Makita 18V 5.0Ah Li-Ion Battery | Bl1850b

When it comes to Batteries what we are looking for is runtime, power output and recharge time. These three elements of a battery can make a big difference to your tools and the work you're doing. The Makita BL1850 18v 5.0Ah Li-Ion battery gives you 66% extra runtime than the 3.0Ah smaller brother. The power output from the 5.0Ah battery is consistent and noticeably greater than that of the 3.0 or 4.0Ah, whilst delivering that stronger power output and longer runtime we were also impressed by a short recharge time of only 45 minutes. The BL1850 5.0Ah Battery is designed easy slide-on mechanism for attaching to your tools.
