Having a newer vehicle with a new type of battery can be a bit nerve wracking at times, the cost of replacing one would set you back over $1000 so you want to be sure you're taking good care of it. Normal trickle charges work ok but they don't have the technology to properly care for and extend the life of a battery. This CTek charger is the perfect choice for not only preserving the battery's life during long periods of non-usage, but also to help restore and maintain full functionality of your battery over time. For instance the CTek Lithium charger has an eight step charging system which tests battery condition, charges, and then maintains optimal capacity in the battery without overcharging. Their technology is so advanced that several top car manufacturers (Ferrari, Porsche, Mclaren, etc) use CTek as their factory battery chargers. Add a 5-Year warranty on top of all that and you've got your best choice for battery charging and protection.

Battery Charging Stages:

Step 1: Test

Tests for battery defects so in the event of a defective battery charging is halted.

Step 2: Bulk Charging

Charges the battery normally up to around 90%. After this cycle it is safe to start your car in case you're late for an important meeting or event.

Step 3: Absorption

Charges the battery slowly up to 95% capacity with a reduced current.

Step 4: Analysis

Checks if the battery can hold the charge. If the battery can't maintain capacity at this stage you will probably need to replace it soon.

Step 5: Completion

Final charge stage with reduced current.

Step 6: Maximization

Final charge with maximum voltage up to 100% capacity.

Step 7: Float charge

Keeps the voltage in the battery topped up so it will maintain 100% capacity over the course of about a week and a half.

Step 8: Pulse Charge

Maintains and prolongs the life of the battery during long periods of inactivity. This is especially good for winter months when your sports car is tucked away. This step keeps your battery just below 100% so the capacity is preserved but without risking overcharging.
