Time will tell

Jul 21, 2019

Arrived after a bit of a delay due to shipping restrictions.
One cell was down to 2.0V which is the minimum for recovery. It did charge up after a balance charge. Time will tell if the low cell is a problem long term. It does power a 100W amplifier better than a car battery.

great batteries

Aug 21, 2018

I got these to replace some cheap SLABs which I use with my Yaesu FT857D radio when I'm portable. I haven't been disappointed. I probably could have bought one instead of two as one battery seems to be lasting a lot longer than the two SLABs.
Great batteries. Good support a well. They didn't have these in stock so I had to wait, well worth the wait and the updates I got and then telling me the leads I needed to buy to charge them.
