Frequently Asked Questions - WB-2000-2 TOA

What type of battery is the TOA WB-2000-2?

The TOA WB-2000-2 is a rechargeable nickel-metal hydride (Ni-MH) battery typically used in emergency lighting and alarm systems.

What is the voltage and capacity of the WB-2000-2?

It has a nominal voltage of 12V and a capacity of 2000 mAh (2.0 Ah).

How do I charge the WB-2000-2 battery?

Use a compatible 12V Ni-MH charger with a recommended charging current between 0.5A and 1A. Do not exceed 1A to avoid overheating.

Can I replace the battery myself?

Yes, if you have basic electrical skills. Ensure the device is disconnected from power. The battery uses Faston terminals for easy connection. Always observe polarity (+/-).

What is the expected lifespan of this battery?

Under normal use, the WB-2000-2 can last for up to 500 charge/discharge cycles (approximately 3-5 years depending on usage).

How should I store the battery when not in use?

Store in a cool, dry place at temperatures between -20°C and 40°C. Recharge every 6 months to prevent deep discharge.

What devices are compatible with the WB-2000-2?

It is designed for TOA emergency lighting, alarm panels, backup power supplies and similar systems that use a 12V battery with Faston terminals.

Is the WB-2000-2 battery maintenance-free?

Ni-MH batteries require minimal maintenance. Keep the terminals clean and corrosion-free. If the battery is idle, perform a full charge every 6 months.

What safety precautions should I take?

Do not short-circuit, disassemble, or expose to fire. Overcharging can cause damage; use only chargers designed for Ni-MH batteries. Dispose of batteries properly at authorized recycling centers.

How do I dispose of the battery?

1. SAFETY PRECAUTIONS

DANGER

Indicates an imminently hazardous situation, which, if not avoided, will result in death or serious injury.

• Do not deform nor solder.
• Do not short-circuit.
• Do not heat nor put in fire.
• Do not dip into water nor wet the battery terminals.
• Do not use nor keep near fire or in locations where the temperature rises above 60^ (140°F) such as in a sun-heated car.
• Use the BC-5000-2, BC-5000-6, or BC-5000-12 Battery Charger when recharging.
• Use only with the specified equipment.
• Do not drop nor give a shock.
• If battery leakage gets in one's eyes, wash it away with clean water and consult a doctor immediately. Doing otherwise may cause one's eyesight loss.

WARNING

Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury.

• Stop charging if the battery are not fully charged within 3 hours.
• The temperature of battery sometimes rises high just after use. When removing from the unit, switch off the unit's power and let the battery cool down to an ambient temperature.
• Charge when using first after purchase or when using after left unused for a long period of time.
• Battery operating duration may be short due to its self-discharge when left unused for a long period of time even after fully charged.
• Using at room temperature (20±5°C or 68±9°F) is recommended. Using at 10°C (50°F) or below will extremely reduce the battery operating duration.
• Once overdischarged, its usable capacity could not restore even after charge. So, charging for about 5 minutes every 6 months is advisable when leaving it unused for a long period of time.
• Do not recharge fully-charged battery. Doing so deteriorates its performance.
• When not in use, take it out of the unit, and store in locations free from moisture and between -20^ and 30^ (-4°F and 86°F).
• Do not store in a fully charged state. Discharging as fully as possible before storage is recommended. (Note that doing this will not lead to overdischarge of the battery.)
