Duracell Rechargeable 9V Battery (6HR61) - 1 Pack

What you are buying here is one rechargeable 9V battery, made by Duracell and rated at 170mAh. The retail pack carries the codes 6HR61 and DC1604, which are the two industry references quoted in an equipment manual for this size, so they are worth checking against whatever you are fitting the cell into. A milliamp-hour figure is a capacity rating: it states how much charge a cell holds, which makes it the number to compare when you are weighing up one rechargeable 9V against another. This listing is a single cell in a hanging blister pack, not a multipack.

The 9V shape is unmistakable, a small rectangular block with two snap studs on the top face, and it is the format used by smoke alarms, guitar effects pedals, multimeters, radio microphone transmitters and a good deal of small test equipment. A rechargeable cell earns its keep in whatever you flatten most often, because the same cell goes back in after a charge rather than into the bin. Kit you fit once and leave alone for years is a different case entirely. Whichever you are dealing with, the manual for your own equipment is the thing that tells you which cells it will accept.

Rechargeable cells need a charger built to take them, and there is no charger in this pack, so plan on having one already or buying one alongside. The pack prints "Long Lasting Power Guaranteed" and nothing further about chemistry, charge time or how many cycles to expect, so we are not going to quote figures the manufacturer has not given us. No shelf life is printed on this pack either. We sell these in multiples of ten, which is a sensible way to buy them: keep a charged spare beside the device and rotate the pair, and you never lose an evening to a flat battery.

Does a charger come with it?

No. This listing is the cell on its own, so you will need a charger that accepts rechargeable 9V cells before you can put charge back into it.

What sort of equipment takes a 9V battery like this?

The 9V block format is the one used by smoke alarms, guitar effects pedals, multimeters and radio microphone transmitters. Check your own manual for which cells it accepts.

What does the 170mAh figure actually tell me?

It is a capacity rating, meaning how much charge the cell holds. Use it to compare one rechargeable 9V against another rather than against a single-use cell.

Is this one battery or a multipack?

One battery. Each pack holds a single 9V cell, and our minimum order is ten of those packs, bought in multiples of ten.

How many times can it be recharged, and what chemistry is it?

The pack does not print a cycle count or name the cell chemistry, so we will not quote either. It gives the codes 6HR61 and DC1604 and the 170mAh rating.

How should I identify the right replacement in future?

Match either code printed on the pack, 6HR61 or DC1604, along with the 9V size. Those references are what equipment manuals and stockists work from.
