Keep the batteries at around 60°F. Extreme cold will drain your rechargeable batteries. Never leave batteries in a vehicle or shed where they might freeze because this can cause permanent damage. NiCad batteries are more tolerant than NiMH, and while early Li-ion were susceptible, Makita’s LXT batteries handle the cold surprisingly well. There are several steps you can take to help you get maximum performance from your power tool battery:

This rechargeable MAKITA PA18 power tool battery (cordless drill battery) can replace the original battery of the following part numbers:For all batteries a margin of 0.1V difference in the voltage is safe. If the capacity (Ah) of the battery is higher than the capacity of the original battery it will enable a longer life expectancy. Please ensure the battery that you are going to buy fits your power tool's brand, model number and battery's part number.

Battery Storage - If you don't plan on using the Power Tool battery for a long time, store it in a clean, dry, cool place away from heat and metal objects. Tool batteries can handle usually 800 to 1,000 charges. Don't recharge a drill battery if you've used it for just a few minutes. The problem might be obvious, sometimes they over heat and desolder a connection, or there is an obvious point where an arc/short has occurred. With NiCd and NiMH batteries, the power starts fading away the minute you start using it. That doesn’t sound particularly bad, but in reality you’re almost never getting peak performance. With Li-ion batteries, though the eventual drop-off is more dramatic, they deliver consistent power for longer.For all Makita PA18 drill batteries a margin of 0.1V difference in the voltage is safe. If the capacity (Ah) of the battery is higher than the capacity of the original battery it will enable a longer life expectancy.
