received immediately and happy to have it. great product. great price and great TAT
got it in less than 24 hr... since I was homesick on the day, took the challenge to change the battery myself instead of bringing it to the store, the manual with pictures totally WELL explained... crystal clear. EASY to follow. I resurrected this 12-inch laptop which is my fav for traveling but I had it at home for 4-5 years since was useless without cable. I thought it was old but it not, it was ALL ABOUT THE battery. And now is like new. It took me 30 mins or 1 hr max... put it back ... then didn't work but it was my bad (I had disconnected one slot that is not indicated in the guide and missed pressing and clicking the little slot back into its place. So I opened it again, did that, and VOILA !!!! amazing product. fast to get it. fast to install DIY and price... so fair !!! lets see how long it lasts the battery... but if that goes for at least 1-2 years (battery non-electricity) its great.

A new lease of life for a 7 year old macbook
The alcohol to loosen the glue for the old battery is not provided, but that might be because the supplier is not allowed to provide. We were lucky that we had some alcohol, but it would be useful to know this so it could be ordered separately. Cleaning off the old glue took me 15 minutes for each of the 6 sticky sections. Everything else was straightforward. The instructions provided are easy to follow. The battery has worked well for the first two days since replacement. Sometimes it needs to be plugged in to start up, but that might be a problem with the hardware itself given it is 7 years old. Screwdrivers provided are magnetised which is helpful given the small screws.

Lebensverlängerung für das 12" Macbook - Kapazität weicht ab
Im Lieferumfang ist fast alles drin, was man benötigt, um den Akku selbst zu wechseln. Die bebilderte Anleitung zeigt jeden einzelnen Schritt und was im Speziellen zu beachten ist (z.B. den DISCONNECT-Button auf dem Mainboard zum sicheren Abklemmen des Akku unbedingt verwenden). Die Schrift der Anleitung ist allerdings recht klein und etwas schwierig zu erkennen. Sowieso empfiehlt sich, eine alternative Anleitung zu verwenden, z.B. von iFixit. Es müssen aber nicht alle dort beschriebenen Schritte durchgeführt werden: die komplette Demontage des Mainboards ist nicht erforderlich. Allgemein ist wohl dass Entfernen der Befestigungskleber die zeitaufwendigste Angelegenheit. Die auf der Rückseite dieses Akkus verwendeten Klebestreifen halten den Akku "gerade so" in seiner Position. Das liegt vermutlich auch daran, das dieser Ersatzakku nicht wie das Original "terraced" ist. Die beworbene Kapazität von 5300mAh wird nicht erreicht, stattdessen sind es 4800mAh ("Design Capacity") und 4946mAh tatsächliche Kapazität. Das Herstellungsdatum des Akkus wird mit 2015-03-30 ausgelesen - der Akku wäre demnach bereits 8 Jahre alt. Nach dem erfolgreichen Einbau verhält sich das Macbook 12" unauffällig und funktioniert bisher einwandfrei - ca. 8-9h Nutzungsdauer sind jetzt wieder möglich - Top! Trotz der kleinen Schwächen hat sich der Austausch für uns sehr gelohnt.

何度も予習してから取り組みました。
このバッテリー対応のMacbookは、その交換作業の難易度は高いほうに分類されるでしょう。 しっかりと予習してから臨みましょう。 私のMacbookはY字ドライバーが必要でした。やはりドライバーがないと、ペンチやそのほかの代用工具では外すことはできません。 1.付属のオープナーだけで、本体に傷をつけることなく、開くことができます。 2.Macは見た目は綺麗かもしれません。でも5年も経っていると内部の劣化は想像以上です。特にウレタン(スポンジが加水分解している)、コネクタ周りのテープが劣化しています。外すことはできても、綺麗にに同じように戻すことはできなくなります。私の場合、音声ケーブルの接触が不良で3回ほどコネクタ接続をし直しました。諦めずにトライすればきっと大丈夫。 3.予習のYouTubeによっては、電池裏面の両面テープの残骸を綺麗にせずに交換してしまっています。がんばって綺麗にしましょう。その方が断然気持ちがいいです。ある程度取ってから、アルコールで拭くととてもきれいになります。高価なエタノールでなくても、燃料用アルコールで大丈夫でした。ドライヤーを当てるときは背面からのほうがいいかもしれません。 Macbookが生き返ってすごく嬉しいです。バッテリーの持ちは当初悪いように見えるかもしれませんが、検索してみましょう。SMCリセットはしたほうがよさそうです。
