Best Uses

  • Use With Pb360 D Radio

I purchased this battery for my Power Box 360 Deluxe Radio. I was only getting 2.5-3 hours of use out of the Bat609 slim packs. That is just not acceptable for tailgating! The Bat620 is great! I have yet to drain it in a one time use but came close after 8 hours of near full volume use. It may be bulky attached to a drill, but no worse than the old NiCad batteries were. The fuel gauge is a nice feature. Overall great product.
