CTEK Named Best RV Battery Charger

RV Expertise, an online resource for RVs, travel trailers, and 5th wheels, recently named CTEK’s MUS 4.3 as the “Best RV Battery Charger of 2020.”

The MUS 4.3 TEST & CHARGE charges 12-volt lead-acid batteries (Wet, MF, AGM, GEL). RV Expertise called the MUS 4.3 “the overall best charger on the market.”

They wrote, “The patented eight-step process will maximize the performance of your battery, as well as prolong the overall lifespan. The process includes a desulfation step that removes any sulfate from lead plates. The reconditioning step also helps extremely discharged batteries.”

CTEK is focused on safety, both for the user and the battery, and the MUS 4.3 TEST & CHARGE is safe and easy to use. The charger offers user safety through spark-free operation and reverse polarity protection.

The vehicle is protected by exceptionally clean voltage and current delivery with no surges or spikes. As a result, there’s no need to disconnect the battery from the vehicle while charging.

“The safety features are what offer the customer such great peace of mind,” said RV Expertise. “The safety features are also a large part of why this is the best charger on the market.”

The MUS 4.3 TEST & CHARGE has a patented 8-step program that tests the battery condition and revives, charges and maintains to ensure maximum battery life and performance. 

The RECOND mode recovers deeply discharged and stratified batteries, while the FLOAT/PULSE maintenance mode ensures ideal battery care during periods of inactivity.

“The patented maintenance process is one of the greatest benefits this charger offers,” said the reviewers at RV Expertise. “... the LED display will allow you to monitor the full charging process, which helps limit the chances of overcharging. You’ll also have peace of mind as this charger has plenty of safety features to protect you and ensure the overall effectiveness of the device.”

In addition to vehicle chargers, CTEK offers its DC/DC onboard charging solution, featuring the D250SE and the SMARTPASS 120S.
