how long does it take to charge a 200ah battery

Thanks At 1 hour the battery voltage has only risen to 13.8V at a.2C charge rate. We provide a complete line of LiFePO4 12V 100AH batteries for use in boats, solar panels, recreational vehicles, off-grid applications and much more. NICKEL METAL HYDRIDE (NiMH) BATTERY PACK MAINTENANCE 1) If you are having trouble charging a NiMH battery pack, trickle charge it at 1/10C (1/10 its capacity) to wake it up and reach full capacity. Usually, a mid-sized car uses a battery of the size 40-80Ah. Risk of overcharging, out-gasing of hydrogen and hydrogen sulfide at large levels can be expected. Using the example above, 600W of solar panels will charge a 200Ah battery in about 5 hours Charging your battery on a low amperage on a smart charge is fine if you are looking to maintain your battery or keep it on a low charge for a period of time. Forty amps will charge your car quickly and efficiently. Double these times if the battery is fully discharged. It’s not recommended to use this large of a charger. And so on. Your car battery’s rating will be on the sticker on the top of the battery. I’ll let you get back to what you were reading! If you use 2A supply, it’ll take only 100hrs. After jumping a dead battery, drive at least 30 minutes to allow the alternator to bring the battery back to an acceptable level so that it will start again on its own. If you have two 100Ah batteries wired in parallel, you have 200Ah capacity. 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. Double the times if 100% discharged. If you have access to a smart charger, it’s best to hook your car battery to it as soon as possible to bring the battery to a healthy state. The time taken to charge a battery depends on the number of sunshine hours for your location and the power rating of your panels. A car battery usually holds 48 amps so if you take that it charges at approximately 1 amp per hour you can work out how long it will take to charge your battery with various amperage chargers. A slower charge gives the plates in the battery more time with less stress to convert electrical energy from your charger into chemical energy. The 6AH battery needs 3AH recharged, so 3AH/2.5 hours = 1.2 amps per average hour from the 1.5 amp charger. If you have a modern smart charger that has a “float” or “maintain” mode, you can leave these hooked up indefinitely, as they only give out current when the battery naturally self-discharges. It’s usually an easy problem to remedy if you can get a jump from another car. Now back to your question, how long to charge a 200ah,12v battery, it all depends on the charger you're using and to which voltage you last consumed your battery. Anonymous. The ideal charging voltage for a calcium battery is 14.8V for the recombination process to properly occur.. I think 5-amps is the sweet spot when it comes to vehicle batteries. Most car batteries are in the range of 40 to 60 amp hour equivalency. A 4 amp charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 6 to 7 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 7 to 9 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 9 to 17 hours. How long does it take to charge a deep-cycle battery? in about 3 to 4 hours duration. No, A car battery charger on trickle charge is too low to do the job. If this was your alternator it had better be robust enough to deliver its full output for at least 1 hour straight. Stage 1 battery charging is typically done at 30%-100% (0.3C to 1.0C) current of the capacity rating of the battery. I essentially extrapolated their chart that they use for their 1.5 amp charger to get a baseline for all of the other values. 32AH / 2 = 16AH that needs to be replaced. Home Battery Bank is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. This type of amperage is used when using a trickle charger or just maintaining your battery at a certain level and not trying to get a quick charge to boost your battery and get it started. If using a low amp charger it can take up to 24 hours to charge your battery properly but a high amperage charger such as a 40 amp charger will get the job done adequately in an hour or less, and will get you on the road again in only a few minutes. A 2 amp trickle charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 11 to 14 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 14 to 18 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 18 to 35 hours. Knowing how long you might be without a vehicle and making plans around that might make your day a little better though. I’ve brought a few batteries back to life in this manner that were undetectable by smart chargers. 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. With the given examples, they all lead to this formula: “X”AH /time of charge listed = 1.2. This also applies to batteries that have been in long term storage. If the battery is fully empty, then you just need to double these times to … Batteries will tend to overheat, overcharge, and “boil” electrolyte off when they are receiving an amperage greater than 25% of their total amp hour rating. Structural damage to the battery is a great possibility. Do not use this large of a charger for car batteries. Home Battery Bank is compensated for referring traffic and business to these companies. If the battery is completely discharged, you will likely need to jump the battery from another vehicle for a few minutes first to give it a temporary spike in voltage so that a smart charger can recognize the battery. Then take the battery capacity which measured in AH and divide it by the amp rating (the result from prior computation) of the solar panel and then adding 10% of the Charging Time to it. In the chart seen here (which assumes that you are only recharging a battery from 50% – not dead), you’ll notice that the first two categories are in Amp Hours (AH) but that car batteries are rated in Cold Cranking Amps (CCA) or Reserve Capacity (RC). 10 amps are needed for Deep Cycle Marine Batteries. Yes, a trickle charger that is not a “smart charger” operating in “float” mode will eventually ruin your battery if left connected over time. The 12-hour battery at 50% needs 6 amp hours recharged. A 1.5 amp trickle charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 15 to 19 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 19 to 25 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 24 to 46 hours. Double the times if 100% discharged. A standard 100 amp hour battery on a 15 amp charger at room temperature, will typically take around 5.33 hours to reach 80% capacity. So, make sure you choose the correct charger for your battery. The real question should be how many hours would x watts solar panel take to charge 200ah battery Because its current that really determines how fast the battery charges, that means even a 40 watt panel would charge your battery, just that it would take longer . 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.
