Review on Enhanced Performance: Fluke BP190 Rechargeable Capacity ScopeMeter - Revolutionizing Test and Measurement Efficiency by Johnny Bloomer

Now my oscilloscope is like new. Expensive for what it is considering the original battery only lasted a year with moderate use. Not a great price, but the selection is really small (they don't use standard sized cells, making it difficult to replace them yourself), bite the bullet if you want your Fluke scope to work.
