Description
BR-2/3AE2SP Battery (3V 1200mAh) — Industrial PLC/CNC Memory Backup
The BR-2/3AE2SP is a primary (non-rechargeable) 3V lithium battery in a 2/3A cylindrical size, commonly used as a memory backup / retention battery for industrial control electronics. Many systems use this type of cell to maintain critical settings, memory, or real-time data when the main power is removed.
Common Uses / Applications
- PLC memory backup (programmable logic controllers)
- CNC controls and industrial automation equipment
- Industrial control boards requiring 3V retention power
- Measuring / monitoring instruments where stable backup power is required
