Bosch battery charger C40-Li 5A 6V/12V — LiFePO4 & Lead‑Acid, IP65 weatherproof

The BOSCH C40-Li is a compact, weatherproof 5A charger and maintainer for 6V/12V lead‑acid and 12V LiFePO4 batteries, designed to recharge, maintain, and regenerate batteries for cars, motorcycles, boats and seasonal vehicles.

Keeping batteries healthy prevents unexpected no‑starts and extends service life for vehicles that sit idle or see short trips. Bosch engineered the C40‑Li to support a wide range of battery chemistries — from conventional flooded lead‑acid to AGM, GEL, EFB and 12V lithium‑ion (LiFePO4) — while adding protection and user convenience for home and workshop use.

Which battery types and vehicle classes does this charger support?

The C40‑Li covers multiple battery technologies and vehicle sizes so one unit works for many applications. It charges and maintains 6V and 12V lead‑acid variants and 12V LiFePO4 batteries, making it suitable for motorcycles up to cars and small boats.

• Compatible chemistries: flooded lead‑acid, AGM, GEL, EFB, SLI, and LiFePO4 (12V)
• Voltage range: 6V and 12V modes for lead‑acid; dedicated 12V lithium mode
• Typical vehicles: scooters, motorcycles, cars, SUVs, vans, light trucks, and motorboats

How fast and intelligent is the charging process?

The charger delivers up to 5 amps in lithium and motorcycle modes and uses a built‑in microprocessor to manage charging phases. That intelligence shortens effective charge time while switching to maintenance when full charge is reached to avoid overcharging.

• Maximum charging current: up to 5 A for lithium modes
• Microprocessor control: optimizes charge curve and reduces charge time
• Mode memory: restores the last selected charging mode after brief power interruptions

What safety and durability features protect the battery and charger?

Safety systems guard both the battery and the device from common faults and environmental exposure. The C40‑Li includes protections against overheating, short circuits and reversed polarity, and its IP65 rating defends against splashes and dust — suitable for garage or outdoor use.

• Electrical safeguards: short‑circuit and reverse polarity protection
• Thermal protection: prevents overheating during extended operation
• Ruggedness: IP65 splash and dust resistance for reliable use in varied conditions

What accessories and maintenance modes are included?

Bosch supplies practical accessories so the charger is ready to use and easy to store. Besides standard clamps, the unit offers maintenance and regeneration functions aimed at reversing discharge effects in seasonally used batteries.

• Included: cable with eyelets, removable clamps, wall‑mount hook, soft storage bag, and instructions
• Maintenance modes: long‑term trickle/float charging to sustain batteries during storage
• Regeneration: recovery routines to help revive discharged batteries from prolonged inactivity

Who is this for: The BOSCH C40‑Li suits vehicle owners who need a single, dependable charger for multiple battery chemistries — especially those with seasonal vehicles (motorcycles, classic cars, boats) or fleets that undergo frequent short trips. It’s also a good choice for home mechanics who want a compact, durable charger with built‑in safety features and simple operation.
