How long should new batteries last?

Bob says battery should last at least a year. When replacement is needed, there is a round indent at the bottom end of the housing. Push the indent with a pen or pin and pry off the back cover. Slide out the old flat battery and slide in a new one. The battery can be found at any department store or Lowe's/Home Depot. The battery number is CR2032.

Normally brand new batteries from Medtronic have a 5 year shelf life. When in a unit this time will probably be less due to use, as long as the unit shows it is okay the battery should be functioning normally

If fully charged and used at 2 LPM the battery should last 4 hours in your ever go. Two batteries would be a total of 8 hours use.

I am getting about 10-12 minutes per battery, but I charge them and then they sit for a week. You may get more time if you charge the batteries 12-24 hours before using them. Also keep them in the house if you live in a hot climate. Storage temperature may affect battery life. B&D; also claims the batteries reach full potential after 5-6 charges, but there is no empirical evidence of that.

Depending how long you have had it the battery may need replacement. Keep in mind rechargeable batteries have a limited number of charges depending on the model. Some are 50 some 100 charges. Also unless you have a special trickle charger you may decrease battery life if you keep a rechargeable battery on charge for more than 2-3 days at a time. This holds true for most rechargeable batteries.

I purchased two cameras just over a month ago and have already replaced the batteries three times. I would imagine they should last a lot longer than 2-3 weeks. I'm going to use rechargeable batteries from here on. If I hadn't missed the 30 day return window, I would be returning my two cameras.

Well in my opinion the battery during more time already i buy alkaline batteries. The time duration is between 45 minutes or 1 hour. I think you should buy alkalines batteries. Thanks.

Not a expert but my experience w/ similar type emergency lighting batteries is 2-4 yrs. They actually would last longer if receiving a discharge/charge every 3-6 months. Probably why people report these go bad after 3-4 yrs because they rarely get discharged/charged. If you do buy a spare keep it in a cool place and that will help the shelf life.

i would recommend getting the OEM batteries also. i have 4 of these batteries and they've lasted anywhere from 3 days to 10 weeks tops. And the charging cradle for it isnt great either. it takes at least 5 or 6 hours to fully charge ONE battery.

My recent experience was: first set fresh batteries - just under one hour, second set fresh batteries - one hour 10 minutes. So, it will vary within a 10-15 minute range.

Best to use Duracell (4) AA batteries. They should last 20-24 hours if new. Keep recirculating them as they loose power within the unit for max. use. I always keep an extra set in my carrying case for back-up and change after the ones in my unit are about 1/2 life left. You can use rechargeable but they won't last as long and you need to charge them up before you go out for max. efficiency. Happy Hunting!!!

I put new batteries in last year after I first installed the lights. I am still using the same batteries. Usually I leave mine on for about 2 hours at a time. I've probably used mine 6-7 times so far with the same batteries.

I have only had mine, a P7 for a few days so I really can't say how long the batteries will last. It uses regular alkaline batteries so they are cheap to replace.

I'd guessitmate about 6 months. It's not an issue, in general, I don't feel like I am putting in a new battery often.

Part of this answer is going to depend on the quality of battery you buy. here is my experience. I used Energizer batterys for the week of my vacation. The radio was on for about three to five hours for five days (20 hours or so) When I got home I took the batterys out and went back to using the cord because the radio stays in the house. i tested the batteries and they still showed an almost full charge so I put them with my spare flashlights. I would guess that the batterys would have lasted better than twice the time I used them for.

First time on a new battery about 4-6 hrs...after that about 1.5-2 hrs. Depends on the age of your battery.

Forget that battery and buy an 8 pack of AAA HD batteries from the Dollar Store for a buck. It will last about 2 weeks or more depending upon use.
