Charging Time For Rechargeable Batteries

This is my first time purchasing rechargeable Lithium Ion batteries with a built-in USB charging port. That's a very convenient way to charge the battery especially if you forgot the adapter at home.

Good charger for Watson 9V rechargeable batteries. Very quick charging time.

I use these batteries in everything. They last a long time for a rechargeable.

These batteries last a very long time, but because they are all rechargeable now I would never have just one.

Charging 2 batteries at a time, just great

The battery lasts for a long time . I love using the rechargeable battery over the batteries.

I have been using Watson rechargeable batteries for years in all my cameras and accessories and found them very dependable with a long charging life.

Not much to say here. It is a big improvement over having to haul around multiple AA rechargeable batteries. Initial charging was quick and so far it has performed well.

These batteries are game changers, individual USB C charging is one of the best ideas I have seen in a long time. No more bulky chargers or old style rechargeable AAA/AA that will not power most devices due to a lower voltage/current limitation on the old style rechargeable. As a A/V Installation Technician I have many tools with regular battery requirements. Multi-meter, network tester, cable toner, signal generator, laser level, flashlights etc...I am now saving a lot in the cost of disposables without impacting my tool use, great job Coast! and top notch customer service.

Coast “AA” Rechargeable Batteries 4 Pack, Model #30982 is a GREAT set of batteries. These batteries each have a built-in Type C charging port, and the 4 lead Type C charging cable is included with the batteries. The nice feature of this charging cable is that the input side has a standard USB Type A along with a Type C conversion adapter so it can be used with literally any traditional cell/smartphone as the charging power source. As a result of this unique charging cable, you now no longer have to carry/use a bulky charger base to recharge the batteries. I really like the fact that each battery has its own LED (Light Emitting Diode) indicator charge light (red while charging and green when completely charged) and each rechargeable battery has the Coast overcharge/discharge protection circuit to protect the operating of life the battery. Depending on the charge that remains in the battery when it is recharged will determine how quickly the battery recharges to maximum strength, usually in a half to one hour time period. The rechargeable battery size is the same dimensions when compared the same size non-rechargeable battery, so they fit and work great in flashlights, radios, etc. where you have used traditional, non-rechargeable batteries. I really like the fact these batteries are corrosion resistant as I have ruined some flashlights in the past with traditional leaky batteries when they die. These batteries are an excellent choice to use in order to be environmentally responsible compared to the traditional throw away batteries! According to Coast, these batteries can be recharged up to 1,000 times so I am very impressed. This represents true cost savings when compared to buying traditional non-rechargeable batteries. I am a true believer in the performance of these Coast rechargeable batteries!
