Rayovac Batteries

Rayovac Batteries at a Glance

Rayovac offers a full range of batteries for home and professional use, including alkaline (AA, AAA, C, D, 9V), NiMH rechargeables (AA/AAA), and specialty options such as hearing aid cells. The brand focuses on dependable power, broad device compatibility, and strong value—especially in multi-packs.

Product Lines and Use Cases

• High Energy (Alkaline): Everyday devices like remotes, toys, clocks, flashlights, and basic cameras.
• Fusion (Alkaline): Premium alkaline option for higher-drain gear such as gaming controllers and LED flashlights.
• Ultra Pro (Alkaline): Bulk packs for job sites, facilities, and high-volume users; convenient for standardized replenishment.
• Recharge (NiMH): Best for frequently used, power-hungry devices (game controllers, flash units, wireless peripherals). Recharge hundreds of cycles with a compatible NiMH charger.
• Hearing Aid Batteries (Zinc-Air): Sizes 10, 13, 312, 675 for modern hearing aids. Activate by removing the tab and allowing air to start the reaction.

When to Choose Which Rayovac Battery

Alkaline (High Energy, Fusion, Ultra Pro)

• Use if: You need reliable, ready-to-use power for low- to moderate-drain devices (remotes, clocks, toys, radios, basic flashlights).
• Avoid if: Your device is very high-drain or used continuously (camera flashes, pro audio packs). Rechargeable NiMH is often more cost-effective here.

Recharge (NiMH)

• Use if: You cycle batteries often in high- or moderate-drain gear (gaming controllers, wireless mice/keyboards, LED lights, cameras).
• Avoid if: The device sits unused for months; alkalines hold charge longer on the shelf.

Specialty/Hearing Aid

• Use if: Your device specifies zinc-air hearing aid sizes (10/13/312/675). Follow the device manual for size and replacement intervals.
• Avoid if: You need rechargeable chemistries; most hearing aid cells are single-use.

Expected Performance and Runtime Examples

Actual runtime varies by device, settings, and temperature. Use these ballpark figures to plan:

Device/Scenario	Recommended Type	Typical Outcome
TV remote (low drain)	Alkaline (High Energy)	6–12+ months per set
Wireless mouse/keyboard	Alkaline or Recharge (NiMH)	Alkaline: weeks–months; NiMH: days–weeks per charge
Game controller	Fusion (alkaline) or Recharge (NiMH)	Alkaline: ~10–30 hours; NiMH (2000–2500 mAh): ~15–40 hours per charge
LED flashlight (100–200 lm)	Fusion (alkaline) or Recharge (NiMH)	Alkaline: ~2–8 hours; NiMH: ~2–6 hours per charge
Smoke/CO alarm	9V Alkaline (High Energy)	Often 6–12 months; follow device guidance
Camera flash / wireless mic packs	Recharge (NiMH)	Faster recycle times and stable voltage vs. alkaline

Cold weather note: Alkaline performance drops in freezing temperatures; keep spares warm and consider chemistries recommended by your device for extreme cold.

Buying and Storage Tips

• Check the date code: Choose the latest expiration date for longer shelf life (up to 10 years on select AA/AAA; 9V and other sizes may differ).
• Match chemistry to duty cycle: Alkaline for occasional/low-drain use; NiMH rechargeables for frequent/high-drain use.
• Right-size your pack: Multi-packs reduce cost per battery if you use them within their shelf life.
• Storage: Keep in original packaging, at room temperature, dry, and away from metal objects. Do not refrigerate or freeze.

Safety and Care

• Do not mix old and new batteries or different brands/chemistries within the same device.
• Insert with correct polarity. Remove batteries from devices stored long-term.
• Never attempt to recharge alkaline or non-rechargeable batteries.
• If a battery leaks, wear gloves, avoid contact with skin/eyes, and dispose of the battery safely; clean the device per manufacturer guidance.
• Button and hearing aid batteries are a choking hazard—keep away from children and pets; seek immediate medical help if swallowed.
• Recycle when possible per local regulations; use community battery recycling programs for NiMH and single-use cells.

FAQ

• How long do Rayovac alkaline batteries last in storage?
  Select AA/AAA list up to a 10-year shelf life when stored properly. Check packaging for size-specific shelf life.
• Can I use Rayovac Recharge in any charger?
  Use a charger designed for NiMH cells. Avoid charging any non-rechargeable batteries.
• What’s the difference between High Energy, Fusion, and Ultra Pro?
  All are alkaline. High Energy suits everyday devices, Fusion is a premium alkaline for higher-drain use, and Ultra Pro is typically bulk packaging for professional or high-volume needs.
• Are Rayovac batteries leak-resistant?
  They’re designed with leak-resistant features, but any alkaline can leak over time. Follow storage best practices and replace batteries before the expiration date.
• Which batteries should I use for smoke alarms?
  Many smoke/CO alarms use 9V alkaline. Follow the alarm manufacturer’s guidance and replace on the recommended schedule.
