Good batteries you can use along with 10 watt solar panels in India.

10W solar panels are good for emergency uses and also for self sustaining systems that need power. It can be used to power single led flood light, security camera etc.

Or for charging mobile and lights with solar in areas where electricity is scarce.

You can buy a battery within a range of 5 Amh to 10Amh. A battery with low Amp rate will be charged fast with 10W panel but it will take more time to recharge a 10 Amp battery. So in this range, 7Amp battery may be the best option.

Batteries in this list are 12v batteries – because 10W, 12V solar panels are most common.

But Amp rate is not the only thing we should consider before buying a battery for solar charging. For example some lead acid batteries have a depth of discharge(DOD) very low.

These batteries are designed for high amount of current in a small time period.

What we are looking for deep cycle batteries which can discharge to a low level. So we can use either deep cycle lead acid battery or lithium ion batteries. Or any other type of rechargeable battery with a good depth of discharge.

As of now, number of options are limited. Not many good 7Amp batteries are available online now.

May be because of covid 19 situation. But below are some good options i found.

So following list is of two categories. One is deep cycle lead acid batteries and other is lithium ion batteries. Lead acid ones are more affordable than Lithium ion batteries. But are heavy and not as effective as lithium ion batteries.

Lithium ion batteries are costly, lightweight and can be discharged to a very low charge. It is more efficient than lead acid batteries but obviously more costly.

If price is not a problem and you need light weight, then go for Lithium ion battery. You can also build your own lithium ion battery pack using old laptop battery cells, connected in series & parallel along with a BMS(battery management system).
