Q: My Snap On Portable Power 1700 jump starter no longer has any power, even after it has been on charge?
A: Firstly, confirm that the mains charger is working - see F.A.Q. 2 and that it is the correct charger for the Snap On Portable Power 1700 (the label of the Pack will match the label on the charger.)
If that is OK, then leave the Snap On Portable Power 1700 on continuous charge for 48 hours, because you may have taken more out of the battery than the charger has had time to replace. If the unit still has no power, then it is likely that the battery needs replacing.
Please contact us for advice.
Q: How can I prove that my mains charger is working correctly?
A: The best way to check charger operation is to plug it into the Snap OnPortable Power 1700 - but NOT the mains electricity yet! Observe the Yellow 'Charging' L.E.D. You should see this L.E.D. illuminate then dim until it goes off. At this point, connect the charger to a mains electricity wall socket to power it up. The large Yellow 'Charging' L.E.D. should now remain lit.
Alternatively, the charger can be checked with a Multimeter after discharging it, as described above. The expected voltage is in the region of 16 - 17 volts for the 1.5A UK Charger.
Q: How do I know when the Snap On Portable Power 1700 jump starter is fully charged?
A: Push the red button and when fully charged the Large Red 'Charged' L.E.D. will come on.
Q: How often do I need to charge the Snap On Portable Power 1700 jump starter?
A: The Pack should be charged after each use. It is best to keep it fully charged to ensure enough power when it is needed. (For full details please see Operating Instructions supplied with the unit.)
Q: Do you have an alternative way of charging the Snap On Portable Power 1700 jump starter?
A: Yes, it is possible to charge the Pack using the Male to Male Lead supplied with the unit, enabling connection to a 12V cigarette type adapter on the vehicle. Please be aware that this socket is not always 'live' unless the ignition is switched on.
Q: What is the C.C.A. (Cold Cranking Amp) figure for the Snap On Portable Power 1700 jump starter?
A: The battery type used in the Snap On Portable Power 1700, and other jump starters, is a compromise between the power and capacity of a true 'cranking' battery and the lightweight, small size and portability of the Valve Regulated Sealed Lead Acid battery (V.R.S.L.A.) that we use.
The small V.R.S.L.A. battery is not intended to be used as a 'cranking' battery. It is limited in its ability to disperse the heat generated quickly enough when used as such. For this reason the manufacturer states that the battery can develop 300A for a maximum of 6 seconds only. It should then be allowed to rest for a period (we recommend 3 minutes) before cranking again.
Q: What is the life-expectancy of the battery in my Snap On Portable Power 1700 jump starter? [See also F.A.Q. 2]
A: The battery manufacturer expects the battery to last for several hundred cycles. Achieving this entirely depends on the depth of discharge and temperature at which the battery is used and stored.
Life-expectancy is greatly influenced by the configuration in which a battery is used. The 2 main configurations for a battery are 'float' and 'cyclic'. A car battery on a vehicle is an example of a 'float' configuration, whereas 'cyclic' configuration involves a battery being discharged, then when this 'cycle' has finished, it is charged up before being discharged a further time and so on.
A battery used in 'float' configuration can give a long service life and is measured in years, however, a battery used in 'cyclic' configuration, as in the Snap On Portable Power 1700, has its life measured in charge/discharge cycles. This is not likely to be as long as a 'float' type battery.
Deep discharge of any lead acid battery will reduce its service life.
It should be noted that persistent, continuous cranking of a difficult or reluctant vehicle engine can cause permanent damage to a jump starter battery. The build up of heat created inside the battery by this action can melt the battery's internal connections.
Q: Why does my new Snap On Portable Power 1700 jump starter not start as many vehicles as my friend's old one?
A: A new battery does not reach full capacity until 3 - 5 charge/discharge cycles.
Q: Can the acid in the battery spill out if the Snap On Portable Power 1700 jump starter tips over?
A: No. The technology employed in the construction of the battery ensures that it is spill-proof.
Q: Do I need to top-up the electrolyte in the battery of the Snap On Portable Power 1700 jump starter?
A: No. The battery is a maintenance-free type.
