Overview
A microprocessor-controlled charge cycle runs this CTEK charger automatically once you connect and select a mode, then holds the battery at full for storage. Desulphation and a recondition mode help revive sulphated lead-acid batteries, and temperature sensing adjusts voltage to the weather.
Set-and-forget maintenance for cars, motorcycles and stored vehicles is what it does well, with lithium support added. The output is modest, so a very large, deeply flat battery will take a long time.
Who it's for
Seasonal vehicles, garages and service bays keeping batteries healthy are the target. Drivers who need a start right away should carry a jump starter instead.
Pros and cons
- Fully automatic charging
- Supports lithium and lead-acid
- Recondition and desulphation modes
- Extension cable and bumper included
- Modest output for big batteries
- Not a jump starter
Performance notes
Charging follows an automatic multi-stage cycle, so the charger tapers current as the battery fills and then maintains it without overcharging. Temperature compensation raises or lowers voltage with ambient conditions, which protects batteries in cold garages and hot sheds.
