Hydrogen is released during charging of a lead acid battery.
Is a battery solid liquid or gas
it means it can run on batteries and gas

No, the batteries in an electric car are much different. Normal automotive batteries are lead acid batteries. Most electric cars use Lithium-Ion batteries.
batteries need to be replaced
Any lead-acid battery system when overcharged will produce hydrogen gas.
Batteries should be changed every 6 months. Some can last up to a year.
Rechargeable batteries are getting more and more popular. You can purchase them anywhere that sells regular batteries, except gas stations usually. Try going to Wal-Mart.
Hydrogen is discharged during the charging process of lead acid batteries, sealed batteries are a misnomer, they are only sealed against liquid leakage.
not unless the engine is also on, but it does waste the batteries
Over 95% of hybrid cars use gas only as fuel. From that they generate electricity and store it in batteries for later use to supplement the gas engine. The remaining hybrid cars (called plugin hybrids) use gas too, but can also be plugged in to keep the batteries charged.
Even if a multi gas detector claims it can run on batteries, they should only be used as an emergency power source. An alarm clock can also run on batteries, but it'll drain them within a matter of days if the alarm clock isn't plugged into an AC outlet. Multi gas detectors are the same. While many models can run on a couple of 9V batteries, don't expect them to last more than 48 hours on a single pair of batteries. However, that doesn't mean batteries are useless. Keep batteries plugged in just in case the power goes off, but don't rely on them.
