The lead acid battery in my aging Xantrex Xpower Powerpack 300 jumper pack is gotten increasingly weak, so here I attempt to restore it. It wasn't quite successful, and I found that one of the cells is failing.
An older battery like this will generally have very deteriorated/dissolved positive plates and will need replaced. Also, these are AGM batteries, so they didn't come with loose liquid floating around, (which is why they are unspillable) but rather all the white stuff you see inside is saturated with the electrolyte. If the positive plates would happen to be good, you severely diluted the acid. My guess is that your positive plates are shot, especially the shorted cell. When the plates dissolve, the material is still conductive, so shorting becomes more likely. Some of the cells may not have much white in them because the mats can become stained from the deteriorated plates; this battery is not recoverable.
thank you for the vid . how ever there isnt any videos on how to repair the circuits inside them . going back to topic 85% are only bad cell the rest if the battery leaked acid on the board itself causing damage
I watched a video were they sacrificed a old car battery by using the battery acid and pored it into a battery like this. It did revive the battery but I dunno if it made it like new 2005 wow it's old. In 2005 I was 3 years old I was born in 2002. thanks for the video.
There's two reasons for that. First, the 65W rating is only what it can put out for a short time. The continuous rating will be slightly lower. Second, 65W is what the laptop power supply can *output*. No power supply is 100% efficient, so if it's outputting 65W, it will be inputting 10 or 20 watts more than that. I have a 75W inverter which can only run a laptop on a 65W power supply for a few minutes before it shuts down. You should still be able to charge the laptop with it turned off, though.
Hi there, I have just tried this and it works!! The battery pack is a few years old (5+) but it doesn't get much use. The starting voltage after an overnight charge with the standard charger was 12.6v. I connect the Opitmate 6 to it and this morning its 12.9v so that's a good sign!! Now it's up to 13.1 v. ....
its far from worn out.only used a handful of times. not exactly sure what happened. i hooked it up to my battery bank on my camper{ 2 trojen 6 volts hooked up for 12 volt bank } which were down to 4.0 volts after sitting neglected for about a year thinking i could put a bit more juice into them .but as soon as i switched on the jumper pack i heard a loud click and the meter on it went to dead .took it back home to recharge but not holding a charge at all. was way to expensive to not think of getting it repaired.
@@themaritimegirl check your charger if like most it's not fully charging the battery should charge to 14.8 13.4 float charge it shouldn't be discharged below 12.2 I took apart a black and decker right on the battery was written do not discharge below 12.2 float charge is 13.4 and full charge is 14.8 and the charger was 12 volts no wonder it failed it was dead to start with checking other units they're the same the best way to charge it is use a battery maintainer and plug it into the cigarette lighter plug I use my cigarette lighter plug to cigarette lighter plug and put the charger on the other end clip the negative or black one around the barrel making sure it is touching the spring contact and the positive clamps to the center pin on the cigarette lighter plug i'm making up an adapter using two adapters from side post to top post putting it in a box and tieing a ù cigarette lighter plug to it right now I'm trying to find how to replace the battery in a nautilus booster pack the battery I found is around70$so I'LL have a300$ unit
