How to Choose the Right R23 Battery
1. Identify Your Device/Application Requirements
- Check Voltage & Chemistry: Make sure the new battery matches the operating voltage and chemistry your device or system requires.
- Form Factor: Size and shape must fit your device’s battery compartment.
2. Understand Your Use Case
- For Remotes & Small Devices: Use standard 23A alkaline batteries.
- For Radios: Determine if your device requires a PP9, and consider rechargeable alternatives or home-built adaptors (e.g., a 6xAA holder).
- For Laptops: Choose a replacement Li-ion battery that matches the original specs (voltage, capacity, connector, shape).
- For Marine/RV: Assess your average/peak power needs, physical installation space, and charging setup (e.g., if you require lithium for weight/capacity or can benefit from advanced features like DC-DC charging and solar integration).
3. Assess Battery Chemistry Options
- Alkaline: Best for infrequent, short-duration, or high-drain tasks in small devices.
- NiMH Rechargeable: Great for users seeking an eco-friendly, reusable option for radios (may require adapters).
- Lithium-Ion (Li-ion or LiFePO4): Ideal for long-term, high-capacity needs—excellent for laptops and advanced marine/house bank upgrades.
4. Consider Longevity and Expense
- Longevity: Lithium and modern rechargeables tend to last far longer per dollar spent, but upfront cost is higher.
5. Assess Availability
- Some battery types (e.g., PP9s) can be harder to find; check local hardware stores, specialist shops, or prepare to convert your device.
Practical Tips, Advice & Best Practices
For Everyday Device Users
- Match the Battery Exactly: Always check model numbers, voltage, and polarity.
- Store Spares: For devices like garage remotes, keep an extra 23A battery on hand.
- Dispose Responsibly: Recycle used batteries where facilities exist.
For Vintage Radio Enthusiasts
- Adapt for Modern Batteries: Consider converting the radio to use PP3 (9V) or 6xAA holders if PP9 is hard to find or expensive.
- Use Rechargeables: If regularly used, opt for NiMH rechargeables in suitable adapters.
- Check Local Shops: Sometimes, local hardware stores still stock PP9s at reasonable prices.
For Laptop Owners
- Buy From Reputable Sellers: Ensure you’re purchasing a genuine or certified compatible battery.
- Verify Fit & Specs: Confirm model, voltage (14.8V for Samsung R23), current, and connector.
- Follow Charging Guidelines: Don’t overcharge or let the battery drain to zero. Store Li-ion batteries partially charged if not used for extended periods.
For Marine/RV/House Bank Upgrades
- Plan The System Holistically: Upgrading to lithium involves more than just swapping batteries. Assess chargers, solar controllers, and alternator compatibility.
- Do Not Mix Chemistry: Do not mix lead-acid and lithium in the same bank unless you have separate, properly configured chargers/DC-DC converters for each type.
- Include Safety Gear: Use proper fusing, battery management systems (BMS), and high-quality cabling.
- Consider Solar Expansion: Pairing lithium with upgraded solar can provide exceptional off-grid potential.
- Professional Installation: If in doubt, consult a marine/RV electrician for complex upgrades.
