## Description

## Key points

These Powarobor replacement batteries are a 2 pack of 18V lithium ion cells offering 5500mAh capacity each, intended as a cost effective alternative to worn Makita units. They aim to extend runtime on cordless power tools used around the workshop or site, and the integrated LED indicator helps you see remaining charge at a glance. The pack suits tradespeople and DIYers who need dependable runtime without paying for OEM premiums.

## Technical details

- Name: Powarobor replacement battery
- Type: Lithium ion
- Voltage: 18V
- Capacity: 5500mAh
- Quantity: 2 Pack

## Why it’s worth it

These batteries include a protection system that guards against overcharge, overdischarge, overheating and short circuits, which helps protect both the pack and the tool. There is no memory effect, so you can charge whenever convenient without degrading usable capacity according to the manufacturer. Keep in mind that third party batteries can vary in fit and performance between chargers and chargers listed in the compatibility range may require checking before first use.

## Who it’s for

It makes sense if you want extended runtime for drilling, driving or general site work at a lower cost than OEM options. You’ll like it if you regularly swap batteries during busy jobs and value a clear LED readout of remaining charge. If strict brand warranty or certified performance is essential, consider that these are replacement batteries rather than original manufacturer cells.

## Compatibility

Compatibility is stated with Makita models including BL1815 BL1830 BL1835 BL1840 BL1840B BL1845 BL1850 BL1850B BL1860 and chargers DC18RC DC18RD LXT-400 and related part numbers, but always check physical fit and charger model before purchase.

## Care & maintenance

Charge fully before first use and avoid storage at full charge for long periods to prolong life. Store in a cool dry place away from direct heat and monitor the LED indicator during bulk charging and use.
