FAQs
Why Choose the Makita BL1850B?
Whether you're replacing a worn battery or expanding your cordless setup, the Makita BL1850B offers the perfect balance of runtime, weight and charging speed. Its 5.0Ah capacity makes it one of the most popular batteries in the Makita LXT range, providing enough power for demanding trade applications while remaining compact and comfortable to use throughout the working day.
What is the difference between Makita BL1850 and BL1850B?
The "B" in BL1850B indicates that it's an updated version with the added charge level indicator. If you're buying a new Makita 18V 5.0Ah battery, you'll most likely find the BL1850B, as it's the more recent and readily available version.
What is the life expectancy of a Makita 18V battery?
It’s hard to say how long your Makita 18V battery will last, but there are things you can do to maximise the life span. Extreme heat or cold can shorten the batteries life. It's best to store them in a cool, dry place, ideally at around 40% charge. While there's no guaranteed lifespan, you can expect a battery to last for a few years with proper care.
What is the difference between a 4.0 Ah and a 5.0 Ah battery?
The main difference between a 4.0Ah and a 5.0Ah battery lies in their capacity, which directly affects the runtime of your tools. A 5.0Ah battery will provide about 25% more runtime than a 4.0Ah battery for the same tool and workload.
