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.

Looks like someone may have ordered the wrong battery
Fits in my tools just as well as the batteries that came with the tools did. Came with 2 bars of charge. I bought one of the "used" offerings from warehouse deals. Looks like someone may have ordered the wrong battery, just an opened package. Nothing shady about it, official makita gear which I've had good luck with in the last year or so with my cxt drill/driver.

Twice the run time of the 2Ah
Good little battery my lights last twice as long as the 2Ah.Very expensive but if you need more run time this is what you need.

Great battery
It's a great upgrade from the 1.5 amp battery that comes with the drill set. I've had my makita set for about 2 years and I love them, except for the battery charge life I finally decided to purchase the 4 amp battery. I can see a mark improvement in the performance and torque of both the impact and the drill driver. Now all I'm waiting for is a fast charger for them that's the only thing that henders this battery and drill set. I recommend this battery for anyone who has this drill, I ordered it and I recieved it the next day great! I have decided to order a second battery to complete my set.

Il prodotto è ottimo e non poteva essere diversamente vista la marca. Questo vale anche per il venditore che non ha perso tempo ad inviare la spedizione. Consigliati entrambi.

La mejor opción para las herramientas de 12V de la línea Makita, ya que la que te suelen incluir con las herramientas es la de 2 Ampers y se descarga bastante rápido, ya que al arrancar las herramientas la batería, suele consumir bastante energía, por lo que está de 4 Ampers, te garantiza un mayor rendimiento durante el tiempo de trabajo de tu herramienta.
