They do. We guarantuee performance for up to three years after production. After this we cannot guarantee the battery will perform as well as it’s supposed to.

Never charge Ni-MH batteries with a Ni-Cd charger. There are significant differences in charging conditions between those two types of batteries.

Battery leakage can be caused by various problems. Read on to learn more.

Battery leakage is caused by forcefully discharging, short-circuiting, or the safety valve releasing excess gas from inside the cell.

Battery performance greatly depends on the device and on the conditions.

Typically for an alkaline battery is a gradually decreasing voltage when it discharges, which means that for some appliances, which need a high base voltage to operate, the appliance stops working even while the battery has still a bit of energy left.

Never apply heat to batteries. Keep them away from any heat sources like heaters, candles, stoves and fires. Exposing them to too much heat could cause them to tear, leak or even explode.

The memory effect is an occasional defect, which occurs in Ni-Cd and Ni-MH rechargeable batteries, where the maximum battery voltage decreases even though the original power of the battery remains the same.

Mixed use or leaving the battery in the appliance can cause battery leakage.

Each battery has specific characteristics, depending on their chemical composition. Zinc carbon is a cheap battery for basic low-drain devices. Alkaline deliver good, dependable power (usable for any type of device, depending on the alkaline type). Lithium technology is a stable technology for smaller, yet demanding appliances. Zinc Air provide long-lasting, continual power.
