Tip & How-To about Isuzu i-Series


This concerns any maintenance type battery.
What I mean is if you can pop a top/cap off a cell on your battery then my fix may just work for you and save you some of that hard earned cash.

If your battery has at least one bad or weak cell this is worth a try.
I test my battery cells with a battery charger on high.
with the cell caps off so you can look down inside the cells like you were checking the water level watch for bubbling to occur in each cell after the charger has been on it for a couple of hours.
If you see several cells bubbling but one is not or any others are not then this trick applies to you.
Go to the fridge and grab the lemon juice. If you don't have any you will need some but before you go I must warn you that I have only rejuvenated 4 battery's out of 20 tried.
Now you might say that isn't the best of records however how much is 4 time the cost of your new battery?

I'm a skinflint from way back when dirt was first an idea and I enjoy spending my money on other things then frivolous items like replacing car parts.
Once you have the lemon juice take 3-4 cap fulls and pour it into the cells that are not bubbling.
There is something about the citrus acid that works on a bad or weak cell.
Keep the battery charger on over night and then check to see if you got lucky. I allow it to sit another 24 hours after the charge and without the charger on it and then test the battery with a meter. If it shows 12 volts then even if you didn't see active bubbles you may have still fixed it enough to start your vehicle.
I thought of this because I have one sitting right here and it is the 4th one I fixed. So rather you get lucky this time don't be afraid to try it on the next one that goes bad. You will get lucky one of these times and you will be sitting at the movies with you mate thinking thanks Raz for the battery trick, While your necking away in bliss not paying a bit of attention to the movie.
Good Luck, The Raz Shack

Can I add distilled water to a maintenence free battery, it get discharge easily.thanks

When a maintenance free battery needs a topup it usually indicates the battery is close to failing, though with care such a battery might still give good service for some time.

Never top up a discharged battery unless the electrolyte level is so low it can't be charged. In that case top up just a little and then trickle charge for a day and repeat until the normal level is restored.

That type of battery has the huge advantage that each cell can be checked with a battery hydrometer to ensure all cells are in a similar state and the electrolyte is clean. If one cell has dirty electrolyte it is wise to allow it to stand until gravity has done the work of settling that disturbed sediment.

battery drains when sitting

There would have to be something that is shorting out, causing a drain on the battery. Either that or check the cells and make sure there is water in them. The way you do that is pop the tops off with a screw driver ( you will be able to tell which part pops off ) and look down into the battery and top it off if needed. Be careful TRY NOT TO TOUCH THE CAPS to anything really but especially clothes. Hope it helps!
