Question 1

Are these batteries safe to use in my smoke or carbon monoxide alarm?**

Accepted Answer

Yes, absolutely. This is one of their most popular and praised uses. Their low self-discharge rate and stable voltage output make them a reliable and safe choice for critical safety devices. Many reviewers on platforms like Reddit specifically mention using them for this purpose with great peace of mind.

Question 2

Do I need a special charger for these batteries?**

Accepted Answer

Yes. These are Lithium-ion (Li-ion) batteries and require a charger designed for Li-ion chemistry. They will **not** charge in a standard NiMH rechargeable battery charger. We recommend using the EBL Li-ion charger or another charger explicitly rated for 9.6V Li-ion cells.

Question 3

I use 9V batteries for my guitar pedals. Are these a good fit?**

Accepted Answer

It depends on your pedal's power draw. These batteries excel in low-drain devices. For a single, low-power pedal, they may work well. However, for multiple pedals or high-drain units, some users on music forums report shorter run times compared to high-capacity NiMH batteries. For consistent, high-drain use, a 9.6V NiMH battery with a higher mAh rating (e.g., 280mAh+) might be a better performer.

Question 4

I've read some comments about fit issues. Will these fit my device?**

Accepted Answer

They are designed to standard 9V dimensions. However, a small number of users have noted the terminals can be stiffer than some disposable batteries, making insertion into devices with very tight or rigid spring contacts slightly tricky. For most standard compartments (like in smoke alarms or toys), fit is not an issue.

Question 5

What's the main advantage of these over traditional rechargeable 9V batteries?**

Accepted Answer

The key advantage is their performance profile. Li-ion batteries like these hold their charge much longer when not in use (low self-discharge), making them ideal for devices like smoke alarms that need reliable power over months. Traditional NiMH rechargeables may lose charge faster on the shelf but can offer higher current output for very high-drain devices. It's about choosing the right tool for the job.
