Car Battery Maintenance

  • Check the water level every couple of months. It should be just touching the bottom of the refill hole.
  • Refill the battery, when needed, with distilled water. Don't use tap water, which produces corrosion on the terminals.
  • Don't overfill the cells. Just to the bottom of the refill hole is perfect.
The following tips apply to all batteries, including maintenance-free.
  • To ensure good connectivity, clean the terminals periodically with a wire brush.
  • When removing a connector from a terminal, twist it from side to side and pull gently upward. Refrain from excessive tugging or prying.
  • When reconnecting a connector to a terminal, seat it down firmly on the post. A few gentle whacks from a rubber mallet will do it. Don't over-tighten and strip the nut.
  • After securing the connector, coat the whole post with Vaseline or Battery Terminal Coating Spray. This will reduce corrosion and rust.
  • If you keep having electrical problems (battery dies, car won't start, power is intermittent or weak), it's not necessarily the battery. It could be in the charging system, normally either a bad alternator or voltage regulator. A mechanic can test the system to isolate the problem.
These general maintenance tips will extend the life of your battery.

BOSCH Silver Perfect Maintenance Free (PMF) Battery comes with breakthrough Silver alloy technology. This means it offers greater electrical conductivity and better corrosion resistance, substantial increase in service life, and a totally maintenance-free battery experience.
  • Factory charged and sealed; so, no charging or topping required
  • Consistent power output
  • Withstands heavy loads
  • Greater acid volume above the plates (safety reserve)
  • Charge-eye indicator
  • Side wall ribbing
  • Polyethylene envelope separators
 The sealed maintenance-free battery has optimised grid geometry and contains calcium silver alloy that offers excellent cold start performance, improved power consumption during charging, greater starting power and longer service life. The water consumption is much less than conventional batteries because the labyrinth for gas condensation and return to the battery minimises the loss of water.
  • Faster charging
  • Better short-trip resistance
  • Long-life
  • Improved cyclic loading
  • 30% higher starting power
  • Minimises the danger of ignition from external sources

  • Longer life
  • Higher cranking power
  • Leak resistant
  • Low on maintenance. Special hybrid alloy minimises water loss
  • Extreme vibration resistance. Ribbed container withstands temperature extremes and shocks/ vibration damages
  • Factory filled and wet shipped
  • Better corrosion resistance with superior plate design and weld systems
  • No electrical shorts, with glass matt lined enveloped PE separators


  1. What do you think – has General Motors done enough, or do you still prefer to ride in a standard gasoline-powered vehicle?

  3. no doubt maintenance is very essential but Car batteries tend to last longer if located inside the vehicle rather than under the hood and you will rarely ever see one corrode.
    I also agree that factory installed batteries will only last 2-3 years.

  4. I think checking your car battery on regular bases is important & you should have good idea about when your car needs a battery replacement.

  5. Car battery maintenance is important for your car & checking and changing oil also plays key role in car performance and i must say that points you made is very interesting, did get good amount of information about car battery maintenance.
