Review: Watch battery replacement. - Battery for my watch. OK price and quick delivery. No issues.
Review: A classic battery in the CR range - small but reliable - The Energizer CR1620 is a coin-like 3 volt cell used in various watches, calculators, PDAs, medical equipment, remote controls, electric earings, etc. The 'CR' in its type-code simply means that it uses lithium-manganese dioxide chemistry, the number denotes its size: 1620 = 16mm diameter, 2.0mm height. Its typical capacity is 78 mAh with a standard discharge current of 0.1 mA. The battery is clearly marked as positive (+) on its bottom and sides, and negative (-) on top, so inserting it correctly should be no problem. I fitted the CR1620 to an old Psion Siena PDA in just a few seconds; fitting one to my Timex watch took a little longer. I've heard that it's recommended to not touch the top and bottom (or do so as little as possible) so as not to leave a greasy residue on the contacts from your fingers. Inserting the cell holding only its sides proved to be a little tricky but not an insurmountable task. It's a great little battery. I bought a few for my battery 'arsenal' ... just in case.

## Questions & Answers

**Q: is it fit citroen picaso**
A: This would probably struggle to provide sufficient power to start a Citroen Picasso.  I'd suggest using a crank lever or tying a kite to the battery during a storm.

**Q: would this fit a citroen c3 55 plate? thank you**
A: Which part is it for?

**Q: Will this fit a mazda 2?**
A: If you ask a Mazda dealer if the Battery in the Mazda 6 key fob fits the Mazda 2.  This battery I purchased a while back from Amazon and it's working great in my Mazda 6.  Tip:  Once you remove a key battery, have the replacement in quickly and do not press any buttons.  You could remove the residual charge meaning he fob will need re-programmed.  It's not cheap

**Q: Will this fit a Mazda 3 2011 car key fob?**
A: No.

### ⭐⭐⭐⭐⭐ Works
*by T***R on 9 July 2024*

My garage charges over 20 quid to replace a battery in a car key fob. Hmm. I watched a few youtube vids on how to open the key fob -they're all different - and felt confident enough to poke a screwdriver into the fob's innards and prise out the dead battery and replace it with this one and, bingo, the car opened again. Job done. Very happy.
