9V Rechargeable Batteries, POWEROWL High Capacity 600mAh 9V Li-ion PP3 Batteries for Microphone, Smoke Alarm, Electric Games, Walkie-talkies, and other devices(4 Pack)

these rechargable batteries will save lots of money as they will be used in medical equipment with normal batteries only lasting couple of days

Battery was slightly larger than branded ones as it is square and all the others have the corners rounded off, so it was a bit tight in my toys battery compartment.The battery took longer to charge than i expected but this may be due to the capasity. unable to comment on how long it lasts as it has only been a few days but it is dooing the job i expected of it.

From the moment the packaged arrived, I knew that this company had taken the effect regarding this product and it was good to see this. From the design of the package right through to having the batteries fully charged to use straight away. My batteries have been in use for two months and still going strong. I was so impressed, that I ordered another pack of four.

Low cost, Functionable and do the job. Only 600mAh but not an issue as bought a 4 pack.Would buy again

These hold a lot more charge than any others and are now our go-to choice across all battery sizes

Very fast delivery. Packaging is good, which is becoming a standard among several rechargeable batteries manufacturers. Similar to Bonai’s which makes me believe that they are all either different names for the same manufacturer or just copying each other!I as very excited to receive them as I have a device waiting for two 9V batteries. The big disappointment came when I could not fit them in any of my two chargers! Trying again and again, but they just don’t fit. Taking a close look at the top end where the positive and negative poles exist, made me notice that the battery shape is very rectangular with sharp edges instead of round/ curve edges. While both chargers has the standard 9V battery curved-edges shape. This is frustrating. How come I didn’t notice that when checking the product picture on Amazon. I re-checked the pictures and they were with curved edges, unlike the ones I received.It is very disappointing to have this tiny yet critical detail spoil the whole experience and turn these batteries useless for me. I am definitely sending them back to Amazon.I’m not sure if there are other chargers that might accommodate this non-standard shape, but they didn’t work with mine, which I bought from Amazon! So, to be fair, they might work somewhere else, depends on the charger. But it’s not a smart decision to have them manufactured with non-standard shape, and it’s definitely not honest to have different pictures of the product than the ones they send!

These batteries are a good product. Charge well and have a decent life. Worth noting that they may be a poor fit in a 'snug' battery holder due to their fuller sectional profile. May require slight modding of the holder to provide better seating.

For what I use the rechargeable, I can’t complain. Blood pressure monitor, remote control and mini torch. Value for money.

The batteries were placed in a smoke detector. The battery low continues to sound. Guess I have to get better batteries.

Parfait rapide à charger et économe.

Me gusta su calidad, precio y cantidadFuncionan después de haberlas cargado a tope como hay que hacer con todas las pilas recargables que se compran nuevas, aunque vengan algo cargadas no es suficiente y se dañan al exigir su funcionamiento normal al 100 por 100Vendrán como un 50% cargadas para su seguridad al ser transportadaa para que no hayan chispas no fugas de ácido etcUna vez cargadas a tope de pueden usar normalmente, eso sí, pasarán algunos ciclos de carga y descarga hasta que tenga su potencia máxima.Cuando lleven un tiempo diré que tal pero por ahora hacen su función en unas alarmas de humos que tampoco consumen mucho...Por eso por ahora las recomiendo y estoy muy contentoVeremos si duran o son un fiascoLo único que note es que pesan menos que una pila normal Alcalina, y eso no me gusta ya que a más peso creo que tendrá más consistencia y más capacidad de tensión, pero eso es un supuesto mío claro....
