How To...

Maximize Battery Performance
Across all battery types, there are several things that you can do to ensure the maximum production from your battery: Always store batteries in a cool and dry place, fully charged, before storing for longer periods of time. Never leave your battery on its charger for more than 24 hours, doing so will shorten the life of your battery. Keep your batteries clean. Clean dirty batteries with a cotton swab and alcohol. A clean battery will ensure a good connection between your battery and its device. Keep your batteries dry. Moisture can corrode contact points and limit charge/discharge performance. Do not leave your battery dormant.
Activate My NEW Rechargeable Battery
New batteries come in a slightly discharged condition and must be fully charged before use. It is recommended that you fully charge and discharge your new battery two to four times to allow it to reach its maximum rated capacity. An overnight charge (approximately twelve hours) is recommended. Note: It is normal for a battery to become warm to the touch during charging and discharging. When charging the battery for the first time, the device may indicate that charging is complete after just 10 or 15 minutes. This is normal with rechargeable batteries. New batteries are hard for the device to charge; they have never been fully charged and not “broken in.” Sometimes the device's charger will stop charging a new battery before it is fully charged. If this happens, remove the battery from the device and then reinsert it. The charge cycle should begin again. This may happen several times during the first battery charge.
Dispose of a Dead Battery
Many battery types can be fully recycled. Some types require special handling or processes that may require a fee to properly recycle the battery. We operate in full compliance with federal, state, municipal, EPA, and DOT regulations governing the disposal and recycling of dead batteries. Please contact us for specific disposal and recycling information for your dead battery.



Battery Types

Lithium Ion, Li Ion
Lithium Ion batteries are a rechargeable design with a high energy density in relation to its' size and weight. Li Ion batteries are the most common power choice for personal electronics and communication devices such as smartphones, laptops, and tablets, along with power hungry items like two-way radios. These batteries operate at higher voltages than other rechargeables, typically about 3.7 volts per cell, which means a single cell can often be used rather than multiple NiMH or NiCd cells. Lithium Ion batteries also have a low self-discharge rate to retain their charge longer.

Nickel Metal Hydride, NiMH
NiMH (Nickel Metal Hydride) batteries provide outstanding capacity in a lightweight, rechargeable format. NiMH is interchangeable with NiCd in devices while providing a more environmentally friendly profile. NiMH batteries offer higher capacity than NiCd, but with fewer cycles..

Lithium-Polymer, LiPo
A rechargeable battery. Lithium Polymer batteries do not require a steel can like AA and Sub-C batteries, so they can be manufactured in a flexible casing. Lithium Polymer batteries have a smaller charge-per-pound ratio than Lithium Ion batteries. They can hold a greater charge-per-pound than NiMH batteries and don't have the memory effect that Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCD) batteries do.



Battery Terminology

milli-ampere hour, mAh
mAh (milli-ampere hour) is a capacity rating that measures how much current a battery will discharge over a specified period of time (typically a one hour period). Higher mAh ratings do not necessarily reflect how fast current can be drawn, rather, for how long a current can be drawn. This capacity can also be displayed as Ah or Ampere-hour, with the rating equating to mAh/1000. Overall capacity will be influenced by other factors including temperature, depth of discharge, and speed of discharge.

Volt or Voltage, V
A unit of measuring electrical potential or pressure, all batteries are rated in volts DC. Voltage is based upon the electrochemical reaction that occurs in the battery, and can vary by battery types.
Original Equipment Manufacturer, OEM
OEM refers to the original maker of the battery or device. OEM batteries are often referred to as "original" batteries installed in a device. These batteries were part of the original specifications of the device manufacturer to power the device. Our replacement battery performance specifications can be measured against the OEM specifications to ensure the device will operate to the manufacturer's minimum standards.



Battery Performance

Self-discharge is the loss of useful capacity within a battery due to internal chemical reactions. Self- discharge will occur within all battery chemistries and will be influenced by temperature. Self-discharge will occur regardless of whether the battery is connected to a device or not.

Shelf Life
The amount of time a battery will retain an operable percentage of its stated capacity (calculated under ambient temperature storage conditions).
High Capacity
Capacity is the measure of the energy stored in a battery. Expressed in Ah (Ampere hour) or mAh (milli-Ampere hour), capacity defines the ability of a battery to perform under specified discharge criteria over a set period of time. A battery rated as High Capacity or Extended Capacity exceed OEM specifications and will provide longer run time than the original battery.
Temperature variances can have a dramatic impact upon the performance and life of a battery. High temperatures intensify the chemical reactions inside a battery and may cause permanent damage to the battery. Lower temperatures can slow chemical processes to the point where the battery performance may not meet the requirements of the device. Batteries are best stored, charged, and operated at room temperature, generally rated at 25°C (77°F).
