Deep Cycle Marine Battery - The Best Marine, Automotive and Industrial Batteries

 

odyssey 31m pc2150 1mLead-acid marine and automotive 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, large vessel suitable for long off-shore fishing trips, a city car with an internal combustion engine, or you have large 4x4 SUV/truck for outdoors adventures.

Today, there are several battery types that are commonly used like 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/automotive battery type.

Best CR123A Battery Equivalents and Replacements

cr123a battery mCR123A batteries are lithium 3.0 volts non-rechargeable batteries, characterized by long shelf life, high capacity, low internal resistance, and are commonly used in devices that require bursts of energy and for standby/backup devices.

CR123A batteries are manufactured by many battery brands, that often use different labels for these batteries. Also, while CR123A batteries are Lithium Manganese Dioxide (LiMnO2) 3.0 volts battery, there are several batteries of the same or very similar dimensions, but with different chemistries, having different features and specifications.

ExpertPower EP12200 12V 200Ah Lithium LiFePO4 Deep Cycle Battery

expertpower ep12200 mExpertPower EP12200 is a large, sturdy, powerful, and surprisingly lightweight Lithium Iron Phosphate (LiFePO4) deep cycle battery, designed to endure a large number of charging and discharging cycles, even down to 100% DoD.

As such, ExpertPower EP12200 is suitable as a trolling motor battery, off-the-grid battery, for electric motors and other vehicles, as emergency battery, etc. Although its initial price is higher than the price of similar 12V 200Ah AGM batteries, in the long run, ExpertPower EP12200 actually saves the money ...

How Much Electricity Does a Space Heater Use?

space heater mSpace heaters convert electric energy directly into heat, making them rather inefficient, but simple and affordable units, commonly used for warming up tents, RV, and similar objects when being off-the-grid, but also for quick warming up of rooms and other areas at homes and apartments.

Since they entirely rely on electric energy, many people wonder how much electricity does a space heater use and how they can power such devices while being outdoors.

200 Meters in Miles - Meters to Miles and Miles to Meters Conversion

calculator w150pxmiles to meters w150pxMeters to miles and miles to meters conversions are very often required not only when sailing with a boat, but also in many other situations like when walking, running, trying to figure out the exact distance between two points, and similar.

While many GPS and similar electronic devices offer direct conversion between various units of length (feet, yards, meters, miles, etc.), from time to time there is a need to convert these units directly.

YTX14-BS Powersports Battery Features, Specifications, and Cross Reference Chart

yuasa ytx14 bs w150pxYTX14-BS is a rather popular mid-range Powersports battery, commonly used in motorcycles, scooters, ATVs, snowmobiles, power generators, tractors, and other similar applications as a starting battery for smaller internal (diesel and especially gas) combustion engines.

YTX14-BS is a sealed battery (BS - Battery Sealed), although there are wet/flooded lead-acid batteries made in this size as well, but they are not as common as they used to be. Also, lithium starting batteries that are able to replace the YTX14-BS battery are present on the market as well.

Lithium CR2450 Battery Equivalents and Replacements

panasonic cr2450 w150Lithium CR2450 battery is a very popular button/coin-cell battery, used in various devices that require a compact and reliable source of power with relatively high capacity.

Lithium CR2450 battery is manufactured by most popular brands that often use different labels, leading to slight confusion. Also, several different chemistries are used for making batteries featuring these dimensions, and each chemistry offers different discharge characteristics.

Best BCI Group 34 Battery

odyssey 34m 1500 w150pxBCI Group 34 Batteries are very popular car, boat, and light industry batteries, used in deep-cycle, dual-purpose, and starting/cranking applications.

Most modern group 34 batteries are Sealed Lead-Acid (SLA) Absorbent Glass Mat (AGM) batteries, but flooded batteries are still present. Also, lithium group 34 batteries are becoming more common. But, group 34 AGM batteries are still going on strong, offering a strong and reliable source of electric power at an acceptable price.
