VARTA Microbattery with its brand Power One has over 100 years of experience in developing innovative battery technologies. Featuring with its consumer-focused extra long tabs, Power One batteries are manufactured at the world's most up-to-date and biggest production site for hearing aid batteries in Ellwangen/Germany—well recognized for manufacturing quality and detailed precision. Subject to Germany's stringent safety guidelines and quality checks, every cell is tested for its electrical and mechanical characteristics
in compliance with its specification.
VARTA Microbattery's Power One uses an environmental management system certified in accordance with the ISO 14001 standard. It also uses eco-friendly materials for the packaging.
"At Power One, every battery is tested before it leaves the works—100%. The comfort packaging then receives a quality seal, which safely seals and protects it. The rust-proof batteries themselves have an outstanding service life, especially where high power demands are concerned. Behind all this is a special, patented technology that enhances the cell voltage. The environment is equally important to Power One. Hence, Power One is the only manufacturer in the world to provide a complete range of environmentally friendly rechargeable nickel-hydride batteries, together with chargers, for hearing aids."
We carry four models of Power One hearing aid batteries [zinc air batteries] in size 10, 312, 13, and 675. We also carry the Power One IMPLANT Plus cochlear battery [size 675].

*As with any new rechargeable battery, ACCU Plus batteries will not reach full capacity right out of the package. Several power discharge [uses] and charge cycles will be required. These rechargeable hearing aid batteries should be stored at normal room temperature, and during extended periods of non-use, they should be removed from your hearing aid devices. Even during passive states, a low current does circulate which can deep discharge [i.e., drain] a battery over a period of time. Such a discharge harms the battery by creating an irreversible loss of its capacity.
The VARTA Microbattery Power One brand of hearing aid batteries is an excellent choice for your hearing device. Determining which battery type, zinc air or Ni-MH ACCU rechargeables, for most is determined by their practicality for everyday use. To help you with this choice, the pros and cons for each battery type are displayed in the charts below.

Power One boasts a selection of chargers for ACCU batteries giving you the ultimate in portability and versatility.
The Power One Pocketcharger [or Card Charger as it is sometimes referred] will charge one or two rechargeable Power One ACCU hearing aid batteries. It is supplied with three different inserts which allow you to charge P10 ACCU, P312 ACCU, and P13 ACCU Plus batteries! The Pocketcharger works independently of a power outlet. It is powered by a VARTA Microbattery's rechargeable lithium polymer battery which charges your hearing aid batteries in 2.5 hours. You can recharge your ACCU Plus batteries up to 18 times before needing to plug in the charger. To preserve battery life and durability, the charger is equipped with a refresh safety function which first fully discharges partially charged batteries. Similar to the pocket charger, but exclusively for ACCU P675 batteries, the Power One 675 charger contains many of the same features as including the ability to charge one or two of your ACCU P675 button cells and its discharge function. Charge time for your P675 ACCU batteries is 5 hours.
Also available is the Power One series of Penchargers which allow you to charge P10 ACCU, P312 ACCU and P13 ACCU rechargeable hearing aid batteries. Powered by two AAA batteries, these ultra portable units charge your battery in five hours. To improve battery service life and performance, pen chargers drain partially charged cells prior to charging, similar to their pocket charger counterparts.
