## Questions & Answers

**Q: Are these oem makita batteries or after market batteries with the makita brand logo on it, logo looks odd small in size?**
A: I honestly had a similar concern when I purchased these, but I made a good gamble. these ARE without a doubt legitimate Makita Batteries. (I don't do after market) The label style tends to change ever so often, I think that is what accounts for the smaller label. I was quite pleased with my purchase of these batteries, work as well as all my other 5 amps do. best wishes.

**Q: Will the charger i use for my 3 amp makita batteries charge a 4 and 5 amp battery?**
A: Yes, as far as know they are all compatible. I've been charging mine for the last couple weeks without any trouble.

**Q: Will the charger I use for my 3 amp makita batteries charge a 4 and 5 amp battery?**
A: Yes. Works the same for all of them.

**Q: Is it worth to pay high price for makita battery instead of much cheaper alternatives?**
A: That is something you have to answer yourself, I have always bought the Makita branded batteries and haven't had any problems. I also wait and look for good buys on the Makita branded accessaries
