Energizer CR1620 3V Lithium Coin Battery

All good

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.

They arrived as described.

Did what supposed too

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.

Good brand
