question about Everstart Marine Batteries

[SkunkWerX]

I agree with bx23barry as to the use of deep cycle batteries. Starting batteries and deep cycling batteries are designed for different functions. It's like comparing a sprinter (starting battery) to a marathon runner (deep cycling battery). Jay

Folks, there are two types of Marine batteries:

Deep Cycle or "cabin" batteries, just like a deep cycle RV battery and there are Marine Deep Cycle/Starting batteries. It should say "Deep Cycle/Starting".

The Marine Deep Cycle/Starting batteries are made with a deeer cycle than a car battery, since boats can sit for weeks or months without being cranked, yet, they can also be slow drained for radios and lights while you are not running (like when fishing or running a trolling motor) and still have the reserve to start the boat engine to get you home.

My best description is that they are like a dual purpose battery.
It's they way they are made, internally, that gives them the best of both worlds.

I have used these "Marine DeepCycle/Starting" batteries in my old Ford 1210 tractor with very good performance and longevity. And yes, helps in the cold too! Amongst farmers along the shoreline, using Deep Cycle/Starting batteries are common knowledge, and are well stocked in our auto parts stores year round, due to the demand from boaters.

You still need to match the CAs and CCAs , as normal.

SkunkWerx:

Thank you for the clarification. I did not know that they now made Marine DeepCycle/Starting combination batteries. (I have no batteries larger than a 9 Volt in my little sailboat and a 4HP yank start outboard when the winds fail ). Jay

I've been using a marine "deep cycle" battery in my JD 38hp for 6 months now, no problems. I bought new ones for the boat that were on sale at Cabelas Bargain Cave for $25. My only concern was whether the charging system would care about the back-draw resistance it uses to know when to cut down the field current. Does not seem to care.

The deep cycle means that a trolling motor will draw the battery power down until its almost completely dead, unlike most vehicle batteries which always hover around 12 volts because of continuous charging. My bass boat only sees a charger when the batteries are dead. They do not share charging from the outboard's charging system. When dead, they don'r care that they will be born again.

Anyways, a deep cycle is also useful for tractors where the DC generator or AC alternator is dead and you need to run. You can get a lot of starts out of a deep cycle without ruining it. 4 -5 DOAs on a regular batter pretty much swells up the plates.

The bigger, higher cappacity battery will heat up the glow plugs more quickly (or get them more hot if you always use the same 20 seconds of time), so it actually can run better at initial start.
