Bonai Rechargeable 9V Batteries 600mAh High Capacity 9V Rechargeable Batteries,(4 Pack) 9 Volt Lithium Batteries for Smoke Alarms Metal Detector etc - Long-Lasting & Economical

A lot of musicians will benefit from these batteries, since they can use them for wireless microphones as well as for guitar pedals like Reverb pedals. Despite possessing Duracell and Energizer rechargeable batteries, the LifePaks give them a run for their money in terms of.

In the case of these batteries, it is essential to understand that the voltage is, by design, LOWER than on a standard Alkaline (non-rechargeable) The problem is not a concern for many applications. To help me replace the batteries in my smoke and fire detectors, I was hoping to use these. Since AC power is used for the detector units, batteries last for a long time. It would be more convenient to use rechargeable batteries in this case, so that they could remain charged whenever the AC is turned on. The lower voltage, however, results in the detector beeping at you to inform you that the battery needs to be replaced. (Monitors the voltage of a battery to determine whether it needs to be replaced. ) As I said, I did not have any luck with these.

It is a known fact that people who are smart, and who are men, like interesting things that look cool. The woman will think this is a pointless review, and it will not appeal to her. It does not matter where they stand on aesthetics, females like practical, useful gadgets. The way electronics appear in my opinion is very important to me as an inventor and builder of electronics, stereo equipment, healing machines, and computer parts. It is one of my passions to make works of art with electrical devices, and I solder my own gadgets. The batteries in this machine are used in the Bob Beck healing machine. Batteries in this machine form part of the overall look of the machine, and they look seriously badass.

So, here are some photos of some devices I have built. They show how the batteries have been integrated into the design. Located on the left side of the display are these green and black Bonai 600 mAh batteries Li-ion batteries are by far the most visually appealing of all the batteries on the It doesn't get cooler than this. It looks amazing with the chrome and green writing on the black background. It is hoped that these will never be changed. It's hard for me to say how much quality testing I have done. four batteries I bought work and are able to A test score of 8 was obtained. Batteries that have sat on the shelf without being charged for almost a year should be 20 volts. In my experience, the rate of self discharge is extremely low The Starseed Deluxe.

It is a real pleasure to work with them. Its batteries are quick to charge and hold their charge for a long time. I use it in a medical device and got frustrated with the amount of batteries I was buying and throwing out. The best part is that they work with the charging base I previously purchased from EBL. In a strange turn of events, the EBL batteries I bought would not charge in their own charger, but these do.

This Bonai 9V battery pack replaced a regular 9V battery in my smoke detectors and an electronic keypad for a vault.

I am giving it two stars because it is LARGER than a regular 9V battery. Aside from the length and width, there is a depth as well. However, they do produce the required voltage, but being out of specs for size is a very big problem Several other customer reviews were negative, stating that Bonai 9v batteries were not compatible with smoke detectors and alarm systems. Since the batteries are too large, I discovered the contacts in the smoke detector/alarm could not make contact with the contacts on the batteries. You may be able to use these batteries in a device that does not have a 9V battery space requirement if you use them in a device that does not have that space requirement.

A few years ago, I used to use 3 or 4 NIMH LSD batteries in BlueTooth devices and they would last for about a year Based on how I used them, these Lithium batteries lasted for 3 months The Li-ion batteries that I have last from 6 to 12 months. I charge them rather than wait for them to die. The cost is a bit higher, but the quality is worth the extra investment. They are so much better than the best NIMH LSD batteries out there while also being more expensive. As of yet, I haven't had problems with them not returning my calls Using them now for over a year now, and so far they have performed well We have been using them for 1 year and they still work well.

I just bought another set, since they hold their charge for a long period of time and provide power all day long to my audio equipment, unlike another rechargeable brand. My only issue with these Bonai 9V batteries is they are thicker than the ones I bought a year ago and not all of my devices can use them, including Although the rating is the same, 9V 600mAh, the battery itself is thicker and thicker for no reason what so ever. The batteries I used are 9V NiCad standard and thicker than these. I'm not sure why this is the case. It would be a good idea to check your device first, or to buy a different brand of phone.

The batteries I use are great. I am very satisfied with their performance. They fit if they are in the right place. It seems these batteries fit a bit too snugly into my Boss guitar effects pedals. The EBL 9V batteries are about the same size and dimensions as a typical Alkaline 9V battery, so I bought them for those pedals. Bonai's products have worked out well for me in the past, but their 9 volt batteries could be a bit smaller to fit into most 9 volt batteries. It just doesn't fit in a lot of my devices as they're a bit thick.
