- the housing member includes a base member and a covering member having a peripheral edge secured to said base member,
- said base member has, at the four sides thereof, cut-up pieces located at the positions thereof outside of the external shape of the lead storage battery when placed on said base member, and
- one of said cut-up pieces has a printed pattern including contact members, and a chip resistance as the impedance means.
- 7. A preservation device for lead storage battery as set forth in claim 1, wherein;
- the housing member includes a base member and a covering member having a peripheral edge secured to said base member,
- the contact members and the impedance means are disposed on the inner surface of said covering member, and
- the impedance means is an adhesive tape resistance.
- 8. A preservation device for lead storage battery as set forth in claim 1, wherein the housing member is a case having a concave portion for housing the lead storage battery, and said case has the contact members and the impedance means.
- 9. A preservation device for a lead storage battery of the type including at least one negative plate, at least one positive plate, at least one separator between said negative and positive plates, an electrolyte impregnated in said negative and positive plates and said separator and held therein and limited in amount such that there is substantially no electrolyte liberated from said negative and positive plates and said separator, and external terminals having first ends respectively connected to said negative and positive plates and second ends exposed external to said battery, said preservation device comprising:
- an impedance connected between said external terminals of said lead storage battery while it is in storage after it has been fully charged;
- a mounting member mounted on the lead storage battery during said storage, and
- contact members secured to said mounting member and adapted to come in contact with external terminals of said lead storage battery, and wherein;
- said impedance means is secured to said mounting member and connected between said contact members.
- 10. A preservation device for lead storage battery as set forth in claim 9 wherein;
- the mounting member is a cap covering a portion of the lead storage battery,
- the impedance means is disposed in a concave portion formed in said cap, and
- the lead storage battery to which said cap is mounted, is housed in a housing member including a base member and a covering member having a peripheral edge secured to said base member.
- 11. The preservation device for a lead storage battery in accordance with claim 9, wherein said impedance means is a resistance.
- 12. The preservation device for a lead storage battery in accordance with claim 9, wherein said impedance means has a value such that said lead storage battery discharges with a current smaller than that corresponding to the five hour rate.
- 13. A preservation device for a lead storage battery of the type including at least one negative plate, at least one positive plate, at least one separator between said negative and positive plates, an electrolyte impregnated in said negative and positive plates and said separator and held therein and limited in amount such that there is substantially no electrolyte liberated from said negative and positive plates and said separator, and external terminals having first ends respectively connected to said negative and positive plates and the second ends exposed external said battery wherein said preservation device comprises:
- an impedance connected between said external terminals has been fully charged;
- said impedance means secured directly to said lead storage battery and having a first end connected to said first external terminal of said lead storage battery, and
- a covering member for covering said lead storage battery while it is in storage, having a connection member for connecting a second end of said impedance means to said second external terminal of said lead storage battery.
- 14. A preservation device for lead storage battery as set forth in claim 13 wherein the connection member comprises a pattern film printed on the covering member.
- 15. The preservation device for a lead storage battery in accordance with claim 13, wherein said impedance means is a resistance.
- 16. The preservation device for a lead storage battery in accordance with claim 13, wherein said impedance means has a value such that said lead storage battery discharges with a current smaller than that corresponding to the five hour rate.
