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.

My Dog Loves this!
Color: Blue T-Bone, Size: 1 Count, Color: Blue T-Bone, Size: 1 Count
My dog loves her Nubbies! My Dog chews her Nubbie every morning after she has her breakfast. She sometimes wants my husband or I to hold it for her while she chews on it. I think it is really good for her teeth and gums. These last a few months for our dog who chews it every morning. After a few months the edges get a little rough from all the chewing so I throw it out and replace with a new one. These are very reasonably priced, so I always have a fresh one ready to go. She gets very excited when we get a new one out of the package..

Pups like them
Size: 4 Inch (Pack of 2)
It took a little bit but once my dogs started chewing on them they seem to like them. They're holding up pretty well and not destroying them too quickly like they did some other chews.
