An 8 amp charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 3 to 4 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 4 to 5 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 5 to 9 hours. Source(s): long charge 12v 200ah deep cycle battery 125 watt solar panel: https://biturl.im/KGBev. Structural damage to the battery is a great possibility. Black wire or the red... Hi! This slowly evaporates the electrolyte through electrolysis (overcharging). Knowing how long you might be without a vehicle and making plans around that might make your day a little better though. Simple you need at least C/10 charge current (20-Amps). Do not use this large of a charger for car batteries. If you are using a smart car charger it will reduce the amperage as soon as the full charge is reached from 40 amps down to a trickle just for maintenance or switch off completely once charged, these are the best options to use. Often trickle chargers are used in workshops to maintain batteries while the mechanic works on the car, especially if the battery is going to stand disconnected for a period of time, this is so that the battery keeps enough charge to be functional when put back into the car for use. If we apply the same logic to the CCA/RC batteries, we can see that it takes 19.25 hours to charge a 315CCA or 60RC battery from 50%. The time taken to charge a battery depends on the number of sunshine hours for your location and the power rating of your panels. The reason your smart charger won’t begin the charging process is because of its built-in safety feature. If you’re looking for a solid charger and/or maintainer, I recommend this 5-amp charger from Amazon.  It is gentle on your car battery, can charge it overnight, and can be left connected indefinitely for long-term storage! If the battery is fully empty, then you just need to double these times to … Of course, these are all estimations that do try to factor in inefficiencies but battery science is extremely complex and full of theories, laws, and estimations. If this doesn’t work, you can repeat the process a couple of times for longer durations when connected to the donor vehicle. It also increases the production of hydrogen gas (explosive) and hydrogen sulfide (H2S, noxious). (adsbygoogle = window.adsbygoogle || []).push({}); Trickle chargers are mainly used to maintain your charge on your battery over a period of time so that it never runs out of charge and you are never left stranded with a flat battery. Working with electricity can be deadly if you are not careful. I continued to do all of this math for all of the values and reached 36AH to 46.2AH, 46.2AH to 58.8AH, and 58.8AH to 111AH for the battery ranges for Car/Truck batteries. It’s not recommended to use this large of a charger. Shop now! A 6 amp charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 4 to 5 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 5 to 6 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 6 to 12 hours. I have a 6V 4.5 battery and a solar panel 6V and a trail Camera 1000-2000ma how long will it take to charge the battery or can I put a 12V solar panel on a 6V Battery and the camera will it blow it up or not the 12V solar panel vpm-17.3 VDC VOC-21.3 VDC IMP-0.3 Amps ISC.0.33 Amps the camera 1000-2000 MA converter on it. The reason it averages out to 1.2 amps per hour instead of 1.5 is the increasing internal resistance from the car battery as it approaches full charge. If you have a 50AH battery and you hook a 30 amp charger to it, you are risking overheating it, warping the plates, and losing electrolyte solution through evaporation due to electrolysis. HOW LONG TO CHARGE A BATTERY: WHAT MAKES THE TIME VARY. Trickle chargers continue to pump a small current into the battery even if the battery can’t accept it. Home Battery Bank also participates in advertising through Google AdSense and Ezoic. Mid-sized car batteries can be charged in 31 hours at 2 amps, or 6 hours at 10 amps. So it is pretty much crucial to know how to charge a deep cycle battery properly. So, make sure you choose the correct charger for your battery. And How long to charge a deep cycle battery? In fact, I would stay in the 2 to 8 amp range. Obviously, it is the advance characteristics that separate it from other.Even its manufacturing materials are standard and ahead of others in quality. Sunshine hour =8hr These my questions 1. Forty amps will charge your car quickly and efficiently. The charger can charge a 50% discharged medium-sized battery, which is RC 60-85, in about 3 to 4 hours, or a large-sized battery, which is RC 85-190, in approximately 4-7 hours.
