How to Store Cordless Drill Batteries?

Cordless drill advanced technology has several benefits. It is easy to carry and makes your work fast. But before buying such machines, you should first check their battery timing. Cordless drill batteries are long-lasting, but unfortunately, some batteries cannot stay long. As far as batteries are concerned, you don’t like it when your battery runs out during work. And you don’t want to invest more money in batteries. Some people gave an opinion to put the batteries in the fridge to don’t heat up. But it can destroy your battery as it gets wet. To avoid such things, you need to know how you can store your batteries, even your entirely dead batteries.

Cordless drill batteries are rechargeable, Li-ion or lithium batteries, and nickel batteries are rechargeable.

Li-ion Rechargeable Batteries

If your drill contains a Li-ion battery, you must know how to charge it to your battery lifespan. Do not charge your battery 100%; the limit for lithium-based batteries is 85-90%. Charge them if its voltage decreases to 2.5V avoid using if it is only 1.5 V low. If charging increased, it would decrease battery timing. Plug the charger out when charging is complete.

If the battery is fully charged and discharged, then it is calculated as one cycle. Half discharge and half charging mean half cycle. Suppose this battery has 600 cycles; by half charging, you can increase its cycle to 1200.

Nickel Batteries

Do not discharge these batteries completely. Or you can discharge them after 30-40 days as these batteries have a memory default. If you leave the charger plugged in after full charging, the heat starts producing in the battery. It is not dangerous for the machine if you discharge regularly, but it shows a low battery. These batteries can be stored for 3 to 5 years.
