Our Clients Thought

As an avid boater, I rely on my Cen Tech marine battery charger to keep my trolling motor powered up for each fishing trip. I bought the 15 amp model last season and have been extremely impressed with its performance and durability. It charges my large deep cycle battery from dead to full in just a few hours. The sturdy waterproof case is perfect for the damp marine environment. I really like the automatic multi-stage charging that prevents overcharging. My battery has never been in better condition. After a full day on the lake, I just plug it in and it's ready for the next trip. For a budget charger, this thing delivers premium results. I'm confident it will keep me on the water for years to come. Couldn't ask for a better marine charger.

I manage an auto repair shop and we use Cen Tech chargers for all customer vehicles. The shop owns 3 of their 10/40 amp automatic chargers which see near constant daily use on dead car batteries. Despite the heavy usage, these chargers just keep going strong after 5+ years of service. The reverse polarity warning has saved my technicians multiple times from accidentally hooking up backwards. The quick engine start function has gotten many customers back on the road when a jump start was needed in addition to charging. And I really appreciate the portable handle which allows us to easily move the chargers around the shop. For the price, you won't find more convenient and durable chargers. Cen Tech has become our shop's go-to brand for chargers due to their reliability.

As an avid motorcyclist, I frequently use my Cen Tech motorcycle charger after letting my bike sit too long in storage. I love that it plugs directly into the OptiMate port on my BMW without needing to access the battery itself. The convenient harness adapter also lets me charge other motorcycles. The automatic float mode is great for maintaining the charge over long periods of storage. One time, I accidentally left it hooked up too long after a full charge. But thankfully, the charger switched to a safe float voltage on its own to avoid overcharging. For those of us who tend to neglect our batteries after riding season ends, this charger has been a lifesaver to keep my bike ready to go come springtime. It takes the guesswork out of charging a motorcycle battery. Very pleased with this product.

As a busy mom of 3 kids, I love that Cen Tech's battery maintainers make it so easy to keep my minivan battery charged. With all the shuttling my kids to school and activities, I was constantly coming out to a dead battery from leaving the interior lights on overnight. But ever since getting one of their automatic float chargers, the battery stays fully charged no matter how much I drain it. I just keep the maintainer plugged in to the cigarette outlet, and it juices up the battery as needed without me having to think about it. The peace of mind of knowing I'll never get stranded with a dead battery is well worth the small price. And the charger is so compact, I was able to tuck it out of sight behind the glove compartment. For any busy parent whose car battery is constantly getting drained, I highly recommend picking up one of these maintainer chargers. It's cheap insurance against getting stuck with a dead battery!

As the facilities manager for a large corporate office complex, I manage a fleet of electric golf carts for cruising the extensive grounds. After dealing with short battery life and constant recharging issues, I switched to using Cen Tech's 24 volt 15 amp golf cart chargers. Their 3-stage charging does an amazing job optimizing our large 220ah batteries compared to the generic chargers we were using. Battery life has improved remarkably and charge times are much faster. The durable powder coated steel case stands up to the intense heat of the Arizona sun and still works like new. For the heavyfrequent charging our carts require, these chargers have really improved reliability and reduced maintenance costs. The cart staff tell me how much easier the quick-connect harness makes daily charging. For industrial electric vehicle fleets, I don't think you'll find a better value charger with these smart charging features. Outstanding product that has really made a difference for our facilities operations.

FAQs

Charge times depend on the battery capacity and charger amperage. For example, their 750 peak amp car starter can charge a dead 50Ah battery in 1-2 hours. Lower amperage chargers may take 6-12 hours for a full charge. Check the product details for charge time estimates.

Our chargers are compatible with all common battery types including lead-acid, AGM, gel cell, lithium, and more. Refer to the product details for the specific battery voltages supported.

Our automatic chargers switch to a float or maintenance mode once the battery is fully charged. The indicator light will change from red to green. Charging then stops to prevent overcharging.

Yes, we make chargers designed specifically for these applications. Select a charger with the proper output voltage and charging profile to work with your battery system.

Our chargers include protections like reverse polarity detection, over-voltage shutoff, overheat protection, short circuit prevention, and more. These features prevent battery and charger damage.

The clicks are the internal relay activating the different charging stages. This is normal operation. Contact us if clicks persist after the battery is fully charged.

Our automatic maintainers switch to a safe float mode and may be left connected indefinitely without risk of overcharging.

Avoid deep discharges and recharge as soon as possible. Our multi-stage chargers optimize recharges to extend battery life. Proper maintenance is key.

Our chargers are designed solely as battery chargers and are not intended for use as general power supplies. Consult our product support team for questions.

Periodic blinking is normal and indicates the charger is in a pulsing/analyzing mode to optimize the charging process. As long as the battery is charging, blinking is no cause for concern.
