Before trying any of your Worx tools, take a moment to confirm their compatible batteries. You might insert the battery into a string trimmer only to discover it doesn’t power up. Or perhaps it’s not seating correcty into the connection points.
Don’t assume it’s a bad or dead battery. Take a close look at the connection points as they may not be obvious.
Just make sure you check out the specs and see if what’s being said are factual.
Understanding Battery Pin Differences
The Worx 20V batteries come in two separate family. They makes both a 6-pin and 4-pin battery. So these batteries appear alike but cannot be swapped.
Take a look at a WA3551 battery compared to WA3575 one. Notice how there is four pins on the WA3551? And the WA3575 has six metal pins on its bottom.
That’s a big distinction.
What about charging on a charger? Can it do both battery types?
For example, you may look at a dual-bay charger and see that there is six pins in the contact bay. Will a 4-pin battery fit into that bay and charge? Probably not. The number of pins are important for delivering power.
So go ahead and try it out just to make certain.
Take the 6-pin WA3575, plug it in the charger and test it. It fits right into place and the lights comes on at once. Solid status indicator. So far it was charging properly. That tells us that this charger has been made specificly for the 6 pin units.
No it won’t.
Check for tool compatibility too. Grab a cordless drill and check the battery type it take. The WA3551 4-pin battery will not work. The battery simply does not fit into the drill.
There is no power whatsoever from the battery. It tell you this drill only runs off the 6-pin system.
Let’s go back to the string trimmer. This one is not compatible with the 6-pin WA3575. Physically it’s blocked from connecting.
Replace that battery with the 4-pin WA3551 instead. Fit it into place snugly and… Voilà… The trimmer spring to life. Lesson learned?
And you can’t just mix and match the batteries randomly. Some of your tools will only take a 4-pin battery; others requires 6-pin batteries.
The drill, and the charger? They’re in the 6-pin camp. And the trimmer? It’s a 4-pin camp. Check your manuals to confirm compatibility between your tool and battery.
That’s easily remedied.
The trick is to make sure you have the correct battery for the job. The number of pins is critical. Read the label on the battery before purchasing.
All Worx 20V batteries aren’t interchangeable. Don’t assume they are. It’s better to find out now than the hard way. You should of checked first.
