EBL9V Rechargeable Batteries 9 Volt Lithium ion 600mAh Li-ion Batteries (4-Packs)

These days 9V batteries come in several different varieties - Zinc-carbon, Alkaline, Lithium, Ni-Cd, Ni-MH, Li-ion. The last 3 types are rechargeable and the first 3 - are not. A typical alkaline battery has more than 9V when fresh. A Li-ion cell has a nominal voltage of about 4V. A typical 9V Li-ion battery contains 2 cells, connected in series, so its nominal voltage is 8V. When fully charged such battery may develop up to 8.4V. Upon discharge the Li-ion battery voltage becomes smaller and may go as low as 6V. This is the limit, which should never be breached. According to the description the EBL 9V battery has many types of protection inside it, but I have never seen any of them in action.I bought 4 batteries several years ago and used them in scales, electric meters and smoke alarm. So far I have no complaints. These batteries last about as long as alkalines, but they are rechargeable. They are more expensive than alkalines to buy, but not that much more. In a long run they definitely save money. A typical alkaline battery capacity is 550 mAh. Compare it to the 600 mAh of this Li-ion battery.EBL batteries are made in China and you cannot trust any of the Chinese products. So I felt a reality check is in order. I fully charged one battery to 8.348V and discharged it with my trusty DL-24 load tester. Not sure what EBL does for their testing, I selected a 10 hr discharge cycle. It means the discharge current is 600 mAh/10 hr = 60 mA. The tester maintained this constant current throughout the testing. The discharge stops at 6V (3V per cell). At the end the tester showed the 473 mAh capacity. It is lower than claimed 600 mAh, but EBL states that new battery can achieve the best performance only after 3-5 charge-discharge cycles. It may be true and I did not check that.In my experience these Li-ion batteries work just fine. You just have to keep in mind that you will see 7-8V on these batteries most of the time. They will never develop 9V like alkalines. Some of the devices may not work with such low battery voltage, but so far I did not find any such devices. My scales, meters and smoke alarms do not have issues with the low voltage. If you have any concern, the only sure way to resolve it is to try.

These are great for my tens unit- saves so much money!

50% bad batteries: Order was for 4 rechargeable 9volt EBL batteries. Out of these 4, half (2) won't charge in the same manufacture's own charging unit (EBL). Is there any quality control before causing customers a big headache with processing a return?? Customers should not be used for testing their batteries.Update 4/28/25: EBL customer service reached out to me about this review: offered to replace all 4 batteries (only 2 were a problem). As promised, received 4 replacements within a few days, all charged successfully. Impressive customer service outreach :-))

I have purchased these before. They last a long time and the only reason I have had to purchase more are because I have lost some. Great batteries.

Ebl 9v lithium battery's great for smoke detectors

I've been using these for my Sure Wireless guitar system. Really pleased with them - the 600mAh hold up for several hours before needing to recharge. I had some 260s that would fade in just little over an hour, so these were a nice upgrade. These are a much cheaper option than trying to keep up with 1 use 9v.

Good quality. I will update the review after several uses.

I have been very satisfied with these batteries. I have been using them and recharging them for a few years now, and they continue to perform beautifully. That makes them a very good bargain.
