Advice on Battery safety and installation

Tip and Tricks for installing battery terminal covers.

Advice, Tip and Tricks: Battery Safety and installation:

Safety First!

Always wear safety glasses when working on batteries.  Once, when I was much younger, I was cleaning the corrosion on the battery in my then girlfriends car.  (Maybe it was because I was a teenage gearhead but oddly enough I remember the car more fondly than her. )  Anyway I was scrubbing away with a wire brush and the brush flicked a piece of the green acidic crud right into my eye.  After thoroughly washing it with water I was OK but I learned an important leasson... always wear safety glasses when messing with automotive batteries. 

Batteries produce explosive gas - keep away from flames and sparks: Batteries produce hydrogen gas: that's the stuff that brought down the Hindenburg and later the Space Shuttle Challenger.  Do not smoke around batteries.  Do not expose to flame or spark.  Here's another true story.  My brother was trying to jumpstart his wife's car but the battery post was loose and it wasn't making connection.   He told "Red" to crank it while he wiggled the battery terminal and post.  The wiggling caused a spark and the battery exploded blowing the top off the battery and splashing him and the under hood area with battery acid.  He was wearing glasses and got immediate attention to wash off the acid.  He was lucky; it could have ended worse. 

Use caution connecting booster cables: Connect jumper cables to the discharged battery first. The hydrogen gas get created as the battery discharges.  So sparks around a charged battery are less likely to create an explosion.  Another good idea is to connect positive to positive then connect the negative to something on the engine in stead of the battery.  That way if a spark is created it happens it happens away from the battery.  Of course be careful for all the usual stuff on the engine...spinning fans, belts, hot stuff, etc.

Remove jewelry when working on batteries.  Another true story... I work at a shop repairing tractors with a guy Named Bobby Blix.  He was one of the best mechanics I ever had the privilege to work with.  He never wore jewelry on the job.  One weekend, on a trip to Las Vegas, a friends car broke down.  While he was working on it he shorted the battery positive post to ground thru his metal wrist watch band.  The watch was glowing red before he was able to react.  I'm sure the pain from the burns wrecked the Vegas weekend and he had a scar in the shape of a wrist watch around his wrist to remind him of it.  

Always remove ground wire first and connect it last.  Most modern cars are negative ground although many old cars were positive ground.  For this discussion we'll assume negative ground. Why disconnect the ground first?  Until the ground is disconnected the engine, and car body are all connected to the negative battery post thru that ground cable.  If you slip with the wrench and it bangs into the metal battery box, you will create a huge spark as the current from the positive battery post finds a path to ground by going thru the wrench, the car body and the ground cable.  Avoid these problems. Always disconnect ground cable first and connect it last.

Wash Your Hands! - I hate to sound like your mother but she was right this time.  Batteries contain lead and sulfuric acid, both of which cause all sorts of bad things. Always wash you hand after working with batteries.  Lead causes heavy metal poisoning and battery acid can cause severe chemical burns,  Do NOT eat, rub your eyes, hug your kids, smoke, snuggle up to your honey or go to the bathroom until you have washed your hands.  You don't want chemical burns in embarising places. 

Don't pound on battery terminals to get them to fit on a battery post. I was once with a buddy when we took his car to the auto shop in one of these discount big box stores.  His car's battery was getting changed under warranty.  The young kid doing the work must have thought that thosee cables were held on with nails because he took out a hammer and started thumping the terminals to get the to fit on the battery posts. This can damage the internal connection from the post to the plates and break the fragile seal around the post, assuring acid leaks and corroded cables for as long as you keep that damaged battery.  Special "spreader" tools are made for opening terminals so they will fit. You can even use a large flat blade screwdriver or 2 end wrenches  in a pinch. See pictures:

Stuck Battery Terminal?  Use a Terminal puller.  terminal pullers are handy little devices for removing stuck battery terminals. See picture...  Battery terminal puller
