So glad we got the branded spare

Got this as a spare battery for our doorbell so that the camera isn't without a battery whilst the single one we had charges. Very happy with the spare, glad we got the branded one after reading some of the reviews of the off brand spare battery packs.

Excellent Battery Life

Purchased as a secondary battery so that I can always have one charged up and ready to go when the other has run out of charge. I usually average around one month of use per charge, but it varies depending on how much activity occurs to trigger the camera or it’s light.

Bien utile quand on utilise l’appareil en mode indépendant.
