Q: Can I connect a 100 Ah battery to a 200 Ah battery?
A: Unfortunately, you cannot mix different types of batteries. It is crucial that all batteries you connect share the same capacity (Ah), voltage (V), and most importantly, the same type (AGM). For optimal performance, it's best if they are from the same brand.
4. Q: What's the best way to place and store this battery?
A: This is a sealed battery, and we recommend placing it upright. You may place and install it on its side only for specific reasons. However, DO NOT place the battery upside down. Store the battery in a dry, cool environment (5°F~104°F / -15°C~40°C). Ensure it is fully charged before storing and recharge it every three months to maintain its health.
Q: Can I discharge the battery to 0% and then recharge it again?
A: To maximize the battery's lifespan, avoid discharging it below 50%. Before storing the battery, fully charge it to 100%, and recharge it every three months.
Q: I will be living in my forest cabin during the winter holidays. Can this battery be used at freezing temperatures?
A: The battery's discharge working temperature range is 5°F~122°F (-15°C~50°C), and the charge temperature range is 5°F~104°F (-15°C~40°C). Operating the battery outside of these ranges can significantly reduce its lifespan. Before using the battery, please verify the daily temperatures at your location to ensure it falls within the acceptable range for this AGM battery.
Q:
Would 2 100Ah batteries be better or the same as 1 of the 200Ah?
A:
In terms of capacity, they are equivalent. However, having 2 100Ah batteries is advantageous over 1 200Ah battery. If one 200Ah battery fails, you're left without a backup. With 2 100Ah batteries, if one fails, you still have the other to rely on, providing greater reliability.
Q:
I am using 17kW of power per day. How many of these batteries will I need for my power bank?
A:
To calculate: 17 kilowatt hours (kWh) divided by 12 volts equals approximately 1417 amp hours. Given that batteries should not be discharged more than 50% to maintain a reasonable service life, you would require around 2834 amp hours of rated capacity at 12 volts. This translates to needing 15 of the 200Ah batteries (or 29 100Ah batteries). Additionally, ensure you have a charging capacity of approximately 20 kWh (1700Ah @ 12 volts) per day to cover both storage and discharge inefficiencies.
