Custom NiMH Rechargeable Battery Packs

Discover the ideal rechargeable battery pack solution

Lithium Ion, Rechargeable NiMH, Alkaline or even Sealed Lead Acid?

Maybe just some of the options you have thought about if you’re in the middle, or just beginning to developing a new product. If the thought has not crossed your mind, we recommend that you definitely begin to think about it soon!

Countless times, we have had customers come to us in the middle of a project, requiring a battery pack that simply cannot fit within their device or meet its power requirements. This usually results in changing the design as well as prolonging both timescale and budget.

If you have started to worry about your project’s battery requirements, contact our Technical Team who are happy to assist you.

For applications used repeatedly, a rechargeable NiMH battery is a trusted and safe chemistry capable of powering your product over and over again. NiMH can withstand up to 1,500 cycles depending on your choice of battery. Out-performing the older NiCd chemistry, NiMH is often more cost effective and easier to transport than Li-Ion.

Benefits of choosing a NiMH Battery Pack

NiMH rechargeable battery packs offer clear logistical advantages, especially when compared with lithium-based alternatives. Since NiMH cells are not classified as hazardous goods under most regulations, they can be shipped, stored, and handled with fewer restrictions. This reduces both the paperwork and cost associated with transporting battery-powered products, which is particularly important when shipping internationally.

NiMH batteries also have fewer storage limitations, meaning they can often be held in bulk without temperature-controlled environments or extensive risk assessments. For OEMs and service providers looking for a reliable and regulation-light battery chemistry, NiMH packs offer a practical and compliant power solution.

NiMH battery packs continue to be a popular choice across industries due to several additional benefits:

• Environmental friendliness – NiMH contains fewer toxic materials than older chemistries like NiCd, and can be more easily recycled.
• Good energy density – While lower than lithium-ion, NiMH still offers a practical balance between size, weight, and runtime.
• High cycle life – Modern NiMH cells can withstand hundreds of charge/discharge cycles with minimal degradation.
• Low self-discharge options – Newer variants retain up to 85% of their charge even after a year in storage.
• Cost-effective for medium-energy applications – Especially in tools, medical devices, lighting systems, and cordless consumer electronics.
