Bosch C80‑Li battery charger 6V/12V — 20A fast charge, IP65 for Lead‑Acid & LiFePO4

The BOSCH C80-Li is a heavy-duty, IP65-rated charger that rapidly charges and maintains 6V and 12V lead‑acid and 12V LiFePO4 batteries with up to 20A fast‑charge capability.

Designed for seasonal vehicles, workshop use, and owners who need reliable battery care, the Bosch C80-Li combines high charging power with smart safety features and flexible maintenance modes. It supports a wide range of chemistries—lead‑acid, AGM, EFB, GEL, SLI and 12V LiFePO4—plus 6V lead‑acid batteries for motorcycles and compact engines. The unit is splash‑ and dust‑protected (IP65), includes protections for reversed polarity, overheating and short circuits, and is supplied with clamps, eyelet cables, a wall‑mount hook and a soft carry bag for easy storage and transport.

How quickly will the C80-Li restore a drained battery?

The C80‑Li delivers up to 20 amps in fast charge mode, so it restores capacity significantly faster than typical trickle chargers. Actual charging time depends on battery size, state of charge and chemistry.

• Fast charge up to 20 A for rapid recovery
• Microprocessor control adjusts current for efficient charging
• Automatic resume of last mode after brief power interruption

Which battery types and vehicles are compatible with the charger?

This charger works with most 12V battery chemistries and 6V lead‑acid batteries, making it suitable for cars, motorcycles, vans, trucks, SUVs and small boats. It supports specialized battery types used in modern vehicles as well as older lead‑acid systems.

• 12V LiFePO4 (lithium‑iron phosphate) and 12V lead‑acid variants
• AGM, EFB, GEL and SLI battery support for modern vehicles
• 6V lead‑acid compatibility for motorcycles and classic vehicles

What safety and durability features protect the battery and charger?

Bosch equipped the C80‑Li with multiple safeguards to protect both user and battery during charging. The device’s IP65 rating and built‑in protections reduce the risk of damage from common workshop conditions and improper connections.

• Overheating protection and short‑circuit prevention
• Reverse polarity detection to avoid damage from wrong connections
• IP65 splash‑ and dust‑resistant enclosure for outdoor or garage use

How can the C80-Li help with long-term battery maintenance?

The unit offers maintenance and power supply modes to preserve battery health during storage or service. Maintenance charging slows self‑discharge and lengthens usable battery life for seasonal vehicles, while Power Supply Mode keeps the vehicle’s electronics active during battery replacement.

• Maintenance charging for seasonal storage and prolonged lifespan
• Power Supply Mode retains vehicle settings while the battery is removed
• Memory of last selected mode for uninterrupted charging after brief power loss

Who is this for: the Bosch C80‑Li is aimed at DIY mechanics, garage owners, riders, boaters and car owners who need a versatile, fast and durable charger that covers multiple battery chemistries and sizes. It’s particularly useful for people who store vehicles for months, maintain fleets, or perform battery service and replacements while protecting vehicle electronics. If you need a portable, robust charger with smart controls and strong safety features, the C80‑Li is engineered to meet those requirements.
