Abaige Upgrade

These batteries seem to have good life and fit properly in both my 12 yr. old Black&Decker charger and leaf blower.

The package arrived exactly when they said it would and the batteries were just what I needed. Would highly recommend.

I put these in an older Black & Decker leaf blower. They worked well and have me more fun time.

I should have known from the weight of these batteries that no way would they be 4000mAh as rated. I have used them twice and when they only lasted 5 minutes in my B&D hedge trimmer the first time I used them I just figured they may not have charged all the way so I didn't return them. I SHOULD have. They last 6 minutes tops and am requesting replacement under warranty. I will update if the company honors their warranty. As it stands now do not buy these batteries.Update: I have changed my initial 1 star rating to 3 because the seller did honor their warranty and is sending me new ones after concluding that I may have received a defective batch. Great customer service, no hassle. I will re-evaluate the replacement ones on their performance and update.

Great replacement for old B&D batteries. Very good price and hopefully over time will be a dependable product!

The buying experience was amazing. Received batteries the very next day after ordering. It seems as though batteries get weak after about 7-8 minutes of use on my blower, which is about half the expected length.This was something I was just going to live with. Most companies make returns and exchanges a nightmare. HOWEVER!...without even contacting them, I received an email from them in which they were extremely kind and eager to take care of this issue. They explained the batteries begin to assume a full charge after about the third cycle or so. They then offered to replace them. I told them not to send any replacements unless after the third or so charging cycle the batteries still didn't last. I just received another email and replacements are already on the way.THIS IS THE WAY CUSTOMER SERVICE USED TO BE!!! I will definitely be doing business with them again! A big shout out to NinsoneUS. If I could rate them with 20 stars, I would do it.

Went with the upgraded power capacity, but while it works well, I seem to lose power pretty quickly. I use these with both my weed eater and a blower, with same results. My yard is not that big, but I have to carry both around to be able to do the job. Seems to be built pretty well. Good enough for the money, but wish they held more of a charge
