Hi guys / ladies .
-If you own multiple cars, it maybe worth it to buy these 7 step smart battery charger n repair. Cost around rm2xx (depend on model).
-Initially I bought one to charge 12v battery for my moblie radio/repeater rig. Lately been using it to charge several of my cars battery ( already pulang modal) infact save me almost more than rm1k already .
-The downside it's not the fastest option. Takes several hours to complete the cycle.
yes. for multiple cars that are not driven constantly., a slow charger can save you huge sums of money.

Drycell more expensive and lifespan depends on the product goods also. sometimes u just bad luck. maybe max 1~2.5yr.
Battery water type are last longer if u able to mange properly. it also depends on the brand. For last longer dont put normal distill water. go to those accessories shop which have acid sulfuric to top up the water.

Use "Acid Sulfuric" better?
Petrol station not selling these? If want add battery water need purposely go Car Accessories shop add

DO NOT add anything other than distilled water into your battery (although i believe the "battery water" we get is not as pure as we like). anyway, adding sulphuric acid to your battery is the surefire way to kill it sooner. the battery works on the basis of a reversible reaction, remember le chatelier's principle from high school chemistry? that precisely what goes in your battery.
adding more sulphuric acid not only upsets the chemical balance and it is oxidation of the electrodes by sulphur that causes your battery to die, thus adding more sulphuric acid might actually speed up the process.
