Customer Reviews on Makita BL1830-2 18-Volt 3.0 AH Battery

These are my 5th and 6th batteries. One and four died withen the first two years contrary to the extended service life that manufacturer markets them as. Two things to remember do not use these when they are hot and do Not run them down like we use to with ni cad batteries. Li-ion batteries have no memory except if you mistreat them. If they get hot or too low on power they will be very short lived. The charger does a great job of cooling them down and charging them up. Leaving them on the charger till the fan turns off seems to be the best way to keep them alive longer. Feel free to just rotate them onto the charger all the time. Infact keep one on the charger all the time and you will get max life and best use out of these power tool batteries. Once the battery’s energy lvl is visibly slowed or sounds slow throw them on the charger. Also if you’re going to store them for a weekend or a month make sure they are fully charged they really like to be charged up and kept cool. leaving them in the sun is also very bad. Heat = death of a $70 dollar power tool battery.

I was using the much smaller 1.0ah batts that came with the tool, and they’d last less than an hour.

This 3.0ah is so much better and lasts for a good couple of hours (having 2 is also great). Plenty of torque, super-fast recharging time and THE CAPACITY TO GET THINGS DONE.

Also, the Lithium technology is far superior to NiCd (and even NiMh); smaller, lighter, no degrading capacity (memory) effect, stronger torque, faster recharge and longer lasting.
