*) Back current drain refers to the current that drains the battery if the charger is not connected to the mains. CTEK chargers have a very low back current. **) The quality of the charging voltage and charging current is crucial. High current ripple can heat up the battery, accelerating the aging process of the positive electrode. High voltage ripple may harm other equipment connected to the battery. CTEK battery chargers produce clean voltage and current with low ripple.
 
Important Considerations Before Purchasing a CTEK Charger:
1. Battery lifespan under 2 years: If your car battery is less than 2 years old, the CTEK charger might be able to charge it, depending on its current voltage. However, the overall condition of the battery will determine whether it can be fully revived.
2. Battery voltage 2 volts and above: The CTEK charger operates effectively when the battery voltage is at or above 2 volts. If the voltage drops below 2 volts, and especially if it's between 0-2 volts, the Battery Management System (BMS) may lock the battery to prevent further discharge and damage. In such cases, the CTEK charger is unlikely to charge the battery due to the BMS lock. To avoid this issue, make sure to charge your battery before it reaches such a low voltage. If the battery is locked, only a professional may be able to unlock it, though success is not guaranteed. Pre-charging by a professional may be required before using the CTEK charger.
3. CTEK charger limitations: While the CTEK charger can help extend your battery’s life, it may not be able to revive a battery that can no longer accept a charge or hold a charge anymore. If the charger detects issues such as very low voltage or significant battery deterioration, it will display a red LED warning light, indicating that the battery may require professional attention or replacement, as it might be beyond recovery.

One of the best minimalist case I have tried for the S24 Ultra. Very good fit and covers the device al around. The added texture of the case makes it feel nice to hold and it gives good grip. Definitely a good purchase.

Pleased with this item.
Firstly the plus points... Very sleek n classy design. Lovely color too.
Easy to grip... Fits my palm perfectly. The torchlight is very handy n bright too 👍
OK. I find the little fan to be a tad heavy.
Also sounds quite noisy when I increase to 80 n above.
But overall, I'm still pleased with my purchase.
