12V rv batteries deep cycle are often used in cars, boats, solar power stations and other fields, but many people do not understand the charging voltage standards and low-voltage use limits of 12V batteries.

1.12v battery charging voltage standard number of volts

Generally speaking, the charging voltage of a 12V lead-acid battery is between 13.8V and 14.4V. The voltage in this range ensures that the battery is charged quickly and maximizes its service life.

However, in winter or when the temperature is low, the voltage should be slightly increased to ensure that the battery is fully charged. On the contrary, in the summer or when the temperature is high, the voltage should be slightly reduced to prevent overcharging leading to battery aging.

2.12v battery voltage below how much can not be used

When the voltage of the 12V battery is lower than 10.5V, it means that the battery can no longer supply power. In this case, if continued use will cause damage to the battery and shorten its life.

Therefore, when you find that the vehicle cannot start or the solar power station cannot work normally, you should first check the voltage of the 12V battery, and replace the battery in time when the voltage is lower than 10.5V to avoid unnecessary losses.

Do ancient lead-acid batteries have a future?

1, before the use of 12V lithium battery to replace the heavy lead-acid battery, and now there are civilian vehicles began to use lithium battery instead, such as BYD DM-i hybrid uses its own 12V lithium iron phosphate battery, weighing only 2.2±0.2kg.

2, the traditional 12V lead-acid battery industry chain is very complete, cost-effective, even if it is gradually retired on the vehicle, it can continue to be used on the non-mobile platform, and its industrial scale is in the decline period.

3, lead-acid battery weight reduction task is extremely difficult to achieve, this science and technology tree can point the skills have been full, the next thing to do is to use lithium-ion batteries to replace lead acid.

4, the advantage of the lead-acid formula is that the thermal runaway is very low, and very few vehicles spontaneously combust because of the thermal runaway of the lead-acid battery. In addition, the operating temperature of the lead-acid battery is as wide as -20℃-60℃, which is unmatched by most of the current lithium batteries.
