21V MAX 4.0Ah Lithium, Lon Battery, Extended Runtime, LED Charge Indicator, Compatible with Tools, Outdoor Equipment

This fit my generic but not overly powerful blower that I use in my garage and shop. The original died and this battery restored the blower to original without having to spend much money. One less thing in the landfill and far less money spent. Score!

A battery, at a good price, fits and works well.

Battery worked fine on my blower and after four charges now only works for 10 seconds and then stops. Of course there is no warranty!

I got a blower from Amazon that the battery lasted 14 months. After 14 months the battery would run the blower 60-90 seconds. Could not find a replacement for less than $70.00. This popped up one day for under $20.00. Took a chance and it works better than the original.I have ordered a second one so I have a spare.

Works good, I wished the battery would last longer. Not a lot of choices out there for my hand blower to choose from. Charges very fast.

Worked well in drill

I bought a bargain-priced 21-volt pressure washer, but the manufacturer didn't offer the option of buying spare batteries. This battery fits the washer perfectly, uses the charger that came with the washer, and gives me additional operating time for big jobs. It's also rated at 4 Ampere hours, so it's a higher capacity than the 3 Ampere hour batteries supplied with the washer.

Bought hoping to fit my Seesi cordless caulk gun. It did, and also my Worx leaf blower also. Took full charge with easy to use charger.
