A battery turned warm in my pocket. Is this normal? 
No, batteries should not become warm when not in use. We print a caution on our packaging 
warning consumers not to carry or store batteries loose in your pocket or purse. They can be 
shorted by contact with metal objects and leak or rupture and cause personal injury. 
 
Are batteries affected by temperature? 
We recommend storing batteries at room temperature in a dry environment. Extreme heat or cold 
reduces battery performance. You’ll want to avoid putting battery-powered devices in very warm 
places. In addition, refrigeration is not necessary or recommended. 
 
Can alkaline batteries be recharged? 
Only batteries that are specifically labeled “rechargeable” should be recharged. Any attempt to 
recharge a non-rechargeable battery could result in rupture or leakage. We recommend that you 
use NiMH Duracell rechargeables. Paired with one of our different chargers, they can be 
recharged hundreds of times. 
 
Can I charge other brands’ rechargeable batteries in a Duracell charger? 
Yes, Duracell chargers will charge other NiMH AA or AAA batteries. However, Duracell cannot 
guarantee the quality, safety, or performance of other battery brands, so using Duracell 
rechargeable batteries is recommended. 
 
Can I mix old and new batteries? 
Do not mix old and new batteries. Doing so will reduce overall performance and may cause 
battery leakage or rupture. We recommend replacing all batteries within a device. 
 
Can I recharge any battery?  
You can only recharge a battery if it’s specifically marked “rechargeable.” Recharging a non-
rechargeable battery may cause it to rupture or leak and may cause personal injury. 
 
Can I take a battery apart? 
No. Do not dismantle batteries. When a battery is dismantled, contact with the components can 
be harmful and may cause personal injury or fire. 
 
Can I use batteries underwater or in other vacuum conditions? 
No, Duracell batteries are not designed to be used underwater or in vacuum conditions. The cells 
are designed to be used under normal atmospheric conditions and in fairly constant temperatures 
(approximately 21 °C/70 °F). 
 
Do all batteries last the same amount of time?

No, different batteries provide different lengths of life and power output depending on the type and amount of chemicals used to compose them. Think of it like cooking a meal: Using different ingredients and amounts make the meal taste different. Do Duracell rechargeable battery chargers shut off when charging is complete? Duracell chargers switch to a trickle charge when the normal charge is complete. You should unplug your charger when charging is complete or when it is not in use.

In the unlikely event that a battery is wet or covered with a white powdery substance, limit your handling of the battery. Only handle the battery as required for proper removal and disposal and immediately wash any exposed body surfaces and clothing with soap and water. If contact with the eyes occurs, immediately flush the eyes with running water for at least 15 minutes and then seek immediate medical assistance. My child likes to play with batteries.

Duracell pioneered the Alkaline Manganese Dioxide electrochemical system nearly 40 years ago. In the 1960s, this battery system rapidly became the popular choice of designers in the everwidening field of consumer electronics. Alkaline or Alkaline Manganese Dioxide cells have many advantages over zinc-carbon cells including up to ten times the ampere-hour capacity at high and continuous drain conditions.
