So i opened up that little beast and turns out the CMOS battery can't be saved - already started getting these little crystals that form when battery acid leaked and dried again.

So i have been looking for a replacement, searching for 3.6V 20mAh on ebay... Seems these tiny Nickel cadmium batteries got out of fashion completely. There are however similar size Ni-MH ones.


Question - is it save to replace it by a Ni-MH battery? I don't know so much about batteries but i remember Ni-Cd have a bit different characteristics than Ni-MH. So just wanna hear that it's save and they will not catch fire or explode because they have different charging characteristics or anything.


Any comments welcome.

Well today i messed with one of my old Fujitsu INTERTOP Model 10. Was nearly getting crazy since it wouldn't save changes to BIOS, was back on default on every reboot.So i opened up that little beast and turns out the CMOS battery can't be saved - already started getting these little crystals that form when battery acid leaked and dried again.Checked the internet and seems this type ("GS SAFT 3GF20") kinda went out of fashion and disappeared around the end of the s...So i have been looking for a replacement, searching for 3.6V 20mAh on ebay...

Can You Replace a NiCd Battery with a NiMH Battery?

A Detailed Exploration

As technology evolves, so does the need for more efficient, durable, and environmentally friendly power sources. Nickel-cadmium (NiCd) batteries have been popular due to their durability and high discharge rates, but concerns over environmental impact and performance have led many to consider nickel-metal hydride (NiMH) batteries as a superior alternative. This comprehensive guide explores whether you can replace a NiCd battery with a NiMH battery, covering all necessary considerations from compatibility to benefits, and highlights how Himax Electronics can facilitate this transition.

Understanding NiCd and NiMH Batteries

NiCd Batteries:

• Made from nickel oxide hydroxide and cadmium.
• Known for their good performance in low temperatures and ability to deliver full rated capacity at high discharge rates.
• However, they suffer from the &#;memory effect&#; and contain toxic substances, posing environmental disposal issues.

NiMH Batteries:

• Use a hydrogen-absorbing alloy instead of cadmium, making them more environmentally friendly.
• Offer higher capacity and energy density, and are less prone to memory effects compared to NiCd batteries.
• Generally, provide longer runtimes on a single charge and are considered a greener alternative.

Compatibility Issues

Replacing NiCd with NiMH batteries isn&#;t straightforward due to differences in charging algorithms and discharge profiles:

• Voltage Similarity: Both types of batteries typically offer similar voltages, which might suggest compatibility. However, NiMH batteries often have a different discharge curve, which can affect device operation.
• Charging Requirements: NiMH batteries require a different charging protocol. NiCd chargers may undercharge NiMH batteries or overcharge them, leading to reduced battery life or potential safety issues.
• Device Sensitivity: Some devices designed specifically for NiCd batteries might not perform optimally with NiMH batteries due to differences in output characteristics.

Benefits of Switching to NiMH

• Environmental Impact: NiMH batteries are more environmentally friendly than NiCd batteries as they do not contain toxic cadmium.
• Enhanced Capacity: They typically offer higher capacities, which translates to longer use between charges.
• Reduced Memory Effect: Modern NiMH batteries are much less susceptible to memory effect, allowing more flexible charging without significant loss of capacity.

How to Switch from NiCd to NiMH Batteries

1. Check Device Compatibility: Ensure the device can handle NiMH batteries in terms of voltage and charging requirements. Consult the device&#;s manual or manufacturer if necessary.
2. Update Charger: Use a charger that is specifically designed for NiMH batteries to ensure they are charged correctly and safely.
3. Test Performance: Initially, monitor the device&#;s performance with the NiMH battery to check for any operational issues.
4. Battery Disposal: Dispose of NiCd batteries properly due to their toxic cadmium content.
