How do I know what battery charger to buy?

As a rule of thumb, your charger should be 10% minimum of your battery’s Ah rating. This means a 100Ah battery would need a 10 Amp charger minimum. You can increase the battery charge amp if you need the battery to be charged at a faster timeframe. Choosing the right battery for your device is only half the story.

Are battery chargers interchangeable?

The answer to this question is pretty much the same as that about cordless drill batteries – i.e., some drill chargers are interchangeable whereas others are not. It is safe to use a low – voltage charger for a battery marked at a higher voltage rating (e.g. using an 18-volt charger with a 20-volt battery).

Are all battery charger the same?

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.

How can you charge a battery without a charger?

When you are in an urgent need to charge a lithium-ion battery (6600-37) without a charger, the easiest and hassle-free way is to charge it with a USB port. To charge a li-ion battery (6600-37) using a USB port is simple & tricky.

Are there different types of battery chargers?

There are two different types of battery chargers on the market today – Timer Controlled chargers and Smart chargers (also called Intelligent chargers), each for a different budget, (Timer Controlled are less expensive), but more importantly, using two different technologies.

How do you know when battery charger is done?

As they charge the battery, the needle will move down the scale to 8-amps, 6-amps, and so on. Until the needle reaches 0-amps to display the battery has completed charging. And when the needle moves from the 10-amps to the 0-amps/100 percent position, it moves through the green triangle.

Why are my coach batteries not being charged?

IF you have good voltage from the alternator something downstream is not allowing the batteries to charge, follow all the wires off the alternator. Most RV’S have a battery isolator or solenoid that will allow the coach and house batteries to charge while driving.

What kind of battery charger does coach RV use?

I have checked the 120VAC to 12VDC inverter that I assume is supposed to charge the coach batteries. It produces 13.5 VDC (with no load) and powers all of the 12V components in the RV. The RV uses an Intellitec battery disconnect system. Inside the door are two switches to disconnect the chassis and coach batteries (see photo below).

Where did the batteries for the coach come from?

Of course, it was too late to save our original coach batteries, so on our way south to the Annual Rally just before Labor Day 2005, we stopped in at the Interstate Battery dealer in Portland and “ponyed up” for four new house batteries.

What should the battery voltage be in a coach?

Start the coach and run it at around 1500 Rpm’s and the battery voltage should rise over 14 volts and then should drop down as Rpm’s are decreased, inspect the alternator belt make sure it is snug and not slipping.

Why is my coach battery not charging from the engine?

When I check the battery at the charger it shows the same voltage as the battery. When I do this same test while plugged in or running the generator the voltage is higher indicating it is charging. I have a used 1999 Winnebago Chalet. I installed a new progressive power dynamics replacement charger before I left.

Where do I Disconnect the coach battery in a RV?

The RV uses an Intellitec battery disconnect system. Inside the door are two switches to disconnect the chassis and coach batteries (see photo below). Also below photos of the Intellic disconnect relays inside the power distribution box that’s in the engine compartment.
