Deep Cycle, Dual Purpose, and Starting Marine, Vehicle and Solar Batteries and Chargers
Lead-acid marine batteries are a very important piece of equipment, regardless if you have a small boat that can be pulled out on dry land by hands, or you have large vessel suitable for long off-shore fishing trips.
Today, there are several battery types that are used on fishing boats: Lead Acid batteries, Nickel-Cadmium batteries, Nickel Metal Hydride batteries, Lithium batteries, etc.
Non-lead acid battery types do have their advantages, but so do the lead-acid batteries and they are still the most used marine battery type.

Lithium 3.0V CR2032 is one of the most popular lithium, non-rechargeable, button/coin cell batteries, commonly used in watches, calculators, security applications, medical devices, wearable electronics, CMOS memory battery, etc.
Although CR2032 is widely spread and can be easily found at online shops and various hardware stores, many manufacturers use their own labels, leading to some confusion among the users.
Mighty Max ML75-12 is a general-purpose SLA AGM battery featuring a nominal capacity of 75 Ah and a nominal voltage of 12 volts - hence the label 'ML75-12'.
As a Sealed Lead Acid (SLA) Absorbent Glass Mat (AGM) battery, Mighty Max ML75-12 battery features spill-proof design and can operate in almost any position - don't use it upside-down, although Owner's Manual says 'any position'.
This maintenance-free, deep-discharge battery is one of the most popular Group 24 batteries, thanks to the acceptable price, reliable operation, and sturdy design.
CR-P2 is a very popular non-rechargeable 6V battery, commonly used in photo equipment, but also for powering other electronic devices that require a stable power source able to provide strong currents even after long periods of time being stored away.
CR-P2 battery is the most common label, but other labels are used as well, including BR-P2 battery, 5024LC battery, 223A battery, CR17-33 battery, etc. Fortunately, in order to avoid confusion, most brands use CR-P2 and 223A labels practically always.
CR123A battery is a very popular lithium cylindrical battery commonly used in high drain and standby devices like photo cameras, flashlights, toys, and similar.
Non-rechargeable CR123A lithium-ion battery offers great capacity, high-drain currents, and rather long shelf-life, while rechargeable CR123A or commonly labeled as RCR123A offers a large number of charging/discharging cycles combined with moderate capacity, while drain currents depend on the battery design.
SR626SW batteries are button/coin-cell batteries commonly used in wristwatches, calculators, medical instruments, laser pointers, LED micro-flashlights, and similar.
SR626SW batteries are manufactured by most battery brands but often feature different labels, leading to certain confusion among their buyers.
LR41, SR41, AG3, 392, and 312 batteries are non-rechargeable button/coin-cell batteries often used in calculators, thermometers, micro LED flashlights, toys, wearable electronics, and similar devices.
