Upgraded 3600mAh HPB18 Replacement Battery Compatible with Black and Decker 18V Battery HPB18 244760-00 A1718 FS18FL FSB18

I weighted until I had actually used the product an extended time before I reviewed it. That way I could write a real review, not one of those, "It seems to be okay" type of reviews that are relatively meaningless. Anyway...I am not a full time contractor. I do remodeling during the summer months only. If you are a 40-hour+ week contractor, this review might not apply to you, but then again, it might. All others... well read on, I think you will like this battery.It was delivered on Saturday March 30, 2019. That evening, I put it on the charger with the timer set for 6 hours (the minimum recommended charge). I intermittently used it (light duty hole drilling and screw driving) until the beginning of July. It was then that the heavy use began. I finished a pantry and bathroom remodel I had previously started. I drilled 44 pilot holes through a minimum of ¾" plaster and into wall joists and set 132 , 2 ¼" screws used to hold up the shelving system. After that was set up, I started screwing the cement board to the subfloor (maybe another 20 - 30 screws) when the battery required its second charge. I then had to switch to and finish with a corded drill driver before the mortar set. But... YES! All of this on only the first charge that I did way-y-y back on March 30th.Before, I placed it on the charger for only it's second time, I taped the trigger in to make the tool run with no load until the battery was totally dead (less than 10 minutes). Then, I put it on the charger again for another timed 10-hour recharge. Instructions say to only charge a totally dead battery; and to only charge it for a minimum of 6, but not more than 10 hours.Since then, I have attached 4 additional 3' x 5' cement boards to the floor. That is roughly 1 box plus about a ⅓ of another box of screws (each box has 185 screws). Plus I used it to salvage all of the screws out of an old washer and dryer that was going to the recyclers. The battery is still going strong.My tool is an original Black and Decker HPG 1800 drill driver. This battery fits perfectly into both the tool and the included battery charger.It is a "taller" battery, so it does add an small amount of additional weight when compared to the original battery. But it is not noticeable enough to discourage it use.If this battery ever dies, I will definitely buy another just like it. No complaints here. It is worth every penny.

Not an easy fit but worked with some effort to align and force pins

Doesn't last as long as name brand

There was some confusion about the 3 versus 2 connectors. My stuff has only 2 connectors. The good news is that this battery (with 3 connectors) works with my stuff. The thing that was a rate-it-only-four-stars problem was that IT APPEARS that the plastic tabs that divide the connectors were a little too tall for my stuff. The battery would not snap into my drill easily. I filed the divider tabs and put some silicon goo on them so it snaps into place better. That makes it OK, right?

I have a cordless lawn trimmer I bought probably 10 years ago, and the OEM battery is long past its useful life. This was a perfect replacement. No problems fitting it into the charger or into the battery compartment of the trimmer. It was totally plug-and-play. And it seems to hold a good charge: it got me through trimming and edging my entire yard without petering out.

Battery works like oem battery

Charge didn’t last very long!

This battery pack almost lasted 4 years. I am going to buy another one. Great that my tools still work. Great value and worked very well until all of a sudden, the battery doesn't hold a charge. But almost 4 years of use? C'mon that is GREAT for the price.
