2 Pack 40 Volt MAX 3.0Ah LBXR36 Replacement Battery for Black&Decker LBX2040 LBXR36 LBX36 LBXR2036 40V Lithium Ion Batteries

I bought a two pack of 40 V batteries at soon as I receive them I like the first one in and it light green and so I charge it till a solid. And when I plugged in just had a red light but I left it on and it did not charge, when I emailed them they sent a new one right away and it was great. I highly recommend this seller!!

I use these batteries in my lawn mower. These batteries ran longer than the Black & Decker ones and are a lot cheaper.

I've ordered four of these. One didn't last as long as I thought it should, but I left it out overnight during a freeze. My bad. The other three are fine.

I just received these batteries about a week ago. It’s a bit early to provide an honest review. But so far they appear to be holding a charge very well. I just wrote a review on the Black & Decker charger. You may want to refer to that. This company has been in business for as long as I can remember. It has a trusted reputation. I feel confident that they build a above average product.

The batteries don’t hold a charge as long as the original black and decker batteries.

Bought the battery in November to replace an existing battery. The November battery is no longer working properly. When you place on the charger, the charger will flash red instead of green. When flashing red, the better will not recharge. This defect is what the original battery did as well. The November battery was put away for the winter and I just began using it again in April. Would think the battery should last longer than that.

Cheap made, didn't last 6 months

Good for use with the lawn mower for about a half hour
