When PB Tech asked me to review this product, I jumped at the opportunity to do so.This put the light in my life. The spark in my circuit board, the tune back in my guitar tuner. I don't feel I was over-charged, at all. I was shocked, at how low the price was for this.

Price is more per unit. Reliability is thousands of times better. Spend 8 hours driving to and from a remote site to replace a ... MoreWith a fleet of desktop computers to support it's critical to have bios batteries to remember settings especially to enable auto start on the return of power.

I don't have any test other then field use. We now replace according to maintenance schedule. Panasonic delivers. This is a good product.
