Q: Is it possible to connect a 100 Ah battery to a 200 Ah battery?
A: Unfortunately, no. Connecting batteries with different capacities (Ah), voltages (V), or types (e.g., AGM) is not advisable. For optimal performance and safety, always ensure that all connected batteries are of identical brand, capacity, voltage, and type.
4. Q: What is the recommended method for placing and storing this battery?
A: It's best to place this sealed battery upright. While it can be installed on its side if necessary, it should never be placed upside down. Store it in a dry, cool environment (5°F~104°F / -15°C~40°C). Make sure the battery is fully charged before storing and recharge it every three months to maintain optimal condition.
Q: Can I fully discharge the battery to 0% and then recharge it?
A: To ensure maximum cycle life, avoid discharging below 50%. If the battery is not in use, fully charge it before storing and recharge every three months to keep it in top shape.
Q: I'll be staying in my forest cabin during the winter holidays. Can this battery operate in freezing temperatures?
A: The battery functions within a discharge temperature range of 5°F~122°F (-15°C~50°C) and a charge range of 5°F~104°F (-15°C~40°C). Operating outside these ranges can reduce its lifespan. Check the daily temperatures of your cabin's location before using this battery to ensure optimal performance.
Q: Can you advise if two 100Ah batteries are better than one 200Ah battery?
Would 2 100Ah batteries be better or equivalent to a single 200Ah battery?
A: Given the same capacity, two 100Ah batteries are often better. If one fails, the other can still provide power, whereas with a single 200Ah battery, a failure means you lose all power.
In terms of capacity, they're the same, but having two 100Ah batteries offers a backup solution. If one fails, the other continues to supply power, unlike a single 200Ah battery which leaves you powerless if it malfunctions.
Q:
I consume 17kWh per day. How many of these batteries would I need for my power bank?
A:
To support your 17kWh daily usage at 12 volts, you'll need 1417 amp hours. To extend battery life with a maximum 50% discharge, you'll require 2834 amp hours. This equates to 15 batteries of 200Ah each or 29 batteries of 100Ah each. Additionally, ensure you have about 20kWh (1700Ah @ 12 volts) of daily charging capacity to account for storage and discharge inefficiencies.
