Before we go any further, let me assure you that this aftermarket replacement is just as good as the OEM (Original Equipment Manufacturer) battery that came with your power tool.  In fact this battery has advantages over the stock battery. Keep reading and you will see.
Okay, since you already know the brand you need is Makita and the voltage is 18, then we can move onto model number and part number as well as battery capacity.
When looking to replace any battery, you will need to find the power tool or device model number. But for a Makita this number is on the device and will look like this: Makita BL1830. The part number refers to the number on the actual battery and will look like this: BL1830. This aftermarket battery is also compatible with other models including BDA3502, BDF451 and BDF451Z.
When you are going to buy a replacement battery, you should look at the capacity of the battery. On the OEM 18v Makita lithium-ion battery you will get a battery capacity of only 1500 mAh (3.00 Ah). But on the aftermarket battery, the capacity has 100% more runtime, holding a charge double the time. This is important if you have jobs to finish and don't want to take time waiting for your battery to recharge.
Replacement batteries, especially for an 18v Makita lithium-ion battery, are easy to buy since you are now armed with the information above. With over 1500 batteries and many other brands besides Makita you are ready to get those unfinished jobs around the house completed!
