Although nowadays, the utilization of 9V batteries in portable electronics has declined, you can still find a variety of household devices that use these cells.

As you can see, the lower self-discharge feature of the Max-E battery helps it be conducive to a large number of applications. Basically, anywhere feel free to use an alkaline battery, use Max E batteries – and use them up to 1000 times.

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

Many of us have often heard the “warnings” with regards to the use of rechargeables in smoke detectors due to the problem with self-discharge from standard rechargeables. Basically we would agree that a standard rechargeable battery really should not be used for a smoke detector, etc. we would certainly advocate the use of the low-self discharge 9V cell — because the batteries maintain 85% of their power in a year.  Smoke detector batteries are supposed to be changed every Half a year – well within the capabilities of a Max E 9V cell.

Finally, due to the shift away from the use of 9V cells in electrical appliances and many times it really is hard to find a battery charger that also accomodates the 9V battery.  The Ansmann Zerowatt Powerline 5 Battery Charger does support  the charging of one 9V cell and causes it to be a total charger for all your household battery needs.
