Why Parents Should Switch to 1.5V AA Lithium-ion Batteries for Kids’ Toys

Jan 06, 2024 | XTAR

In the world of today’s kids, where playtime is adorned with electric toys. The constant influx of new toys that dazzle, beep, and whirl with excitement brings joy to our little ones. These types of electronic toys typically require powerful batteries to drive them, so choosing the right batteries is crucial.

But parents typically are most concerned about three aspects: safety, cost, and convenience. In our pursuit of solutions, we turn our focus to AA 1.5V rechargeable lithium-ion batteries. Join us in uncovering the potential of 1.5V AA rechargeable lithium-ion batteries to see if they can address the concerns of parents.

Safety First: Prioritize Kids Safety When Using Battery

In the world of parenting, safety is the cornerstone of all activities. For kids’ toys, it is imperative to ensure high safety standards in all aspects, including batteries.

Harmless to kids: Presently, the majority of batteries available employ eco-friendly and non-toxic casing materials. However, if the casing of batteries containing heavy metals is damaged, those heavy metals can easily enter a kids’ body through the mouth. This situation can lead to metal poisoning or other health issues. Moreover, small button batteries commonly found in toys are easily ingested accidentally by kids, and if that happens, the consequences can be severe. Rechargeable 1.5V lithium-ion batteries do not pose these issues. They do not contain harmful substances such as mercury, cadmium, and lead, and also come with secure battery compartment and child-resistant designs. These features effectively ensure the safety of kids.

Away from Dangers: Batteries work in circuits, so many parents tend to consider more deeply. Battery leakage can damage toys and create trouble for kids. Additionally, overheating and short circuits in batteries may lead to burns or other dangers, such as explosions. In contrast, 1.5V rechargeable lithium-ion batteries are equipped with multiple protection mechanisms such as temperature protection and short circuit protection. These integrated mechanisms act as vigilant sentinels, preventing the occurrence of abnormal situations and ensuring the safety of kids.

Choose Wisely: Long-Term Battery Savings Solutions

For parents, financial considerations often weigh heavily. Certain expenditures have a tendency to rise over time, and this reality is also reflected in the demands for batteries in kids’ toys.

The most common batteries for kids‘ toys are disposable ones, which might seem cost-effective initially. However, the seemingly modest upfront cost accumulates over time, making it less economical. Rechargeable batteries offer a more sustainable solution, but the initial investment in both the batteries and chargers can be a deterrent for many parents. In response to this concern, it might be helpful to draw conclusions after reviewing the table below.

AA dry battery




2500mAh 1.2V AA Ni-MH




2500mAh 1.5V AA Lithium-ion




* Note: Prices are based on current market conditions. AA disposable dry batteries typically have a capacity of no more than 1500mAh.

In the long term, opting rechargeable AA and AAA batteries is the most affordable choice. With the purchase of just one charger (basic battery chargers are available on the market for as low as around $15), the economic burden of frequent battery purchases can be eliminated. Additionally, the capacity of rechargeable Ni-MH batteries tends to diminish over time, and they have a shorter cycle life. The capacity of rechargeable Lithium-ion batteries remains more stable during use, and their cycle life is significantly longer. In the world of parenting where every penny counts, we can make a choice based on our own needs and financial conditions.

Effortless Playtime: Dive into the Convenience of Battery

Many parents need to balance work and household chores while promptly addressing their kids’ needs, so convenience is a necessity for busy parents. Batteries in kids’ toys are no exception.

Uninterrupted Playtime: Imagine this: kids are happily interacting with their electric dolls, only to have the play interrupted due to battery depletion. Or perhaps, they’ve just started playing with a remote-controlled car, and it gradually comes to a halt because of low power. In these situations, parents have to pause their tasks to replace the batteries. Does this happen with 1.5V rechargeable lithium-ion batteries? The answer is no. A recent Instagram post featuring a Nintendo’s DMG Game Boy showcased the endurance of a 1.5V AA rechargeable lithium-ion battery, powering the game controller for an astounding 29 hours. This surprised him and he thought it was a great choice to go with this battery.

Moreover, in recent years, some well-known brands in the market such as XTAR and Deleepow have successfully developed the rechargeable lithium-ion batteries with low power reminder. It means saying goodbye to the sudden loss of power in toys, ensuring a more prolonged and reliable usage experience.

Reduce Waiting Time: If AA rechargeable batteries are used in kids’ toys, and there are no spare batteries at home, the charging time is also a crucial consideration. Waiting for Ni-MH batteries to charge for over 10 hours is not an ideal scenario for parents. The emergence of 1.5V rechargeable lithium-ion batteries has solved the problem of long charging times. They can be fully charged using a professional charger in a remarkably short period, typically within 2-3 hours. No more grappling with your kid’s impatience during prolonged charging waits—instead, meet their play needs promptly.

Smooth Gaming Experience: The inconsistent performance of batteries can disrupt kids’ gaming experiences and they often turn to their parents for immediate assistance in such scenarios. However, recent experimental results on YouTube might alleviate parents’ concerns. The experimenter meticulously tested both 1.5V rechargeable lithium-ion batteries and 1.2V rechargeable Ni-MH batteries in a LEGO set, observing the 42099 X-Treme Off-roader navigating between obstacles. The results unveiled that, after running continuously for two hours, the rechargeable lithium-ion battery displayed a significantly faster speed, highlighting its consistent ability to maintain an excellent voltage output level. This characteristic provides enhanced support for kids’ entertainment activities.


Through the explanation in the previous content, we have come to recognize the significant benefits that 1.5V AA rechargeable batteries can bring to the field of kids toys. If there is a need to purchase batteries for the toys at home, consider abandoning traditional batteries and give 1.5V AA rechargeable lithium-ion batteries a try!
