Experience long-lasting power and reliability with Energizer Max Alkaline Battery which is perfect for long-term use. With a leak-proof guarantee and high-performance capabilities, it ensures a steady power output. Energizer Max is trusted for door locks with its wide availability and boasting shelf life.
One of the best features of the Energizer Max battery is there is almost no leakage. When you put batteries on your smart lock, one of the primary concerns is battery leakage. The battery leakage can damage your lock. Energizer provides no leaks guarantee for up to 2 years of full use which is a big relief.
This is a popular battery brand and you will find it in almost all the shops near you. However, ordering from Amazon would be best as you can take AA and AAA battery combo. Also, the 10 years of shelf life makes it easier to stockpile them.
Keeping the extra battery is important because a battery can be dead anytime. And you don’t want to get stuck at home just because you can’t lock the door due to the lack of batteries.
Energizer batteries have the ability to maintain a steady power output throughout their lifespan.
Also, this battery claims to be the first battery brand in the world with zero mercury content. So, it is safe for your body as well as the environment. If you are using a smart lock, you can pair it up with a good smart lock home assistant.
However, there are certain drawbacks you may face with this particular battery. After using it for 2 years on your door lock, there’s a chance of leaking.
Your lock’s user manual has a mentioned interval for possible battery replacement time. So, if your door lock consumes less power and the battery lasts more than 2 years, replace the battery after that.
Another drawback is, as a non-rechargeable alkaline battery, it will get weaker as time passes.
Duracell Coppertop Alkaline Battery
Overall Best Battery for Door Locks:
Pros:
- Longer shelf life
- Reliable brand name
- Wide availability
- Constant and reliable performance
- Power Boost™ technology makes it long-lasting
Cons:
- Leaks only after using it for 1 year continuously.
- Expensive
Here comes one of the leading brands in the battery industry. The popularity of Duracell is a solid certification of its performance. So, there’s nothing new to say. The overall best battery for door locks. With its longer shelf life, trusted brand name, and constant performance, Duracell is a popular choice.
Duracell is even more well-known compared to the Energizer batteries. It also has more market share than Energizer.
Duracell is also well known for lasting longer than any other battery on the market. Their patented Power Boost™ technology makes sure of that. This technology is not available in Energizer or any other battery brands.
The Duracell Coppertop has 12 years of shelf-life which is higher than the Energizer batteries. You can buy them in bulk and never have to suffer from running out of batteries.
Duracell is one of the best batteries for your door lock due to its power reliability. It will provide constant power for a smooth lock operation.
However, there is one major drawback of Duracell that makes it less reliable than Energizer. It starts leaking after only 1 year of continuous use. In some door locks, the battery runs for more than 1 year. In that case, even if your door lock doesn’t need a new battery, you have to replace it after 1 year.
Usually, smart door locks drain more battery power than regular electronic door locks. And the smart door locks are more secure as well. But if you have a regular electronic door lock, the battery may last more than 1 year. And then you should replace the battery and give a regular checkup.
Here’s a tip. After using 1 year in your doorbell, don’t throw it away. You can use the battery in devices that don’t have continuous use, such as toys. And later you can remove the batteries so it doesn’t leak on the devices.
Here’s an interesting video on the leakage test of Duracell and Energizer alkaline batteries.

Buying Guide For Batteries For Door Locks
While buying batteries for door locks, there are a few things that you have to keep in mind.
Battery Type:
There are different types of batteries in the market, including rechargeable, non-rechargeable, alkaline, and lithium-ion.
Most door lock manufacturers recommend using alkaline batteries in the lock. Rechargeable batteries are not suitable because, unlike alkaline batteries, you won’t get any warning before the battery is completely dead.
And you will end up having a locked door before getting a chance to replace the battery. Depending on the door lock type, you may have to use either AAA or AA batteries.
Battery Leak-Prooffness:
Batteries don’t usually leak when they are outside of the device., but when the batteries are inside a device for a long time, they start to leak.

Battery Life:
Look for batteries with a long lifespan. Research which batteries last longer and provide consistent power. Some manufacturers provide estimated battery life, which can give you an idea of how often you’ll need to replace them.
