Plug & Play
The operation is simple and charging will commence upon connection. With no need to disconnect the battery from the vehicle, at charge start the LITHIUM US will automatically reset any low voltage protection electronics (Battery Management System) fitted. Charging can be restarted manually at any time using the ‘Reset’ button.
Fully Automatic
The CTEK LITHIUM US is a fully automatic ‘connect and forget’ charger with 8 charging steps including a testing sequence to show if the LiFePO4 battery can take and retain the charge, a unique maximization step to restore full capacity, and patented maintenance charging to ensure maximum performance even after months of inactivity. Splash-proof and dust-proof (IP65) the LITHIUM US is easy and safe to use, protects vehicle electronics, is spark-free, is reverse polarity protected and short circuit proof. The LITHIUM US features a 5-year warranty.
8-Step Program
- Accept: Tests if the battery can accept charge. This step prevents that charging proceeds with a defect battery.
- Bulk: Charging with maximum current until approximately 90% battery capacity.
- Absorption: Charging with declining current to maximize up to 95% battery capacity.
- Analyze: Tests if the battery can hold charge. Batteries that can not hold charge may need to be replaced.
- Completion: Final charge with reduced current.
- Maximization: Final charge with maximum voltage up to 100% battery capacity.
- Float: Maintaining the battery voltage at maximum level by providing a constant voltage charge.
- Pulse: Maintaining the battery at 95-100% capacity. The charger monitors the battery voltage and gives a pulse when necessary to keep the battery fully charged.

Nice kids shoes
Size: 3.5 Big Kid, Color: Blue
I bought 2 pairs, one for my son and one for my daughter. they seem to run a tad snug so size up at least one size.
My sons fit well right away, had to return and reorder my daughters pair, cause her size was too small, sized up twice and she now says they are super comfortable. They are proving to be fair sturdier than the other shoes I have bought them in the last year.
The colors are true to the photos. I find them rather stylish, and my kids can easily get them on and off..
I've not had to clean them.
