How long will a 165Ah battery last?
The LiTime 12V 165Ah lithium battery offers 2112Wh of energy, with runtime varying based on load power. For instance, it can power a 1100W air conditioner for 1.92 hours, a 900W coffee maker for 2.34 hours, and a 1000W electric grill for 2.11 hours.
What to Do When You Receive a New Battery?
When you receive your new battery, it might arrive with a low state of charge (SOC) due to transport and storage. To ensure optimal performance, it's important to charge the battery right away to prevent over-discharge.
If your battery features Bluetooth functionality, such as the 12V 165Ah lithium battery, it may come powered off, displaying a terminal voltage between 3V and 5V, which means you won't be able to connect it to your phone. This shipping method helps minimize self-discharge and prolongs the battery's lifespan, similar to how mobile phones are shipped.
To resolve this issue, you can use one of two methods: either an AC-DC lithium battery charger or an MPPT solar charge controller. Simply charge the battery for 3 to 10 seconds to enable normal usage.
If you plan to store the battery for an extended period, charge it to a SOC of 50% and perform maintenance checks every three months. This practice will help maintain its functionality and performance.
How to Charge the 12V 165Ah Deep Cycle Battery?
The LiTime 12V 165Ah battery can be charged in four different ways:
1. Solar Panels and Controller
