Frequently Asked Questions
Why is the BL1860B the most popular Makita battery?
We have no sales data to say which Makita battery is most popular. The BL1860B is a 6.0Ah LXT pack with a charge level indicator; Makita also sells larger LXT packs, such as the BL1890 (9.0Ah) and BL18120 (12.0Ah). Makita UK says the LXT battery powers over 325 products.
How much runtime does a BL1860B provide?
Runtime depends on the tool and workload, and we have not tested it. A 6.0Ah pack holds twice the charge of a 3.0Ah BL1830.
Are third-party BL1860B batteries as good as genuine Makita?
We have not tested third-party packs against the BL1860B and hold no reliable performance or lifespan figures for them. UKCA or CE marks are the maker’s own declaration, so buy from a seller that names a UK importer and offers a warranty.
Can I use a BL1860B in older Makita LXT tools?
Yes. Makita LXT 18V packs share one slide-style fitting, and Makita describes LXT as one battery across 325+ tools. Check an older tool’s manual for the packs it lists.

Signs Your BL1860B Battery Needs Replacing
Lithium-ion batteries degrade naturally over time. Here are the key signs that your Makita BL1860B battery needs replacing:
- Rapid discharge: The battery drains noticeably faster than when it was new, even after a full charge. If a battery that once lasted an hour now dies in 20 minutes, capacity has degraded significantly.
- Charges but dies quickly under load: The battery appears to charge fully but shuts off within minutes when powering demanding tools. This indicates internal cell failure where the battery can no longer deliver sufficient current.
- Excessive heat during use or charging: While some warmth is normal, a battery that becomes uncomfortably hot during operation or on the charger has damaged cells. Excessive heat is both a symptom and a cause of further degradation.
- Physical swelling or damage: Any visible bulging, cracking, or deformation of the battery casing means the cells inside have failed. Stop using a swollen battery immediately and dispose of it safely at a recycling point.
- Charger error indicators: If your Makita charger flashes error lights or refuses to charge the battery entirely, it has detected a fault. Most modern chargers include diagnostic features that identify damaged batteries.
- Age: lithium-ion packs lose capacity with age and use. If an older pack’s runtime has clearly dropped, replacement is worthwhile.
OEM vs Third-Party Replacement Batteries
When replacing your Makita BL1860B, you have two main options: genuine Makita batteries or third-party compatible alternatives. Both will physically fit and power your tools, but there are meaningful differences worth considering.
| Factor | Genuine Makita | Third-Party Compatible |
|---|---|---|
| Typical Price | £40-80 | £20-45 |
| Cell Quality | Makita genuine pack | Varies by manufacturer |
| Warranty | Makita UK: 2 years for Li-ion batteries bought from 1 April 2025; batteries are not eligible for the 3-year registration extension | Varies by seller |
| Safety Certifications | Built and certified to Makita’s own standards, with UKCA/CE marking | Varies by seller. Markings such as UKCA or CE are the manufacturer’s own declaration, not independent proof of testing — check who the responsible manufacturer or importer is before buying |
| Expected Lifespan | Not published by Makita | Not published |
| Performance Consistency | Made for Makita 18V LXT tools | Compatible, slight variation possible |
Choose genuine Makita batteries if you use your tools professionally and depend on them for income: you get a pack Makita makes and supports, with a known warranty route.
Third-party batteries can suit homeowners and occasional users who want a lower cost; quality varies, so check the seller and warranty. You can often buy two third-party packs for the price of one genuine unit.
How to Get the Most from Your Replacement Battery
Follow these care tips to maximise the lifespan and performance of your new Makita BL1860B replacement battery:
- First use: charge a new pack fully before use.
- Storage: keep packs in a cool, dry place out of direct sunlight, and recharge before use after long storage.
- Charging temperature: Makita’s DC18RC manual says not to charge when the room temperature is below 10 °C or above 40 °C. Never leave batteries in a hot vehicle or in direct sunlight.
- After charging: Makita’s DC18RC manual says to remove the battery cartridge from the charger after charging.
- Use a Makita LXT charger that lists the pack: Makita’s DC18RC, DC18RD and DC18SD manuals list LXT packs including the BL1830B, BL1840B and BL1850B; the DC18RC manual says not to use it for other manufacturers’ batteries.
How we compile this guide
We cross-reference compatibility details against manufacturer specifications where available, official tool manuals, and the physical standards that govern fitment (bore sizes, arbor diameters, voltage platforms, connector types). We prioritise primary sources over retailer listings, flag anything we can’t confirm, and re-verify the data on a regular cycle. Where we give a buying recommendation, we tell you the reasoning — not just the link. More on our method →
