377 Battery vs 377a Battery | Comparison
These batteries can befriend any brand. However, there will always be some differences. I hope you won’t mind getting them one by one below!
Let us talk about the 377 watch battery dimension. The capacity of this silver-oxide battery is 28 mAh. It is 2.6mm or 0.102 inches in height, and the diameter is 6.8mm or 0.267 inches.
On the other hand, the capacity of a 377a battery is 28 mAh. Like the above one, the height of this battery is 2.6mm or 0.102 inches, and the diameter is 6.8mm or 0.267 inches.
Voltage and Stability
As a silver-oxide or lithium battery, the 377 battery is more capable of providing stable voltage. In other words, as an alkaline version, the 377a battery is less capable and sturdy in this regard comparatively. And both batteries feature 1.55 voltages.
Generally, the 377a batteries last for around 5 years. It is almost true for the 377 batteries. However, concerning this, the latter one is comparatively more reliable. These batteries usually survive for more than 5 years on average!
The 377 battery is a direct replacement for a number of batteries. You would love to see how wide the range of its replacement is! These are as follows:
SR626SW, SR66, L626, SG4, SR626, BA, V377, D377, GP377, AG4, AG-4, 377, LR626, LR66, SR628SW, E377, E377CA, LR626SW, 377X, 377S, 606, S626E, GP177, SR6265W, 377/376, SB-AW, 280-39, E377A, SR66SW, SR625SW, 377A, SR262SW, 377BA, CR626SW, AG4/377, AG04 batteries.
On the contrary, the 377a battery is a direct replacement for the following batteries:
SR626SW, SR625SW, 377BA, CR626SW, SR66, 280-39, BA, V377, D377, 606, AG4, AG-4, 377, L626, SG4, LR626, LR66, SR628SW, SR626, SB-AW, E377, E377CA, LR626SW, 377A, S626E, GP377, 377S, GP177, SR6265W, 377/376, E377A, SR66SW, SR262SW, 377X, AG4/377, AG04 batteries.
Generally, these batteries are known as watch batteries. However, you can employ them in other stuff as well. You can use the 377a battery in some devices such as –
On the other side, you can apply the 377 batteries in devices such as –
- Talking children’s books
- Medical devices
If you want to learn about the price, you will have to go toward specific brands. There are several brands on 377 and 377a batteries. In this regard, we would like to exemplify the Energizer battery. An Energizer 377 Watch Battery (pack of 5) costs around $10.
On the contrary, a Duracell 377a Button Battery (2 Counts) costs around $5 – $6.
Perhaps, these prices will be sufficient to develop an average idea.
Good news for you! You would be glad to know that some of the brands like Renata ensure environmentally-friendly batteries. Moreover, a number of OEM or Original Equipment Manufacturer customers approved it. The fact is- zero lead plus zero mercury results in an eco-friendly product. So be sure that Renata 377 will cause no harm to the environment.
On the other hand, you will have 377a batteries similarly eco-friendly, no matter whether the brand is Renata, Energizer, or something else.
And both the batteries mentioned above are recyclable. This feature saves a lot of energy. So you may regard them as a standard one.
To Sum Up
These were the most substantial differences between 377 and 377a batteries. So from now on, no more confusion, no more mistakes. Now you are aware of the contrast in terms of dimension, voltage, stability, equivalence, applications, price, and so on.
Hopefully, all these could make your landing successful.
Have a nice day!
