BROMLEY 450

When designing, we prioritise durability, repairability, and replaceable components to extend product lifespan and reduce waste. Bromley 450 comes with an easily replaceable LFP battery¹, featuring adaptive charging technology that helps protect battery health over time. You can purchase replacement batteries at marshall.com.

¹ Bromley 450 uses a Lithium Iron Phosphate (LFP) battery, free from cobalt and with minimal nickel content (~0.25%). This reduces reliance on some critical raw materials linked to social and environmental challenges. Battery still contains lithium and other critical minerals. Compared to conventional Lithium-Ion (Li-ion) batteries, LFP offers a longer cycle life and enhanced safety, with a significantly lower risk of thermal runaway. The trade-off is that LFP technology is generally heavier and has lower energy density, which is why Li-ion remains common in devices where weight and compactness are key. For applications where durability and sustainability matter most, LFP is a strong choice. Please recycle old batteries and electronic products responsibly.

Bromley 450 contains 15% recycled material by weight¹, reducing the need for virgin resources. This helps minimise environmental and social impacts associated with raw material extraction and processing. Using recycled content also helps lower carbon emissions compared to producing virgin materials².

¹ Includes post-consumer recycled ABS, post-consumer recycled PC-ABS, pre-consumer recycled aluminum alloy, pre-consumer recycled praseodymium–neodymium (rare-earth elements), and post-consumer-recycled polyester. Calculations are based on total product weight, excluding accessories and packaging.

² Industry data indicates recycled materials generally have lower carbon footprint than virgin materials; actual reductions vary by material and process.
