Bigger is sometimes better
Works perfect get a lot more blow time out of the blower my wife loves this thing she's constantly blowing the deck off sidewalk pool cover now that it's winter she's even blowing light snow off everything well worth buying the bigger battery

works well, saves money only one downside
Have been ordering these for a while. They save money and hold up well. The only down side, the tools can't read the chip, so the power tool can drain the battery to zero if you don't pay attention. If you drain to zero, the lower voltage could harm the tool.

These batteries are great for the $
This is my 2nd time purchase of these batteries. I ordered the first pair almost 6 years ago. They still work fine, but my smaller batteries that came with tools are on their last few charges. I like to have 2 in play and 2 ready to go. They provide more oomph and last way longer. Like most Lithium batteries, if you work them hard, they shut down due to heat, swap the others in to let the first ones cool and then keep using til they need charging.

Longevity.!
This is my first pair of the 6.Ah battery replacement... so far I'm pretty happy. Fully charged, I spent 35 successful minutes with my blower -- then spent another 25 minutes with my faithful reciprocating saw --- could this be a trend.? .. could this be a positive future.? .. could this change my life.? Hopefully, this will last way past the Holidays. -

Good first but doesn’t last.
Worked great at first. Long runtime, more power for weedwhacker and blower but gradually got to be less and less. I purchased in Jan of this year and by late September it won’t charge and is basically useless at this point. I’m back to square one needing another battery.
