Recently re-branded from Energizer Ultra+, Energizer Max batteries are high performance long life alkaline batteries which are available in AA, AAA, C, D and 9V sizes. Featuring Ultra+ power seal technology these batteries will keep their power locked in for up to 10 years meaning long term periods of inactivity will not drain the battery and effect their performance when needed.

The high capacity and long life of Energizer Max batteries makes these cells ideal for powering high drain devices which are not in constant use such as torches, toys, clocks and the 9V Max battery is great for smoke alarms.
