Yes, it is normal. When the charger is transferring energy into the battery, it warms both the cells and charger up. Battery will return to room temperature within minutes after the charging process stops.

It will require a plug adaptor, but not a voltage converter. (The ATC chargers voltage ranges from is 100 – 240 volts, 50/ 60Hz).

Yes. All ATC Ni-MH batteries can be charged in ATC chargers. Longer charging time is needed for larger capacity batteries.

ATC charger is able to charge other Ni-MH AA or AAA batteries. However we recommend using only ATC batteries within your ATC charger as ATC cannot guarantee the performance, quality and safety of batteries from other brands.

Yes. ATC Ni-MH batteries can be used in regular devices as long as the size is correct. However ATC suggests referring your device user manual for compatibility. Ni-MH batteries are most suitable to high-drain devices, e.g. digital cameras, which usually consume regular alkaline batteries in a short period of time.

When the normal charge is complete, ATC chargers will switch to a trickle charge. When it is not in use, ATC recommends unplugging the charger.

Yes, because of ATC's built in safety features, batteries can stay in the charger overnight safely. ATC recommends unplugging the charger after use.

Memory effect does not occur on Ni-MH batteries and they can be charged even when they are not completely discharged. If batteries have been stored for more than one month, you should recharge them before using in order to maximize the power.

No. Please do not mix old and new batteries.

No, capacities of the batteries used within your device should be the same.

Yes. Charging of new batteries is recommended to guarantee better performance as they are not fully charged upon purchase. The first charging time should be shorter than usual as they are, on the other hand, not fully discharged. In fact, charging 2-3 times of Ni-MH batteries is required before delivering the best performance.

You can recharge them for more than few hundred times. The cycle life of Ni-MH battery depends on factors like shelf life, temperature and storage conditions. The number of charges available vary is affected by charger you use. In general, slow chargers can prolong the cycle life and increase the lifetime to more than 500 charges while fast chargers may shorten the life time to 150 charges.

Our suggestion:

Both of them are rechargeable, but Ni-MH batteries equipped with higher energy density and provide up to 4 times the electricity of older Ni-Cd batteries for each charge.

mAh (milli-amp-hour) ratings indicate the power capacity of the Ni-MH batteries battery. The higher the capacity, the more long-lasting the battery will be between charges.

All Ni-MH batteries lose their charge when leaving idle. However, the capacity loss rates are different. Some of them self-discharge at a rate around 1.5% per day. ATC Rechargeable batteries lose charges at a rate of about 0.5% per day. Generally speaking, Ni-MH rechargeable batteries can be stored up to 3 years under a relatively environmentally controlled condition.

alkaline batteries are not rechargeable and should never be placed in any battery charger.

ATC recommends not using chargers from other brands to charge ATC Ni-MH Rechargeable batteries. The performance of ATC Ni-MH Rechargeable batteries is the best when using with ATC chargers. For other chargers that are not designed properly, it worsens the performance by overcharging, undercharging, or overheating of batteries.

Because of the internal active materials (fuels) in the chemical system of rechargeable batteries, the operating voltage varies among different type of batteries. For rechargeable batteries, the operating voltage is around 1.2Volt while alkaline batteries are 1.5 Volt. However, this does not affect the performance of the Ni-MH battery.

Rechargeable batteries can be recycled at any Rechargeable Battery Recycling location without any fee.

he factors should be considered:

A smart charger can detect the battery status and if the batteries are charged, it will stop charging automatically. A timed charger stops only when it has charged batteries for a specified period of time.

Rechargeable batteries can be recycled at any Rechargeable Battery Recycling location without any fee.

Typically, a blinking light indicates one of three events. The first one is bad contact. Check if the contacts of battery and charger are both clean. A cloth can be used to clean the contacts after unplugging. A pencil eraser is suggested for excessive dirt. Also check if the battery is fitted correctly. Otherwise, it may be a bad battery or a bad channel.
