Makita BL1830B Li-Ion Battery 3.0Ah 18V with Charge Indicator - Black

Key specs: 18V, 3.0Ah Li‑ion chemistry, built‑in LED charge indicator, compatible with Makita 18V LXT tools, fast‑charging capability (with a compatible charger), protection circuit for overload/overheat/over‑discharge, lightweight and durable design with shock‑absorbing construction.

To install: align the battery contacts with the tool’s contacts, slide the battery into the tool until you hear a click. To remove: press the release latch on the tool and pull the battery straight out. Always ensure the tool is off before inserting or removing the battery.

Yes. The BL1830B is designed for Makita’s 18V LXT lineup and works with a wide range of Makita 18V cordless tools. Always check the tool’s compatibility if you’re unsure.

It includes a built‑in protection circuit that helps prevent overload, overheating, and over‑discharge. For safety, avoid exposing the battery to moisture, extreme heat, or direct sunlight, and never attempt to disassemble it.

The LED indicator provides a quick read of remaining charge. When charging, the LEDs illuminate to show current charge level; when in use, the indicator can help you gauge remaining runtime. A fully charged battery typically shows the highest LED level.

The BL1840B has a higher capacity (4.0Ah) than the BL1830B’s 3.0Ah, offering longer runtime under similar use. If you frequently run power‑hungry tools or want longer uninterrupted work, the BL1840B is the stronger choice. See: https://fepy.com/product/makita-bl1840b-4-0ah-18v-lithium-ion-battery

The BL1850B provides even longer runtime due to its 5.0Ah capacity, with a small increase in weight. It’s ideal for extended sessions with high‑demand tools. See: https://fepy.com/product/makita-bl1850b-5-0ah-18v-lithium-ion-battery

The BL1815 has a smaller 1.5Ah capacity, offering lighter weight and shorter runtime. The BL1830B provides roughly double the runtime for similar tool usage, making it better for longer tasks. See: https://fepy.com/product/makita-bl1815-1-5ah-18v-lithium-ion-battery

This battery is well-suited for professionals and DIY enthusiasts using Makita 18V LXT cordless tools such as drills, impact drivers, saws, and grinders. It balances portability with reliable runtime for day‑to‑day tasks and mid‑scale projects.

Use a compatible Makita 18V charger to achieve best results. The BL1830B is designed for fast charging with appropriate chargers, and typically reaches a full charge in roughly 22 minutes under the right charger conditions. Avoid charging unattended in extreme heat or directly after heavy use until the battery cools.

Store the battery in a cool, dry place at around 20–25°C (68–77°F). If not used for an extended period, store at roughly 40–60% charge. Avoid high temperatures, moisture, and deep discharges. Clean contacts periodically and recharge before long-term storage to maintain performance.
