Great value!

I got these to supplement my one battery I had for my weedeater. These are great and last for all the more I have to do around my house each time I have to use. They charge quickly and fit both my weedeater and my leaf blower. Just remember to periodically charge them as they will lose their battery power if sitting for a long time (over winter when not using). That is pretty much true of any battery tho. :)

When I started to trim the weeds in my yard, I used the new battery. I found on the medium stem weeds the battery life lasted exactly 10 minutes. I went straight through from start to finish or until the battery stopped the weed whacker. On thinner weeds, I believe the battery might last a bit longer. Good buy though.

Great power and fast charge. Helped my leaf blower clear the yard before the snows came

Shipped fast! Good recharge too.

These work in my snowblower but they run out of charge way quicker than my three year old original batteries.

My works blower and string trimmer still worked great. Used them for quite a few years. The batteries however started to get weak and needed charging more frequently. Broke down and bought these and its like i bought new works tools.

BEWARE THESE ARE 4Ahr BATTERIES NOT 7.5 Ahr! I load tested both of the batteries received, one came in at 3.3 Ahr and the other came in at 3.4 Ahr. Opened one up and the cells used inside are configures in the typical 10s2p using INR19/66 cells labeled at 3.7 volt at 7.4Whr (Watt hour not Amp hour). The cells are rated at 3.7 volt at 2 Ahr each so a total of 40 volt at 4Ahr per battery.
