Bosch C80-Li Battery Charger – 15 Amps with Trickle Function for 6V/12V Lead‑acid and 12V LiFePO4
Product description
What it is
The Bosch C80-Li is a versatile 12V battery charger designed for a range of lead‑acid chemistries (AGM, EFB, GEL, SLI) and LiFePO4 (12V) batteries, including 2Ah up to 400Ah capacities. It also offers a Quick mode delivering up to 20A and a power supply function to keep vehicle settings intact while you replace a battery.
How it works
Built around a microprocessor, the charger aims to optimise charging time and safety. If power is interrupted, a memory function saves the last setting and resumes charging when supply returns. It features trickle charging and regenerative functions intended to extend battery life and handle seasonal storage. A wake‑up function helps initiate charging for deeply discharged batteries (0.5V to 3.75V).
What matters most
On the safety front, it includes overheating and short‑circuit protection, protection against reversed polarity, and an IP65 rating for dust and splash resistance, which can be useful for workshop or outdoor use. The unit ships with a UK plug and comes with a hook mount, power cord, clamps, an additional eyelet cable, and a carrying pouch for easy transport.
Who it’s for
If you own a mix of vehicles or devices that use 6V/12V lead‑acid or 12V LiFePO4 batteries, this charger could cover most common needs—from cars and motorcycles to vans or motorhomes. It’s particularly practical if you value a memory function to preserve previous settings after a power cut and want a charger capable of long‑term maintenance without user intervention.
What it isn’t perfect for
The description suggests broad compatibility, but the real test is whether the charger’s presets align with your specific battery brand and chemistry. For deeply discharged batteries, the wake‑up feature helps, yet if your typical battery falls outside the 2Ah–400Ah range or uses a non‑listed chemistry, you may need a dedicated solution. Also, while the IP65 rating is solid for many environments, it doesn’t guarantee all‑weather protection in extreme conditions.
When it makes sense to buy
Consider this charger if you prioritise multi‑chemistry support, a built‑in memory for power outages, and a mixture of fast and maintenance charging with a compact, UK‑plug‑ready package. It can be a pragmatic choice for workshops, households with several vehicles, and seasonal storage where trickle charging is desirable to extend battery life.
Before you buy, check these points
- Confirm your battery type and capacity fall within 2Ah–400Ah and are among the supported chemistries.
- Ensure the charger’s 20A Quick mode aligns with your usual charging needs and vehicle electrical systems.
- Verify your installation space allows for the hook mount and cable lengths supplied, plus the IP65 rating suits your environment.
- Review whether you need the wake‑up function for deeply discharged batteries in your use cases.
Practical use and comparisons
In practice, this Bosch charger sits between basic lead‑acid maintainers and more feature‑rich versatile models. If you mainly deal with standard 12V lead‑acid batteries and occasional LiFePO4, it offers a sensible balance of speed and safety. If you require precise, manual control over charging stages or higher amperage for large battery banks, you might explore alternatives with more granular control, though at a different price point.
FAQ snapshot
- Does it support LiFePO4 batteries? Yes, it supports 12V LiFePO4.
- What is the range of battery capacities? 2Ah up to 400Ah.
- Is it safe for stored batteries during winter? It includes trickle and regenerative functions, designed for long‑term maintenance.
Final verdict
Final verdict: worthwhile if you need flexible, multi‑chemistry charging with maintenance features and a cautious safety profile in everyday use. It’s not necessarily the best fit if you require highly custom charging profiles or operate outside the listed battery ranges.
Is it worth it?
Worth considering if you value a practical, all‑round charger with memory for power outages and a robust safety suite, it offers useful features for regular vehicle maintenance without being overly complex.
