Which lasts longer Duracell or Energizer?
Several tests were conducted on these batteries while they were used in clocks. The results showed that Energizer AA batteries lasted almost three times longer than Duracell batteries. However, when used in flashlights, Energizer batteries lasted up to 3 hours or so whereas the Duracell batteries lasted up to 6 hours!
Do batteries expire if not used?
Most unused alkaline batteries will last between five and 10 years, while Ni-MH batteries have a shelf life of three to five years of non-use. Lithium-ion batteries, which power devices like cell phones, have a low self-discharge rate and could keep a partial charge for up to four years before being depleted.
Do alkaline batteries degrade over time?
Batteries gradually lose power through what is called self discharge. So when you are given a lifespan for batteries is means that some threshold of capacity remains after that lifespan. Normally the lifespan of alkaline primary (e.g. single use, no rechargeable) cells is considered to be 5–10 years.

Why do Duracell batteries leak so much?
After normal use, a battery should not leak. The cell is strong enough to withstand built up gases inside. Leakage happens when a battery is left in a device for too long, especially when it’s not used. As that device is left unused, it still periodically ‘checks’ for the remaining power.
Do Duracell batteries leak more than Energizer?
Energizer contributes to the Rechargeable Battery Recycling Corporation. In addition, they’ve both stopped using mercury in battery manufacturing. However, Energizer batteries have been known to leak faster than Duracell alkaline batteries after expiry.
Do batteries last longer in the freezer?
In short: no. While cold environments help maintain battery life, refrigerators and freezers are not safe to put batteries in. The moist environment will cause condensation on the batteries. This in turn will lead to rust or other damage.
What does the date on a Duracell battery mean?
The expiration date is usually the date past which the manufacturer will not guarantee that full life is left. It is probably a conservative date, so most batteries will have a full life after that time. Better batteries will show a later expiration date.
How do you store Duracell batteries?
Store batteries in a dry environment at room temperature or slightly cooler. Avoid storing batteries in extreme temperatures that range from hot to below freezing. Storing batteries in cooler temperatures might lengthen the life of some batteries, but this isn’t necessary for many household batteries.
Which is better lithium or alkaline batteries?
Lithium batteries, as opposed to alkaline, are capable of giving off a strong energy surge after a long period of low discharge. This makes them ideal for fire alarms. Alkaline batteries provide good, long-term power, but they lose strength over time.
