One advantage lead-acid batteries were thought to have was their performance in cold weather. At the moment, lithium batteries hold their charge for triple the time of lead-acid batteries. Lithium also holds a charge for much longer now. Just like power banks, lithium jump starters are rechargeable through common USB ports and easily found online from $60 to $100 - though some models are listed for much higher prices. Even so, they're generally small enough to store in the glove compartment, instead of the trunk. The typical lithium-based jump starter is roughly 1 to 3 pounds, though larger models can almost reach 10 pounds and 12” in length. Lead-acid models are usually fairly bulky and weigh from 30 to 40 pounds. Lithium batteries (mostly lithium ion, the type of battery inside your phone and laptop) can have significantly more capacity in less than half the space than a lead-acid battery. While some mechanics and car enthusiasts still consider lead-acid jump starters “heavy duty” due to their long standing reputation and their availability from top brands, the reality is that lithium technology has come a long way. Modern jump starters are mostly made with lithium batteries, which are far more versatile and can be much smaller and lighter.īest overall: NOCO Boost Pro GB150 Lithium Jump StarterĮditor’s pick: Anker ROAV Jump Starter Proīest for low prices: Gooloo GT1500 Jump Starter Battery Packīest multi-purpose jump starter: DeWalt DXAEJ14 Digital Portable Power Station Jump Starterīest for cold weather: Hulkman Alpha 85S Jump Starter Jump starters: Lithium or lead-acid batteries? They were also made with inefficient lead-acid batteries that delivered less than what you'd expect for their size. Jump starters used to be large and bulky, usually heavier and bigger than an actual car battery. Jump starters, also called jump packs, boosters and battery chargers, have become more common and far more accessible than before. However, nowadays, there are easy ways to jump start your car without having to rely on someone else to come to your aid. Otherwise, that hike would have become much longer than you’d planned. In the past, you needed to call a roadside assistance service or find someone with another car and jumper cables to get your vehicle started. Even worse, you could go for a hike and find the battery is drained when you get back, stuck in the middle of nowhere. It’s awful to hop into your car for work only to find out it has a dead battery.
