1. When should I use Energizer_® MAX^® alkaline batteries?
   Energizer_® MAX^® is the perfect alkaline battery when you need power that lasts—and performance you can count on. A flashlight to lead the way. A smoke detector to alert you. Or simply a radio to play your favorite song over and over. But if you’re using high-tech, high-drain electronics, you may want to use Energizer_® High Tech Batteries.
   
   
2. What’s the difference between Energizer_® e^2® Titanium Technology_® and Energizer_® MAX^® alkaline batteries?
   Both Energizer products are standard alkaline-based chemical systems. However, Energizer_® e^2® Titanium Technology_® batteries are formulated differently than ordinary alkaline batteries. They have a proprietary titanium compound and advanced cell construction, allowing improved performance and providing longer-lasting power. Therefore, they are best suited for high-tech devices that consume a lot of power.
   
   
3. How long do Energizer_® MAX^® alkaline batteries last in the package?
   Energizer_® MAX^® has a shelf life of up to seven years in the package. Of course, they perform better in your clock than in your closet.
   
   
4. Should I store alkaline batteries in the refrigerator?
   Storing batteries in refrigerators or freezers is not required or recommended for batteries produced today. In fact, cold temperature storage can harm batteries. To maximize performance and shelf life, store batteries at normal room temperatures with moderate humidity levels.
   
   
5. How long do alkaline batteries last in a device?
   There are several factors that impact battery run time. The most critical is the rate at which a device consumes power. A high-drain device like a digital camera will deplete a battery much faster than a low-drain device like a clock. Other factors affecting overall battery performance are environmental conditions, device usage patterns (continuous or intermittent) and battery size/chemistry.
   
   
6. How should I dispose of alkaline batteries?
   It’s safe to drop them right in the household trash. In 1989, Energizer became the first company to remove all added mercury from alkaline batteries.
   
   
7. Are alkaline batteries considered hazardous waste?
   No. In the United States and many other countries, alkaline batteries are classified as common household waste. Great strides have been made to make alkaline batteries better for the environment and they’ve been manufactured free of added mercury since the mid 1990s. Classification details may vary and should be confirmed in each specific geographical location.
   
   
8. Is it a problem to mix batteries of different chemistries, brands or ages?
   Mixing battery types in a device is not recommended and can significantly increase the potential for leakage and reduced performance. The biggest problem is an imbalance in available energy between the installed batteries. So always practice smart battery care and replace used batteries with new, fresh batteries of the same brand—preferably Energizer.
   
   
9. Is it dangerous to carry loose batteries in a purse or pocket?
   Batteries can be short-circuited by metal items such as coins, keys, paper clips, etc. A battery that experiences a short circuit can become very hot, increasing the potential for leakage and personal injury.

10. What increases the potential for alkaline battery leakage?
    Typically, alkaline batteries will not leak under normal storage and usage conditions. However, the potential for leakage is significantly increased if batteries are subjected to charging, mixing of battery chemistries, mixing of fresh and used batteries, physical damage, extended exposure to high temperature or deep discharging. Alkaline battery leakage is extremely caustic and contact with bare skin should be avoided. In the event that battery leakage comes in contact with your skin, flush the area for 15 minutes with copious amounts of water.
    
    
11. Can alkaline batteries be charged in a NiMH or NiCd battery charger?
    Standard alkaline batteries are not designed to be recharged and should never be placed in any battery charger. Attempting to charge alkaline batteries will significantly increase the likelihood for leakage to occur. Rechargeable alkaline batteries made by other manufacturers may also leak if placed in a NiMH or NiCd charger and should only be recharged in a charger designed for that system. Of course, Energizer_® Rechargeable batteries have all the rechargeable power you’ll ever need.
    
    
12. Who invented alkaline batteries?
    Energizer scientist Lew Urry hand-built the first commercially viable alkaline battery in 1959. Today, you can check out his prototype cell at the Smithsonian Museum of Natural History.
    
    
13. Is there a guarantee on Energizer_® batteries?
    The Energizer_®/Eveready_® guarantee typically states: “We will repair or replace, at our option, any device damaged by these Energizer_® batteries. Guarantee void if batteries are charged by user or device.” Contact 1-800-383-7323. This guarantee may vary globally, so please check with your local Energizer office for details.
