## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Best quality pc board
  

*by G***E on Reviewed in the United States on August 12, 2024*

It is absolutely wonderful to discover that M18 batteries can be repaired by even the most average individual doing Electronics.  Everybody should learn to solder and desolder anyway.  It is much less expensive to assemble these types of batteries from kits.  PC boards do sometimes need to be replaced.  Saves tons of money over buying new batteries when only a small internal component is needed instead.
