Questions & Answers

Will this unit charge my 2008 Toyota Hybrid Prius battery? I went on vacation and my battery is dead.

A few occasions I need a jump and the car would start up right away. Once running the hybrid battery would charge my battery. I hope this make some sort of sense!
Asked by: Mysty777
With a couple of exceptions it seems to be nomenclature that is making the answers not so easy to follow overall. What some have called "main" is better called the STARTER battery. The miss-called "hybrid" battery would better be called the car's ELECTRIC MODE RUNNING battery--it stores charge when decelerating and (along with the STARTER battery) during Fuel-Powered-Running mode. The STARTER battery serves mainly as a storage battery (between car engine starts) and has no part in driving the engine. The RUNNING battery provides power (that's voltage multiplied by engine current draw) when vehicle is running electrically and re-charges by the alternator when vehicle is being fueled with gasoline; it has no function for starting the car. Because the RUNNING battery serves no purpose for starting the car in fueled mode, no purpose will it have for storing electrical energy and accordingly no relevancy with the B&D Portable Jump Starter's or any other battery charger or engine starter. (Did you notice that it is incorrect to say that any battery can be started--a discharged battery can only be jumpered to another power source such as a charged battery to provide boost to start and engine; a jump starter itself is recharged by its internal inverter connected to an AC power source such as a wall outlet. Now, as for your starter battery's being "dead," my concern there--and another answer addresses this as well--would be just how long that vacation lasted since in the absence of a voltage leak such as a short circuit to chassis ground, a non-failing battery should not go "dead" for a very long time in storage and should recharge readily either by engine-alternator-powered or AC-charger-powered connection during normal, temperate or torrid climate conditions. So yes, after several minute's Boost-Power-On connection, the B&D or other brand jump starter--if its own internal battery is fully charged--should be able to help start your car's engine (so that your car's alternator can work to recharge your car's own STARTER battery. But, if that does not work--and assuming your Prius' own STARTER battery actually did go "dead" just waiting for your vacation to end, then odds are better than even that it is time for a new, internal-combustion, engine STARTER battery for your hybrid-powered car; if that battery is getting "up in years" since newly installed before or after you bought the Prius, then those odds are even better: that you have little or nothing to lose by simply installing a new battery to see if that fixes your "dead-battery-car-won't-start" problem. (And don't forget that some battery sellers--call them on the phone to find out--will test your car's STARTER battery if you can manage to get it out and over to the seller's store location,) To conclude, if you are really asking about whether or not to buy the B&D Jump Starter to hopefully solve your "dead-battery-no-start" problem, then that would depend upon whether or not you already own at least a battery charger with or without its own battery for IC-engine crank/start for boosting your car's STARTER battery from time to time. If not, then buying the B&S booster would not be wasted since it can provide both engine start boost and STARTER battery recharge capability--and it is very handy to keep locked in your cars trunk--and locked for sure since such an item is very likely otherwise to "disappear to thieves by its handle" in a heartbeat."

How do you charge the jump starter so you can use the cigarette port

Asked by: LEE
The unit has a built-in AC Charging adapter. Simply plug any household extension cord on the charger in the back of the unit to charge it.

Does the Leds indicator have to be On always after it charges???

I charged mine and all the led indicators have been ON since I charged it and doesn't turn OFF. I press the Battery Status but nothing changes. It has been ON since 2 weeks and still going.
Asked by: BitCloud
Same thing happened to me! Eventually the battery ran out and then it wouldn't charge again. I had to return it.
