Tenergy NiMH Battery Pack 12V 2000mAh High Capacity Rechargeable Battery w/Bare Leads Replacement Battery Pack for DIY, Medical Equipments, LED Light Kit, RC Models, Portable 12V DC Devices and More

I have actually ordered this item twice. Works great and I have had no problems with recharging the battery pack. Great value and a great product. I am so happy with this product and have repurchased it twice.

Someone recommended this to me. Glad they did. No disappointment. Came ready to use, fit exactly same as unit it replaced. I got the charger in a bundle too. Works great

im happy with this pack and the performance. the only thing i don't like is how think the wires it comes with are so thin. so far i haven't had any issues but i may have to solder on some thicker leads in the future.

This is new so cannot rate for longevity and battery life. So far it's been good. I have it hooked up to a small meter. Actually a Vapor meter for motorcycles and ATV's. That's installed on a ATV without a battery. The internal battery of the meter doesn't seem to last and the meter acts funny when the battery gets low. So though I would bypass the electrical system of the quad and run off this battery. This battery is a 12 volt, but very small. 2 3/4 long, 2" high, and 1 1/8 deep. The battery in the meter is dead and has been connected to this battery for 2 weeks. Went from 12.80v to 12.79v. For most of the time it has been keeping the time. I have made the meter turn on twice and think it takes 5 minutes to go back into sleep mode. So that's all the power it's used. I did had to buy a special battery charger to charge this battery back up. Will try and update down the road after unit is put in use.

Wired it with a Baja designs ac/dc rectifier, to charge 12v and supply my Baja designs squadron pro head light. Holds a good charge after a while of sitting. Lost my other one so I bought a second after having the first for 2-3 years and it still worked!

I was hoping I could connect this with wire connections for the stupid Coleman hot water supply self-care unit as we all know they're impossible to find batteries for and it didn't work out. My bad I don't know if it's good for anything else I'm sure it is I took a shot in the dark.

I used this battery pack to power a large boom box and it is working fine for me. The new pack is about 14.5V on a full charge even under load. There seems to be many warnings about heat, but mine only gets comfortably warm on the recommended 1A charging current with the recommended charger. It does require like 3.5 hours to achieve a full charge, and I suspect the heat warnings apply if you are trying to fast charge at 2A. The 2000mAh rating has plenty of capacity for my audio application.

Long life great value
