I bought this last time that it was this price. It works great. If weight is any indication of quality, this one should last because it's heavy.

Curious. Is this also good for charging car batteries that have discharged after a few months of inactivity? I have the battery tender which I got for $20 on Amazon, but I learned the hard way it can only charge batteries with 8 volts already, so I had have someone at Pepboys use their more advanced charger to charge it part of the way before the Tender would work.

I had a battery that had been sitting for probably a year or more in a vehicle. I forget what the voltage reading was, but I thought for sure that I had ruined an expensive battery. I was impressed at how this charger brought it from completely dead back to full charge. I've had chargers in the past that were aggravating as heck on a deeply discharged battery, but this one was hassle free.

This is a heavy piece of crap. Can't believe its FP. Just goes to show SD is stretching for deals

So which model would you suggest?

The weight of this unit is directly related to the fact it has a high current 50 amp output mode for jump starting. A simple 10 amp charger is much lighter but lacks the output to jump start a car with a dead battery.

Thumbs up.

$44.99 for me plus tax
Edit: I was on Sears website. Went to Kmart and got one for $29.99 thanks!

Other than "portable" in the description, I don't see anywhere if this unit has to be plugged in, or if it has its own battery. Can I jump-starting my car on the road, away from electrical outlets?

Edit: from just its looks and size, I'd say no own battery. What do you say?

Do you have any other suggestions?

This unit has to be plugged in. One tip-off is that it mentions noting about having a built in battery, or the capacity for same, but even putting that aside, units like this are plug-in only.

This unit was on sale in July for $27 so it's not priced at the lowest it's been, although by using shop discover the cash back matches that price. It's a good unit as it's automatic, charges both AGM and standard batteries, offers three charging rates.

Quote from nohomers1:
There seems to be alot of confusion over the different types of devices. Let me provide some explanation:

1) Portable battery jump (i.e. Peak 900):. These are a rechargeable battery that you keep in your car and hook up to your battery in the event it died (i.e. you left the lights on all night). It's the equivalent of hooking your car up to another car's battery with jumper cables. You plug the device back into an outlet to recharge it for it's next use.

2) Plug-in battery charger (i.e. this DieHard one): These are battery charges which plug into a wall and generally have adjustable current. They are intended for batteries which are dead or low and need complete recharging (i.e. a car that's been sitting for a few months while you were working on it, a lawn mower battery that hasn't been used since last year, etc). These are also used for completely recharging a dead battery. Remember that a completely dead battery will regain some of it's charge from the alternator in your car, but you ideally want to fully recharge your battery with a unit like this (or many shops will do it for you). I've heard that not fully recharging your battery after it's died and relying only on your alternator causes increased load on the alternator and may cause it to prematurely fail. I don't know how true that is in today's cars.

3) A battery maintainer: These are devices indended to prevent the scenario in #2 (i.e. prevent a battery that isn't being used from completely draining). This is ideal, as you really do not want an automotive battery to fully discharge. They are commonly used for vehicles that are used occassional/recreationally (i.e. motorcycles, vintage cars) or off-season downtime (i.e. lawn mowers).

I have a Peak 600, and have used it countless times. I will probably buy this recharger to use to fully recharge my battery when I return home after having jumped it with the Peak.
