⚠️ Usage Notes & Precautions
To ensure optimal safety and longevity:
1️⃣Avoid High Temperatures: Exposure above 60°C or direct sunlight can cause swelling (puffing).
2️⃣ Low-Power Use Only: Capacity is modest—designed for low-current devices, not for motorized or high-drain tools.
3️⃣ Proper Storage: For long-term storage, maintain 40–60% charge (≈3.7–3.8V) and recharge every 3 months.
4️⃣ Avoid Overcharge/Over-discharge: Use proper LiPo chargers with protection circuits to extend service life.
5️⃣ Use CC/CV Charging: Always use a constant-current/constant-voltage charger to ensure stability and safety.
❓ FAQ – Frequently Asked Questions
Q1: Does this LiPo battery have a memory effect?
A: No. LiPo batteries are free from memory effect, so you can charge or discharge them at any time without degrading capacity.
Q2: How can I tell if the battery is fully charged?
A: When charged using a proper CC/CV charger, the battery reaches 4.2V, and the charging current naturally tapers to near zero—indicating full charge.
Q3: Is there any risk of leakage?
A: No liquid electrolyte is present, so leakage risk is minimal. However, physical damage or exposure to high heat may cause swelling or venting.
Q4: What charging method should I use?
A5: Always use a CC/CV (Constant Current/Constant Voltage) charger designed for 3.7V LiPo batteries to maintain battery health and prevent damage.
Q5: What is the self-discharge rate of this battery?
A: The 501525 LiPo battery has a low self-discharge rate of less than 1% per month, making it ideal for long standby or intermittent-use devices.
