Review: Great upgrade from original small battery!! - Great upgrade from the original small battery. I do robotic installations almost weekly all over the US and Canada, one original battery would last me an install, usually two whole days, but, if I had to drill extra holes, then I would have to charge it (not a big deal at all since it only takes about 15 to 20minutes max to charge 100%). With this big boy, not only it would last me for the whole workweek but, you also get a lot more torque so careful if you use the impact drill! -as ai do- It will be more powerfull, but nothing "uncontrolable" if you are a pro. To charge it from dead to 100% takes about 45 mins to an hour, so on the third day when I go to lunch I just leave it charging and that will be more than enough, with no down time due to the drill at all. So, if you want a more "dependable" battery life and more output power, this is it. Since I was not used to the led charge indicating bar, I barely use it and just go more by "feeling" and experience than pressing the little button to know how much charge still has... so I barely do that, specially since I know it will last me for a while. ***Note***if you are a road warrior: you might know this by now but I always test my drill as soon as I get to my Customer's facility cause it has happened that the drill gets activated while on the plane and by the time I land, the battery could be dead... to prevent this from happening probably about 95%, put the button for the drill direction in the middle, where the drill will not go forward or backwards when you press the trigger on it.
Review: It's Makita! - I bought this as a third spare since I've been doing a lot of housework. Great quality and life.

## Questions & Answers

**Q: is charger included ?**
A: Single Batteries are not usually sold with a charger, chargers are usually included when you buy the tool but can be bought seperately

**Q: Can i charge this battery on the 18v charger**
A: No you have to get a charger for that style battery

**Q: This battery is smaller than my older batteries.  will it still work.   i want to know before i open it.  also my older are 18v, so powerwise?**
A: 12v & 18v aren't the same

**Q: Works with ml-dc 502b ?**
A: Take the tool you want it to fit to the big box store with you.  If the battery will not slide easily into the tool iit is because it won't work!  I do mean if it does.t fit or does not slide easily, find another battery that will.
