What Are The Differences Between A Starting And Lead Acid Replacement Battery?

Starting batteries are generally designed to start some form of an internal combustion engine (car, truck, boat, etc). In a starting battery, you will find more lead plates, thinner and often made of a lead “sponge” similar looking to a foam sponge. This sort of arrangement means that the plates have much more surface area in the solution than a Deep Cycle battery and allow them to draw larger currents much quicker than a Deep Cycle battery.

Lead acid replacement battery, on the other hand, have much thicker plates and, they are solid, not sponge. These thicker plates have less surface area and thus less of the instant power that a starting battery needs. They are designed to be discharged down to 20% of their maximum charge repetitively. The thicker lead plates allow for this as they are much sturdier than their sponge counterparts.

Cold Cranking Amps (CCA) is an indicator of the amount of current a battery can deliver for 30 seconds at zero degrees Fahrenheit without dropping below a specified cutoff voltage (normally 10.5 volts). The cranking amps a battery can produce changes with temperature. The warmer it is the more Cranking Amps a battery will produce.

Types Of Lead Acid Replacement Battery

Flooded deep-cycle batteries: These are the most common type. They are relatively inexpensive and easy to find. However, they require regular maintenance, such as adding distilled water to the electrolyte.

Sealed deep-cycle batteries: These batteries are also known as maintenance-free batteries. They do not require the addition of distilled water, making them easier to maintain. However, they are more expensive than flooded deep-cycle batteries.

Absorbed Glass Mat (AGM) batteries: AGM batteries have a glass mat that absorbs the electrolyte. This makes the electrolyte more evenly distributed throughout the battery, which helps to improve performance and lifespan.

Gel batteries: Gel batteries add a gelling agent to the electrolyte. This makes the electrolyte thicker and more viscous, which helps to prevent the battery from leaking.

Lithium-ion batteries: Lithium-ion batteries are a newer type of lead acid replacement battery that offers several advantages over traditional lead-acid batteries. They are lighter, have a longer lifespan, and can be discharged more deeply without damage. However, they are also more expensive than lead-acid batteries.

The Components Of Lead Acid Replacement Battery

Lead plates

The lead plates are the active part of the battery. They react with the electrolyte to produce electricity.

Electrolyte

The electrolyte is a mixture of sulfuric acid and water. It conducts electricity and helps to carry the chemical reaction between the lead plates.

Case

The case protects the battery from damage and holds the other components in place.

Lead Acid Replacement Battery Precautions

Safety first
Before you troubleshoot a battery, be familiar with the potential risks of handling any battery. This includes wearing personal protection equipment (goggles, gloves, etc.); removing metallic objects such as jewelry, and working in an open, well-ventilated area. Before your inspection, ensure you fully charge the battery to get an accurate reading of the lead acid replacement battery condition. Or, if you can't charge the battery, let it sit for one hour after use.

Check for damage
You can often detect problems with your battery simply by looking for the following:

Broken or loose terminals: If any terminals or connections are loose, damaged, or corroded, they can result in dangerous short circuits.
Leaking or a damaged battery case: A leak can indicate a damaged battery case in flooded batteries. While the damage wouldn't prevent the battery from working, operating a battery with a damaged case is dangerous. (Leakage will not occur with an AGM battery, even with a damaged case.)
Dirt and grime: Check the top of the battery and terminals for dirt and grime during your inspection. This corrosive buildup could cause the lead acid replacement battery to self-discharge when not in use. Make it a point to remove any corrosion from your battery terminals or connecting cables to ensure the battery is working and charging efficiently.

Lead Acid Replacement Battery Inspection Process

Fluid inspection
Using a hydrometer to measure the specific gravity of the acid within the battery fluid.
Following lead acid replacement battery charging service, the hydrometer reading of all cells should be at least 1.225 -- and show less than 50 point difference between the high and low readings.
A fully charged and healthy battery will show clear fluid without discoloration and a hydrometer reading 1.265.

Voltage inspection
Battery voltage after charge effectively indicates lead acid replacement battery health.
Batteries with less than 100% voltage should be recharged before use. A 12-volt battery will read 12.6 volts or higher after charge; a 6-volt battery will read 6.4 volts or higher after charge.
Make sure the battery terminals are free of corrosion before testing.

Load test inspection
Batteries must be at 100% voltage before applying a load test.
When load testing, remove all lead acid replacement battery cables from their terminals.
Using a load tester, apply a 15-second load equivalent to 50% of the battery's CCA rating.
Refer to the load testers' minimum passing voltage to determine the battery condition. If the test voltage is below the minimum, replace the battery.
If your battery still performs poorly, you’ll find helpful troubleshooting ideas in our seasonal battery brochure for deep cycle and AGM batteries.

Check now — Save big later
Just like with a car, don’t let minor problems with your battery go unnoticed; small issues can quickly lead to much bigger problems (and more expensive) problems later... and end up damaging your lead acid replacement battery beyond repair. Get the most life out of your deep cycle battery by checking for small things and performing tests regularly.

Asked Questions

Q: How do I charge these batteries?

A: All of these batteries require a lead acid replacement battery charger of some type (like a converter/charger, inverter/charger, solar charge controller, etc.) that is set to the correct charging profile for that type and model of battery. You cannot assume that just because a battery charger has an “AGM” mode that the charger will adequately charge your AGM battery, it must have the voltage setpoints (if adjustable) set to the correct voltages for each type of charging cycle. Check the specifications for your battery to find the manufacturer’s recommended voltages.

