So fa,r so good - my new review

I charged all rhe batter but have not used them. I have an electric door lock that uses this size battery and I hate buying disposable batteries. Charges fairly quickly and easy storage.

Pros
  • The batteries are easily swappable, which is ideal for devices that require constant use
Cons
  • The batteries may experience internal shorts due to overcharging

Works okay but not very well made docking station.

Seems to charge okay and batteries are ok. My issue is that it’s really difficult to know if the batteries are seated in the charger correctly. The plugs aren’t lined up correctly so they are partially covered by the plastic housing. Charging takes longer than most of the aaa/aa chargers I have.

Pros
  • The charger has an LED display that shows you the current charging status of each battery
Cons
  • The batteries may suffer from voltage drops, contributing to short battery life

You'll need a USB port to plug the charger into.

I'm old enough to remember when rechargeable batteries were newer tech. They weren't terribly reliable and ran out quickly.To be fair, I've only used one battery until empty, and I'm extremely impressed! I have a TENS unit with a setting that uses a lot of power. A regular 9v battery would last an hour or two, and have to rest before I could use it some more.I put a bettery in my TENS unit last night and it lasted HOURS! With this being a 5 pack, I could easily go a full day if needed. So first

Pros
  • The batteries have a low self-discharge rate, so they retain their charge even when not in use
Cons
  • The charger may not come with all necessary charging cords, causing inconvenience

Contrary to negative reviews, mine works fine.

I purchased this in August 2019. I use the batteries for smoke detectors throughout my house, alarm clock power supply backups, and a guitar distortion pedal. The batteries have been reliable and the charger works just fine. Some reviews discuss measuring the battery terminal voltage and how it's not 9V. Firstly, measuring battery terminal voltage when it's under load is more meaningful. Secondly, complaints about it not being 9V betrays an ignorance of the different battery chemistries. It's…

Pros
  • Electronics
Cons
  • The charger and the batteries don't provide enough power, making them unsuitable for certain devices

Alternately flashing red and green LED's

Works good. Regarding questions and complaints that the LED's are alternately flashing red and green, and the batteries don't charge: check that your USB charging source can deliver at least 2 amps of current. I had this problem, until I noticed that my USB adapter was only rated for 0.5 A. After I substituted an adapter of 5 A capacity, no more problem.

Pros
  • Comes with a battery tester, so you can see the level of charge remaining
Cons
  • The 5-bay charger may be too large for some users' needs, making it impractical

Cheaper than buying them all the time!

These batteries are perfect for my transmitter packs when performing. Plenty of power to play an entire night. Previously I was buying new batteries for every show. Now I just yank them off the charger and away I go! Batteries for all my packs and a spare to boot!

Pros
  • I really like the charging station battery is yet to be fully tested. Good so far.
Cons
  • The charging time takes longer than expected, making it a hassle to charge the batteries

Product still being reviewed, good customer service.

I am a musician and I ordered these for my guitar and my wireless mic. The set up on these is very easy. They charge fairly quickly. I thought they would be perfect to use a fresh battery for each gig so I could save money on regular 9V batteries. I've used them 6 times and 3 of those times they stopped working in the middle of my gig. They were fully charged when I put them in the guitar/mic. When they stop, there is no warning. The instrument or mic just stops working altogether. I am very…

Pros
  • Simple to use, batteries are ready for use. Works great on my TENS machine. Can charge them in car.
Cons
  • The batteries only have a capacity of 600mAh, which is quite low compared to others

Does not come with wall plug & car charger

To clarify for other potential buyers, this item does NOT come with a wall charger or car charger. Of course the USB end of the provided cable could be plugged into a USB wall charger or USB car charger if you already have one. The charger only comes with the batteries, the charger and a USB charging cable.

Pros
  • Battery do not la
Cons
  • The capacitors in the batteries don't last long and can cause the batteries to die quickly

Best rechargeable batteries I've ever used

I've been using EBL batteries for the last 3 years and have never had a problem. I'm a bass player in a band, and my instrument has active pickups that require 9v batteries. I use the EBL's and they hold their charge. I also use the EBL 2800 mAh AA batteries in my wireless bass setup. I can play a full gig as well as a rehearsal with 2 AA batteries, and they still have more use left in them. They're a great product.

Pros
  • Comes with a warranty, so you can feel confident in your purchase
Cons
  • The batteries may become loose inside electronic devices and cause problems

may not be ecologicaly worth it

unbelievalbly long charge time.Is it better to buy throwaway batteries or spend the money on electricity? Thanks for attention.

Pros
  • Unique USB design: USB Input, connect the charger to power, 2A input suggested, more convenient, worldwide usage.
Cons
  • The charger's LED lights are too bright and can be a nuisance

Not exactly the same size as a regular 9v

They are not exactly the same size as regular non rechargeable 9v batteries, and therefore do not work in the device I bought them for (a wireless in ear monitor body pack) they don't make contact with the terminals inside the unit due to the slightly odd size of the battery.

Pros
  • Rechargeable batteries are more reliable than disposable batteries
Cons
  • The batteries may cause the electronic devices to heat up more than with regular alkaline batteries

Great product! - my new review

These are great! They have saved me a ton of money on 9v batteries. I work in music and I use 9v for a lot of things. I have had ZERO issue with these. I use them for my active electronics in my guitars, I use them for my wireless transmitters. I haven’t had a single issue. I actually need to buy more. Stop spending money on disposable batteries.

Pros
  • Love it
Cons
  • The batteries feel heavy and bulky, making them difficult to carry in your pocket

Great Batteries best in my review

I have been buying EBL batteries for a while and I am very pleased with them. When fully charged, these batteries will measure less than 9.0V. My batteries measured 8.75V but do not let that discourage you as these batteries will last longer than regular disposable batteries. At least that is my own experience, and I own several EBL batteries from AAA all the way to these 9V ones.

Pros
  • The charger is easy to use, with simple instructions included, making it accessible for anyone to use
Cons
  • The charger may not be compatible with certain smoke alarms and other devices

Number one. on my review.

EBL is the best choice for me. I always look for quality and price. Chargers are quick and their batteries last for many recharges.

Pros
  • Just got these for my smoke detectors, so will update review at a later date.
Cons
  • The packaging is made of low-quality materials that can be easily damaged
