Never mix batteries of different chemistries, i.e. NiCd, NiMH, Lithium, etc. Never DROP the battery if you can help it as NiMH batteries damage internally quite easily.
Are NiCd and NiMH batteries interchangeable?
To some degree, Nickel Metal Hydride (NiMH) is interchangeable with Nickel Cadmium (NiCd) — with caveats. The issues related to replacing NiCd with NiMH are the charge methods, the discharge characteristics (specifically rate capability) and then the effect of both on cycle life.
Can NiMH batteries be charged with a Nicad charger?
Never charge Ni-MH batteries with a Ni-Cd charger. There are significant differences in charging conditions between those two types of batteries.The charging of batteries with an unsuitable charger may cause leakage or degeneration of battery service life.
Is it okay to mix battery types?
A: As chemistries and voltage vary across both battery types and brands, we recommend that you do not mix batteries. Mixing of cells can result in battery leakage and sub-optimal device performance.
What happens if you mix rechargeable batteries?
Don’t mix battery chemistries.
Using batteries of different chemistries to power a product can cause damage to your device from electrolyte leakage and over-discharge of the lower capacity batteries. Basically it makes a mess and eats the battery contacts, potentially ruining your product.
What is the difference between Ni Cd batteries and NiMH batteries?
Nickel-metal hydride (NIMH) batteries have a higher capacity than nickel-cadmium (NICAD) batteries, which means that they can generally power your device for longer. They also don’t suffer from the same memory effect, so they won’t “forget” the ability to achieve a full charge over time.
Can NiCad batteries be replaced with lithium?
Lithium-ion batteries and NiCad batteries are interchangeable because they are sharing the same features and qualities. Though, their formation is different so, it is dangerous to put both batteries at the same time.
Can I charge NiMH batteries with any charger?
No – any type of charger suitable for NiMH rechargeable batteries will charge either stay-charged or standard rechargeable batteries.
Do NiMH batteries explode?
Generally, the NiMH rechargeable batteries rarely leak, unlike alkaline batteries. However, both alkaline and rechargeable batteries contain electrolytes, which could induce leakage when the batteries are used incorrectly. By this logic, nickel-metal hydride batteries may explode.
Do NiMH batteries get hot when charging?
My Uniross Ultra Fast Charger says in the instructions that batteries will become hot during the charging process and this is normal and to disconnect the charger at the end of the charge cycle and allow batteries to cool before handling. They get pretty warm, but not actually too hot to pick up.
Do not mix old and new batteries?
Never use old and new batteries together, as this may cause leakage or worse. The remaining electrical capacity in a used battery is less than a new battery, even when it was only used shortly.
Can you mix batteries with different ah?
You cannot connect batteries of different amp-hours in series with good results. We strongly recommend you DO NOT attempt to mix battery sizes (amp-hours) and connect together. Due to differences in battery management systems and battery cell counts, there may be a charging and voltage discrepancy between batteries.
What happens if you put two batteries in parallel?
When two or more batteries are placed in parallel, the voltage in the circuit is the same as each individual battery. That is two, three, four or more 1.5 volt batteries in parallel will produce a voltage of 1.5 Volts!
Can you mix regular and rechargeable batteries?
When recharging batteries in a charger, don’t mix rechargeable and disposable batteries. Disposal (alkaline) batteries are not rechargeable and should never be placed in a charger. Manufacturers also warn against mixing brands of rechargeable batteries in a charger.
Can you mix rechargeable batteries with different mah ratings?
Mixing batteries of different capacities will generally result in lower capacity battery drain first, while the higher one will not be discharged completely. This is not optimal usage and it’s not very good to recharge not-fully-discharged batteries. Therefore, mixing capacities is not recommended.
Can rechargeable batteries be used with non rechargeable batteries?
Yeah we all can mix Rechargeable with Non Rechargeable cells but we should not do that. There are many different types of Rechargeable and non-rechargeable cells so talking about all of them will not be possible in here but let me give you some ideas.
Is NiCad and NiCd the same?
The chemical reaction of NiMH in the positive electrode is very much the same as in NiCD, i.e. nickel oxide hydroxide (NiOOH).
Comparison Table Between NiMH and NiCd.
| Parameters of Comparison | NiMH | NiCd |
|---|---|---|
| Capacity | High | Low |
| Discharging rate | Higher | Lower |
| Cost | Expensive | Inexpensive |
| Toxicity | Less | More |
How do you tell NiCd from NiMH?
If the cell is good, you should know, by the capacity and size of the cell, what the chemistry of the cell is. If the batteries have a covering on them and it’s green, then it’s NiMH. Unless it’s a Sanyo or Panasonic industrial NiCd cus a lot of them had green wrappers too .
Do NiCad batteries have a memory?
The memory effect is observed in (rechargeable) nickel-cadmium and nickel-metal hybrid batteries. The true memory effect occurs only occasionally, however. More frequently, a battery may show effects that are merely similar to the ‘true’ memory effect.
Can a NiCad battery be restored?
Recondition restores NiCd batteries with hard-to-remove memory. Recondition is a slow, deep discharge to 0.4V/cell. Recondition is most effective in rejuvenating batteries that have not been exercised.
Can I use a NiMH charger for lithium batteries?
You can’t. NiMH cells are about 1.2v nominal, best trickle charged. Lithium Ion require a complex charging strategy, winding up at about 4.2v fully charged. So, a NiMH charger has neither the voltage or strategy to charge Li Ion.
