Answer:
Virtually all packs like this can't be returned even within 30 days. The reason is because shippers insist the OEMs send them with a low charge, yet the first thing a customer needs to do is fully charge it when received to even try it out.

The reason is because shippers insist the OEMs send them with a low charge, yet the first thing a customer needs to do is fully charge it when received to even try it out. Since shippers won't accept a fully charged battery for returns, these can't go back. So make sure it's something you want before ordering. Feel free to add comments with questions of how long it'll run things etc before ordering if you have expectations of such. see less Virtually all packs like this can't be returned even within 30 days.

Answer:
This is a 12V battery about 1/3 the size of most car batteries. When you first connect it up via the jumper cables, a fair amount of power will be "shared" between batteries (which I think of like having 2 buckets of water where you connect them and the water level balances out depending on how much each had and the si… see more This is a 12V battery about 1/3 the size of most car batteries. When you first connect it up via the jumper cables, a fair amount of power will be "shared" between batteries (which I think of like having 2 buckets of water where you connect them and the water level balances out depending on how much each had and the sizes). Although that can provide a fair "charge" pretty fast, it is still limited and will never "recharge" the other battery 100%. You could use this as the "source" for a device like the "Wagan 9796" which will "pump" power from this into the car battery (moving more power than just the cables connected will do), but again with this being much smaller than a car battery it will only partly refill it (like you can't refill a 5 gallon bucket from a 2 gallon bucket). If you have this connected to another battery and plug in its AC charger, power will go to both batteries, but the chargers in these only put out 0.5 amps where it can take 24 hours just to charge itself if heavily drained (so it can take several days to charge itself and a drained car battery connected up together). So that's probably why most manuals say "disconnect everything while charging" discouraging doing that, but it can work (if you don't mind the time it takes). Otherwise if you want to be able to charge a car battery in less than a day, you'll want a 5-10 amp car charger. see less This is a 12V battery about 1/3 the size of most car batteries.

Answer:
These packs have a good chance of starting most cars, yet no one can promise you "It's sure to ALWAYS get you going" since every situation is a bit different. The ads like "1500 peak amps" may make some think it's a lot better than the car battery with 500CCA, yet those ads are quite misleading. After you buy it and lo… see more These packs have a good chance of starting most cars, yet no one can promise you "It's sure to ALWAYS get you going" since every situation is a bit different. The ads like "1500 peak amps" may make some think it's a lot better than the car battery with 500CCA, yet those ads are quite misleading. After you buy it and look at the manual you'll see things like "Don't crank a car engine for even 5 seconds or you'll damage the battery inside the pack" which is one example showing how powerful it really is. I have other examples if you wish like OEM details on the "Crank assist amps" test that is quite different than "Cold crank amps" testing (add comments if you want those). In any case, the power these have may be enough for many situations, but there's always possibilities of a car battery having shorted cells draining power faster than it can be sent or such where it may not work. So realize it's limits where just as it weighs ~1/3 that of a car battery, that's a good estimate for the power it can give you in comparison.
For a diesel truck, I'd want at least 2 of this size pack to try such (just as you have 2 car batteries in it). The 12V power this has can be connected up where trying it is better than looking at the dead car thinking "what do I do now?", but it has it's limits. I even ask one OEM rep about that expressing concerns over the ~80 amp draw for glow plugs lasting 10 seconds seems like an automatic violation of their "Don't crank a car (or have high power draw) for even 5 seconds" rule. The rep I ask responded with "The glow plugs draw is very taxing on the battery, but I don't count it against the crank time". Not sure if he wanted to avoid saying "Our product can't handle it" while he did share my concern, yet he did emphasize getting a bigger pack for trucks (like double this size) while one like this size would be OK for a VW diesel or such. So that's my best advise (and luckily I've not had to jump such a truck). see less

Answer:
Yes. When it is fully charged there is a yellow light that will come on and will say maintaining battery. The instructions say you can leave it plugged up.
