Evolta Battery LR20EGM/2B (D Size)

Panasonic EVOLTA AA cells feature advanced Anti-Leak Protection that suppresses gas buildup when a battery is over-discharged or stored for a long period. Less pressure means less chance of structural failure and rupture, and protects your valuable devices from damage.

Our exclusive high-reactivity formula, including titanium additive and high-purity manganese dioxide, combine in EVOLTA AA batteries to generate extra voltage for power-hungry devices. We call it Extra Power Formula, and you can rely on it to deliver maximum current for far longer than comparable batteries.

If the density of the filling materials inside a battery is inconsistent, performance can suffer. The development of new materials has led to uniform, homogenized filling density which allows current to flow with greater consistency in EVOLTA AA batteries for superior performance.

In conventional batteries, contact resistance on the terminals can build up and cause the nickel layer to peel off and the battery to fail. Triple Tough Coating solves this with an iron/nickel-plated alloy on the positive and negative terminals that improves adhesion and reduces contact resistance. The result? Enhanced energy flow and longer life.
