2020年5月在本站看到的jdread电子书可以180天打卡返现。由于长期看书，也有电子书包需求，就入坑了。最后也安全下车了。转眼两年多过去了。突然间才发现电子书的电池不能完全充满电了。冲到93%就不能再充了。而在不接电源的情况下，一会儿就显示还剩60%多。看书只能看不到一小时就提示低于10%电量了。两年时间，电池就废了。

但书还是需要看的。于是找售后，由于这款早已下架，只能自己寄到厂商维修。结果找人家不理。只有自己动手了。在淘宝上搜了对应电池，找了一家评价过得去的下单了。3000mAh电池到手28元。附送拆机工具等。先老板找了一个拆机视频，可以趁着国庆将电池换了。

电池到货了，电池很薄。生产日期为2021年10月。

先将机子关机，准备拆机。

拆机从正面开始，正面是用胶粘连上去的，背面是螺丝固定。由于没有拆机的刀片，只有用一字刀，一点一点将正面的边框翘起来。

胶粘连很牢固，用的两把一字刀慢慢撬。这里不能插入太多。不超5毫米，否则容易伤着屏幕。

花了半小时，才将正面拆下来。太费力了。这里要注意用力，但不要用蛮力。

正面边框上还残留很多胶。把能清理的清理掉，方便回装的时候贴胶。

剩下的上下各四颗螺丝拆卸掉即可。左右两侧是各四个卡扣扣住主体的。

背壳本身是有点软的，用手即可从一个角开始剥离出主体。

卡扣的位置可以用一字刀撬一撬。

后壳两分钟就拆分开了。没用胶粘连。

原装的电池是1600mAh，占了一半的位置。电池下方还压着一条黑色的数据线。

这里需要找到电源接头并取掉。

电池是粘连在主板上的，需要翘起来慢慢撤掉，不用怕把电池弄弯，直接撤掉就行，这里注意不要将下面的黑色线弄到即可。

拆下来的电池和新电池对比

剩下主板比较干净。

将新电池装在电池位，将电源线接上主板。这里要注意接头能看见金属触点的一面要向上。

将过长的电源线帮在主板上

接上电源后，自动开机了。电量还有60%。没做外框的遮挡，顶部的灯光也更明显。

确认没有问题就可以开始回装了。在将主板装入背壳的气候，可以倾斜一定角度再将主板按入卡扣的位置。这样可以更省力。

当卡扣位置都到位时，就可以装上螺丝了。

将配件中的胶涂在正面边框上，装回即可。

完工的边框上虽然能看见一些痕迹，但手感没啥影响。

将电子书正面朝下放在桌子上，用一本比较重的书压住，等待胶水凝固。

充电满以后，一夜掉电3%。

本来就是零元购的机子，久了电池废了。换新后可以继续用了。自己更换电池成本比较低，实在对自己没信心的买来电池给钱找修手机的换吧。免得把机子弄坏了。
