5.Some sugguestions when using the battery charger

Step 1: Choosing a Charger Based on Battery Type

Whether your battery is maintenance free, wet cell (flooded), AGM (absorbed glass mat), gel cell or VRLA (valve-regulated lead acid), one charger should work for all types except for gel cell. However, some of our gel cell chargers will work well with the other battery types.

Step 2: Determining Battery Size

We don’t mean physical size, but how many amp hours your battery stores. For example, a typical full-size auto battery is about 50 amp hours, so you would choose a 10 amp charger that would take about 6 hours to recharge it if the battery were completely dead. Another instance would be a marine deep cycle battery rated at 100 amp hours. It would take a 10 amp charger about 11 hours to recharge a dead battery to near 100% full charge. To calculate your total charge time, a good rule of thumb is to take the amp hour rating of the battery and divide by the charger rating (amps) and then add about 10% for the extra time to totally top off the battery.

Some folks wanting quick recharge should look for a charger with more amps. If you’re not in a hurry, you can select a smaller charger. The most important thing is to make sure you have enough charger power to do the job you require in the time you allocate.

Step 3: Choosing a Battery Charger Based on Desired Outcome


Some folks require a charger to keep their motorcycle, classic car, or aircraft battery charged during the offseason. In these cases, a simple low current charger will work fine. Others require a fast and powerful charger to quickly restore a trolling motor battery or a wheelchair battery set. Other types of chargers and the reasons you might need them:

MULTI VOLTAGE Input chargers for use when visiting a foreign country

Waterproof chargers for those times when you’re out in the elements

Chargers that double as power supplies for RV use

Multi-bank chargers for charging multiple batteries simultaneously

Hopefully, we’ve helped you figure out which is the best charger for your application.
