Batteries room a critical element on a boat, however they’re frequently neglected — right up until the minute they protect against working. Suddenly the lighting, bilge pump, electronics and engine starting system i will not ~ work. You stuck, hopefully not in the middle of the bay. What perform you do now?

The key to preventing battery failure is rewildtv.come look after ~ them. Below are 5 of the most rewildtv.common ways that marine batteries meet their finish — and how to protect against them.

You are watching: How must a storage battery be positioned on a boat?

1) usage the wrong sort of battery

The surest method to easily kill a marine battery is to usage the not correct kind. Marine batteries are made in a range of types and for different applications, so picking the ideal one is vital.

Due rewildtv.come their reduced cost, the most rewildtv.common form of maritime batteries are the flooded lead acid type (e.g. Wet cell batteries). There are additionally gel batteries, Absorbent Glass Mat (AGM) batteries and also spiral-wound battery derivatives; and also lithium-ion maritime batteries, return they have tendency to be an ext expensive.

Marine batteries space made to meet two applications. Beginning batteries, also known together cranking batteries, administer a huge jolt the amperes. Together the names implies, castle are typically used to begin a naval engine and are developed to recharge quickly.

Deep cycle batteries are designed to administer fewer amperes however are plan to run for longer. They run the miscellaneous electronics contents on a boat and also are expected to recharge much more slowly. ‘Pure’ deep cycle batteries aren’t designed rewildtv.come be totally discharged. Instead, castle have an ideal operating range (typically about 60 every cent) and also shouldn’t it is in discharged below this level.

Dual-purpose batteries space also very rewildtv.common. Periodically referred rewildtv.come as just marine batteries, they administer a balance between starting and deep bike use.

A cranking battery repeatedly used for deep cycling deserve to degrade in a issue of weeks, and vice versa, so select the ideal one.

2) Overcharge and undercharge

Batteries should be properly kept in order to last. Necessary to maritime battery maintain is suitable charging so always use a charger the meets the manufacturer’s rerewildtv.commendations.

Regularly under-charging a battery erodes the performance and also reduces that life due to a phenomenon referred to as sulfation. This occurs as soon as lead sulfate crystals form on the an unfavorable plates, impeding performance and also reducing the battery’s ability to charge. Eventually this can render that unusable.

Excessive or incorrect overcharging deserve to be equally damaging, specifically with AGM and gel batteries. Law so can ‘cook’ a battery so it is vital to follow the manufacturer’s charging rerewildtv.commendations.

Thankfully, countless readily obtainable tools and also accessories are easily accessible to save your battery in running order. For example, charging and maintaining a battery over lengthy idle periods (like winter) using a multistage charger choose SmartCharge will expand its life.


3) Don’t maintain your battery

Marine battery maintenance method more than continuous charging. Neglecting other creates of maintenance can likewise lead to deterioration.

Water loss, due to evaporation from heat and other chemical reactions, is usual in wet cell batteries. It deserve to rapidly shorten a wet cell battery’s life if left unchecked, for this reason ensure the water level stays topped up (but no to overflowing). Just use distilled water, together impurities in insanity water will accumulate inside the battery. Keep in mind that deep bicycle batteries often tend to lose water much faster than starters.

External contents should likewise be inspected. Check that the lead articles don’t show signs the rewildtv.coming turn off (they can be weekend if a terminal to be forcefully connected). A gentle dose of grease, lanolin or Vaseline deserve to stave turn off corrosion on exposed steel terminals. When a year, clean out the battery box, check for signs of leaks and corrosion, check the vent is clear, and also inspect the tie-downs.

4) place the battery in the dorn spot

Marine batteries differ to vehicle batteries in the they room meant to operate in an setting that will be subjected to solid vibrations.

Even so, a poorly mounted setup deserve to suffer from excessive vibrations, which in turn loosens the inner workings, eventually weakening the battery.

The battery crate (especially on smaller sized boats) should be situated where it i will not ~ be adversely influenced by wave pounding and also engine vibrations. That should likewise be positioned in a place where that won’t acquire flooded through seawater. Wet contact batteries should additionally be situated in a location with adequate ventilation.

5) buy the cheapest possible marine battery

As through so numerous things in life, you gain what friend pay for with boat batteries. As mentioned, maritime batteries should fulfil several features so the temptation may be to buy an automotive battery. While no contrary to any kind of regulations, utilizing a battery that is less likely to resist vibrations or i beg your pardon can’t handle steep discharge cycles puts you at risk.

Purchasing a second-hand battery is normally inadvisable. Friend don’t know its background and it’s probably not spanned by the manufacturer’s warranty.
