Advantages of Custom-manufactured Nimh Battery Packs
Custom fabricated NIMH (Nickel Metal Hydride) battery packs are rechargeable, durable, and provide higher energy density than nickel cadmium and lead acid chemistries. NIMH battery packs are ideal for portable and stationary applications, offering transportation advantages and simplified battery pack design compared to Li-Ion.
Mission-critical portable devices for commercial and industrial applications require custom battery packs that can withstand harsh environments.
Weijiang's custom NiMh Smart battery packs not only provide state-of-the-art power features, but also effectively communicate battery status to host devices or charging solutions. This type of data communication is critical to ongoing device functionality.
Lithium VS Nimh Battery Packs
Custom rechargeable battery packs using lithium cells can provide both high voltage and excellent capacity, resulting in an extraordinary high-energy density. Many applications, such as cell phones, medical devices, electric vehicles, and others require such a high-energy density that only lithium chemistry will do. However, for many of the applications that we see, custom Nickel Metal Hydride (NiMH) battery packs are more cost effective to design and manufacture and do not come with all the potential hazards associated with lithium products.
NiMH batteries have been around since the early 1970s. The technology has been driven by its high-energy density (vs NiCd and Lead Acid), being environmentally friendly, good cycle life performance, and with having a good safety and reliability record. And while NiMH battery packs don't need the complex BMS (battery management system) essential with lithium batteries, we do design and manufacture BMS systems for NiMH packs that help the battery pack last long and communicate with the customer’s device in order to provide the same information as a complex lithium pack.

A nickel metal hydride battery (NiMH or Ni–MH) is a type of rechargeable battery. The chemical reaction at the positive electrode is similar to that of the nickel–cadmium cell (NiCd), with both using nickel oxide hydroxide (NiOOH). However, the negative electrodes use a hydrogen-absorbing alloy instead of cadmium.
Nickel Metal Hydride (NiMH) custom battery packs are designed to provide lightweight, high-capacity energy, long-term reliability and advanced safety features.
NiMh custom battery packs feature a proactive design philosophy to provide simple, portable energy for a variety of applications. Portable, custom-designed NiMH battery packs are also ideal for projects requiring proven durability, low operational risk, and shorter development times than other chemicals.
NiMH battery packs can power many types of commercial and industrial applications over a wide temperature range while reducing development costs.
Some of the more attractive features and benefits offered by smart NiMH battery packs:
Nominal battery voltage is 1.2V
Usable voltage range per cell is 1.0V-1.45V
Charge rate up to 1C
Multiple cell size options
long shelf life
Environmental friendly
For new NiMH batteries, it is necessary to cycle them three to five times before they reach peak performance. Battery cycling can be achieved simply by using the batteries and recharging them or using the charger's built-in conditioner.
Insert your NiMH batteries into their charger and allow them to charge completely. The safest thing to do is let them charge overnight so you know they have fully and completely charged. Install the batteries into any device or gadget and let it run until the batteries fully discharge.
Most applications with high energy consumption and demands are where NiMH battery packs excel. They are also suitable for applications as backup power sources, where NiMH batteries have a BMS to control charging and discharging to increase the life of the battery pack.
The main gases released by NiMH batteries when they are overcharged or overdischarged are hydrogen and oxygen. The battery case should not be airtight and should be strategically ventilated. Isolation of the battery from heat-generating components and ventilation around the battery will also reduce thermal stress on the battery and simplify the design of a proper charging system.
You can not. However, NiMH battery packs are one of the most difficult to charge accurately, and since the BMS solution is so cost-effective, we recommend that you use it in your designs. The charging of NiMH batteries is based on forcing current through the battery, while for Li-Ion and Lead-Acid batteries, you can control overcharge by simply setting the maximum charge voltage. Therefore, installing electronic safety devices will increase the overall life of the battery.
Here are the two major differences between the two chemicals:
Cost: Nickel-metal hydride batteries are less than 50% of the production price of lithium batteries in the final battery pack, and less than 75% of lithium batteries in product development. While NiMH has some regulatory and other development steps, it is still well below lithium.
Size: Lithium batteries are lighter and smaller than Nickel Metal Hydride (NiMH) batteries, but Lithium batteries have an average capacity of only 1500mAh, while NiMH batteries average 2200 mAH.
