Cordless Razor & Electric Shaver Batteries

Replace the Battery, Not the Razor

A quality electric shaver is a real investment, and when it stops holding a charge, buying a whole new one can feel like an unnecessary expense. In most cases, the shaver itself is perfectly fine — the battery is simply worn out. Replacing it is usually far more affordable than buying new, and it gets your razor performing like it did on day one.

Battery Mart stocks replacement batteries for a wide range of cordless razors and electric shavers, so you can keep the shaver you know and trust running for years to come.

Understanding Shaver Battery Types

Most cordless razors and electric shavers use one of two rechargeable battery chemistries: NiCd (Nickel-Cadmium) or NiMH (Nickel-Metal Hydride). A smaller number of newer models use lithium-ion batteries.

NiCd batteries are the older standard. They're reliable and built to handle a high number of charge cycles, though they tend to offer less runtime per charge compared to newer options.

NiMH batteries deliver more capacity in the same physical size, which often means longer shaving time between charges. In many cases, a NiMH battery can be a direct upgrade over an aging NiCd.

Both types are typically rated at 1.2 volts per cell, with many shavers using a two-cell configuration for a combined 2.4 volts. The key specs to match when ordering a replacement are voltage, capacity (mAh), and physical size.

A Note on Installation

Unlike swapping out standard AA or AAA batteries, shaver batteries are usually soldered directly to the internal circuit board. That means most replacements require a soldering iron to install. If you're comfortable with light electronics work, it's a manageable DIY project with the help of a how-to video for your specific model. If soldering isn't your thing, a local electronics repair shop can often take care of it quickly and inexpensively.

Frequently Asked Questions

What type of battery does my electric razor use?

Most cordless razors and electric shavers use either a NiCd or NiMH rechargeable battery. Older models tend to use NiCd, while many mid-range and newer models have moved to NiMH for better capacity. A smaller number of high-end shavers use lithium-ion batteries. Your shaver's manual or the label on its existing battery is the best place to confirm the chemistry and specs.

Do electric razors use lithium batteries?

Some do, particularly newer premium models from brands like Braun and Norelco. However, the majority of cordless razors on the market still use NiCd or NiMH cells. If you open your shaver and find a cylindrical cell with solder tabs, it's most likely NiCd or NiMH. Lithium-ion shaver batteries tend to look different and are typically found in higher-end models.

How do I know which replacement battery to order?

The easiest approach is to check the battery inside your shaver. Look for the voltage (usually 1.2V or 2.4V), capacity in mAh, and physical dimensions. You can also search by your shaver's model number, which is usually printed on the underside of the unit or inside the head. If you're still unsure, our team can help — just contact us with your model number and we'll find the right match.

Can I use a higher-capacity (mAh) battery as a replacement?

In most cases, yes — as long as the voltage and physical size are the same. A higher mAh rating means more stored energy, which often translates to longer runtime per charge. This is one reason NiMH batteries are a popular upgrade over original NiCd units.
