當PLC的用戶程序要保留在RAM中時，就會用到電池，電池通常是3V或3.6V的不可充電的鋰電池，電池的使用壽命通常是五年左右，電池用久了，電壓就會下降，當其下降到不足以保證RAM中數據時，RAM中的程序就會丟失。如果用戶沒有備份程序，就會相當麻煩。[1]
一般PLC內部設有電池電壓檢測電路，當電壓下降到一定程度時，PLC就會報警，提醒更換電池。PLC的使用說明書都有提供更換電池的方法。一般來 說，PLC在斷電后，因為PLC上RAM電源端接有充電電容，即使把電池去掉，電容上充電電量也足夠RAM內的數據保持一段時間，所以如果取掉電池后在短 時間內（通常5分鐘）再將新電池換上去，數據是不會丟失的。
但用戶實際使用PLC的環境情況不盡相同，例如電容的容量下降，RAM電源回路有 灰塵、油泥等形成放電回路等，這會加快PLC斷電后電容的放電速度，從而使時間不好把握。如果在帶電的情況下更換電池就可保程序*。因為電源始終會 有電壓加在RAM芯片的電源腳。當然更換時亦要小心應對，注意電池的極性以及避免短路情況發生。
是把PLC通電15分鐘（給內部電容充電），斷電，在5分鐘內換好新的電池，再上電試一下。
西門子PLC有帶卡的，有不帶電池的；也有帶卡的，帶電池的。程序存在MMC卡中，如果沒有存儲卡，需要電池保存程序的，更換電池時候務必注意，帶電的情況下，將舊電池取出來，然后將新電池換上即可。
