#DEEP CYCLE BATTERY BOX PORTABLE#
This is particularly important if you are using portable solar panels to charge the battery, due to the possibility of inclement weather.I got the deep cycle battery and a bunch of useful tools (including a cordless drill) for Christmas.I asked for the gift card but not for the tools which was a pleasant surprise. The greater the capacity, the more power you have in reserve. You would select a deep cycle battery with a capacity of at least 76.5Ah. For example:ġ x set LED camp lights (3A per hour) x 5 hours = 15Ahġ x portable fridge (1.5A per hour) x 24 hours = 36AhĪdd a safety net (say 50%) = 51Ah x 1.5 = 76.5Ah To calculate your requirements, consider the current draw of each piece of electrical equipment you wish to run from the battery. This measure represents how long one Ampere of current can flow out of the battery. Battery Capacity & Calculating Requirementsīattery capacity is measured in Ampere hours (Ah). Gel Lead Acid Batteries are similar to wet cell batteries but have a gel-based electrolyte, which eliminates evaporation and makes them much more resistant to extreme temperatures and vibration. There are also a couple of other types available:įlooded Lead Acid batteries (wet cell) were the first type of deep cycle battery produced, and they are still somewhat popular today due primarily to their low cost, despite being heavy and maintenance-intensive making them unsuitable for use as a boat battery Other TypesĪGM and Lithium are the most common types of deep cycle batteries on the market. More so on boats, but also in caravans, weight is an important factor and Lithium is by far the best marine battery or caravan battery for sale today. They will charge to more than 90% of capacity in 1-3 hours, compared to SLA batteries which will generally charge to around 80% of capacity in around 5-8 hours. Lithium batteries have extremely low internal resistance, meaning they can charge very quickly and efficiently. They can handle up to 8 times as many charge cycles as an SLA battery, and can discharge very close to 100% of their capacity without damaging the cells, compared to just over 50% for SLA batteries.
Firstly, they are much lighter, generally weighing about one-third to half that of equivalent capacity SLA’s. The advantages of lithium deep cycle batteries compared to their sealed lead acid (SLA) forebears are numerous. Lithium batteries are generally composed of Lithium Iron Phosphate (LiFePO4), which is considered the best battery material available on the market today. The Lithium deep cycle battery represents the very latest in battery technology. This makes AGM a great choice for use as a marine battery or boat battery. An AGM battery is also maintenance-free, in that it does not require topping up with distilled water like wet cell batteries.
It does not have to be mounted upright in a sealed container vented to the outside rather, it can be mounted either on its sides or on its ends and can vent to the atmosphere. Compared to wet cell batteries, AGM deep cycle batteries can handle higher temperatures, will self-discharge at a much lower rate, and have lower internal resistance, meaning they can accept a higher charge current and thus will charge more quickly.īecause the AGM battery is fully sealed, it is much easier and safer to transport. The AGM battery (Absorbent Glass Mat) contains electrolytes which has been absorbed into porous fibreglass mats. For the ultimate in performance and for serious off-road adventure enthusiasts, lithium is the best deep cycle battery money can buy. What’s The Best Deep Cycle Battery For Camping?įor 4×4 recreational use with a solar camping setup an AGM battery is adequate and by far the most popular choice due to the price point. They are commonly used as 4×4 batteries, caravan batteries, recreational vehicle batteries, marine batteries and in dual-battery systems. Uses of Deep Cycle Batteriesĭeep cycle batteries are employed for use in situations where steady, low-current power delivery is required. Physically, the main differences between deep cycle and starter batteries is that the deep cycle battery has thicker battery plates and denser active paste material, allowing it to withstand the deeper charge cycles. It can also be discharged to less than half of its capacity for many charge cycles. for starting a car engine), a deep cycle battery is designed to deliver sustained, lower-current power over a long period of time. In contrast to starter batteries, which are designed to be constantly topped up and deliver short, high-current bursts of power (e.g.
Deep cycle batteries, sometimes also referred to as deep cell batteries, are designed to be deeply discharged on a regular basis.
