Description

Makita 18V LXT Lithium-Ion batteries charge faster and work longer than standard Lithium-Ion batteries, giving you and your Makita cordless tools unmatched performance and productivity for demanding applications. The Makita 3.0Ah battery (BL1830B) has a category-leading charge time of only 30 minutes, so it spends more time working and less time sitting on the charger. It also features an L.E.D. Charge level indicator to monitor battery charge. Makita is the innovation leader in cordless tool technology and has the world’s cordless tool line-up powered by 18V Lithium-Ion slide-style batteries. The BL1830B is compatible only with Star protection tools, indicated by the Star symbol and/or yellow battery receiver under the tool. Makita 18V Lithium-Ion batteries resist self-discharge so they're ready for use even after long periods of storage. The Rapid optimum charger (sold separately) is a smart- charging system that communicates with the battery during charging to monitor current, voltage and temperature. This helps optimize battery life and deliver a faster charge. The charger has a built-in fan to cool the battery for faster and more efficient charging.

    • Works with older tools
Style: 3.0Ah Battery, 1-Pk
Despite what the description says, I was informed by Makita customer service that this battery (and only this battery) is compatible with the older tools that do not have the Star Symbol or yellow battery receivers. After getting only a few minutes of charge out of the old batteries, it was nice to be able to work for over an hour and still have plenty of charge left. ... show more

    • Reliable Battery with Solid Runtime
Style: 3.0Ah Battery, 2-Pk
The Makita BL1830B-2 18V LXT 3.0Ah batteries are dependable power sources for Makita cordless tools. They provide consistent performance and a good balance between runtime and weight, making them practical for everyday use. The compact size makes them lighter to handle compared to higher-capacity options, which helps reduce fatigue during longer projects. Each battery includes a built-in LED charge level indicator, so it’s easy to check how much power you have left before starting a task. They charge quickly and hold up well over repeated use, though they don’t run as long as the larger 4.0Ah or 5.0Ah versions. For users who already rely on Makita’s 18V LXT system, these are reliable and convenient additions. Pros: They are lightweight and easy to handle, provide dependable power for most tasks, and recharge quickly with an LXT charger. Cons: The runtime is shorter compared to higher-capacity batteries, they are sold at a premium price, and they’re only compatible with Makita’s 18V line. A solid and reliable battery pack that keeps Makita tools running smoothly. The 3.0Ah size is a good balance of weight, charging speed, and power for everyday projects. ... show more

    • Works With All Makita Tools, Old or New, Start or No Star
Style: 3.0Ah Battery, 2-Pk
Despite what the seller states, these batteries work with any Makita tool whether or not it is a Star Protection tool. I have an older 1/2" Makita Drill that has neither a star symbol nor yellow plastic battery receiver. I called Makita tech support and asked what batteries to use for my drill as the BL-1830 batteries are no longer available. I was told that the BL-1830B batteries would work fine, just that the charge indicator (AKA, Gas Gauge) would not work on my older drill that lacked a star symbol. I was told that the "B" in BL-1830B batteries stands for "Bridge Battery" indicating that it will bridge between the old and new (Star Protection and Non-Start Protection) tools and will work with any tool or charger that I used with the BL-1830 batteries. The BL-1830B batteries do charge fine on my old charger. The lack of a charge state indicator is not an issue for me as my old BL-1830 batteries didn't have one anyway. These batteries are not cheap but work well. I deducted one star on this review because of the confusing statement on the product description. ... show more
