## Description

A 2 volt 5 Ah pure lead sealed lead acid battery used in general applications such as emergency lighting UPS systems electronic equipment etc.

Review: Direct Replacement - Battery is used as a pair inside an Endodontic device that controls a temperature probe Batteries are hooked in series.
Review: Durable and reliable over 40 years of service - I have used these batteries as ignition source for model aircraft for over 40 years. They are durable, hold charge for years. I recently dug up a 40 year old Cyclon and it took a charge and held it.

## Features

- Power density - Per unit weight, the power provided by pure lead-tin products offers the greatest high-rate power density for your energy dollar. CYCLON's greater volumetric power allows engineers to consider more energy-supporting features.
- Cycle life - Compared to competitive lead products (offering up to 200 full cycles), pure lead-tin batteries provide 50% to 200% greater full cycle capability. CYCLON product will deliver up to 300 cycles (100% DOD, C/5).
- Float life - Conventional sealed-lead batteries vary greatly in specified standby life: from three to six years at 20oC, C/20. CYCLON Single Cells, however, offer a ten-year design life at 25oC, C/5, to 80% of rated capacity.
- High stable voltage delivery - The high stable voltage delivery of a pure lead-tin battery results from its low internal resistance. The flat discharge voltage profile of our batteries, similar to Nickel Cadmium.
- Safety - Since CYCLON Single Cells and Monoblocs emit minimal to no gassing under normal charging conditions they are safe for installation in offices, aircraft cabins, hospitals or any other environment occupied by human beings.

## Questions & Answers

**Q: running 6 in series for 12v, what is the maximum amp level for charging these batteries?  750ma too much?**
A: No, you are fine with 750ma

**Q: Looking to replace the 2 volt 2.5 ah batteries in my quantum 1 battery pack, will these work? i'm thinking the 5ah would provide faster cycling, etc.**
A: There is a size difference. 
The 2.5 ah battery is 	1.35 x 1.35 x 2.68 in
The 5 ah battery is              1.8 x 1.8 x 3.2 inches

**Q: When is the production date of this battery?**
A: Label attached to Battery (voiding Warranty if removed) on a fairly recent purchase is dated 10/26/2016.  Assume distributor's inventory continually rotates / expiration date moves forward.  My experience has been Battery life / label expiry date are not the same > @ +charge recycled per device guidelines maintaining optimal performance & extending lifetime use.  (:

**Q: what chargers are people using on these?**
A: Most all chargers used on these are product specific and not external chargers.
