive your kit, the batteries will be at least partially charged and you may
use them straight away.
2.You will first discover the problem when you try to recharge the battery.
3.As there is no indicator on the charger to show whether or not the battery is fully
charged, you will not know if there is a fault until you put it back into your EV3 brick
and try to use it.
4.If at this point, it does not work, you should contact Customer Services at the LEGO
Group to arrange for a replacement battery.
5.Please be advised that you are able to use standard AA batteries in the meantime.
