A rechargeable battery that packs a real punch when it comes to power and versatility. Long-lasting power against a backdrop of superior performance.

Nickel Metal Hydride (NiMh) batteries have very high energy density, coming close to that of lithium cells, and are commonly used with high-drain devices like digital cameras with LCD screens, toothbrushes, and electric razors. Unlike typical alkaline batteries, NiMh batteries are able to handle higher loads for longer. They are similar to nickel cadmium batteries in that they both make use of nickel oxide hydroxide, but in NiMh cells a hydrogen-absorbing alloy is used at the negative electrode, instead of harmful cadmium. Before recharging, these batteries should discharge almost all the way in order to avoid damage to the cells and loss of capacity over time. Most smart devices, like GPS systems, will warn users when this critical point of discharge has been reached, prompting a recharge. When charging, a timed and fixed low current is the safest way to prevent overcharging, which can also cause irreversible damage to the battery.
