Disposable Batteries- Zinc Air Batteries. A perfect travel companion

One solution is to keep a Disposable Batteries or Zinc-Air battery handy.

These disposable batteries fit most popular Nokia, Ericsson and Motorola phones.

You get about three to five times the working capacity of the rechargeable battery that came with the phone.

For example, if you get three days of standby plus two hours of talk time from your rechargeable, multiply those numbers by three to five times to figure out what the power the Zinc-Air will provide.

The actual power you get from the disposable battery depends on the type of phone you have, whether it is analog or digital and even how far you are from the mobile phone companies antennas.

The batteries have dozens of tiny little in its case so that air reacts with the compound inside to make electricity. Herein lies one of the few drawbacks to the disposable battery. If you keep your phone in a tight fitting leather case, these batteries won't work.

Still, it's a small price to pay for the convenience. The disposable batteries cannot be recharged when they are used. They have to be discarded. The makers of the product say thezinc-air batteries contain no heavy metals or hazardous compounds. They are made of materials that are environmentally benign and fully recyclable, says their maker. They can be intermittent if not snugly fit into the phone.
