Rayovac High Energy Vs Energizer Max: Which One Is A Better Series?

Alkaline batteries are hailed in households for their affordable pricing and better runtime. In this domain, a detailed Rayovac High Energy vs Energizer Max is overdue. Which one should you buy?

According to selling price data, Rayovac High Energy is the clear winner. But you must consider other factors such as performance, shelf life, durability, and reliability.

In this article, I have talked about all of those with enough data so that you can have a clear overview of the two alkaline battery series.

Performance and Runtime

Following the ANSI standards, the BatterySavers team conducted a test comparing the alkaline battery performance of several brands.

It included Rayovac, Energizer, Duracell, and Eveready. Among them, Rayovac outperformed other brands.

Regarding Rayovac vs Energizer, the difference is not that much. They used similar flashlights and D-size batteries from each mentioned brand.

In the end, Energizer lasted for 22 hours and 15 minutes whereas Rayovac lasted for a whopping 24 hours and 30 minutes.

Here, the clear winner is the Rayovac High Energy battery series but it is not the only criteria you should consider before choosing one finally.

Cell Composition

As all of the concerned models of batteries in this article are alkaline, their cell chemistry is the same too.

I have read the technical data sheet of AA, AAA, C, D, and 9V batteries from both series to confirm this statement.

The cells don’t use any harmful components such as mercury during production making them safe for everyday uses and the environment.


The overall weight of all batteries in the High Energy and Max series is slightly higher in the Energizer brand.

More weight typically means more capacity and longer runtime.

But the difference in their weight data is so minimal that it seems like other parts of the body that is not related to the capacity are responsible.

Operating Temperature

There is a standard range of the OT (operating temperature) for these batteries. Both brands follow that.

Nonetheless, there is a difference between them. High Energy batteries can operate from -30°C up to 55°C or -20° F to 130° F.

On the other hand, Max batteries can operate from -18°C up to 55°C or 0°F to 130°F.

You can notice that the upper limit of the range is the same. The lower limit doesn’t matter much because most of the applications don’t need that.

Still, if you have to run a device that has to operate under -18°C, you have to choose the Rayovac High Energy series.

Shelf Life

9V batteries from both brands can hold their voltage level for up to 5 years if you store them at 21°C.

And, for AA, AAA, C, and D size batteries, you can expect a shelf life of up to 10 years stored at 21°C.


I have read lots of customer reviews regarding High Energy and Max batteries. Most of them show positive feedback.

However, some of the customers are not happy with the runtime of these batteries. This problem can occur for various reasons.

If the electronic device gets faulty and leaks charge, it can drain the battery faster than expected.

Other complaints mention not getting the full count as listed on Amazon. For example, one customer got 11 batteries whereas he/she paid for 12.

So, those are not the faults of the manufacturer. You can trust both brands.

Both of them market their batteries with a no-leakage guarantee. For Energizer, you can expect no leaks for up to 2 years.

Rayovac promises no exact expiry date but you can expect something similar to Energizer.


Here, I’m going to list the batteries sold on Amazon, and compare the prices of the similar count.


  1. Rayovac High Energy AA Batteries (42 Count)
  2. Energizer Max AA Batteries, 44 Count

Here, Rayovac costs 0.66 per count, and Energizer costs 0.84 per count.


  1. Rayovac AAA Batteries 8-Pack
  2. Energizer AAA batteries, 8 Count

Here, Rayovac costs 0.68 per count, and Energizer costs 0.75 per count.


  1. Rayovac High Energy C Batteries (12 Pack)
  2. Energizer Max C Batteries, 12 Count

Here, Rayovac costs 1.56 per count, and Energizer costs 1.92 per count.


  1. Rayovac High Energy D Batteries, 12 Count
  2. Energizer Max D Cell Battery, 12 Count

Here, Rayovac costs 1.32 per count, and Energizer costs 1.63 per count.


  1. Rayovac High Energy 9V Batteries, 8 Count
  2. Energizer Max 9 Volt Battery, 8 Count

Here, Rayovac costs 2.11 per count, and Energizer costs 2.62 per count.

I think that you have got a clear picture here. Energizer Max batteries cost slightly higher than the Rayovac High Energy series.

So, the winner is again Rayovac.


I have seen no complaints regarding the durability of these batteries. Both Energizer and Rayovac use premium materials and cutting-edge technology to manufacture them.

So, these batteries don’t leak easily. The 9V batteries from both brands have steel jackets, and other types have plastic jackets.

The metal used to make the terminals are rust-proof in ideal conditions. Don’t keep them in contact with water, and you have nothing to worry about.


Unfortunately, there are no warranties regarding single-use AA, AAA, C, D, and 9V alkaline batteries.

Some eCommerce stores of physical shops have their own return policies. So, if there is any manufacturing fault, you can get a full refund or replacement.

Rayovac High Energy or Energizer Max: Which One to Choose?

Considering price, performance, and other parameters, I think that Rayovac has the upper hand over Energizer here.

Nevertheless, please don’t think that the statement is true for all other series of these brands.

I am only talking about High Energy and Energizer Max series here.

Declaring Rayovac as the winner doesn’t mean that choosing Energizer will be a bad choice.

As we are talking about two very popular and top brands in the industry, you can choose any of them without regretting them later.