Q: Where should the RV battery bank be located?

A: We recommend you locate your RV house battery bank in a sealed battery box in the interior of your camper van, preferably vented to the outside (lithium batteries do not require a sealed or vented box). If you keep your batteries around average room temperature, not cold or hot, they will serve you for a long time. Having an interior battery bank will also minimize the lengths of your wiring runs, which will keep voltage drop low and save you money on materials.

Q: How can I connect batteries together?

A: Batteries can be connected in series or parallel configuration, depending on whether you need to a certain voltage for the lead acid replacement battery bank. Most RV battery banks are 12-volt banks, so they have 2 6-volt batteries wired in series, or 2 12-volt batteries wired in parallel. Many 6-volt deep-cycle lead-acid batteries have thicker plates than 12-volt deep-cycle batteries, so they can last longer. Batteries should be physically connected with very thick battery cables sized accordingly, often with 2/0 or 4/0 battery cables.

Q: Can I connect different batteries together?

A: No – Any batteries connected together should be of the same type, model and capacity, and the same age. They should also be in one location, and with identically-sized wiring (both in wiring gauge and length) to the charging source. An exception to this is that your camper van engine starter battery can be connected to the house lead acid replacement battery bank with a battery isolator, battery combiner or charging relay, so that the house bank can be charged via the alternator or the engine battery charged via solar.

Q: How often should lead acid replacement battery be replaced?

A: Between years three and five, the lead acid replacement battery is considered to be in a phase of critical deterioration. When a Lead-acid battery reaches 80% capacity, it is considered at the end of life (EOL). Institute of Electrical and Electronics Engineers (IEEE) standards recommend replacing a battery when its capacity is below 80%.

Q: Can I replace a 12v 7Ah battery with a 12v 10Ah battery?

A: So going from a 7Ah to a 10Ah will be fine as long as the larger battery fits as for the most part, a larger capacity lead acid replacement battery will be physically larger. It is usually indirectly related to the amount of current the battery can safely supply but this is not a hard-and-fast rule.

Q: Is it OK to replace a lead acid battery with AGM?

A: Even though there's a myth stating you can't install an lead acid replacement battery into a flooded battery application, that is not true. You can — and here are some tips on changing and upgrading to an AGM battery to make your life a little easier.

Q: Do you need to charge a new lead acid battery before use?

A: A battery must be charged to 100% before putting it into service. To find recommended charging current requirements in amps for a specific battery, divide the battery ampere-hour capacity rating by 10. For example, a 14 AH lead acid replacement battery should be charged at 1.4 amps (14 AH ÷ 10 = 1.4 amps).

Q: What kills a lead acid battery?

A: Some owners discharge their batteries too deeply, permanently altering their chemistry and function. Others overcharge their batteries or charge them too quickly, which can do equal amounts of damage. Operating in extremely hot or cold temperatures risks harming the health of your battery as well.

Q: How many hours will a 12V 7Ah battery last?

A: Assuming a constant discharge rate, a 12V 7Ah battery can theoretically provide 1 ampere of current for 7 hours, 2 amperes for 3.5 hours, 3 amperes for 2.3 hours, and so on.

Q: Is 12Ah better than 7Ah?

A: This is 12 volts and with it being 12ah will last much longer than the one you have that is 7ah. It will need to charge longer, depending on the charger you have. Check the amp output on your charger as this one may take almost double the time to charge but will last much longer.

Q: What kills AGM batteries?

A: If the charge level of a fully charged lead acid replacement battery is less than 20% of a fully charged voltage level, the battery could have been damaged by sulfation, overcharging, or undercharging.

Q: What will ruin an lead acid replacement battery?

A: Regular battery charging can break lead acid replacement battery. Regular batteries need 15-17 volts to get the same amps. However, voltage greater than 15 volts can overheat an AGM and generate enough pressure to pop its safety valve.

Q: Can you trickle charge a sealed lead acid battery?

A: Yes. A correctly designed full rate charger will also trickle charge a battery. A low current trickle charger will also charge a discharged battery, but it will take a very long time.

Q: Can you mix old and new lead acid batteries?

A: Lead-acid batteries play a very important role in our everyday applications. As we all know, batteries should be replaced when they are old and never mixed with old and new. Otherwise, not only will they not save power, but they will waste it.

Q: What is the life expectancy of a lead acid battery?

A: Sealed lead acid batteries can have a design life of anywhere from 3 – 5 years all the way up to 12+ years depending on the manufacturing process of the lead acid replacement battery. There are many factors that affect the service life of the battery including temperature, for more information please view our technical manual.

Q: How do I know if my lead acid battery is bad?

A: Low voltage: A lead-acid battery that is not holding a charge or is not providing enough power will typically have a low voltage reading when measured with a multimeter. Swelling or leakage: If a lead-acid battery is swelling or leaking, it is likely that it is no longer able to hold a charge and should be replaced.

Q: How long can a lead acid battery sit dead?

A: Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid lead acid replacement battery after a (partial) discharge to keep them from quickly deteriorating.

Q: When should a battery be replaced without testing?

A: General wisdom says you should replace your car battery about every three years, but you could end up needing a replacement sooner. Factors like your climate and driving habits can affect your battery's lifespan and leave you needing a new one before the three-year mark.

Q: How long does a new lead acid battery take to charge?

A: Lead acid batteries generally have a run time of between 5 and 6 hours. When they need to be recharged, that process takes approximately 8 hours. Although the charging process completes in 8 hours, another 8 hours of cooling down time is typically required.
