Energizer e2 lithium batteries are available in AA size, in packs of 2.
They are ideal for use in applications such as security PIRs, where a long standby
life is required.
In a radio frequency PIR or security device such as the X10 secure PIR
or the X10 wireless window/door contact, you can expect a life of 50 months at 10 transmissions per day,
or 45 months at 50 transmissions per day
In more conventional applications, such as high drain uses eg digital cameras,
the Energizer e2 litium AA battery last five times longer than ordinary alkaline batteries.
Energizer e2 lithium AA batteries weigh about one-third
less than ordinary batteries and operate well in extremely hot and cold
temperatures, from -40 to + 60° C.
