In the past, you might have just NJ batteries without thinking about it. Now, you can use your batteriesrrMre intelligently, safely, efficiently, and without waste.

Nickel-metal hydride batteries include types that are the same size and shape as manganese or alkaline batteries, and can be used in a wide range of devices. However, a key point when using batteries together is that you should always use the same brand, type, and performance rating.
As shown in the chart below, certain silver-oxide batteries can be used with devices compatible with alkaline button batteries, while other silver-oxide batteries can be used with devices compatible with lithium batteries.
|Alkaline button batteries (1.5V)|
|Silver-oxide batteries (1.55V)|
* Some batteries may not be compatible with certain devices. Always read the operating manual.
Batteries contain chemical substances and so may be damaged by heat or humidity. Be sure to avoid storing batteries in high temperatures, high humidity, or direct sunlight.Such storage conditions would reduce the lifespan of the battery and may lead to ruptures and leakage.
If batteries have been removed from their packaging, store them in plastic or paper bags, ensuring that positive (+) and negative (‐) poles never come into contact. When storing batteries in pockets or bags, always keep them separately from keyrings, necklaces, or other metal objects to avoid short‐circuiting. (Never store batteries in metal containers either)
Store batteries out of reach of babies and small children. It is said that “92% of accidents where batteries are swallowed involve children aged three or younger.”
Choose the same manufacturer as your batteries. Choose between "Ni‐Cd/nickel‐metal hydride dual compatible", "Ni‐Cd only", or "nickel‐metal hydride only"; and between "AA only" or "AA/AAA dual compatible" according to how the batteries are to be used.
Think about "how many batteries of which size(s) you will need to charge at once," and whether you need features such as "charging complete displays" or "fast charging". If you plan to carry your charger around with you, choose a light, compact model. It is also useful if the power plug can be folded away.
The key point when charging batteries together is that you should always charge the same performance batteries (brand, type, capacity).
If you recharge your batteries the wrong way around, they become unusable or even generate heat and rupture.
Charging times will vary with different chargers. Check the charger's operating manual. Overcharging batteries will reduce their lifespan.
Use a wall socket away from any televisions or radios. This will avoid the risk of interference.
Occasionally wipe the positive (+) and negative (‐) contacts with a dry cloth to remove any dirt. If the contacts are dirty, it may not be possible to charge the batteries.
Whether they are Ni‐Cd batteries, nickel‐metal hydride batteries, or lithium‐ion batteries, all rechargeable batteries can be recycled. Take them to your local electronics store. These batteries come under the Law for the Promotion of Utilization of Recycled Resources in Japan.
Failure to do so may result in heat generation and ruptures if batteries with remaining charge come into contact with other metals.Always take the time to insulate your batteries before disposal. Never "throw," "dismantle," or "crush" batteries.
This display means that "if you start using the battery before this date, it will operate with a sufficient level of performance." It does not mean that the battery will not work after this date.
There are no legal stipulations for the disposal of dry batteries, but always follow your local rules for disposal.
This display means that "if you start using the battery before this date, it will operate with a sufficient level of performance. " It does not mean that the battery will not work after this date.
This means that "the battery contains absolutely no mercury."
These displays designate a recommended use‐by date of June 2017. The displays can be found on the body of the battery (base or side), or on the smallest item of packaging (e.g. on the mounting for button batteries or lithium batteries).
