CTEK’s float and pulse maintenance modes are patented processes that keep batteries at 95-100% charge when connected over long periods without risk of overcharge damage. This is ideal for stored seasonal vehicles, classic cars, and powersports vehicles.

Global Safety Certifications

From CE marking to UL listing, CTEK chargers meet the most stringent safety standards worldwide. Extensive testing ensures their chargers won’t overcharge, overheat, or emit harmful EMF radiation even under faults.

Robust Industrial Build Quality

From the advanced microprocessors to molded housings and heavy duty cables, CTEK chargers are built to last. They stand up to tough shop and track use thanks to components designed for extreme durability, vibration resistance, and water/dust resistance (IP65 rating).

With features like auto voltage detection, Supernight modes for very slow charging, and super compact portable designs, CTEK chargers offer many convenience and performance features missing from budget competitors. You get premium capabilities even with basic CTEK models.

Finding the Best Deals on Top-Rated CTEK Chargers

Finding the Best Deals on Top-Rated CTEK Chargers

CTEK makes some of the best smart battery chargers on the market. But their innovative features and proven performance come at a cost. CTEK chargers are generally more expensive than basic budget-priced models.

Luckily, there are ways to find CTEK chargers at discounted pricing so you can get advanced charging features without paying premium prices. Here are some tips for finding the best deals on top-rated CTEK chargers to save money without sacrificing quality and performance.

Shop End of Model Year Sales

Like cars, new models of CTEK chargers come out on an annual basis. Retailers will often discount older models nearing the end of their product cycle when new versions come out. This is often timed around peak winter holiday shopping periods.

Search for prior year CTEK models around late fall/early winter. Retailers are motivated to sell remaining inventory before the new year. You can snag a high-end charger for 30% or more off in some cases.

Take Advantage of Promotions

Sign up for retailer newsletters and keep an eye out for periodic promotional discounts. CTEK chargers will sometimes be included in sitewide sales, especially around major holidays like Memorial Day, July 4th, and Labor Day.

Promos tied to large events are a great chance to save an extra 10-20% on the charger you want. Stacking these with coupons or cash back makes the deals even sweeter.

Buy Refurbished and Used

Consider purchasing manufacturer-refurbished or used CTEK chargers to maximize savings. Refurb units directly from CTEK come with a warranty and go through stringent quality control and testing.

Used chargers such as customer returns may have some cosmetic blemishes but work perfectly. websites like eBay provide buying protections as well. Just be sure to inspect condition closely before purchasing used.

Price Match Guarantees

If you find a lower advertised price on your desired CTEK charger, many retailers will match the pricing under price match policies. This allows you to shop around for the best deal then get that pricing matched by the retailer of your choice.

To qualify, the other retailer must be authorized, have the item in stock, and policies must match (i.e. new, refurbished, open-box)

Stack Discounts and Coupons

Combining multiple discounts and coupons on a single CTEK purchase can drive the savings up even more. For example, use a 20% off coupon code with a buy one get one half off promotion. Retailers also often have additional discounts for email sign up, military, first responders, and students.

You can layer on instant rebates, cash back bonuses, and free shipping offers for maximum value. Just make sure discounts don’t conflict in terms and conditions.

Buy Bundles

Some of the best CTEK charger deals come from bundling the charger with other products like battery maintainers, desulfators, or electronic battery testers. The bundle pricing is lower than buying each piece separately.

For example, the CTEK MXS 5.0 charger bundled with their battery tester saves you around $30-40 instead of purchasing them individually. Keep your eye out for value bundles relevant to your needs.

Shop Around

Prices can vary among different authorized CTEK retailers, so take time to shop around. Compare prices on CTEK.com, Amazon, Walmart, AutoZone, PepBoys, eBay, and anywhere else the charger is sold.

Factor in any additional discounts, coupon codes, rebates, or incentives when comparing pricing to find the best deal. Even a few dollars saved here and there adds up.

Buy Online for Lower Prices

Online retailers tend to offer lower pricing than brick and mortar stores simply due to lower overhead. If buying locally, check online prices and see if the local store will price match their online competition.

Just be aware of potential shipping charges that can eat into savings when buying online. Factor those costs in before pulling the trigger.
