当PLC的用户程序要保留在RAM中时，就会用到电池，电池通常是3V或3.6V的不可充电的锂电池，电池的使用寿命通常是五年左右，电池用久了，电压就会下降，当其下降到不足以保证RAM中数据时，RAM中的程序就会丢失。如果用户没有备份程序，就会相当麻烦。[1]
一般PLC内部设有电池电压检测电路，当电压下降到一定程度时，PLC就会报警，提醒更换电池。PLC的使用说明书都有提供更换电池的方法。一般来 说，PLC在断电后，因为PLC上RAM电源端接有充电电容，即使把电池去掉，电容上充电电量也足够RAM内的数据保持一段时间，所以如果取掉电池后在短 时间内（通常5分钟）再将新电池换上去，数据是不会丢失的。
但用户实际使用PLC的环境情况不尽相同，例如电容的容量下降，RAM电源回路有 灰尘、油泥等形成放电回路等，这会加快PLC断电后电容的放电速度，从而使时间不好把握。如果在带电的情况下更换电池就可保程序万无一失。因为电源始终会 有电压加在RAM芯片的电源脚。当然更换时亦要小心应对，注意电池的极性以及避免短路情况发生。
设备拆装顺序及方法
（1） 停机检修，必须两个人以上监护操作；
（2） 把CPU前面板上的方式选择开关从“运行”转到“停”位置；
（3） 关闭PLC供电的总电源，然后关闭其它给模坂供电的电源；
（4） 把与电源架相连的电源线记清线号及连接位置后拆下，然后拆下电源机架与机柜相连的螺丝，电源机架就可拆下；
（5） CPU主板及I/0板可在旋转模板下方的螺丝后拆下；
（6） 安装时以相反顺序进行；
检修前准备
（1） 检修前准备好工具；
（2） 为保障元件的功能不出故障及模板不损坏，必须用保护装置及认真作防静电准备工作；
（3） 检修前与调度和操作工联系好，需挂检修牌处挂好检修牌；
检修工艺及技术要求
（1） 测量电压时，要用数字电压表或精度为1%的万能表测量
（2）电源机架，CPU主板都只能在主电源切断时取下；
（3） 在RAM模块从CPU取下或插入CPU之前，要断开PC的电源，这样才能保证数据不混乱；
（4） 在取下RAM模块之前，检查一下模块电池是否正常工作，如果电池故障灯亮时取下模块RAM内容将丢失；
（5） 输入/输出板取下前也应先关掉总电源，但如果生产需要时I/0板也可在可编程控制器运行时取下，但CPU板上的QVZ（超时）灯亮；
（6） 拨插模板时，要格外小心，轻拿轻放，并运离产生静电的物品；
（7） 更换元件不得带电操作；
（8） 检修后模板安装一定要安插到位
