When shopping for refurbished batteries, there are several things to look for. You’ll want to make sure that you get a high-quality battery. Several kinds are made from lithium, NIMH, and the newer lead acid varieties.
When shopping for refurbished batteries, there are several things to look for. One of the most important is the date stamp. It’s sometimes straightforward, but it’s a good idea to take note of the year and month of manufacture.
While you are at it, look at the battery label. You can find some information on the chemistry of the car battery. This will help you decide whether or not to buy the best one for your vehicle.
For instance, a battery with a high CCA (cold cranking amps) rating might be your best bet if you have a cold climate. The car battery will need more energy to start a vehicle in the cold.
You should also check out your vehicle’s owner’s manual if you’re in the market for a new battery. You can find a minimum CCA rating or the battery’s other most important number.
The BCI (Battery Council International) is a standardization body for battery sizes. Most group numbers are two digits and indicate the battery’s dimensions and location.
The BCI also has a small display of the battery’s most exciting features. These include a battery’s naming capabilities. Several other items are included in the BCI code.
Other essential items to look for include the size, the terminal type, the CCA, and the watts of the battery. Generally, a 12V battery must have a voltage of 7.2 volts.
The correct battery can make your driving experience more enjoyable. However, not all batteries are created equal. Choosing the wrong model could interfere with your car’s performance.
The best way to find out what’s best for your vehicle is to ask the staff at a reputable salvage yard. These shops often help you choose the correct battery. Likewise, a certified mechanic can remove and replace your battery.
Precharged NiMH Batteries
You have many choices if you are looking to buy precharged NiMH batteries for your power-hungry devices. However, there are a few things to remember to ensure you purchase the best battery for your needs.
First, it is essential to remember that you should never store NiMH batteries uncharged. The internal structure of the battery is still being formed. As a result, if the battery is left uncharged for too long, the internal resistance will become too high, causing it to discharge quickly.
Another good reason to use rechargeable NiMH batteries is that they are safer than the older technology of nickel-cadmium (NiCd) batteries. Since NiCd is a heavy metal, it is very toxic to humans. In addition, it will also degrade with age.
Precharged NiMH batteries, however, have been designed to eliminate this issue. Instead, they are designed to stay charged for at least a year. This is much better than the standard single-use batteries.
Compared to alkaline batteries, the voltage of NiMH is much higher. It is rated at 1.2 volts per cell. This means it can deliver a higher current, allowing longer run times between recharges.
When buying batteries, you want to look for the mAh rating. Typically, the higher the number, the more capacity the battery has. Batteries rated 2000 mAh have twice the power of a 1000 mAh battery.
NiMH batteries also offer a lower self-discharge rate, reducing the recharges needed. Battery capacity is often listed on the packaging, online stores, or the device itself.
Some devices, such as radio-control cars, are known to be battery eaters. Although the number of recharges is minor, you may need a more expensive battery to power these gadgets.
Before purchasing batteries, consider the manufacturer’s warranty policy. You should also pay attention to customer reviews.
Memory Effect on Reconditioned Batteries
The memory effect is a phenomenon that causes a battery to hold a charge less than it is. This can cause disastrous results for appliances and car engines.
The memory effect is most common in nickel-cadmium (NiCD) batteries. However, it has been observed in lithium-ion (LiIon) batteries.
One of the simplest ways to overcome the memory effect is to discharge the battery completely. Alternatively, reconditioning the storm will bring back some of the lost capacity.
Some battery manufacturers recommend reconditioning the battery after about three to five years. If the battery is ten or more years old, it may not be worth reconditioning.
Another good way to avoid the memory effect is to keep your battery charged to the maximum level. Although this is not always feasible, it can improve the longevity of your batteries.
Other factors to consider when reconditioning your battery include the following:
- The age of the battery.
- The chemical composition of the electrode material.
- The type of discharge method.
- The rate of degradation.
A rechargeable NiCd battery, for instance, has a lifespan of around 1000 charges. Fortunately, technology has improved so that today’s NiCd cells are less prone to the memory effect.
The most important thing to remember is that the memory effect is most likely to occur in a high-load application, such as an electronic device. It is not a problem in a low-load application, such as an electric vehicle.
However, the memory effect does happen, and it is not as pronounced as it once was. Newer types of batteries can hold a charge even when not in use.
In addition, newer chargers are better at avoiding the memory effect. These include software adaptations and a dedicated battery charger. You can find these at your local electronics store or online.
