3.5Ah 40-Volt MAX Lithium Battery Replacement for Black and Decker Lithium Max Battery LBXR36 LBX2040 LBXR2036 LST540 LCS1240 LBX1540 LST136W Cordless Power Tools

The batteries work great and are a great price.

The price was great for the product and revitalized an otherwise useless cordless drill as I could not find a battery for a price i felt was worth the cost.

I have a 30 year old DeWalt cordless drill that needed replacement batteries. These batteries fit and work well. I haven't had them long enough to tell you how long the batteries will last.

The batteries are a lot lighter than the original. You should charge both and keep them rotating if you’re working on a bigger job. The price is amazing and they fit my Black & Decker if you remember to maneuver them a tiny bit as you put them into the charger or the drill to get them to lock in. Phenomenal price.

It only last about 10 mins for me. Odd. I charged before use...my husband said it did the same for him but about 15 mins. The battery that are official black and decker still work and are much better but these should last much longer. I dont know what the deal is with these. If I get any different results I will update.

Good batteries in fact better than the ones that accompany the product

Excellent battery

I have an old black and decker cordless drill I had over 15 years now. The battery fits but not as tightly as the original did. It did not hold a full charge as long either. This is ok for now, but I', putting new cordless drill on my Christmas list.
