These Uniross rechargeable 9V batteries are made using brand new Hybrid or Hybrio technology. This new technology basically mean that these rechargeable batteries have all the attributes and cost savings of rechargeable batteries but also have the benefits of everyday batteries. They are fully charged, ready to use on arrival. They also stay charged for up to 12 months, unlike ordinary rechargeable batteries which go flat quite quickly, annoying when you come to use your camera and the batteries are flat. They can also be recharged in your existing NiCd/NiMH battery charger, no special charger required. We call them PRE-chargeables.
To improve the performance of these rechargeable batteries make sure your customer completely discharges and recharges these batteries for the first 5 cycles.
