Having a portable jump starter like the Century Jumper 850 can come in handy especially in urgent situations when your car battery goes dead or lacks the power to crank the engine. The best thing about the Jumper 850 is that it has a 12V DC power output to power up any power-compatible devices you have.
Replacing Century Jumper Batteries
The power supply in all Century portable jump starters come from sealed lead acid (SLA) batteries encased within. The Jumper 850 specifically uses the a 17Ah 12V ES Series SLA battery. At the date of this writing, the cost to replace the Century Jumper 850 battery is over US$100! But there's a proven way to save on that cost.
On very rare occasions, we do receive feedback from our customers that they're unable to recover their batteries even when using our Infinitum Desulfators. In most cases, the battery is simply too old and unrecoverable*. There are also those who cannot desulfate their batteries because an inadequate rated Amp charger was used. Some very sulfated batteries will require a higher Amp charger to 'force' a charge into the battery. This is because the high buildup of lead sulfate crystals on the battery plates, builds an insulating barrier preventing the charge to occur.
How you can recover 'stubborn' batteries:
CAUTION: This form of battery reconditioning should only be done by a professional as the battery should be monitored and if done incorrectly, the battery may over heat and explode.
It is important to know that desulfators work to recover batteries from sulfation but not the loss of active material that occurs through aging. The above mentioned charging method will only be successful for batteries that are relatively new with some active material still left in it. A battery with a desulfator installed from day one will still eventually expire due to aging which also means the depletion of active material within the battery. The difference with a desulfator is that you get a battery with its life span optimized up to 2 to 3 times.

Over the years, calcium has been added to lead plates to improve grid strength and conductivity, and reduce gassing and its self-discharge rate. With this, the low-maintenance or maintenance-free battery was introduced. However, the alloy plate is still consists of more than 99% lead. Whether the battery is calcium-calcium, calcium-silver, lead-calcium, or lead-antimony, it is still essentially a lead acid battery and suffers premature failure from sulfation just like any other lead acid battery. The Infinitum Desulfator reverses and prevents sulfation, typically restoring batteries to the best possible condition, maximizing its life span up to 3 times.
An excerp from Popular Mechanics:
HOW IT WORKS: MAINTENANCE-FREE BATTERIES
Like many things in life, the term “maintenance-free” is only partially true. Lead-acid batteries normally consume some of the water in their dilute sulfuric acid electrolyte during a normal charge-discharge cycle. It actually electrolyzes into hydrogen and oxygen and escapes as gas. So adding water periodically is necessary to keep the plates flooded. Maintenance-free batteries use a calcium alloy of lead instead of an antimony alloy, which reduces the amount of electrolysis.
In addition, the amount of free-standing electrolyte above the plates is designed to be much higher in a new maintenance-free battery. This means that there’s enough electrolyte to keep the plates covered even after a few seasons of normal use. So, during the battery’s normal service life there should be no need to add water. Any abnormal electrical system condition or high ambient temperatures may boil off more than the normal amount of water, however. Adding water may extend the service life of these supposedly maintenance-free batteries.
As long as there is still active material in a car or motorcycle battery and the plates aren’t shorted, any battery that fails due to lead sulfate crystallization has a chance of being revived and reused. This is not only limited to car batteries, but to ALL lead acid batteries!
There are already battery clinics in certain countries now that revive and recondition batteries, which are later sold back to customers at about 1/3 the retail value of a new battery. These batteries are given 6 month replacement warranties! The graph below shows a typical revival process of a 45 Ah Ca-Ca battery that had failed 2 years ago due to shelf sulfation. Note how the impedance and CCA (Cold Cranking Amperes) are inversely related. The CCA of the battery, initially at 112 increased gradually up to 321. The battery was originally rated at 360 CCA, and it takes about 180 CCA to crank a car.
In this particular example, the battery was revived by the Infinitum Desulfator in approximately 6 hours or so. Do note that not all batteries can be revived in such short periods of time. The speed of revival depends on the degree of sulfation the battery suffers from. Revival can take up to weeks if a battery is badly sulfated as more time is needed to break the lead sulfate crystals.
As Good As Almost New
With battery analyzers you will know how well a reconditioned or revived battery works. Measurements such as cold cranking amps and internal impedance (Ohms) can be taken to diagnose the battery’s health.
NOTE: This article is applicable to all lead acid based batteries, including Sealed Acid (SLA) Batteries, gel, deep cycle, maintenance-free or dry batteries. Whether the battery is calcium-calcium, calcium-silver, lead-calcium, or lead-antimony, it is still essentially a lead acid battery as these batteries consist of 99% lead.
