Update () This a battery jump pack that is used to jump start a car. Some units have an ac adapter built in so you can charge the battery in the jump start pack.

500 mA AC charger question I have a (12 V, 600A, 22 Ah) Dynamite AutoPower battery (sealed lead-acid battery) for emergency jumps for my car and emergency power in case of a power outage. Download free q tip amplified 320 rar software. I have a Dynamite Power Pro Auto Power 300A portable battery recharger and I don't know where I packed the manual. Does anyone know what the recommended charge time is for this type of battery rechar.

My unit has a spot to connect the ac adapter to the jump pack so you can charge the battery in the jump pack. My ac adapter has been lost. I know I have to buy a new ac adapter so I can charge my jump pack, what I do not know is if the input (from the ac adapter) is 120v 60 hz I understand that the DC output needs to dc12v.

I do not understand the milliamps. The battery in the jump box is 12v 10 ah ( what ever that is). I just want a new ac adapter to charge the jump pack with that is not going to damage anything. Hi, Do not understand. The unit has a battery which is charged via the AC connection.

The unit provides a DC output supply. Do you wish to charge the unit battery using DC?

If so, there is this warning given in the guide 'It is possible to overcharge the battery when re-charging using the DC outlet. Over charging the battery can cause permanent damage and decrease battery performance. Only charge using DC supply if a 120V AC outlet is not available. Charging the battery this way (via AC connection) also safeguards the battery as there is built in protection from overcharging and damaging the battery, which is not provided when charging the unit battery via the DC connection. Hi, OK I get it now. Your unit (which is not the one in the link in my answer I suppose) doesn't have an inbuilt adapter.

In that case to charge a battery you need to do it a what is known as 'charge at the 10 hour rate'. This rate is the standard charge rate for batteries.

It prevents damage caused by overheating etc, which may occur at higher current values. To get the charge current value, you divide the battery capacity, in your case 10AH by 10 giving a charging current of 1A. However charging voltage for a battery should be higher than the battery voltage so as to prevent the battery wanting to discharge back into the adapter.e,g, car 12V batteries charge at 13.8V. So ideally to charge your battery you need a DC14V 1A charger. 15V will do but keep a check that the battery doesn't overheat.

Hi @ Dennis Green, I'd say not. You'd most probably damage the charging circuits and possibly the battery of the jump starter Most car battery chargers initially put out ~ 4A when charging a battery, which reduces as the battery charges. They can do this as a car battery is usually a lead acid type (not as critical when charging as other types of rechargeable batteries) and there is no battery management circuits in play when you charge them directly from a car battery charger, i.e. Battery disconnected from car and charger connected directly across battery terminals Looking at the specs for the charging adapter provided above, it only needs 0.5A to 0.7A to charge the jump starter. Obviously it takes longer to charge the battery with this amount of current, but most probably it is suited to the type of battery (and battery management system) in the jump starter. Is the center tap negative or positive on the charger for the PEAK 700? Their manual lacks detail for the charging apparatus.

It could be 24 volts ac, it could be 12 volts dc center tap negative, it could be 15 volts center tap positive It could be anything! I expect to see a polarity, voltage, and current rating however we see none. Also we do not know what the circuitry is inside this.
