Hello There!I have an Eliminator Power-Box 800 that worked fine the first season we purchased it. The following year we tried to recharge it but it didn't work. It's been in storage for 2 years and, recently, I took it out to see if I can do something with it.No matter how long I plug it in to charge, the display on the unit does not show any information. I opened it and removed the battery from the circuit and it tested around 2 volts with no load.I can buy a new battery for about $70(can) but, before I spend the money, I would like to know if there is a way to test the battery properly to be sure it is the problem.Thanks! What kind of battery is it? (Composition; like NiCad, nickel cadmium, NiMH, nickel metal hydride, or something else?)It might be the recharger circuit for the battery (is it internal to the unit, or are you using an outside recharger that may not be the correct one for the battery composition type you're using)Specific battery types need specific chargers and charge times.
It SOUNDS like the battery, but after long disuse, some battery types can be cycled several times to regain most of their charge capacityWhat have you got? I don't know Harald. Years ago I bought a 'sealed' lead-acid battery for my car, but it wasn't really sealed, as the 'add water' tops were still there and I could remove them.I don't know what they're turning-out lately.If Simon doesn't see a way to replace the electrolyte in his, it sure sounds like he's going to have to buy a new battery.Simon, whatever happens, Harald is right, you need to recharge that battery once in while whether you're using it or not.Otherwise if you put it back into storage and forget about it, you'll need another new battery again next time.Good luck with this.
I don't know if you know.You can ADD water to top-off a lead-acid battery, but as Harald said, a sealed battery should not have lost any water.What I was talking about was fully replacing the 'water', which is not just water, it's a sulfuric acid/water mixture made for lead-acid batteries.At the least, your sulfuric acid mixture in the battery is useless now. At the worst electrolysis has caused sulfation of the plates that compose the cells within the battery.If the plates have bad sulfation, adding new electrolyte will not help it.Be careful with what you're 'do-it-yourselfing' doing. Those batteries are high amperage and can explode.If the battery case actually is 'sealed', don't mess with it, just replace it (the core charge on the old battery can be exchanged on a new battery, to save you a few bucks).If you're messing with this, use good rubber gloves and a face/eye shield in case of acid splash or detonation. So, this is where I'm at with this thing:I disconnected the battery from it's Eliminator circuit. Then, I connected a regular car battery charger to it and left it to charge.After 6 hours, the no-load voltage was 6.5 volts and going down slowly. Putting a charge (small light bulb), the voltage would drop much faster. I had to go away for a day and did not want to leave the battery on tension, so I disconnected everything.Now, 2 days later, the no-load voltage is down to about 2 volts.According to what you guys mentioned in this thread and what I read on the internet, I can conclude that this battery is dead.
I decided I will not attempt to open the battery and mess with the water and/or chemicals.So, I think I will risk to buy a new battery.Thanks to all of you!
