1127706 2010-08-14 10:19:00 Yes I appreciate the obvious answer is when they don't hold a charge but......

Rechargeables claim to be good for hundreds of charges. However in my experience this is questionable. The ones I've tried become useless after two or less years intermittent use.

My use of batteries - apart from the remote control :D - is in digital cameras and the odd torch. These items are used occasionally, sometimes sitting on a shelf for two months. Then I find the batteries can barely function.

Any thoughts?

1127707 2010-08-14 10:28:00 plenty of thoughts,though none currently about batteries.


Muhahahahaha

1127709 2010-08-14 10:45:00 Sanyo Eneloops are good,low loss in storage and usually need a lower charge rate charger as fast charging kills Ni-MH's

There are other brands that now compete with Eneloop's

Back in 2003 I got my digital SLR and I had other stuff that uses AAs, like the external flash. At the time Sanyo Industrial grade batteries were well regarded, I didn't use it much but now they hardly last, I think with my battery charger it says it is a very high Mah still but they just discharger over a v short period of time. Not sure if they were like that at the start, b/c I didn't use them often. Heck, I bought more than I needed cos I imported them so I bought more thinking I would grow into them, I thought I would end up with 3 external flashes, haha, plus some of the higher film SLRs uses AAs, I still shoot that stuff ;) transparency film that is, with plans going to larger film sizes.

2 months? You are doing well. Mine discharges within a week or two.

1127711 2010-08-14 11:05:00 Rechargables are better for those devices that get regular use, and regular charging.

Items that sit untouched for months, and are then expected to work the moment they're turned on are best fitted with conventional batteries, coz you simply can't trust a rechargable to hold its charge over months.

1127712 2010-08-14 11:24:00 Mine are rubbish now. I went overseas last year, I freshly charged them up in Japan and popped them into my Garmin GPS. I only turned it on a few times a day, before the night arrived like 4pm, it was saying low in battery. Generally the Garmin says it allows you to use it for 12hr with one set of battery. Bought a set of Energizers I think they are, maybe similar to Enloop technology at the local supermarket - brilliant. Nomad (952)
1127713 2010-08-14 11:32:00 Junk batteries perform like junk. Most "economy" Ni-Mh batteries leak away their charge pretty smartly. Sanyo Enerloops (and maybe some equivalents) hold their charge very well. For something that is used intermittently and is inconvenient to swap batteries, the Panasonic Alkaline batteries seem to me to be best in value. (My laptop mouse with it's single AA Panasonic started flashing it's red warning LED in the last couple of days - it is a bit over 3 years old.) Lithium batteries are pretty good for retaining their charge, but a bit expensive if you don't really need that charge density. R2x1 (4628)

I guess the answer is similar to the conditions faced by laptop batteries.

If the rechargeable batteries are constantly exposed to heat, re-charged at 98% (OCD), or subjected to environments that are regarded as damaging to the batteries, then their lifespan would shorten considerably shorter.
