NOCO Genius G750 Battery Charger Video Guide

Hi my name is Richard Price and I am with High-Tech Battery Solutions. Today we are going to be talking about the NOCO G750 battery charger. The NOCO G750 is NOCO’s entry level battery charger / maintainer, it will do both 6 and 12 volt batteries of different chemistries including flooded batteries found in cars, AGM batteries as well as GEL batteries.

Straight out of the box your going to get the G750 which is a direct wall mount charger and your going to get a pair of plastic battery clamps as well as a pair of permanent mount eyelet terminals. Now both of these connectors are going to be whats called a quick disconnect. You can permanently mount either of these options, pull your car into the garage and hook it up to the charger.

NOCO 5 Stage Charging Cycle

The NOCO G750 is going to feature a 5 step charging cycle. We are going to dive into a little bit about what exactly each step means in terms of what its going to do for the battery itself just so you have a general understanding of why this charger is going to be a little bit superior when compared to the other battery tenders that are out there today.

Step 1: Diagnostics

The first step is called the diagnostic step. This is going to check the battery voltage to make sure the battery connections are good and the battery is in stable condition before beginning the actual charging process itself.

Step 2: Soft Start

The second step is called a soft start - prior to the actual full charging process. The second step is going to begin the bulk charging process with a gentle or soft charge, so in other words its not going to hit it hard and quick, its going to put in a small charge to make sure that every internally is going to be okay with the battery.

Step 3: Bulk

The third step is called the bulk charge phase. In this step, its going to continue the bulk charging process to return about 90% of battery capacity. So its not going to charge it all the way up in this particular phase its going to get it to about 90 - 95% charged and then its going to kick over into the fourth phase.

Step 4: Absorption

The fourth phase is called the absorption phase, which will begin charging the battery to the 100% mark. The battery charger will deliver small amounts of current to deliver a safe and efficient charge and limit battery gassing - which is extremely important in both GEL and AGM batteries.

Step 5: Maintenance

The fifth step, or the maintenance step, will monitor the battery voltage continuously to determine if a maintenance charge should be initiated. If the battery falls below a certain voltage either a 6 or 12 volt battery it will kick on to whats called a maintenance mode or pulse charge that will bring it back up to a healthy and sustainable voltage level and will cut the charger off until its needed once again.

Note: For a bit more detailed information on the 5 step charge cycle used by the G750, you should check out Introducing The NOCO G750 Battery Charger. This article focuses almost entirely on the charging algorithm.
