will the beast charge itself after jump a dead battery?

Yes, it should. It will be drained significantly after charging a dead battery but it should have no problem recharging after that.

My unit came with a charger but only recharged the battery once before it stopped charging. The stun bat itself is very cool when you have a fully charged battery. The manufacturer really needs to provide a better charger. Thanks for asking the question because I forgot all about the thing and needing a new charger which should be free of charge.

Not only will it not jump start a dead battery, if the battery is too dead, it will not even charge it, as it needs to "see" a minimum voltage before it starts to charge.

This is a battery maintainer, your batt. should be charged before you use this.

Just be aware of the difference between a completely run down battery attended to immediately, and one that has been totally abused / ignored forever. Attempts to bring zombie batteries back to life are an iffy proposition, and if they don't - don't blame the charger. -grin-

No. Just connect it directly to the battery. It works great for me. The battery is always filly charged.

Yes, make sure to follow the instructions on charging the battery or it will need to be replaced. �

Yes, it's also supposed to start charging again once the battery drops to a certain point (I've never left mine plugged in on maintenance mode so cannot verify this).

I would say yes as long as the battery isn't totally drained. The battery needs to be charged because it's a maintainer to keep a battery fully charged all the time! I think it's to small to charge a totally dead battery. The battery tender only puts out 1.5 volts and a regular battery charger puts out 12 volts to charge a totally dead battery.

No, that is a misprint or something of the sort, it is not at all suited to jump start a dead battery. However, if you were to leave it hooked up to a (nearly but not entirely) dead battery for 10 minutes, that would usually be enough to get the car started unless the battery itself is not just drained but also worn out or damaged/defective/etc, or unless it is very cold outside.

No, this goes straight into the charging port. You can get an external battery charger if you port is messed up.

It might, depending upon battery size and how discharged it is - if it is totally discharged, nothing may bring it back, but if it is just really low, you might try to pre-charge it with a regular charger and then maintan it ( which is what the Tender is for) wihe the Battery Tender.Remember, it is only 1.25 amp and I would think you might need at least 2 amps for charging very weak batteries

Yes it will charge the original battery. Although it has yet to give it a full charge. But it will give you about 95% charge, which isn't bad when considering the cost.

The battery was dead when i got it. It recommends u charge it before using it. I never had any problems with it. Once i charged it initially it was fine.

Yes it does, as long as it isn't 100% dead. If it is let it charge a few minutes first

No... but if you are talking about a battery that had the lights left on overnight and 'dead' it will not charge if it is below (I think 2 volts) some minimum voltage left in the battery. It IS very frustrating because the older 'not so smart' chargers would at least try to charge a dead battery where these smart ones won't work at all. I faked one out once by connecting a small motorcycle battery to my dead car battery and fooled the 'smart charger' to start working and then put the motorcycle battery back. Battery was fine after about 6-8 hours of charging.

Yes. You I'll need the charging cable that goes from collar to your outlet after replacing the battery. The battery from factory will only last so long. Mine arrived in the mail fully charged. You may want to contact the manufacturer of your collar for further details.
