We also have an analysis of the risk that batteries pose and how you can choose between AC powered vs. battery-powered baby monitor options.

In 2014, the U.S. Consumer Product Safety Commission (CPSC) recalled over 800,000 units of baby monitor batteries manufactured by 15 baby monitor brands such as Samsung and Summer Infant. The hazard that was reported by thousands of parents involved Summer Infant batteries overheating and rupturing, posing a burn hazard to infants.

At Safer For Baby, we have closely monitored almost all the baby monitor brands and have always warned parents against any baby monitor with parts or accessories that may put your baby at risk. Aside from burn hazards, some baby monitor batteries are so bad that it can barely hold a charge. One of the best-selling audio baby monitors has received thousands of complaints because the battery life is barely 2 hours. We embarked on a research mission to find a baby monitor batteries that you can truly rely on, especially if your baby monitor is powered by batteries only with no option of AC power. Before we get started, let’s review some of the basic information on baby monitor batteries.

A number of baby monitors are powered by batteries while others can be powered by both batteries and AC. Several security cameras that can be turned into a baby monitor such as Arlo or Nest Cam are principally powered by AC. Arlo actually advice is that you should only rely on batteries for a short period of time. This is one of the differences between baby monitors and security cameras. Security cameras are designed to rely on AC but surprisingly, some of the latest models such as Arlo Pro has the longest battery life that can go for up to 6 months!

Here are the basics:

What is a baby monitor battery life?

So, what is a baby monitor battery life? Rechargeable baby monitor batteries last for 6 to 20 hours depending on the brand and the type of battery. This is the number of hours the baby monitor can use a fully charged battery until it is fully drained. Some brands such as VTech have very small battery life while others such as Willcare have longer battery life.

We analyzed 43 baby monitor brands and even though we found a strong correlation between the battery life and the brand, the type of battery also had a big impact on how long the battery lasts. For example, the inexpensive audio baby monitors by VTech are rated for up to 8 hours of battery life while Willpower’s similar audio baby monitor lasts for up to 20 hours. Let’s look at some of the main brands in detail starting with VTech.

VTech Baby Monitor Battery

The VTech baby monitor battery life ranges from a few minutes to just over 3 hours. Most users see their battery life decline shortly after using it for three months. This short battery life has been known as the biggest disadvantage of using VTech audio baby monitors.

Most VTech baby monitors use Alkaline AAA batteries to power the parent unit in most of its sound-only models such as VTech DM221, VTech DM1211, and VTech DM1111. VTech is one of the top baby monitor brands that also manufacture toys and baby products. In fact, three of VTech’s audio brands are currently among the top 10 best-selling brands on Amazon as of this article publication (September 15, 2019).

Despite all the problems with VTech DM111 batteries, it is the second best-selling baby monitor mostly because it is one of the cheapest baby monitors that sell for under $20

The picture below shows the back of VTech DM112 monitor where you can open to replace the DM112 and DM112-2 batteries.

From our estimates, VTech ships about 18,000 units to parents every month and it is surprising that the VTech battery life problems have persisted for so long. VTech baby monitors are notorious for burning through AAA Alkaline batteries at an alarming rate. Below is an example of Alkaline AAA batteries:

Their batteries drain very quickly and Parents have complained that even monitors sold with rechargeable batteries built in can drain quickly. The table below has an analysis of how long you should expect your VTech baby monitor batteries to last. If your VTech baby monitor battery is not charging or lighting red, it may not be charging and you should reach out to VTech customer care. We have a separate post on what you should know and specifically how you should deal with VTech customer service.

Despite VTech DM221 and 221-2 models making it to BMC’s top audio baby monitors list, we had great reservations on these models. Parents have had to depend on AC power to continuously charge the parent units as it barely holds a charge for more than 30 minutes. This is despite VTech promising and actually highlighting on their marketing materials that the batteries can last for up to 18 hours. See the quote below from their marketing materials.

“Rechargeable batteries provide the parent unit with up to 18 hours of monitoring time on a single charge, or use two AAA batteries (not included)”

From VTech marketing materials

In most VTech baby monitors, the battery icon flashes a light when the battery life. They also claim that it can be fully charged within 30 minutes. Unless you do not have access to AC power, you should plan on relying on AC Power to power VTech baby monitors as their battery life is very short.

For most of the VTech baby monitors that are powered by AAA Alkaline batteries, you should know that these batteries are sold separately. Alkaline batteries are not the best among all the array of batteries we reviewed. In addition, VTech only offers a 3-month warranty which basically means that it won’t be easy to get a replacement battery for your VTech baby monitor.
