Bonacell 12V 2000mAh Lithium ion Replacement Battery Comaptible with Rockwell RW9300 WA3503 WA3504 WA3505 Power Tools

Was a little skeptical that everything was going to fit correctly, but glad I bought these (got 2 of them). They snap right into the Rockwell charger perfectly, charge quickly, and hold a charge well. I've been using my screwdriver for a few days taking things down (we're moving) and I'm still on the first battery. Great job guys, and great price.

The battery does not fit snugly into the Rockwell. After repeatedly using it and holding it in place, eventually I used it on a ceiling. It fell out, crashed to the floor and broke. Complete waste of money.

I'm always hesitant buying a product that isn't the same brand as what I'm replacing, but luckily this worked just fine! I purchased this for my Rockwell drill and so far no issues.

Out of two batteries, the tabs that hold the battery in broke off on one of them the first time it was inserted into the tool, so it wouldn't stay in. The second battery broke the third time it was inserted into the tool. The two times that the battery did not break, it only ran about a third as long as the old original battery.

Difficult to fit into charger, may need to file it a little on the clips to make it easier. It does fit, although have to push it in very hard. Appears to hold a charge although I haven't had it long enough yet to advise how well.

After trying to charge several times on the Rockwell charger, the battery does not hold a charge. It never charged once after receiving it. I've confirmed that the model number is accurate and should be compatible with the charger.Unfortunately the return window has passed, otherwise I would return and ask for a refund.

I love this generation of Rockwell tools. Fully charged battery, taken lifted charger, inserted into impact... will only put three rack screws in before the guide light flashes indicating low battery. If there is a savior for these tools...this is not the battery.

Batteries took a charge properly and seem to work as well as the ORM Rockwell batteries. Time will tell if they hold up to repeated charging but so far I’m perfectly satisfied. Will adjust to 5 stars if they are still holding up to occasional use after a few months.
