One of the best cars on the earth, hybrid cars has two main components to consider-an electric motor and the battery. The battery generally lasts up to 200,000 miles. Although it usually lasts longer than warranty period, the old battery eventually goes stale, and each new battery costs around 3000$. One thing to remember: all batteries contain modules, and although the quantity may vary, the core principle stays intact. The factories simply replace modules and sell them as brand new! And that’s where you play your part. It takes around 700$ to fi x damaged module, and your battery’s life is extended for another 6-7 years. You should also note that a reconditioned battery has output 70% of the brand new battery output, which is more than enough. First remove the battery followed by rubber which protects the caps. Remove all the caps of the battery. Don’t keep any cap on. Don’t put the caps back. Charge the battery for about an hour, and you will see the bubbles on the holes. However, if there are no bubbles, reverse the positive and negative wires. Wait for about 2-3 minutes. You can now see the bubbles. Revert the wires back to the original position and recharge the battery for additional half an hour. If required, you can also replace the acid inside the battery while mixing new acid with distilled water. Later on, recharge the battery for a few hours, and you get a battery which lasts for a long time.
