The Optima BlueTop is designed for both starting and deep-cycle use. It can withstand over 400 charge and discharge cycles over its lifetime at 80% discharge. The main reason why we recommend this battery is its resiliency. Thin-plate batteries have 15% more surface area to allow better contact with the acid. This battery uses a unique flooded design uses thin-plate technology. Many people report long-lasting performance with this battery. The Banshee 31 is recommended for its reliability and starting ability in any condition. This battery is completely sealed, so you never have to add water. You never have to worry about surprises, and you can have plenty of warning to get a new one before it leaves you stranded. This battery has a built-in hydrometer that lets you know how much battery life is left. It can be used on many fast chargers without damaging the battery, and it can also withstand many long, slow recharge cycles. This battery is designed with dual terminals. It uses enhanced flooded technology intended for deep-cycle use. This is the only flooded battery that made the list. This battery has a durable case and can withstand heavy vibration and shocks, making it a good choice for off-road and recreational vehicles. NorthStar has a state-of-the-art plant with excellent quality standards and consistency. NorthStar batteries are always a good choice because they are so well made they can be transported as non-hazardous by ground, sea, or air. It is rated as a dual-purpose battery, but it's a better starting battery in actual use. One thing to note is that this battery tends to have an excellent initial burst, but it then tends to drop voltage quickly. It is also a good choice for engines that have a few miles on them, which might be more difficult to start. This battery has a fast discharge upon starting, which means that the engine will turn over quickly. It's rated for over 900 recharges at a 50% discharge depth. This battery has excellent cold-cranking ability and a spill-proof design. NorthStar batteries are known for their excellence in performance and proven long-life. The battery uses heavy-duty lead calcium-alloy grids that provide an extra boost of performance and extend the service life. Its highly-efficient design is stable and reliable over time. Banshee batteries use a unique design that controls the output of gas and allows recombination and recovery of over 90% of the gas generated. The battery has a low-pressure venting system and a high recovery rate to withstand deep-cycle charging and fast charging better than most. This battery is recommended for boats, marine applications, and RVs, and it's an excellent choice for boats that only get seasonal use. One thing that stands out is that it has a low self-discharge rate and can withstand long-term storage. It's maintenance free, and you do not have to add water regularly. This Banshee battery is a rechargeable deep-cycle battery that uses sealed AGM technology. Technical specifications: Cold Cranking Amps (CCA)
