Does the 4.0AH battery use the same charger as the 2.0AH battery?

I have the blower which I like very much but can only get about 30 minutes from a charge if I do not use turbo and turn it to the middle between High and Low. If I turn it up all the way I get about 20 minutes. I am thinking of buying the 4.0AH battery based on some other questions and answers here but don't want to have to buy another charger.
Asked by: Bob1956
It can use the standard charger. Of course ,it will take twice as long to bring the larger battery to full charge.

Will the BA2240 battery work on the standard charger?

I bought the blower and love the power and noise level is acceptable. The standard battery only last about 40 minutes after a full charge. I'm thinking of buying a spare battery, the high capacity BA2240. Will this battery fit in my standard charger?

56-Volt 4.0 Ah Battery is rated 4.5 out of 5 by 159.
Rated 5 out of 5 by from Blown away!!!!! I bought my mower and weed eater 2 years ago. I was so please to find out that I was able to register my product even 2 years after purchase. This was important because my mowers 4.0 battery went bad. Customer service was outstanding and I am so glad I bought this outstanding product from an outstanding company.

Rated 4 out of 5 by from Much longer run time than the original battery that came... Much longer run time than the original battery that came with the chain saw. Cut up 2 small trees and did some trimming and still had plenty of power left over.

Rated 4 out of 5 by from Good battery I can use one 2.0 and weed it 200feet of Ditch and part of the yard. With the other 2.0 it only lasts for 1/2 the ditch. The 4.0 lasts to do the ditch, and around the house exterior, around 10X20 shed, along 160 feet of chainlink fence and still has power left. I always recharge it when I'm thru so I don't know how much longer it woul run if I didn't charge it

Rated 3 out of 5 by from EGO 56 volt battery No probs w battery order from Home Depot (even received earlier than originally projected). Too bad I will have to do this every 3 years since that is the extended life of the battery (matches their warranty); hopefully the price will not go up each yr.

Rated 4 out of 5 by from OLD FOLKS DREAM COME TRUE! WOW! No pulling cords; no working around electrical cords, the EGO POWER battery is the only way to go when you can't start a mower. I have owned an electric mower in the past and carrying around an electric cord was a hassle. Then I tried a push mower (yep, the old rotary blade)! Well, I am still able to do my own yard work; but, all of the pushing and rolling over and over the same area of grass will wear you out FAST! Push button is great! My only other option would be a goat and that wouldn't work in a residential aea.

Rated 5 out of 5 by from I've hve the mower, string trimmer, hedge trimmer and hand blower. I called in today to explain ... I've hve the mower, string trimmer, hedge trimmer and hand blower. I called in today to explain that I was having issues with the battery. It wasn't taking a charge and even the times that it seemed to, it wouldn't hold it for nearly as long as when it was new. The rep was excellent, understood my issue, and quickly helped initiate the warranty replacement on the battery. I've had this equipment for 2 years now and have definitely enjoyed not using gas powered tools!

Rated 5 out of 5 by from Great power delivery So excited about our new mower. We have 17,000 sq ft of grass, so needless to say I don't mow the entire lawn w/ the Ego, but it's so much lighter than my old Honda & has all the power. The bag catcher design also kills the old Honda. All I have to do is lift the rear door to ck & see how full. Love the variable speed & deck height adjuster. Couldn't be happier, great design & really gets the job done.

Rated 5 out of 5 by from Good battery I recently bought an EGO power + 20 inch mower kit with the rapid charger and 4 amp hour battery. It was my first time using an electric mower. I have a 1/4 acre lot and was able to cut my entire yard on a single charge, even with a particularly overgrown spot in my front yard. I would recommend the battery to others.
