NOCO, Schumacher & Stanley Chargers — From Trickle Maintainers to Multi Bank Systems

Our selection includes NOCO Genius smart chargers from 1-amp maintainers to 50-amp fast chargers, Schumacher automatic battery chargers with engine start assist, and Stanley professional-grade units for shop and fleet use. For trucks and boats stored through winter, our battery maintainers and trickle chargers deliver a slow, consistent charge that prevents sulfation and dead cells without overcharging. Multi bank battery chargers from NOCO handle 2, 3, and 4 batteries simultaneously — ideal for dual-battery diesel trucks, boats with trolling motors, and multi-vehicle garages.

We also carry solar battery chargers from NOCO and Schumacher for off-grid trickle charging on parked trucks, RVs, and trailers, plus Level 1 and Level 2 portable EV chargers for home and travel use. For lithium jump starters and booster cables, browse our full Electronics collection. Pair your charger with a remote start system from our Remote Starters collection to keep your truck warm and battery-ready through winter. For 12V power inverters, adapters, and accessories, check out our 12V Accessories collection.

If you are building out a work truck or fleet vehicle, browse Commercial for tool boxes, headache racks, and cargo management. For towing setups that need trailer battery charging, check out our Towing collection for breakaway kits, trailer wiring, and brake controllers.

Frequently Asked Questions

What is the difference between a trickle charger and a battery maintainer?

A trickle charger delivers a continuous low-amp charge to a battery regardless of its charge level, which can lead to overcharging if left connected too long. A battery maintainer monitors the battery's voltage and automatically adjusts or stops charging once full capacity is reached, then resumes when voltage drops. For long-term storage on trucks, boats, and RVs, a maintainer is the safer choice because it prevents overcharging and sulfation damage.

What is the best battery charger for trucks in cold Canadian winters?

NOCO Genius smart chargers are built with thermal compensation that adjusts charging output based on ambient temperature, making them ideal for Canadian winters. For diesel trucks with larger batteries, a 10-amp or 25-amp smart charger provides enough output to recover deeply discharged batteries in freezing conditions. Pairing a smart charger with an OBD-II memory saver cable also prevents ECU and radio resets during battery removal in cold weather.

Is it safe to leave a battery maintainer connected to your truck all winter?

A quality battery maintainer from NOCO or Schumacher is designed to stay connected for months without damaging the battery. These units monitor voltage continuously and only deliver charge when the battery drops below a set threshold. For trucks stored in unheated garages or outdoors through Canadian winters, a maintainer keeps the battery at full capacity and prevents the freeze damage that occurs when a discharged battery's electrolyte solution drops below freezing.

What is the difference between an onboard and portable battery charger?

An onboard battery charger is permanently mounted inside the vehicle, boat, or trailer and wired directly to one or more batteries — you simply plug in the AC cord when parked. A portable battery charger is a standalone unit you connect with clamps or ring terminals as needed, then disconnect and store. Onboard chargers are ideal for dual-battery diesel trucks and boats where regular charging is part of the routine, while portable chargers offer flexibility across multiple vehicles.

Can a solar charger keep a truck battery charged during storage?

A solar battery charger can maintain a truck battery's charge during storage by providing a slow trickle of power that offsets the natural self-discharge rate. Solar panels rated between 2W and 10W are sufficient for maintaining a fully charged truck battery over weeks or months of storage. However, solar chargers are not powerful enough to recover a deeply discharged or dead battery — for that, a plug-in smart charger with higher amperage is needed.

What amp battery charger do I need for a truck battery?

For standard truck batteries (Group 34, 35, or 65), a 5-amp to 10-amp smart charger handles overnight charging and regular maintenance. For diesel trucks with larger Group 31 or dual-battery setups, a 15-amp to 25-amp charger delivers faster recovery times. For shop or fleet use where you need to charge multiple trucks or start engines on deeply discharged batteries, a 40-amp to 80-amp charger with engine start assist from Schumacher or Stanley is the right choice.
