  1. Can You Replace Alkaline Batteries with NiMH Batteries?

    NiMH batteries from Vapextech can, for most applications, be a substitute for alkaline batteries despite their voltage differences. Alkaline batteries are rated at 1.5 volts and they will only deliver 1.5 volts when fully charged. As they start to discharge the voltage of alkaline batteries will continue to drop.

    Over the course of their discharge, alkaline batteries average roughly 1.2 volts (very close to the voltage of a NiMH battery). The main difference is that an alkaline battery starts at 1.5 volts and will gradually drop to lower than 1.0 volts. NiMH batteries will stay at about 1.2 volts for most of their discharge cycle.

    There are a small number of cases where their actual voltage difference is crucial. For devices such as a radio, where a higher voltage means a stronger signal, you could opt for an alkaline battery, although they are more expensive than rechargeable NiMH

  2. Why Now is the Time to Swap NiCd to NiMh Batteries

    If you have solar lights in your garden you should consider replacing NiCd rechargeables with Vapextech's range of NiMH batteries.

    Our team often get asked if you can use NiMh (Nickel Metal Hydride) batteries in solar lights that currently use NiCd. Luckily you can and we will explain the benefits of making the switch during this blog.

    Why Choose NiMh Batteries

    Here are four reasons why you should choose NiMH batteries -

    Long Shelf-Life - New NiMh batteries can remain unused for anywhere between 3 and 5 years. Vapextech recommends using your NiMH rechargeable batteries sooner to keep your solar lights shining bright.

    No Memory Effect - NiCd batteries do have issues attaining a 'memory' that reduces the life of the battery. NiMh
