The Amp Hour or Ampere hour (abbreviated Ah) rating tells you how much amperage is available when discharged evenly over a period of an hour (60 minutes). As an example, a 200Ah (20 hr rate) battery can sustain a 10-Amp draw for 20 hours before reaching 100%DOD.

Since the container is not sealed, great care has to be taken to ensure that the electrolyte does not come into contact with you (burns!) or seawater (chlorine gas!). As Gel cells are sealed and cannot be re-filled with electrolyte, controlling the rate of charge is very important or the battery will be ruined in short order. Absorbed Glass Mat (AGM) batteries are the latest step in the evolution of lead-acid batteries. Gel and Absorbed Glass Mat batteries are relative newcomers but are rapdily gaining acceptance. Gel and Absorbed Glass Mat (AGM) batteries can dispense charge at a higher rate than flooded cells due to their lower Peukerts exponent. Deep-Cycle Flooded cell battery manufacturers recommend a 4 to 1 ratio between battery bank size and the largest load encountered on board. AGM and Gel cell manufacturers recommend a ratio of at least 3 to 1, a significant difference for loads such as the engine starter or windlass.
The charge acceptance of AGMs can burn up an alternator if the charging system is not adequate for extended runtimes at full power. The higher charge efficiency of AGMs allows you to recharge with less energy: Flooded cells convert 15-20% of the electrical energy into heat instead of potential power. High vibration resistance: The construction of AGMs allows them to be used in environments where other batteries would literally fall to pieces. Thus, there are some significant differences between battery types in terms of features and construction. As we can see from this chart, the purchase cost per amp-hour and purchase cost per cycle still make the Trojan T105 look like the most attractive battery. Premium cells are handicapped by lower energy storage density but offer longer lives and greater resistance to the self destructive habits of lead acid batteries: Thicker lead plates and a more complicated product make it possible.


Perhaps it's shocking condiering their retail prices, but most batteries sold through marine hardware stores do not qualify as premium batteries. WestMarine is offering AGM batteries with a shorter warranty period and higher price than Lifeline AGMs. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. Contact the seller- opens in a new window or tab and request a shipping method to your location. This chart shows the maximum continuous power the battery is rated at divided by its weight.
The cycle life of the battery is used to determine the total kilowatt-hours the battery will deliver over its lifetime and divides that by the original cost of the battery. Since I am selling nothing, I have nothing to gain by skewing these results in any direction.
Using an electrolyte consisting of sulphuric acid, these cells can store impressive amounts of electrical energy in a relatively small space.
Each cell will feature a grid of lead plates along with an electrolyte based on sulphuric acid. The water needs of flooded cells can be reduced via the use of Hydrocaps, which facilitate the recombination of Oxygen and Hydrogen during the charging process.
Furthermore, gel cells use slightly lower charging voltages than flooded cells and thus the set-points for charging equipment have to be adjusted. Instead of using a gel, an AGM uses a fiberglass like separator to hold the electrolyte in place. However, since they are also sealed, charging has to be controlled carefully or they too can be ruined in short order. Deep-cycle Flooded Cells cannot deliver more than 25% of their rated amp-hour capacity in amps without plummeting Available Capacity. The larger the battery bank and the harder the charger is made to work, the more attention I would pay to ensuring that the charging system can handle the currents for extended periods of time. However, there are also some very important figures to consider when it comes to choosing the right battery: Various capacities, cost, warranty, etc. Hence, premium cells usually have a higher resistance to vibration, are easier to service, and have higher cycle lives than their budget competition.
Try to get as much information about your prospective marine batteries before you buy or you'll be sorry. Unfortunately, there are fewer shapes and sizes of VRLAs to chose from (relative to the flooded cell universe anyway), and less familiarity and presence world-wide. Given that reputable brands never claimed more than 600 cycles in the past, the West Marine claim may be a bit dubious. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. In addition, customs duties, taxes and any other applicable charges (if any) are the sole responsibility of the buyer and cannot be refunded.
This is the maximum sustained amperage drawn from a fully charged battery over a certain time period to a point where the battery is at 100% DOD (depth of discharge), for all purposes dead! You may say that this same 200Ah battery should last 4 hours with a 50Amp draw, but this is not the case at all.
While this model of battery is no longer available, similar NiMH batteries are still manufactured by Cobasys. Again, the Tesla battery comes out on top at 7.58 watt-hours per cubic inch and the Deka Dominator loses.


At the battery list demonstrates, cell type batteries do much better in this category than the others.
My main reason for doing this study was to determine the best possible battery for my electric vehicle conversion project. In the marine business, they usually are not sealed so the user can replenish any electrolyte the battery vented while charging the battery.
Since the grid is not supported except at the edges, flooded lead-acid batteries are mechanically the weakest batteries. Furthermore, the thickening agent prevents stratification by preventing the movement of electrolyte.
The physical bond between the separator fibers, the lead plates, and the container make AGMs spill-proof and the most vibration and impact resistant lead-acid batteries available today.
This caveat does not really apply to low-duty applications like starter banks, since they usually need so little charge to be topped up.
The higher charge efficiency of AGMs can contribute to significant savings when it comes to the use of expensive renewable energy sources (wind generators, solar panels, etc.) as your charging system can be 15% smaller (or just charge faster). The Trojan product has thin lead plates that make these batteries lighter but also shorter lived. Many boat owners are willing to put up with the initial purchase price in return for reliability and not having to replace them every few years. Batteries are not created equal and brand or price are not the primary indicator for quality. Furthermore, consider that premium batteries usually only exist in non-standard form factors.
Any return item must be in its original packing, undamaged and in a re-saleable condition, and must not be used. This amperage is then multiplied by the discharge period to give the battery its Ah rating. The reason for this non-linearity is that the capacity of a battery actually decreases when the load increases. The total watt-hour energy of the battery (voltage x amp hours) is divided by the real cost of the battery in US dollars. Initially, I used the Deka Dominator sealed gel batteries which faired quite poorly in these comparisons. Even better, AGMs use almost the same voltage set-points as flooded cells and thus can be used as drop-in replacements for flooded cells.
Even the puny alternators found in Jet Skis should be able to handler an AGM starter battery, as long as that battery is just used for that - starting. Rolls advertises very long pro rata warranty replacement periods for their premium line that are indicative of the confidence they place in their product.
The period of time used to drain and measure the battery is usually 20 hours, although longer or shorter time periods may be used depending on the application. The Trojan battery comes out on top at 8.5 watt-hours per dollar, the lithium batteries are more expensive.
Unless I missing something, these are very expensive and have a much lower cycle life than the Lifeline competition manufactured by Concorde Batteries.
