Top best answers to the question «Should you charge a new marine battery»
New batteries should be given a full charge before use. New deep cycle batteries need to be cycled several times before reaching full capacity (50 - 125 cycles, depending on type)… Batteries should always be watered after charging unless plates are exposed before charging.

Make note that quick charging marine batteries on a regular basis will decrease the life of the battery. No more than one charge per day should be given. The battery should also be allowed to cool off before use. Quick charging can cause extra heating.
Re: Do I need to charge a new marine deep cycle battery? I don't know of any way to monitor battery voltage while charging to determine when the battery is fully charged. If you don't already have one, buy yourself a smart charger with an max output of between 5 and 15 amps. Charge the new battery for at least 24 hours.
Re: New battery, should I charge it first? NO do not! If its got a charge you need to run it allllllll the way down. This is a rechargeable battery just like on your cell phone..... First time u use it run it all the way down other wise it
So, usually, a marine battery is found with dust and waste. That’s the reason, before charging your battery, it’s necessary to check and clean the battery correctly. Very first, carefully reach your battery, switch off it, and remove it from the battery box.
Most people recommend that for a marine starting battery you use the conventional battery charge instead of the deep cycle charge that you may give to other marine batteries. If you need a quick charge to use it the next day, using the 10amp setting will give it the burst of power that it needs.
Essential to marine battery maintenance is proper charging so always use a charger that meets the manufacturer’s recommendations. Regularly under-charging a battery erodes its performance and reduces its life due to a phenomenon called sulfation.
Once fully charged, marine batteries should be held at a considerably lower voltage to maintain their charge - typically 13.2 to 13.4 volts. Higher voltage levels will "gas" the battery and boil off electrolyte, again shortening battery life.
When you first plug in your Minn Kota onboard charger, your batteries will enter the Bulk Charging phase, when the highest charge voltage and current will be applied to restore battery charge, typically up to a point of 80% of the battery’s capacity. It is during this phase that the maximum charge voltage and current output of your onboard ...
Deep Cycle Batteries in a cycling application require a recharging voltage of 2.43 to 2.45 volts per cell. This is 14.6/14.7 volts for a 12 volt nominal installation and 29.2/29.4 volts in a 24 volt site. Secondly, how many volts should a marine battery have? The voltage on a fully charged battery should be about 12.7-12.8 volts.
