Description
CTEK 12V Lithium US Smart Charger 4.3AThe LITHIUM US (CTEK Part No. 56 926) is an advanced microprocessor controlled charger specially designed to recharge and maintain the cells of Lithium Iron (LiFePO4) batteries maximizing their performance and lifespan. With up to 4. 3A of charge current available the LITHIUM US is extremely flexible and will charge LiFePO4 batteries from 5Ah to 60Ah and maintain up to 120Ah.(Choosing a Charger) Plug & Play The operation is simple and charging will
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.

Good quality, lotsa fun
Not easy to find a sturdy toy for a minipoodle that loves to play rough with his toy. He has not been able to break this into pieces and that feels reassuring that I don't have to worry about little pieces and choking. These things bounce funny and my boy loves playing with it

Necessary for a small dog.
These are great for a small dog! They can get their mouth around it unlike a round ball. My dog is obsessed with these.
They are great for making him love a new guest to the house. All they have to do is squeak and throw the toy and they have a new friend!

Great for little dogs but squeaker breaks too easily
My Maltese is about 4.5 pounds and absolutely loves these! He got very excited to play with it right away. The shape is like a slightly flattened ball which is great bc he can pick it up in his tiny mouth. It’s actually quite cute to see him run with it back to me. When you throw it, the way it bounces and rolls is very unpredictable, which I think adds to the fun. Sometimes my pup drops it while running back and it goes rolling or awkwardly bouncing away from him which causes him to get more excited to chase it and grab it again. It’s been a highly entertaining toy for almost a week straight. The only downside is that the squeaker in it isn’t very durable. After a few days of playing and chewing to squeak it himself, the squeaker barely makes any noise. My pup isn’t an aggressive chewer at all so if your dog is an aggressive chewer, the squeaker really will not last.

G for small dogs
My Havanese absolutely loves these small toys, which we refer to as pucks. They are the perfect size for him. His previous favorite was a small green pig, but ever since we purchased these for his second birthday, he has shown no interest in the pig. They are easy to throw and fit comfortably in his mouth. I plan to purchase more. I would not recommend for strong chewers. My only complaint is I wish they all had happy or crazy faces instead of angry or sad ones.
