Yes, it is possible to get a portable battery for a car, there are many portable car batteries available in the market, starting from basic jump starters to personal power units for camping trips or power outages. These units come handy for their wide range of applications. Having a portable battery in a car ensures the driver a smooth journey with no constraints or concerns related to power. The portable battery not only ensures the safety of the people in the car but also enhances the comfort level by maintaining a continuous power supply to various electronic-based technologies.
These portable batteries are nothing but compact electrical energy storage units with useful built-in accessories and were traditionally developed as a more convenient alternative to traditional cables for jump-starting a car with a dead battery, a life savior when your old car battery might require a jumpstart and there are no other vehicles available
But with the advancement in power electronics nowadays the batteries offer a lot more than just jump-starting a dead vehicle, they can charge your electronics like phones and tablets with their built-in USB port, can power your laptops and high-draw computers. One can buy a battery booster with additional features like a built-in air compressor, AC inverter according to the needs. Keep in mind that these features will add bulk and mass to a jumper pack.
All battery boosters come with jumper clamps to be attached to the battery terminals, most of them offer reverse polarity protection. Some come with easily installed, semi-permanent attachments that allow you to quickly connect them to your car’s starting electrics without the booster clamps.
Most of these batteries come with multiple charging options starting, standard extension cords, and wall-plug adapters, USB ports in running vehicles, or cigarette lighter-style 12-volt male adapters.
Things to know before you buy a portable car battery
Its primary purpose: Most car battery jump starters and battery chargers offer some flexibility, but in others, the options are more limited to their purpose. While buying a battery keep in mind which battery’s feature will serve right for your needs.
Starting amps: For jump-starting, different engines require different rated jump starter batteries. Most manufacturers rate portable car starters batteries for types of engines, so look for starting or cranking amps reading and accordingly choose a jump starter battery.
Total storage capacity: If you want to use your portable jump starter battery and portable car battery charger as a backup or mobile power source then use the in amp-hours or milliampere-hours (1,000 mAh equals 1 Ah) value to determine how much electrical storage capacity you would need. A higher number means more electrical storage capacity.
Chemistry: Portable car batteries run from sealed lead-acid to absorbent glass mat to lithium-ion and recently, ultra-capacitors. Theweight, size, and, to a lesser extent, the cost of a portable battery depends on the chemistry, for example. Thesealed lead-acid battery booster takes more space than its alternatives.
Features: Having options are useful, but again more features add on bulk and weight. If you have a big vehicle like an SUV, you might want to carrybigger portable car batteries around, but the same couldn’t be said if you have a small hatchback. You can buy separate accessories like a small, powerful air compressor that works with jump starter batteries, but this approach adds to the cost. Its still cheaper than doing battery reconditioning
Temperature: Studies have shown that the temperature affects the functioning of a battery, even the performance of even the best portable jump starter options degraded significantly when it was cooled to zero degrees.
On the other extreme. Manufacturers recommend not storing batteries in high-temp environments or placing it in direct sunlight. If batteries are exposed to excessive temperature, they will stop working, bulge, and bubble, create sparks and flames, damage your device, or blow up. Extreme heat can lead to battery corrosion that shortens the average car battery life.
Conventional sealed lead-acid cells are heavier and discharge more rapidly than lithium-ion when they sit idle, but they can also be less sensitive to temperature extremes and significant physical impacts.
