Rated 5 out of 5 by from A great addition to my chainsaw! As I get older, it becomes harder and harder to start a gasoline-powered chain saw. So I bought a Greenworks Model 20312 40V chainsaw kit in July of this year and I love it! The saw is light, starts at the push of a button, is vey quiet, and is very efficient. However, when the battery is exhausted after about an hour of cutting, it takes 1.5 hours to recharge it. So I bought a back-up battery 2 weeks ago. Great move - it saved my neck. A rock maple (14 inch diameter at the base) had fallen across the narrow trail in my back woods. The saw cut this very hard tree well into smaller pieces until the battery died. My back-up battery allowed me to cut my way free. The alternative would have been to back up my Polaris Ranger 500 feet - a pain in the neck!

Rated 5 out of 5 by from Great Performer I've got (3) of these batteries that came with tool kits and have been using them for the past 3 months. Very impressed with how long they last, even in the most taxing of my tools I currently have ... the 24322 blower/vac on high speed ... it lasts long enough to get all my blowing done (30 minutes or so) on one battery and usually with some life left. Since I have 3, it would not really matter if I had to change out midway through, but it is real nice that I don't have to. In my 21" MO40L01 Push Mower, I was able to do 2/3 of my 15,000 sq-ft. yard (about 40 min) on one charge ... swapped out to a 2nd battery and had a half charge left when finished with the other 5000 ft. area.

Rated 5 out of 5 by from Great battery and great mower!! I bought my mower June 2013 at Lowes. It is extremely convenient and has never required any kind of maintenance. As I was living in upstate NY, it sat in a cold garage for about 7 months of each year. This spring I moved to Texas and the mower and batteries were shipped and packed into storage while I shopped for a house. When we pulled the mower out and charged the batteries 4 months later, it started right up. At first, I was concerned as my batteries did not seem to power the lawn mower for as long as they did previously. That is why I ordered an additional battery. However, once I had depleted and charged the original batteries a few times, they seemed to work better.

Rated 2 out of 5 by from Battery doesn't last Bought this battery less than 2 years ago-of course I threw away the receipt! At it's newest, it never held a charge for more than an hour, if that. Now, lucky if I can get 15 minutes at full charge! Just had to buy another since I can't afford to buy another whole lawnmower right now! Next time, I'm getting a gas mower!

Rated 5 out of 5 by from The heart of all my tools keeps ticking along! Over the years I've bought several greenworks tools. So far the lawnmower, string trimmer and blower have all been just wonderful. Each came with a battery, so I have a ready backup no matter with tool I use. Now I'm waiting for other older tools to die so I can upgrade to greenworks!

Rated 2 out of 5 by from Wish it lasted longer. I've had mine for about a month. Bought it new and consistently getting 12-16 mins of cut time on the 21 inch mower. It takes me about 25 mins to cut my yard so unfortunately I'm having to cut, charge for an hour and finish the cut. Wished that I could get the advertised cut time.

what is the replacement for 29727 Battery? also what charger will work with replacement?

Asked by: AQRA
I too am interested to know what the replacement battery is for the 29727 Battery(UK battery number). The answer provided by Greenworks has the model number incorrect. I think the 29472 is interchangeable.
