This will then be confirmed when you have completed checkout. Based on a survey of 1, Which? When we surveyed Which? For more shopping tips, read our guide on how to buy the best rechargeable batteries.
This is because smaller cells could be overcharged and larger ones not fully charged in the same session, which can damage batteries over time. Batteries with different chemistries - such as nickel-metal hydride NiMH or Nickel Cadmium NiCad — shouldn't be recharged together either. Manufacturers often recommend that their batteries are charged best by the same brand's battery chargers. This is because they can adapt how the charger works to suit their batteries.
Some battery chargers are claimed to be able to recharge disposable alkaline batteries. We tested two the Deluxe Battery Wizard for alkaline and zinc-carbon batteries, and another battery charger for disposable alkaline batteries with Energizer alkaline batteries.

The Energizer Pro Battery Charger has an integrated LCD indicator which clearly displays the charging status to ensure your batteries are fully charged every time.
It provides battery overcharge protection by detecting a voltage change in charging and shutting off each cell pair when the battery is charged.

However, product formulas can change and there may be slight delays in updating the information online. Larger designs can accommodate up to 8 batteries. More bays can be very helpful in high-use situations, cutting down on your waiting time. Maybe the most important thing to think about is the safety of your battery charger. This starts with the build quality—frayed wires and broken prongs are the most common cause of shocks and shorts.
Chargers also frequently include features that protect the batteries from short-circuits and power surges while charging. A once common and helpful safety feature is auto-shutoff, which senses when a battery is full and cuts off the current.
This prevents overcharging of the battery and lengthens its usable lifespan, saving you money in the long run. The final piece of the puzzle is how long it takes the charger to fill up batteries. While you can find quick-charging options that fill up a battery in as little as an hour, the majority of chargers will take longer—up to 12 or 13 hours, in some cases. Energizer rechargeable batteries use a Ni-MH nickel-metal hydride reaction to store and release energy.
No, they do not. Also known as voltage depression or voltage depletion, this is a common problem with Ni-Cd batteries. It happens when the battery is recharged repeatedly when it has been only partially discharged, rather than fully discharged. Over time, the memory effect leads to lasting lower battery capacity. Luckily, Ni-MH batteries do not require a full discharge before charging.
Most Ni-MH batteries can be recharged up to 1, times before they go bad if properly cared for. Repeatedly discharging the battery completely will lower its maximum lifespan. The same goes for repeatedly overcharging the battery, or charging the battery too quickly.
If you avoid these power drains, you can get several years of use out of rechargeable batteries. Some Energizer battery chargers include a bad battery detection feature. This will give you an indication on the display when you insert a battery that cannot take a charge. They will often test your batteries for you for free. Your email address will not be published.
