分享喜悦，macbook 免费换了电池和屏幕和键盘 （附刷电池健康脚本）

什么意思哦，免费的吗为什么给你免费换呀，分享来看看

忘记说了我有 apple care，当然如果没过保应该也是可以免费换新的

刚想问你这apple care还在保吗，你这是买了多久的apple care？当时花了多少

4 年，第1-3年 2000 多一点，第四年订阅是 900

脚本分享下唄，我的电池一直处于80%都快一年啦还没掉。ac今年6月份到期。实在不行按年续ac

同款，上个月刚续费ac，849，电池还坚挺80+。如果我一直续费，活到产品配件停产，是不是就能给我换一个全新的了 ^-^

我找找，ai 写的，你也可以让 ai 给你写，续费无所谓的，可以按天退的

那倒是没必要，一直续费估计还得续个四年，又要 三四千 块钱了，那为什么不买个新的，你还电池基本上就能换下半部分全套了

免责声明：这个完全看运气的，不一定能掉的，我的循环都 1050 了也该跌了

脚本是cc写的，请稍微审阅下，不保证 macos26 是否可用

# ============================================================================

# Battery Cycler Installer — MacBook 电池循环刷坏工具

# ============================================================================

# 用途: 通过自动循环深放 + 满充 + CPU 满载，加速 MacBook 电池健康度下降

# 目的: 在 AC+ 保修期内让 Apple 系统健康度跌破 80%，免费换电池

# for 佬友们

# 不保证最终有效，只保证快速电池重放循环，如有硬件损害请自负责任

# ============================================================================

#

# ⚠️ 使用风险

# - 长期满载 stress-ng 会让机器噪音大、发热

# - 极深放电可能触发 hibernate（机器假死）

# - 对电池是"加速损耗"，目的就是把它弄低健康度

# - 效果不保证（苹果黑箱算法疑似长期锁死 80% ）

# - 不建议对公司配发的电脑使用

我只在 macos 15 上测试过，macos26 不一定可用

有疑问请询问 ai，也是 ai 写的，也可以让 ai 来审查

拿到文件后在他自己的 Mac 上执行：

bash ~/Downloads/battery-cycler-installer.sh （改成实际路径）

可能需要 chmod +x 授权下

安装完成后朋友要主动跑一条命令才开始：

launchctl load ~/Library/LaunchAgents/com.$USER.battery-cycler.plist

等脚本了，没想到还有这么厉害的脚本，正好今年低也要到期了。

发了啊，看上面，只不过这个玩意不保证能降低的，本质是用 1 个半小时放电，再用一个半小时充电，过充过放，开机自启，自动循环

我跟佬差不多，不过ac应该过期了，我一直都是用那个AIDENT的软件，充电到80%就用充电供电，不用电池供电，现在依旧坚挺着

macos26.4 有系统级的电池管理了

已加入书签等时间到了就用它试试，手工费收了多少咯？

没升级到最新系统，我是非必要不升级，不然bug确实让人难受

全部 0 元，这个属于是他们质量问题啊（或者说属于质保范畴），不是我人为的

换屏幕他就让我升级了，不然数据写不进去，难绷

这样的么，涨知识了，看看还能再战多久，M5出来的时候有点心动想换的，哈哈

编辑到主楼了，麻烦你看下（总感觉自己发了好多次了）
