In the past (and when on sale) I would buy ROV batteries...and they
would always fail prematurely for me.
Then I would think to myself, how could a big company still be in
business that made a faulty product. So I would try again.
Last time was a 5 year rated lithium 9Volt I put in a smoke
detector...it failed (detector started short beep) after 2 weeks!
I don't have problems with Duracell or Energizer. (I don't own stock
in these companies)
I've heard from other people that Energizer quality are
better. Can't say, I havn't done any testing. However, I've
had some bad ROV battereis, AAA, from Real Deals Dollar
Store. But, 20 battteries for a buck, I can't complain too
loudly. They were probably long out of date.
I've had so many Duracells leak,I don't use them anymore.
I've had good luck with Fuji Novel and Ray-o-vac.
Everready are OK,but more expensive.
Harbor Freight alkalines leaked while still in the packaging.Avoid them
like they had plague.
Anybody who is still using disposable batteries is insane. For the price of a
a few replacements, you can get a set of rechargeable that'll last years. I use
rechargeables in everything down to my universal remote controls. They've paid
for themselves many times over.
I love rechargeable batteries, the only problem I have
with those wonderful things is the two legged dumb asses
who come along and throw them away. I worked at a place
years ago where the goofballs would toss the rechargeables
and put disposables into my recharger. Unfortunately,
the legal system in this country takes a dim view of
what I consider justifiable homicide.
In general, I agree, and I have plenty of rechargeables. I do have a
few uses where rechargeables simply don't cut it. They have a
different output curve, and they also self discharge faster. For
things such as smoke detectors that are very low drain but need long
life in standby, a regular Alkaline is still superior. I also have a
marine VHF handheld that was designed for the output curve of
alkalines. Fully charged NiMH batteries have lower initial voltage,
and it is enough of a difference that the low battery alarm is on from
the minute you put them in. I also don't use the radio very much. I
just carry it on the dinghy, for "just in case". I put a fresh set of
alkalines in that every spring and they are still okay when I haul the
boat out in the fall. I then use up those batteries in other things,
like my digital kitchen timers.
1) Flashlight left in the vehicle for a year or so, and
expected to work.
2) Devices taken on a camping trip with no charger nearby
3) FRS walkie talkies stored in the glovebox, and needed at
In certain applications, rechargeable won't cut it. Their charateristics
is different. I frequently use Lithium batteries. I have some
rechargeable too. It all depends. I am not insane. My universal
remote(Harmony) sits on it's own cradle with built-in rechargeable.
No argument there. I use disposables for the smoke alarms and
anything that doesn't get regular use (flashlight in the car was a
good example). Maybe 4% of the batteries in my household. Everything
that actually involves regular use gets rechargeables, including the
Your average grocery supermarket probably turns over more batteries
than a typical Radio Shack location. That whole "Radio Shack batteries
are fresher" was a PR campaighn by Radio Shack. It's BS, and very easy
to disprove. All consumer batteries have expiration dates on the
