Proper Seating Battery Issue

I recently purchased both the mower and 12 inch trimmer.  I wanted both batteries because I want to use the lighter weight battery in my mower because I have a bank that is a bit of a challenge.  However and this is my question: When I use the trimmer battery in the mower it does not seat itself well. Usually I get the typical green light, but then it turns yellow when I try to start it, or the light just goes out and I have to try seating it again.  Has anyone else had this problem?  I've not had this problem with the heavier battery that is standard with the mower.

Richard, I've used my 2Ah battery in my mower on several occasions and never had an issue. If your 2Ah battery works with no issue in the trimmer and the 4Ah battery works well with the mower, it's a mystery to me as to why you're having that problem!

Just out of sheer curiosity, does the 4Ah battery work well with the trimmer?

I guess there could be an issue with how you're installing the smaller battery in the mower, but I can't imagine how. If it's slid in properly on the guides and clicks firmly into place it should work fine.

The only thing that comes to mind is maybe there's some corrosion on the terminals? Are the terminals (contacts) clean in the mower's battery compartment? If that was the case you would think the issue would be present with both batteries, though...

I use the 2.0Ah battery with my mower at least part of the time nearly every single time I mow, twice per week. I have never had a single issue loading or using it. You do have to push down ever so slightly harder to get it fully inserted, as the smaller battery is lighter and gravity doesn't help as much, but I would say the difference is almost unnoticeable.

I would also say that the effort required to push and maneuver the mower is exactly the same with either battery, so unless you can cut your whole yard in 20 minutes, swapping out batteries is probably more work than any imperceivable improvement in maneuverability using the smaller battery.

Both are new, about two months. No corrosion.

This really makes me wonder if something is warped.  I can plug the 2 or 4ah battery into my mower without any difference.

If both fit in a different tool then I'm guessing it's more likely an issue with the mower than the battery. The only way I can think of that it could be a battery issue is if something were sticking out and hitting the bottom of the battery compartment in the mower, where it isn't enclosed to hit something in the handheld tool.

Being that the 2ah battery is smaller, it's got me puzzled too.  *shrug*

I wonder if the terminals inside the 2Ah battery somehow got opened up and are making intermittent contact? That still wouldn't explain why there's no issue using it on the trimmer though.

If your local Home Depot has a mower on display, you could probably try the battery in it to see if the problem is the mower or battery. The batteries in the blower, trimmer, mower, etc in the stores around me aren't secured in any way, but you might want to give someone working lawn and garden a heads up before taking one out to try yours.

I second taking the battery to a Home Depot with a display unit and trying it there.  I've never had a problem with the 2ah battery working in the mower.
