other manufacturers. Whether we make it hear in the U.S. or overseas at
one of our affiliate sites, our product is always manufactured with
high quality materials and workmanship. We are not a fly-by-night
company. If you have a question about our product, or about batteries
in general, we'll do our best to answer it. We work regular U.S.
business hours (9am to 5pm Eastern). We have the experience and
resources to provide you with a one-stop shop for all your battery
What is the difference
between GEL and AGM batteries?
Both AGM and GEL batteries are sealed, valve-regulated, and
non-spillable batteries. The electrolyte in AGM batteries or gel
batteries does not flow like a normal liquid. For AGM batteries, the
liquid electrolyte is stored in a sponge-like matted glass fiber
separator material (Absorbed Glass Mat). In GEL batteries the
electrolyte is mixed with an additive that changes it into a gel-like
material. This method of storing electrolyte protects the plates during
lower temperatures (near 32°F) the power declines faster in a
GEL battery than in an AGM battery. AGM batteries perform better than
GEL batteries during high current, high power applications and in
extremely cold environments.
or wet batteries are more easily replaced by AGM batteries than GEL
batteries because GEL batteries have a different charge requirement
(mainly lower finishing voltages).
Q: Why should I choose UPS
or Fedex instead of U.S. Postal Service or Economy Shipping when ordering lithium
The United States Postal Service sometimes uses passenger aircraft to
send parcels across the country and overseas. We are required by the
D.O.T. (Department of Transportation) to place warning labels on the
outside of our packages containing primary (non-rechargeable) lithium
batteries. The warning label reads "CONTAINS PRIMARY LITHIUM BATTERIES.
FORBIDDEN FOR TRANSPORT ABOARD PASSENGER AIRCRAFT". This warning is
related to the volatile nature of primary lithium batteries if/when
they are involved in an accidental fire. If packages with this warning
label are shipped via US Postal Service, the package will automatically
be diverted to a ground shipment. Ground shipments with the U.S. Postal
Service have no guaranteed delivery time and can take several weeks in
transit. For this reason, we highly recommend using UPS or FedEx for
this type of shipment. UPS and FedEx will use cargo only aircraft (not
passenger aircraft) for their packages.
What is "memory effect" and how can I avoid it?
Memory effect is the loss of battery capacity or performance due to the
crystalline formation that appears on the inside of nickel based
batteries when they are subjected to shallow discharge followed by
recharging. This occurs in Nickel Cadmium (NiCd) and Nickel Metal
Hydride (NiMH) batteries. The best way to avoid the memory effect is to
exercise your battery by discharging your battery fully before
recharging (down to 1v per cell, or until the equipment complains of
What is "Shelf Life" ?
Shelf life is the amount of time a manufacturer recommends that a
product sits in storage without being used. It is measured from the date of
the date of purchase by the end user!).
For example: When a manufacturer or a reseller
states a shelf life of a product, it is not necessarily intended to
mean "battery life", it is meant to be a guideline to use when marking
a product with a "use by date". This information can be
useful to a consumer so that old batteries are not used before this
Q: Are NiMH batteries
NO. Please see description above. NiMH batteries, however, do have much
less memory effect than NiCd.
Q: Can I rejuvenate my old
batteries that have been idle for a long period of time?
Many myths exist about being able to rejuvenate old batteries, but we
recommend replacing old batteries to avoid equipment failure during
use. Batteries are chemical systems and will deteriorate over time.
Q: Why can't I purchase
lithium ion or lithium polymer rechargeable cells?
Most battery companies will not sell individual lithium ion or lithium
polymer cells. This is a safety/liability issue. Lithium rechargeable
cells are a completely different system than NiCd or NiMH and require
proper charging. Lithium battery cells are usually 3.6 or 3.7 volts,
which is quite different than the 1.2v cells of Nickel based batteries.
If lithium cells are assembled, charged or discharged improperly, they
could explode. This is why lithium ion and lithium polymer battery
packs are always assembled with safety circuits.
Q: Why can't I find
rechargeable lithium AA batteries?
See question above this one.
Q: Why didn't my order
qualify for the discounted shipping rate?
Our discounted shipping offers will usually have some restrictions. For
instance, if the item you are purchasing has low value or high weight,
then we cannot offer a discounted shipping rate because we will not
make any money. Our goal is to provide you with quality product and
service at a reasonable cost to you. In order to continue doing this,
the items we sell need to be profitable. ALSO - PLEASE BE AWARE THAT
YOU MUST USE YOUR MOUSE TO CLICK ON THE LITTLE ARROW WHICH IS A DROP
DOWN LIST, ALLOWING YOU TO CHOOSE DIFFERENT SHIPPING METHODS. If your
order qualifies for the discounted shipping, then you must "choose" it
from the list of shipping methods.
Q: What is "reversed
Polarity refers to the orientation of the positive and negative
portions of a battery. Batteries attach to a device through its battery
terminals (positive and negative). The battery terminals may be in the
form of wire leads, a connector, metal plates, or clip on type
adapters, to name just a few. Positive is usually signified by a red
wire or a (+) sign. Negative is usually signified by a black wire or a
minus (-) sign. When connecting a battery to a device, you need to make
sure that the positive and negative of the battery are connecting to
the correct points on the device. This is usually made fool proof by
the device manufacturer, but when purchasing a replacement battery,
such as for a cordless phone, you need to be aware that there is a
possibility that the positive and negative terminals of the battery may
be reversed. Always keep your original battery for comparison.
Q: What is "battery
Without being too technical, battery capacity is the rating used to
describe how much energy can be stored by a battery. The higher the
number, the more energy a battery can store. Most battery cell
manufacturers will use similar standards when rating their batteries.
You should be aware, however, that some companies will label and market
their product based on the "maximum" battery capacity - this gives the
appearance of a product to have a higher capacity than a competitor's
which may be labeled with the "average" or even the "minimum" battery
Q: Why can't I purchase a
NiMH battery to replace my old NiCd battery?
Care needs to be taken when replacing older NiCd batteries with NiMH
batteries. These chemistries are similar, but do have different needs
when charging. If a NiMH battery is charged improperly using a charger
designed to charge NiCd,
then the battery or charger could overheat and
damage equipment or injure a person.
