How to choose rechargeable table lamp battery capacity?

For rechargeable table lamp, there are many battery capacity size in the market. Choose which one is better. Here will according to our experience to share how to consider this question.

Larger battery capacity, longer working time. Depend on this, we can choose as large as we want.

However, we have to also learn how much capacity for battery now.

In market, usually capacity have 1200mAh, 2000mAH, 2500mAh, 3000mAh, 4000mAh, 5000mAh, 5200mAh, 6000mAh, 8000mAh, 10000mAh.

According to the shape, there are cylindrical battery(18650, 21700), also have Lithium-polymer battery. Lithium-polymer because of poor cost-performance, what's more prone to bulging and electrolyte leakage. So if can use cylindrical battery, then will not use Lithium-polymer battery.

18650 mean 18mm diameter, 65mm length, 21700 also 21mm diameter, 70mm length.

18650 mainly at most one battery can reach 3000mAh. 21700 can reach 5000mAh, and 21700 have high cost-performance. Some battery how can be 10000mAh. Because two battery like 21700 together parallel, others same. So volume become big.

Rechargeable table lamp choose which battery, have to consider three way.

1.Weather lamp capacity can cover

2.The cost

3.How long we have to use.

In our opinion, lamp use at least enough brightness at least 8 hours, can use for one day not need always charge. So battery should be exceed 5000mAh.

If you want much longer and your lamp capacity size is enough big, can choose 10000mAh.If not, not need so big, because cost-performance will be poor.
