Charge a 6V Battery with 12V PulseTech Chargers

PulseTech XC100-P

Over in the online store today, a customer posted a question about PulseTech products. If you read our last post about PulseTech and battery care, you already know how beneficial PulseTech products are for extending the life of your lead-acid batteries. But what if you want to enjoy the benefits of pulse charging for a 6V battery? Browsing through our selection of PulseTech products turns up a bunch of 12V chargers, and on-board conditioners for 12, 24, 36, and 48V batteries, but no 6V chargers.

Visitor Arrnold asked if we carried 6V PulseTech products, and the answer is no. PulseTech doesn’t make 6V chargers. It seems unfair, but there’s a manufacturer-sanctioned workaround: If you connect two 6V batteries in series, your charger sees them as a 12V battery, so you can use any PulseTech product you want! According to PulseTech’s FAQ:

Although all of our products are designed for 12-volt systems, application of Pulse Technology on 6-volt batteries can be achieved through series connection of 6 volt batteries creating a 12-, 24-, 36- or 48-volt system. Product use is dependent on final overall system voltage.

OK, so they said it can be done, but it’s not the most user-friendly explanation if you don’t already know how to connect batteries in series. So, we’ve created a simple diagram showing how to connect either two or four 6V batteries together, to create a 12V battery bank. But first, a couple basic things to remember:


What & Why: Battery Maintenance

Anyone who has purchased a lead-acid battery recently, either for a car or a renewable energy system, knows battery prices have gone through the roof in the last couple of years. Battery maintenance used to be of interest mostly to people with fleets of vehicles, or large power storage systems, but now maximizing battery life has become a major money-saver for almost everyone.

Basic battery maintenance includes making sure your battery electrolyte is topped off (unless the battery is fully sealed, like most automotive batteries are these days), and making sure the battery stays charged. But even then, especially if you live in an extreme climate, you’ll still notice your batteries wearing down over time. Using a pulse charger or pulse conditioner takes your battery maintenance routine to the next level.

Battery pulse conditioners can triple the life of lead-acid batteries, as well as keep them performing like new. This means your power storage system is always operating at peak capacity, and your vehicle’s engine turns over and charges more easily (minimizing wear and tear on your starter and alternator).
