Ultra-tools

Durofix and ACDelco top quality cordless tools are all supplied with Li-ion batteries

Advantages of this type of battery

Much lighter than other energy-equivalent secondary batteries.

High open circuit voltage in comparison to aqueous batteries (such as lead acid, nickel-metal hydride and nickel-cadmium). This is beneficial because it increases the amount of power that can be transferred at a lower current.

No memory effect. Charge when needed, our biggest battery on takes 40 mins to change most only take 20 mins

The Self-discharge rate of approximately 5-10% per month, compared to over 30% per month in common nickel metal hydride batteries, approximately 1.25% per month for Low Self-Discharge NiMH batteries and 10% per month in nickel-cadmium batteries.According to one manufacturer, lithium-ion cells (and, accordingly, "dumb" lithium-ion batteries) do not have any self-discharge in the usual meaning of this word. What looks like a self-discharge in these batteries is a permanent loss of capacity  On the other hand, "smart" lithium-ion batteries do self-discharge, due to the drain of the built-in voltage monitoring circuit.

Components are environmentally safe as there is no free lithium metal

Lithium-ion Battery Technology

Lithium-ion battery technology is an important innovation in the early 1990s, and is the fastest growing trend in the power tools segment. A Lithium-ion battery is a family of rechargeable battery technology that lithium ions move from the negative electrode to the positive electrode during discharge, and back when charging. The Lithium-ion batteries are popular these days because the numbers of advantage over competing other battery technologies. Lithium-ion battery is a low maintenance battery with no memory effect that means you do not have to completely discharge before recharging; and it is no scheduled cycling is required to extend the battery’s life; it is lighter weight than other types of rechargeable batteries for a given capacity; it with a low self-discharge rate about losing 5% per month which compared to a 20% loss per month for a NiMH (Nickel-Metal Hydride) battery
