As we discussed, the low self-discharge feature of the Max-E battery makes it conducive to a large number of applications. Basically, anywhere you can use an alkaline battery, you can use a Max e battery - and use it up to 1000 times.

While this in itself is a tremendous savings, the real power of Max E technology is shown in the Ansmann 9V battery.  First, the 9V Max E cell has the same capacity as the standard rechargeable - 250 mah.  This makes the cell available for both high-drain and low drain applications. Max-E 9V's can be used in high power  RC cars, metal detectors, wireless mics, walkie-talkies, paintball guns, tens units and other medical devices, personal fans, as well as low-drain devices including smoke detectors, carbon monoxide detectors, as well as guitar effects pedals, and audio visual equipment.

Many of us have heard the "warnings" concerning the use of rechargeables in smoke detectors due to the problem with self-discharge from standard rechargeables. While we would agree that a standard rechargeable battery should not be used for a smoke detector, etc. we would certainly advocate the use of the low-self discharge 9V cell -- as these batteries maintain 85% of their power in a year.  Smoke detector batteries are supposed to be changed every 6 months - well within the capabilities of a Max E 9V cell.

Finally because of the shift away from the use of 9V cells in electrical appliances, many times it is hard to find a battery charger that also accomodates the 9V battery.  The Ansmann Zerowatt Powerline 5 Battery Charger does allow for  the charging on one 9V cell and makes it a complete charger for ALL of your household battery needs.
