Subject to aging, even if not in use – storage in a cool place at 40% charge reduces the aging effect.Requires protection circuit to maintain voltage and current within safe limits.Low Maintenance – no periodic discharge is needed there is no memory.Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.Does not need prolonged priming when new.High energy density – potential for yet higher capacities.Here are the advantages and disadvantages of both materials: The table below shows the industry average for discharge rate. These newer batteries from Sony, Panasonic and more has the ability to store their charge for longer than a year. NiMH has a higher discharge rate than poly but advancement in technology has caught up and today’s NiMH has a high retention rate. For instance, photographers and their flash guns. Nickel–metal hydride on the other hand is cheaper and it only makes perfect sense for those that will consume the entire charge within a few days. This makes it ideal for emergencies and long trips. This is due to the fact that once it is fully charged, it doesn’t lose its capacity as quickly as others. When it comes to choosing rechargeable batteries, Lithium-polymer is the best. Lithium-Polymer Portable Power Pack Charger 02 – NiMH vs. Ikea LADDA on the other hand is affordable, ideal for those looking for disposable rechargeable batteries on the go. If money is not an issue, go for Panasonic (They make batteries for Tesla). As shown in the table below, Panasonic’s Eneloop has the highest retention rate and cycles.

The battery has to be of a standard size to fit into the device but the capacity within that battery can differ. The term ‘battery size’ is often used, incorrectly, to describe battery capacity. The more energy storage potential a battery has the more charging it takes to maximize that potential. The other thing to remember about larger capacity batteries is that they can take longer to charge. Remember, the mAh is the measure of energy potential over time and not available power that can be delivered. If you’re replacing the battery and you have the option of a 2500, 3500 or 4000mAh battery that are fully compatible, bigger is always better. That assumes you’re not doing much with the phone. In our example above, a 2500mAh battery can theoretically power a phone for up to 25 hours on low draw. As long as the battery is fully compatible, has been obtained from a reputable seller and is authorized by the device manufacturer, your only real decision is the mAh rating. If you have a cell phone or device with a removable battery and need to replace it, all other things being equal, the higher the mAh rating the longer time between charges.
