## Questions & Answers

**Q: Does this battery replace the 5.0 AH one I use with my lawnmower?**
A: I believed the seller that it would work. IT DOESN'T! DON'T BUY expecting it to work in your mower. Had to pay to ship it back and then was charged a 40 % RESTOCK FEE! Seller said it was to recoup shipping cost! HELLO? I PAID SHIPPING BACK! And it cost only $15!!!! 40 % of $130 is $52!!!!

RIP OFF!!! DON'T BUY!!!!!!

**Q: How long does 40v 2Ah batteries last between charges?**
A: If you are using them in a string trimmer or a hedge trimmer not very long - a few hours at best.  If they are just charged up and allowed to sit then serveral days.  I have three that I switch in and put back on the chargers.  Also, if a battery has been drained too far then the charger won't even recognize the battery and you have to give the battery a "tickle" charge so the charger will recognize it and charge it up.  If you observe the bottom edge of the battery you will see several pug-in points.  Connect the negative and positive plug in points to a car battery for a few minutes (doesn't need to be real long).  You may need to rig a thin piece of metal to use as a connector as the plug-in points are small.  In a few minutes you can successfully put the battery in the charger to finish charging.  Iusually leave them on the charger over night - but I don't think they need all that long

**Q: will a kobalt 80v 6ah battery work on a 40v 5.0ah mower ?**
A: no. It will not work. Also, its much larger in size.

**Q: why/ don't you display or show the product that are requested? if you don't  have them then say so!!!**
A: Yep
