Makita 18V 4.0Ah Li-Ion LXT Battery BL1840B 196399-0 BL1840 Star Genuine UK

Product Information

Keep the batteries at around 60°F. Extreme cold will drain your rechargeable batteries. Never leave batteries in a vehicle or shed where they might freeze because this can cause permanent damage. NiCad batteries are more tolerant than NiMH, and while early Li-ion were susceptible, Makita’s LXT batteries handle the cold surprisingly well. This 6.0Ah battery will set new standards in run time, particularly when used on efficient brushless motor tools or in tandem on select Makita 'X2' - Twin 18v tools. Makita 18V X2 LXT (36V) cordless tools are powered by two 18V batteries, and are engineered to deliver corded power and run time for select highest-demand tools like saws, blowers and trimmers – but without leaving the 18V battery platform or investing in heavier, high-voltage batteries. MAKITA 6AH BATTERY FEATURES Recharge batteries based on the type. There’s some confusion about whether you should let batteries run all the way down before recharging. It depends on the type. NiCad batteries have what’s called a “memory effect.” For example, if they’re still one-quarter charged when you recharge them, they “remember” that, and only provide a three-quarter charge. This effect gets worse each time, so they need to be “deep discharged” (run as flat as possible) before recharging. NiMH and Li-ion batteries don’t have the same problem, so you can recharge them whenever convenient, as soon as your tool isn’t working at peak performance. These batteries were discontinued in 2012 when Makita introduced the LXT line. The LXT batteries are based on Li-ion technology, which is more efficient and more powerful than NiCd technology. They are also smaller and lighter than the yellow connector batteries. Recharge time for the BL1850B 5.0Ah battery is just 45 minutes when using a Makita DC18RC or DC18RA fast charger. This compares with 22 minutes for the popular 3.0Ah 18v Makita Li-ion battery or 36 minutes for the 4.0Ah Li-ion battery. The battery capacity indicator LED's which show you how much power you have left at the touch of a button.

Don’t overcharge the batteries. Overcharging can dramatically reduce the performance of your batteries, particularly NiCd and NiMH types. A short while won’t make much difference, but don’t leave batteries in the charger for any longer than necessary after they’ve reached full charge. Some Makita batteries have circuitry to prevent overcharging, but it’s best not put it to the test. Makita’s Lithium-ion Extreme Technology (LXT) batteries have useful charge indicators. Compatible with 18v tools if they have a star on the connector plate or if they have a yellow connector plate The new Makita 2.0Ah battery with a 30 minute fast charge time with a DC10SB charger or 70 minute standard charge time with a DC10WD charger.Charge times: 14.4/18V 3.0Ah battery in 60 mins 18V 4.0Ah battery in 90 mins 18V 5.0Ah battery in 110 mins Don’t store drained batteries. If you’re storing batteries for any length of time, don’t leave them with no charge because they may not “wake up” when you want to charge them again. Experts recommend charging to about 50%. Makita’s LXT batteries, for example, are supplied with 30% charge, which is “for storage purposes only.” With NiCd and NiMH batteries, the power starts fading away the minute you start using it. That doesn’t sound particularly bad, but in reality you’re almost never getting peak performance. With Li-ion batteries, though the eventual drop-off is more dramatic, they deliver consistent power for longer. Equipped with Star Protection Computer Controls™ to protect against overloading, over-discharging and over-heating

In practical terms, a 3.0 Ah battery delivers the same performance as a 2.0 Ah battery in terms of outright power — voltage output — but it will continue to deliver that power for longer. It’s like having three gallons of gas in the tank instead of two. The yellow connector batteries were first introduced in 2004 and were the first 18V batteries available from Makita. They were based on NiCd technology, which is less efficient and less powerful than the Li-ion technology used in the LXT batteries. They were also larger and heavier than LXT ones. The Li-ion range delivers 430% more working capacity during its lifetime compared to Ni-Cad and is 40% Lighter than Ni-MH. The 18V LXT® 5.0Ah battery is compatible only with Star Protection tools, indicated by the Star Symbol™ and/or Yellow Battery Receiver under the tool.

The Makita 18V LXT® Lithium-Ion battery charges faster and works longer than standard lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 5.0Ah battery has a category-leading charge time of only 45 minutes, so it spends more time working and less time sitting on the charger. The new Makita 1.5Ah battery with a 22 minute fast charge time with a DC10SB charger or 50 minute standard charge time with a DC10WD charger

Where uninterrupted run time is critical, such as on remote construction locations or where charging capacity is distant and would mean valuable time lost away from the operating point, extended run time is all important. The Makita BL1850B 5.0Ah 18v Li-ion battery provides 66% more run time than that of the 3.0Ah battery whilst maintaining the same size and weight so maintaining the excellent balance and comfort of a Makita tool in use. The new battery is engineered to give more run time (twice the run time of the Makita 3.0Ah LXT battery), but with the same weight and dimensions as the lower-capacity 3.0Ah, 4.0Ah, and 5.0Ah LXT batteries. It reaches a full charge in only 55 minutes (with DC18RC / DC18RD fast chargers), the fastest charge time in its category. Includes a battery capacity indicator LED so you know how much charge is left. Having tried quite a few different copy makes of the Makita battery . I have come to the conclusion the Makita battery are much better performance wise.

Charge times: 14.4/18V 3.0Ah battery in 22 mins 18V 4.0Ah battery in 36 mins 18V 5.0Ah battery in 45 mins Makita technology delivers category-leading charge time so the battery spends more time working and less time sitting on the charger (charger not included)
