FAQs
High-Quality 12 Volt Battery Chargers
A high quality 12-volt charger is one that is microprocessor contolled, and will maintain a battery after it is fully charged, without overcharging the battery. Chargers like Battery Tender, Battery Saver, CTEK, and Pulse Tech offer smart chargers that can be left on a battery for long periods of time. These type of chargers have built-in safety features that will stop the charger from charging if it has been in the charge mode too long. At BatteryStuff we pride ourselves on carrying quality chargers that solve problems, not cause them!
Why Should I Use a 12v Battery Charger?
A 12-volt battery trickle charger is the most valuable tool in saving the life of your battery and is responsible for keeping it charged and ready to go when you need it. Using the proper charger for your application is crucial to your battery. Some manufacturers of gel cell, solar and AGM batteries will not honor warranties if the proper 12v battery maintainer isn’t used.
Take the guesswork out of battery charging with a 12-volt charger from BatteryStuff. Order today.
