## Questions & Answers

**Q: what tools are required (just a screwdriver? hex? bit-size?)**
A: A small phillips (ph.0) screwdriver is all that is needed.  You will also need to keep track of the screw caps that hide the screws on the bottom of the laptop - just pry these out with small pointed tool (small slot screwdriver, pointed nail file, whatever).  Be advised that the new battery does not come with screws and the factory battery should have keepers (little plastic rings) that keep the screws from falling free of the battery.  It's easy to remove these and use them on the  new battery, just be careful not to lose them.

**Q: Where are the actual charge / discharge instructions?  Also the images included say 1000 cycles.  The details however say 500?**
A: BatteryMon battery does not include mounting screws, returned my battery. If details say 500 cycles, expect that at most, but one reviewer states battery lasted inly 8 months, so, so much for details. There are no charge/discharge instructions; you just get the battery.

**Q: ¿Esta batería rinde igual, mejor o peor que la original que trae de fábrica??**
A: En mi caso en particular está haciéndome el trabajo correctamente, mi equipo no lo compre nuevo. Lo adquirí renovado. Yo no tengo quejas con el trabajo que está haciendo funciona muy bien. Espero eso te sirva.

**Q: Is this replacement for hp elitebook 840 g3 business laptop 14"?**
A: Yes. It's fit for hp elitebook 840 g3. But our battery is without the screws. You need to use your original screws. This battery has 6 month warranty. If the item has any problems, please feel free to let us know .We will try our best to solve it. Thank you. Best regards
