Battery Life on Babysense Baby Monitors (11 Answers)

The Babysense series of baby monitors have been popular for years.

They are one of the most reliable and affordable brands, but some models have longer battery life than others.

If you want to get the most out of your monitor, it’s important that you know which ones have the longest battery life and can last all night.

In this article I will talk about the battery life of Babysense baby monitors and what to expect from which models.

Here’s the Battery Life on Babysense Baby Monitors:

The battery life of the Babysense Baby Monitor is approximately 20 hours in Eco mode and 12 hours in regular mode. For the split-screen V43 model, you should expect the battery life to be cut in half (10/6 hours).

Let’s look at the battery life on all Babysense models:

Model Battery life (Eco mode) Battery life (Regular mode)
Babysense True Sleep 20 hours 12 hours
Babysense Split Screen S2 20 hours 12 hours
Babysense Split Screen V43 10 hours 6 hours
Babysense Baby monitor S2 20 hours 12 hours
Babysense 7 6 months

What Babysense Baby Monitors Have the Longest Battery Life?

The longest-lasting baby monitor is the Babysense True Sleep and the V43 model.

These models use a rechargeable 400 mAh lithium battery, which means you don’t need to worry about changing the batteries as often.

The batteries will last longer if you charge them before they reach 0% battery left.

You will have a red indicator on the back of the device (check the Babysense 7 back, for instance) that shows you when its time to replace or recharge the batteries.

How Long Do Batteries Typically Last on Baby Monitors?

You can expect most baby monitor brands to provide lithium batteries with 4000 mAh. You also find these batteries in many other home appliances such as:

  • cellphones
  • small power tools

Batteries for baby monitors should typically be replaced within two-three years time.

After this time period, they tend to lose their charge very quickly and become more difficult to recharge.

However, some batteries may last longer than others depending on how often they are used and if they are stored in ideal conditions (a cool place away from direct sunlight).

These are the batteries used in Babysense monitors:

Model Battery type
Babysense True Sleep 4000 mAh lithium
Babysense Split Screen S2 4000 mAh lithium
Babysense Split Screen V43 2100 mAh lithium
Babysense Baby monitor S2 4000 mAh lithium
Babysense 7 4 x AA batteries

Are There Any Ways to Prolong the Battery Life?

It may be tempting to purchase a new monitor because you don’t want to deal with the hassle of replacing batteries. However, there are ways to prolong the life of your baby monitor battery.

You can preserve battery on the units by using the “eco mode”.

This will then down the screen light and prolong the battery life.

The other way is to keep good battery charging habits:

  • Always charge then unit before it reaches <10%
  • Always charge it up to at least 80%
  • Charge it for at least 7 hours on the first charge. 

How Do I Know If My Babysense Baby Monitor Is Fully Charged?

There is a battery indicator on the unit that will show you once the unit is fully charged.

Look for the battery icon that you will recognize from cell phones and other devices. It will show you now much power you have left on the device and when it’s fully charged.

Can Babysense Baby Monitors Work While Plugged In?

The Babysense baby monitor is designed to be used both as a portable unit and a static one.

The static option allows you to plug it into a wall outlet and use it as a standard baby monitor away from interference from WiFi or cellular signals.

How Long Does It Take to Charge Babysense Baby Monitors?

The charging time is approximately 1.5- 4 hours, depending on the size of the battery.

The battery life is quite good, so you don’t have to worry about losing signal when your baby is asleep or not moving around much in the crib.

For example, if your device is completely dead and needs a full charge, it may take up to 4 hours to fully charge it. If your device is only partially charged (for example, at 50%) then it will take less time (around 1-2 hours).

Can You Replace the Batteries on Babysense Baby Monitors?

Yes, you can replace the batteries on your Babysense baby monitor.

To do this follow these steps:

  • Remove the battery compartment cover on the back of the monitor and replace with new batteries.
  • Slide the detector off and replace it with a new one if needed.
  • Then, turn on the monitor and test it out to make sure it works properly.

When Should You Replace the Batteries?

If you notice any issues with your Babysense monitor, such as it going off or not receiving a signal, then you should check the batteries first thing.

This is especially important if you’ve just installed new ones or are using a new device for the first time.

You should also check the batteries when they shut off at around 20-30% left.

How Much Do Extra Batteries Cost for Babysense Baby Monitors?

If you’re running low on batteries, don’t worry! You can always order more from the Babysense website or Amazon.

Packs of two AA batteries are $3.99 in most stores.

This is for the Babysense 7 model.

The other models have built-in batteries are we don’t belive you can exchange for new ones:

  • Babysense True Sleep
  • Babysense Split Screen S2
  • Babysense Split Screen V43
  • Babysense Baby monitor S2

We haven’t been able to find replacement batteries for sale at the Babysense store or anywhere else, for that matter. So, it’s fair to assume that your baby monitor from Babysense is useless once the batteries start to wear off.

Do Babysense Baby Monitors Always Beep When the Battery Is Low?

Babysense monitors do always beep when the battery is low. Some models will only beep when the battery is really low and needs to be charged ASAP.

Two different types of batteries are used in these devices: alkaline and lithium-ion cells (which are also used in mobile phones).
